MPI Engine - What is it? Engines Hyundai: Hot Hearts Korean "Modernity The basic principle of operation of the MPI system.

10.04.2021

Multi Point Injection - New type gasoline engine with pre-installed multipoint fuel injection system. In each cylinder, the built-in injector, as a result of which the combustible mixture is evenly and proportionally distributed around the perimeter. The inventor technology is considered to be the company's engineers. They are the first who developed an alternative to carburetor type. About how MPI engine works, and how effective it is, consider it more detailed.

As far as Multi Point Injection meets modernity

A number of automakers in Europe, Asia believe that such a type has no future, since the rapid development of technology will quickly leave behind the "novelty". Partly this is true. Actively develops and supports MPI only the Volkswagen concern and its structural divisions, including ŠKODA. Business card: Engine with volumes 1.3, 1.4 and 1.6 liters.

The main feature of the power unit in the absence of a turbocharged supercharger. The design is simple and intuitive:

the gasoline pump feeding the combustible mixture in the intake manifold under high pressure. The working indicator is three atmospheres;
through the inlet valve, the fuel fuel enters the cylinder, where there is ignition, the removal of waste gases.

Multi Point Injection is equipped with a water cooling circuit of a combustible mixture. It sounds unusual, it is difficult to imagine, but the system works successfully. The presence of a non-standard design is explained by the fact that over the head of the cylinder block increased temperature, and the fuel comes under low pressure. The consequences of negative, risk of boiling, the formation of a gas-air traffic jam. Without third-party cooler, the operation of the power unit is impossible.

Benefits MPI

easy design. Obviously, such engines are easier than power units equipped with TSI with turbochargers, but not a carburetor type. A number of repairs owners are carried out independently, without resorting to the help of specialists of a hundred. Explicit savings on monthly service;
the loyal attitude of the system to the quality of fuel. With regard to the CIS countries, where the fuel is not always "good", this option is acceptable. The power unit is quite comfortable working on gasoline of the AI-92 brand;
the average service life to overhaul is 300,000 km. Such numbers give the manufacturer. In practice, the resource is less than 50,000 km. Few people take into account the factor of timely replacement of motor oil, cleaning elements, refueling with high-quality fuel;
minimum risks associated with overheating;
the possibility of mechanical adjustment of the ignition advance angle;
the design involves the presence of rubber supports over the engine. This allows you to quench the oscillations, vibrations in the process of work.

Disadvantages of MPI

increased fuel consumption. The factor is quite controversial, one can interpret it in different ways. Compared from it increased by 7%. Many potential buyers frightens it, repels;
low torque indicator, and as a result, the average power factor. The fuel mixture is mixed directly in the inlet channels, and not in the cylinders. It is not atypically for most designs, it causes misunderstanding in TSI designers.

Cars with pre-installed MPI are not considered abrupt, fast, active. Rather, the average level is for connoisseurs of a slow drive, family holiday.

Statistics of sales on the CIS and the Russian Federation, including, shows that the owners of the priority still remains the power indicator than practicality.

Characteristic signs of MPI faults

reduction of power in the ride process;
increased fuel consumption;
on the center dashboard, the indicator is indicator about the presence of a fault "Check Engine";
the exhaust pipe comes out of blue, white or black. At the same time, this indicates a faulty injector and fuel equipment;
unstable work at idle;
difficult launch on the "cold";
increased working sound, vibration.

Frequent causes of breakdowns

violation, ignoring the timing of technical inspection;
third-party technical (mechanical) damage, accidents, collisions, strikes;
installation of non-original parts, components, consumables;
refueling with poor quality fuels with a high content of chemical impurities;
violation of the rules for using the machine, the power unit;
inconsistency of temperature modes, oil viscosity indices;
systematic loads over the norm.

Difference TSI and MPI

(double behind the layer injection) - TSI abbreviation is so deciphered. Such interpretation was served by Volkswagen engineers at the initial stage. After, renamed Turbo Stratified Injection. Now the abbreviation is used by many concerns, only with the addition of several letters for differences.

Differences between the two types:

TSI has a regular inflation system. In the engine at the same time there may be two supercharger: a turbocharged compressor and a mechanical type;
mPI lacks superchargers, they are not provided with design. If it comes to MPI, implies atmospheric type power units;
TSI puts forward a number of requirements for engine oil, viscosity coefficient, replacement frequency;
in TSI, fuel is injected directly into the cavity of the cylinder. For this, a special form is made, pistons, fuel injectors;
the MPI fuel comes in initially in the intake manifold, after which the cylinder at the time of opening valves. For such a design, the presence of a gasoline pump is not at all, since the standard pressure is enough to supply fuel.

When breakdowns occur, the MPI repair will be cheaper than the TSI cheaper. This factor has a lot of power, for many potential owners, it is fundamental.

To find out everything about the MPI engine, what it is, as he is arranged and by whom it is created, just read the material below. Such a power unit having an abbreviation MPI, which is certainly known to all car owners, is a German injection motor with a built-in multipoint system responsible for fuel injection. It is this feature of a power unit that just a few years ago was innovation, served as the basis for which the name of this type of engine appeared - Multi Point Injection.

Experienced vehicle owners know that in this complex device for each cylinder is provided. For the first time, the development of the scheme was engaged in Volkswagen. Automotive conmen, located in Wolfsburg, used the MPI system everywhere, since it used to be the only injection system with fuel injection.

The invention is recently considered to be a popular novelty, today is not an aggregate corresponding to the latest economic and environmental standards that are presented to all. The fact is that quite recently the device was removed from production, the last car, which was completed by the MPI engine, was the second Skoda Octavia series. However, talented constructors soon adapted the model of the power unit to new requirements, having revived the left MPI engine. At the moment, most often you can find the engine with a volume of 1.4 liters with an impact of 80 liters. from. and 1.6 l with a capacity of 105 liters. from.

Main characteristics

The MPI system, as mentioned earlier, is decrypted as Multi Point Injection, which denotes the presence of multipoint injection. The power device from is a gasoline nonurgicated unit, in which a point injection is operating while driving, which is distributed over all cylinders. This system implies the presence of cylinders, each of which is assigned a separate injector. Through such an injector, a dosage fuel supply occurs, which is carried out exclusively under pressure. The passage of fuel provides separate intake channel.

The design of the power unit is such that it does not have a fuel rail, which serves as the basis of the injection injection in TSI engines. Another feature of the MPI motor is the lack of direct injection, which goes into all cylinders (compared to). The feature and simplicity of the aggregate design led to the presence of the ignition advance function. In view of this circumstance, the throttle gained ideal sensitivity regarding the gas pedal.

A complex mechanism is completed with an extraordinary water cooling system. Volkswagen Concern installed in his device the MerCruiser system, stabilizing the correct performance of the power unit. With the help of such an element, the engine is freed from gas-air plugs.

Manufacturers of the modern MPI motor perfectly thought out all the components of the elements, equipping the system with a special controlling hydraulic drive and a separate coupling with a built-in press-oil. It is impossible to go around the differentiated engine, which basically contains rubber supports, automatically adjusted relative to the speed of movement, the speed of the power unit and the irregularities of the road surface.

All individual elements assembled into a single design, have a beneficial effect on reducing vibration and noise coming from the motor. The engine has 4 cylinders and 8 valves. At the moment, the aggregates of 1.4 liters with a return of 80 horses and 1.6 l - from 105 liters. from.

Advantages of the power unit

If a person acquires a car on the power unit of which the MPI designation is present, he needs to know what MPI means. Like any other device, the engine has a number of certain advantages and disadvantages. First of all, we consider the weighty advantages of the unit, which during operation allowed to collect a millionth crowd of fans, still preferring to move on vehicles equipped with MPI engines.

This type of engines among Russians is particularly popular, since in the Russian Federation the norms that are presented to the level of ecology have a number of sending, unlike European standards. In Europe, even closely does not have such a number of "antique" cars, such as domestic Russian "kopecks", mercilessly related to the environment. The thing is that fuel abroad is an order of magnitude cheaper.

Advantages of modern MPI devices:

the design that is not similar to a simple carburetor, but not so complicated as TSI, equipped with a variety of massive and "cunning" devices. A constructive simple unit is available in terms of cost, in view of which it has the possibility of budget repairs;
simple requirements for. MPI installed in any car can with a calm soul fill out by a simple 92-M gasoline;
stability of relatively premature overheating.

An important advantage of such an aggregate is to reduce noise and vibration, which manifests itself during movement.

Motor Disadvantages

All the disadvantages that the MPI device posses is directly dependent on design features.

Disadvantages of the system:

during the movement of the car, gasoline is mixed with air, it occurs in the channels, and not cylinders, which negatively affects the restriction of the capabilities of the intake system;
lack of power and lack of sufficient torque (directly related to the previous minus);
the absence of excellent indicators relative to the dynamics, drive and at least sports techniques.

All indicators are a bit aggravated by the amount of valves provided, for modern cars 8 pieces are simply not enough. A car equipped with such an aggregate can be called quiet.

Conclusion

All listed indicators affect the departure of the MPI engine from the world market. The ever-growing pace of development of powerful maneuverable cars, which prefers the majority of motorists, need a complete set of more "strong" power units, compared to which MPI motor is weak. However, it is still too early to write off this engine, if you consider the fact that on the Russian version of Skoda Yeti (family SUV) producers replaced the turbocharged engine with a volume of 1.2 liter MPI power unit with a volume of 1.6 liters with a return of 110 liters. from.

The developers of the updated engine MPI marked its indigenous difference from a predecessor with a capacity of 105 liters. With., assuring that the new unit belongs to the TSI family, with the only feature - lack of turbocharging and direct fuel injection.

Engine MPI in Volkswagen cars: principle of operation, features, advantages and disadvantages. The MPI engine is an injection structure that uses a multipoint fuel injection device. Therefore, this motor received the corresponding name "Multi-Point-Injection". In other words, its own injector-nozzle has been developed for each motor cylinder. This scheme was embodied by the Volkswagen autoconecer.

This type of engine is installed on the Volkswagen new Polo sedan, some sets of Golf and (partially Golf and Jetta are also equipped with TSI engines). On, Passat SS, installed now (2016) only TSI engines. On install FSI.

MPI motor device is the most obsolete from the entire Volkswagen motor range. But, nevertheless, it is characterized by excellent practicality and reliability. Some specialists note that now such a type of engine does not meet the current requirements in terms of economy and environmental friendliness. Moreover, it was also recently argued that such a type of motor was removed from manufacture. And the last automotive model of the autocontraser, where it was used, was Skoda Oktavia 2nd series.

But suddenly the MPI engine was revived and became demanded again. In the fall of 2015, Volkswagen launched the production line of motors at its Kaluga factory, where the MPI 1,6 series EA211 series began to produce.

MPI engine features

The main difference between such engines has already been written - this is a multipoint supply of gasoline. But those who are good with car engines may noted that the TSI motors also have multipoint injection.

Therefore, we turn to another distinguishing feature - there is no prediment to MPI. Those. There are no turbocompressors to pump a mixture of fuel to cylinders. Ordinary benzone pump that feeds fuel under pressure is three atmospheres in a special intake collector, where it is further stirred with air mass and is delayed through the inlet valve directly into the cylinder. As can be seen, it is sufficiently similar to the activity of the carburetor engine. There is no direct fuel injection into the cylinder, as in FSI, GDI or TSI devices.

Another feature is the presence of a water system, due to which the mixture of fuel is cooled. This occurs due to the fact that in the field of the cylinder head, elevated temperature is set, and the flow of gasoline is carried out under rather low pressure. Therefore, all this can boil and form gas air traffic jams.

Benefits

The MPI engine is distinguished by its own unpretentiousness to fuel quality and can work on the 92th gasoline.

By its design, this motor is very durable, and its smallest mileage without any repair work, as the manufacturer informs, is 300 thousand km, naturally, if oils are replaced on time, as well as filters.

Thanks to the not very complex design, the MPI engine in case of breakage can be easily repaired and in general it is noticeably reflected at its price. The usual design favorably distinguishes it compared to TSI, where there is an increased pressure pump and the turbocharger. MPI engine is also less prone to overheat.

Another advantage of the motor is the presence of supports from rubber located directly under the engine. This significantly allows you to reduce the noise and trembling during movement.

disadvantages

It can be noted that the MPI engine is not very dynamic. Due to the fact that the process of fuel mixing is carried out in graduation special channels (before the fuel fall into the cylinders), such motors are considered limited. The eight-glove system with a set of MRM speaks of shortages in power. Thus, they are designed for not very fast trips.

From the disadvantages you can allocate what MPI is less economical. Multipoint injection in its efficiency is inferior to the superior together with direct fuel injection into the cylinder, as is done in the TSI propulsion.

And yet, if we add advantages and disadvantages, it turns out that these engines are quite comparable in terms of competitiveness, especially for Russian roads. It is no coincidence that the German producers have abandoned the 1.2-liter TSI engine, preferred a proven and unpretentious 1.6-liter MPI engine.

Hyundai uses its own engines to install on its cars, which showed themselves from the best side. About how Hyundai engines equipped cars for the Russian market, about their basic characteristics, features and applicability, as well as general information on South Korean power units - all this you will learn from this article.

General view on Hyundai engines

Hyundai, like many other major autoconcers, equips their cars in their own production engines, which makes it independent of third-party manufacturers. However, it was not always possible: For many years, the company produced motors under the Mitsubishi license, and only in 1989 (22 years after the company's education) was released with a fully developed development.

To date, Hyundai issues the power settings of several types that have different purposes:

Row 4-cylinder petrol engines for small cabbage for passenger cars, minibuses and light commercial trucks;
. Row 4-cylinder diesel engines of small cubic machines for passenger cars, minibuses and light commercial trucks;
. Row 4-cylindower diesel engines of large cabbage for trucks;
. V-shaped 6-cylinder gasoline engines for passenger cars (including crossovers);
. Row 6-cylinder diesel engines of large cubic for powerful trucks and buses;
. V-shaped 8-cylinder gasoline engines for passenger representatives of the representative class;
. V-shaped 8-cylinder diesel engines for trucks and buses.

In addition, in the Hyundai line there are several 3-cylinder gasoline engines, as well as the mass of motors with a volume from 53 to 678 cm 3 (with a capacity of 2 to 30 hp) used on generators and small techniques (snow plows, motorwlters, motor-cultivators and etc.) But here we will talk only about car engines.

A - South Korea, Asan;
. B - China, Beijing;
. H - South Korea, Hwashan;
. K - USA, Montgomery;
. M - India, Chennai;
. P - South Korea, Posyung;
. S - South Korea, Sakhari;
. T - Turkey, IZMIT;
. U - South Korea, Ulsan;
. W - China, Shandong;
. Z - Slovakia, Zilina;
. 1 - China, Yangcheng.

Usually full marking is indicated only in the car documents, more often you can see engines with a four-digit designation, which is usually more than enough. For example, two motors are installed on Hyundai Solaris - G4FA and G4FC, this means that we have gasoline 4-cylinder gamma generation motors (what the letter "F") is 1.4 liters (letter "A" in the first motor) and 1.6 liters (letter "C" in the second motor).

Marking is knocked out on the engine, its location depends on the specific power unit. But usually the marking is applied to the block of cylinders in such a place so that it is visible without special manipulations - it is enough just to open the hood.

Engines current models of Hyundai passenger cars

Hyundai uses a wide variety of engines, while one model intended for different markets is often equipped with different motors. Therefore, here we will consider only those engines that are used on Hyundai vehicles intended for sale in Russia.

Each engine line has its own characteristics, specifications and applicability.

Line "Gamma"

The most common gasoline engines have relatively small power, small dimensions, low noise level and high degree of environmental safety. This generation has replaced the first generation of Hyundai Alpha gasoline engines. Engines have a number of general features and characteristics:

Row 4-cylinder;
. Petrol;
. MPI (multipoint injection);
. DOHC (two timing shaft in the head of the cylinder block);
. D-CVVT (System of changing the phases of gas distribution);
. 16 valves (four valves per cylinder);
. GRM - chain drive;
. Aluminum cylinder block and cylinder head.

The ruler includes three modifications - G4FA (GAMMA 1.4), G4FC and G4FC (both GAMMA 1.6). Motors are installed on the Solaris, Accent, Elantra, Veloster, I30, IX35, I40, as well as Kia Ria and Soul cars.

Line "NU"

One of the new developments of Hyundai, these gasoline engines occupied a "double-liter" niche between the Gamma and Theta II rules. These motors are equipped with the most modern systems and functions - MPI, CVVT, DOHC and others. The cylinder and cylinder block are made of aluminum, so the motors with good power indicators are very light and compact.

This line in the Russian market is represented by two models:

G4NB (NU 1.8, is installed on Hyundai Elantra);
. G4NE (NU 2.0 is installed on IX35 and I40).

Also, this generation includes more powerful two-liter Motors G4NA (164 hp) and G4NC (177 hp), which is equipped with no longer produced today Hyundai Tucson model and others.

Theta II line

Theta II gasoline engines are produced since 2008, they came to the change of Motors Theta, produced only four years. These power units have all the "family features" of Hyundai motors: an aluminum block of cylinders and cylinders, multipoint injection, two camshafts in the cylinder head, the MRM phase change system and others.

The ruler consists of more than a dozen motors, but today only 2,4-liter versions are supplied to Russia:

G4KE (put on the Santa FE crossover);
. G4KG (put on the minibus H-1);
. G4KJ (put on Hyundai Grandeur, previously this model was completed with a less powerful G4KE unit).

Also, theta II line includes 1.8 and 2-liter engines, but Hyundai does not offer the domestic buyer cars with these power plants.

Lambda II line

The line of powerful 6-cylinder power units installed, mainly in the expensive models of Hyundai and Kia cars. Motors are manufactured since 2008 (the first generation of Lambda has been published in 2006), they have the following features:

V-shaped engine (angle V 60 °);
. Petrol;

. Availability of models with MPI (distributed injection) and GDI (direct injection);
. D-CVVT (changing phases of gas distribution);
. Lightweight aluminum design;
. GHM chain drive.

Ten engines are present in the model range, but only four modifications are installed on cars for the Russian market:

G6DG (Lambda 3.0, is installed on genesis);
. G6DH (LAMBDA 3.3, is installed on the Grand Santa Fe);
. G6DJ (Lambda 3.8 is installed on genesis);
. G6DA-AC (Lambda 3.8 new version is installed on Equus).

Other engines of this line in our country are not supplied.

TAU line

The most powerful gasoline engines installed on the passenger cars of the representative class. Released since 2008, have the following characteristics:

V8 (V-shaped 8-cylinder, angle V - 90 °);
. Petrol;
. QOHC (four timing shaft - two in each head of the cylinder block);
. D-CVVT;
. Aluminum design;
. There are models with MPI and GDI.

The model range consists of only three engines, now Hyundai supplies only one of them to Russia - top 5-liter G8BE GDI installed on Equus. Also in the ruler there are less powerful G8BA and G8BB engines with the MPI system.

LINE "U II"

The simplest and inexpensive diesel engines are Hyundai intended for compact passenger cars. Motors are produced since 2004, have the following features:

Row 4-cylinder;
. Diesel;
. CRDI (Common Rail Fuel Instrument);
. Equipped with a turbocharger with variable geometry (VGT);
. Have a CVVT system;
. DOHC;
. 16 valves.

This ruler includes a large number of engines (more than a dozen modifications) with a volume of 1.1 to 1.7 liters. Cars entering Russia are currently completing two models:

D4FB (U II 1.6, 128 hp, installed on i30);
. D4FD (U II 1.7, 136 hp, installed on i40).

Also, some U II engines are installed on KIA cars. Despite the high interest of the domestic buyer to diesel engines, Hyundai supplies a very limited range of cars on this type of fuel into our country.

Rule "R"

More new and powerful diesel engines manufactured since 2009. There are a number of non-trivial design solutions, however, are generally similar to those described above motors (CRDI, DOHC, CVVT systems, turbocharger VGT, etc.). In Russia, the line is represented by three engines:

D4HA (R 2.0, 136 hp, installed on IX35);
. D4HA (R 2.0D, increased to 184 hp. Power is also installed on IX35);
. D4HB (R 2.2., 197 hp, put on Santa Fe and Grand Santa Fe).

Surely everyone knows what the motor is in the car. But today's article is devoted to a specific aggregate, about which we will try to tell from "A" yes "I"

The end of the past century and the beginning of the new one became a period of aggravated interest in MPI gasoline engines. Decoding this reduction sounds like Multi Point Injection. An extraordinary fuel injection scheme served as good demand for cars with such engines. This scheme was created in a multipoint principle.

At the expense of individual injectors in each cylinder, a uniform distribution of fuel in the cylinders is maximally possible. This construction development, namely, the release of engines with multipoint injection took over Volkswagen. Due to which the MPI engines appeared.

The emergence of such power plants was an alternative to carburetor engines. To more accurately understand the MPI engine, you need to carefully disassemble its competitive features.

Modernity Multi Point Injection engines

The future of MPI engines is missing, as it looked several years ago, many even believed that the manufacture of engines of this type was suspended. The radical development of automotive developments and technologies is very quickly forcing not to remember yesterday's quality reference.

In fact, this happens with MPI engines, many specialists in this industry argue that economy and environmental safety are outdated.

But these conclusions are more correct only for European markets, and as for the Russian, then it all looks in part. Since the real potential of these aggregates has not yet been fully detected by domestic motorists.

Manufacturers bet on foresight, do not die to die this technology and constantly introduce it to cars intended for Russian roads. For example, on Skoda Yeti or Volkswagen Polo. The most memorable became representatives of the MPI system with engines, the volume of which was 1.4 or 1.6 liters.

MPI engine design features

The absolute lack of turbocharger is another significant distinctive feature of this system along with the multipoint injection system. In the design of these engines, there is an ordinary benzonasos, which under pressure 3 of the atmosphere supplies fuel to the intake manifold for subsequent mixing and feeding through the inlet valve of the finished composition.

This work scheme is very similar to the scheme of the carburetor engines. With one difference that there is a separate nozzle on each cylinder.

Another not familiar feature of the Multi Point Injection engine system is the presence of water cooling loop for fuel mixture. This is due to the fact that in the area of \u200b\u200bthe cylinder head, a very high temperature, and the pressure of the incoming fuel is very small, because of this, there is a high probability of manifestation of gas-air traffic jams and running off.

Characteristic advantages MPI

Before transferring to a car with MPI, many motorists who are in one degree or another familiar with this system will think very well about obtaining a set of advantages, at the expense of which the installation with multipoint injection has deserved vocation in the world.

Easy device

This does not mean that such systems are easier compared to carburetor models. If you compare the TSI model, which has in the design of the TNVD and turbochargers, then naturally superiority on the face. And the cost of the car will be lower and reduced operational costs and the possibility of self-repair.

Undemanding fuel quality requests

Guarantee the proper quality of fuel and oils everywhere and is always not possible that very characteristic of Russia. The use of lowactane gasolines below 92 does not affect the operation of MPI engines, since they are very unpretentious. The minimum mileage of cars without breakdowns, according to the developers, is 300,000 km, provided that the oil and filter elements are timely replaced.

The minimum probability of overheating

The ignition advance angle is adjustable. The presence of an engine support system, which is designed to apply rubber supports. Of course, it is not related to direct with the engine, but on the performance of the motor and the comfort of the driver, it all matters.

Since the vibrations and various noises that occur when driving. An interesting feature is that supports have automatic tuning under various engine operation modes.

Characteristic disadvantages of MPI

All disadvantages of this engine are expressed precisely its constructive features. The fuel connection with air occurs in the channels, and not directly in the cylinders. Accordingly, there is a limitation of the capabilities of the intake system. This is expressed in shortness of power and rather weak torque.

Based on this, no decent dynamics, athletic pickup, hot drive is not obtained. In modern cars, the presence of eight valves is usually lacking, so all these characteristics increase. If you characterize this car with such a system, it will completely come down for family and calm transport.

That is why such cars ceased to be in demand and depart to the back plan in the past. Why is it happening, i.e. The world made an assessment of the qualities of this system and decided that it was not enough and designed by the developers to design more modern power motors. But no, there are unexpected surprises in the automotive industry.

Skoda developers developing a Russian version of the SUV for family use Yeti, in 2014 deliberately abandoned the turbocharged engine with a volume of 1.2 in favor of the MPI engine with a volume of 1.6 and 110 hp.

As stated by the developers of the famous World Concern, this engine practically has nothing to do compared to the old model with a capacity of 105 hp. It is most suitable for TSI models, but it does not have direct injection and turbine.

Summarizing

On the care of engines from the world market with the MPI system, the above listed indicators significantly affect. Nowadays, many motorists prefer more powerful modern cars, the pace of which is growing steadily.

The need for equipment of machines stronger aggregates significantly underestimates the cultivation of Multi Point Injection engines. Compared with them, this motor is weak. But MPI MPI is still too early to write off the MPI motor, since the developers of Skoda Yeti are trying to use it fully on Russian roads.
