Technical characteristics of the car Renault Logan Engine 1.6. Budget sedan Renault Logan I
Who would know that a trip to it will give so much emotions! And not only me: not to consider the amazed drivers of passing cars, who seen how easily and naturally, I started from the traffic light in the avant-garde of the flow - because Logan, as a rule, are not involved in such battles. But my car is completely different. Under the hood - 1.6-liter 16-valve engine with a capacity of 102 hp This is 15 "horses" more than the eight-point of the same volume that was the most powerful in the range. It seems to be a small increase, but it was enough that the character of the sedan has changed dramatically.
Unlike the source motor, which on turns above the average "does not live", this unit loves to be twisted. On small circulation, 1.6-liter engines behave similar, but after 3000 rpm in the 16-valve, tangible pickup occurs - the car wakes up as quickly, how fast accelerates. Run from space up to 100 km / h, according to factory data, - 10.5 s. Against the background of ordinary "Logan", such a speaker is like a blow to the Litavra after a thin ring of the bell. Perhaps, not many models of this price category can boast greater than more. Of course, the sports car will not be called, but the fact that the sedan is able to light in the heart of the driver of the light is quite accurate.
It is gratifying that in terms of efficiency, 102-strong modifications wins in 87-strong. For 100 km of urban ride, it requires 9.4 liters of fuel against 10 liters for an eight-point. At the same time, the car, as before, is content with 92th gasoline.
In traffic jams, the version 16v pleased with a good burden on the bottoms - you can get on the spot nearly at idle. And the clutch is configured, as it should: it works exactly when you expect. The five-speed mechanics still distinguishes clear switches and good selectivity. The transmission process overshadows only tangible vibration on the lever. He, by the way, is decorated with a pseudo-aluminum lining. And for the "beautiful life" - the skin-skinned steering wheel, a shank-white substrate of the instrument panels, on the threshold sticker with the RENAULT logo, and the central console is framed by insertion under Kevlar - an unexpected solution for the budget model.
Suspension of the flagship "Logan" - with a transverse stability stabilizer (SM, 2009, No. 11). Of course, it is noisy working out irregularities, but energy intensity seems to have no limit. To bring the suspension to breakdown, you need to try hard. I could not get.
In the city, full-fledged outer mirrors are helpful, installed instead of miniature "ears". The sixteenthly populated "Logan" is offered exclusively in the richest performance of Prestige - a driver's airbag, air conditioning, fog lights, heating front armchairs, an exterior mirror and glasses. Such a generous set causes a high price - "Logan 16V" costs from 414,500 rubles. For the machine of the budget category is expensive. Perhaps the company should offer a 16-valve modification in a simpler configuration. Then more buyers can enjoy the dynamics.
Renault Logan provides the buyer version with various engines and gearboxes, which, together with a variable package, allow you to pick up a car individually, under the requirements of each future owner. The very "top" version for this sedan is a variation with a 1.6 liter engine with 16 valves. About what technical characteristics such a car has and what opportunities it provides, read further.
Mass and dimensions
Despite the fact that such a car is positioned as a trouble-free and reliable family assistant, which, with regular maintenance, is capable of listening to faith and the truth is not one year. This sedan is compact and is not able to transport a large amount of baggage.
Nevertheless, according to those data, the engineers managed to create a sufficiently small car, which has a decent trunk volume and quite comfortable for five people salon.
One of the most important technical characteristics of Renault Logan is its length: the volume of the trunk, and the comfort of the cabin depends on this parameter. According to official data, this indicator is 4346 mm for the author provided. At the same time, the distance between the extreme points of the side mirrors is 1732 mm, and the maximum height is 1517 mm. At the same time, the road clearance in the Russian version is increased to 155 mm, which provides the car with excellent opportunities for overcoming light off-road and country rut.
The mass of Renault Logan, according to the list of those characteristics, without passengers and with an empty trunk, is 1127kg. If you make the maximum loading of the machine, then this parameter is able to increase to 1545kg. In this case, the volume of the trunk is quite solid: if you believe the table of technical specifications, on Renault Logan 1.6 it is 510 liters.
Engines and dynamics
For Renault Logan 16-valve 1.6 liter motor - not the only version that is offered for this car. However, the entire line of motors has similar to those data and is able to boast of high efficiency at sufficiently small working volumes.
So, all three engines have a cross location in the subcontrol space and are four-cylinder atmospheric power units that do not have turbocharging. At the same time, 8 or 16 valves are laid in the design, depending on the execution.
For motors, according to those data, a distributed injection system is provided, which is capable of improving the dynamic characteristics of the machine and increase its efficiency. By the way, the regulated fuel for all motors is AI92. However, if you believe the official documentation, the manufacturer allows the bay and 95 gasoline.
Renault Logan engine 1.6 liters with a 16-valve design, according to those data, is able to give the machine maximum for this model 102 horsepower, which are achieved at 5,750 revolutions per minute. The torque here is also maximum, and on the 16-valve motor 1.6 is 145 Newton meters: this figure can already be achieved at 3750 camshafts per minute. Acceleration to hundreds, according to the list of technical characteristics, is achieved in just 10.5 seconds. At the same time, the maximum speed reaches a lot of 180 km / h.
A separate word deserves fuel consumption: despite enough high power and excellent specifications, the 16-valve engine 1.6 remains fairly economical and will not require a large amount of fuel even with a dynamic driving.
So, according to passport data, in the city, the 16-valve will not consume more than 9.4 liters of gasoline for every 100 kilometers of the way. In a mixed cycle, this figure becomes significantly less and reaches only 7.1 liters. At the city, this figure is expected minimal and, according to the manufacturer, does not exceed 5.8 liters per 100 km of way.
Summing up
Summarizing, it is impossible to no longer note that Renault Logan is currently one of the most inexpensive, reliable and economical cars presented in the market. This allowed the sedan to achieve extraordinary popularity among buyers and earn an excellent reputation that continues to strengthen every year.
Renault Logan 1.6 8 8 valves appeared in our country with the first generation Renault Logan. Initially, the gasoline power unit K7M issued 87 horsepower, but today the same motor has a capacity of 82 hp. There are no errors in this difference. The fact is that in 2005 the motor corresponded to the ecological standards of Euro-2, and today corresponds to the norm of Euro-5. The power unit was more environmentally friendly, but the reconfiguration was deprived of the Logan engine of several horsepower.
Technical characteristics of Renault Logan 1.6 8 8 valves
Working volume - 1598 cm3 Number of cylinders - 4 Number of valves - 8 cylinder diameter - 79,5 mm Piston stroke - 80.5 mm Drum drive - belt Power hp (kW) - 87 (64) at 5,500 am. in min.

The main thing on time to change the timing belt, which is perhaps the main weak place of the engine.
Pluses of the engine K7M Renault Logan 1.6 8 valves
✔ Low price and reliability of engines design; ✔ Reliability: a confirmed motor is more than 400 thousand km; ✔ Universal and maintainable; ✔ simple maintenance; ✔ have a high torque; ✔ It provides good "elasticity" of engines, equal to 1.83.Minuses of the engine K7M Renault Logan 1.6 8 valves
✔ relatively high fuel consumption; ✔ There is instability of revolutions when working at idle; ✔ In the design there are no hydraulic components, so it is necessary to constantly adjust the valve (after 20-30 thousand km); ✔ There is a probability of valve bending with a sudden breakdown of the timing belt; ✔ The crankshaft seals often flow; ✔ Low reliability of the cooling system; ✔ Very noisy and prone to vibrations.If all regulatory work is carried out in a timely manner and according to the manufacturer's recommendations, the engine resource can reach 400 thousand km, which is confirmed by real numerous examples. The only unpleasant surprise may be the breakdown of the timing belt, evidenced by reviews. In the case of such an accident, pistons face valves, causing their bend or complete destruction.
Engine Renault Logan 1.6 8 CL. Petrol, four-stroke, four-cylinder, row, eight-flaped, with the upper arrangement of the camshaft. The order of the cylinders: 1-3-4-2, the countdown - from the flywheel. Supply system - distributed fuel injection MPI. The engine with a gearbox and clutch form a power unit - a single unit fixed in the engine compartment on three elastic rubber-metal supports. The right support is fastened to the bracket on the top cover of the drive belt of the gas distribution mechanism, and the left and rear - to the card of the gearbox. The engine cylinder block is cast from cast iron, cylinders are boring directly in the block. The nominal cylinder diameter is 79.5 mm. In the lower part of the cylinder block, there are five crankshaft root bearing supports with removable lids, which are attached to the block with special bolts. The holes in the cylinder block under the bearings are processed when the covers are installed, so the covers are not interchangeable and for differences are marked on the outer surface (the lids account is conducted from the flywheel side). On the end surfaces of the middle support, nests are made for a stubborn semi-colts that prevent the axial movement of the crankshaft. Inserts The root and connecting rod bearings of the crankshaft steel, thin-walled with antifriction coating applied to work surfaces. Crankshaft with five root and four rod cakes. The shaft is equipped with four counterweights, cast at the same time with him. To supply the oil from the root neck, the channels, the outlet holes of which are closed with plugs are served. At the front end (sock) of the crankshaft set: an asterisk of an oil pump drive, gear pump pulley of the gas distribution mechanism (timing) and pulley of the drive of auxiliary aggregates. In the hole of the gear pulley there is a protrusion that enters the pier on the sock of the crankshaft and fixes the pulley from turning. Similarly, fixed on the shaft and pulley of the drive of the auxiliary units.
Renault Logan Motor Lubrication Combined. Under the pressure, the root and connecting rod crankshaft bearings and the camshaft bearings are lubricated. Other engine nodes are greased by splashing. The pressure in the lubrication system is created by a gear oil pump located in front of the crankcase pallet and attached to the cylinder block. The oil pump is driven by a chain transmission from the crankshaft.
The timing of timber on Renault Logan 1.6 8 valves is carried out according to the following scheme (the image is slightly higher) - the torque of the crankshaft pulley is transmitted to the pulley of the camshaft rotating the plot of the coolant pump. The belt is stretched by a special roller, which changes with the timing belt. In the event of a belt break of the valve. Therefore, in accordance with the regulation of the car maintenance of the car, conduct a belt state check every 15 thousand km of mileage. The surface of the toothed part of the belt should not have folds, cracks, fermented feeds and tipping tissue from rubber. The reverse side of the belt should not have wear, exposing the filament of the Cord, and the markup traces. On the end surfaces of the belt should not be observed with bundles and grinding. The belt must be replaced when traces of oil detecting on it. Regardless of the state of the timing belt Renault Logan, it must be replaced every 60 thousand km of mileage.
Malfunctions and repair of the engine Renault Logan / Sandero 1.6 K7M
RENAULT LOGAN K7M 710 engine 1.6 liters. 86 hp Not other than the usual K7J 1.4 liter, only with an increased piston running (from 70 to 80.5 mm), by itself the height of the block slightly increased, the adhesion of the larger diameter, the flywheel increased and the shape of the CATER CTP has changed. Structurally engine Logan 1.6 liters, as well as his low-volume fellow, has all the same archaic design of the middle of the last century with a rocker and a strange oil pump drive from the lower reno of motors of the 60s. In spite of everything, with a careful attitude to the motor, service and maintenance, replacing the oil 2 times more often than according to the instructions, it is very and very reliable, according to the internal data of the engine of Logan 1.6 about 400 thousand km, in practice the engine drove a little more . In 2010, the K7M 710 was replaced at the K7M 800, the motor was invented, pulled into the ecological norm of Euro-4, the capacity decreased to 83 hp, there was no constructive change. The minuses at K7M are the same as the engine K7J 1.4, high fuel consumption, often at idle begin to float the turnover, constantly (once in 20-30 thousand km) need to be adjusted valve, hydrocompensators as it was not so and no, the thrift The belt, when the belt is climbing, Logan 1.6 is a valve oppression, so once in 60 thousand km change the belt. All the same leaks of the crankshaft. Motor noisy, there are vibrations. On the device of the engine Renault Logan 1.6 and where the engine number is located, the information is set out in the article "Motor K7J", which, except for the volume and related changes, does not have other changes. There are also described all the malfunctions and the causes of their occurrence. Speaking about what engine on Renault Logan is better than 1.4 or 1.6 8 valves, take 1.6 ... The engine is the same, but a slightly disconnector is completely weak. Also, on the basis of K7M, the K4M engine with 16 valve GBC and other significant innovations was created, the power of such a motor is significantly higher and in the case of a choice (for example Logan, Sandero), always take it, you will not regret.Engine tuning Renault Logan K7M 1.6
Chip Tuning Engine Renault Logan Logan K7M 800 engine can be removed by the catalyst, return its initial power of 86 hp, put the exhaust and flash the sport with firmware, maybe a couple of horses and add, but nothing will change significantly, except for fuel consumption, now your motor will eat more.Renault Logan 1.6 8 8 Valves Repair (Video)
Applicability on cars
Budget models of Renault cars Logan 1.4 and Logan 1.6 over a nearly ten-year history of presence on Russian roads managed to conquer recognition of many thousands of motorists. The concept of the French manufacturer, who resolved in 1998 to create an inexpensive and practical passenger car, intended for emerging markets, received the most triumphant continuation and unexpected development. If in 2005 it all started at the small platform of the Autoframos enterprise in Moscow with a "screwdriver" assembly of several thousand cars per month, then today the Volga car plant builds his annual plans, relying on the whole "Loganovskaya" model paint: Renault Logan, Renault Sandero, Lada Largus. Sales of these three models in the country in 2014 exceeded 160 thousand pieces.
In a large extent, this popularity of these models of Renault ensured the use of proven and well-proven in other machines of the concern of the concern and well-established engines of internal combustion of the K7J 1.4 L and K7M 1.6 l series of internal combustion engines. The flagship line for Renault Logan is considered to be the 16V four-cylinder liquid cooling unit with the K4M index, the production of which, in addition to the Renault Espana parent company, also mastered the production sites of AvtoVAZ. These 16-dipal motors with decent technical characteristics still equip other Renault models (Sandero, Duster, Kangoo, Megane, Fluence), as well as Lada Largus and Nissan Almera G11.
Features of the design and DVS specification
Engine design K7J (manufacturer Automobile Dacia, Romania) 1.4 l / 75 hp It is inherited from the rather old Motors of the Renault 1980s corporation (EXJ series) and therefore looks somewhat archaic: here and the unusual chain drive of the oil pump used on units with the lower arrangement of the camshafts, and the ancient rims of timidation. The remaining engine solutions 1.4 are standard and no different from other four-stroke 4-cylinder single SOHC Type Motors: Round vertical cylinder location, 2 valves per cylinder, drive Timing from a toothed belt, Liquid cooling and combined lubricant system (for the most loaded DVS parts. Lubricant Under pressure, to all other things - simple splashing). K7J is more than 400 thousand km of mileage. Motor 1.4 provides a car the following dynamics: the maximum speed is 162 km / h, the hundred is dialing in 13 seconds.
Engine Renault Logan K7M 710 and its successor K7M 800 (production All the same Automobile Dacia) 1.6 l and 86 hp (K7M 800 - 82 hp) according to the design almost completely coincide with K7J, also have liquid cooling, but they have an increased piston increased by 10.5 mm, obtained by changing the height of the block. Other clutch and flywheel (larger diameter) are also used, and the gearbox crankcase has minor modified changes. The K7M resource also exceeds 400 thousand km in running. Dynamic motor characteristics: speed at a maximum of 172 km / h, 100 km / h - for 11.9 seconds, unlike 1.4.
The greatest differences in the design and characteristics are observed at the engine K4M, despite the fact that this internal engine is 1.6 liters and 102 hp It is also the next development of the K7M series. Absolutely new 16-valve cylinder head with two lightweight camshafts and a new piston system. Here, finally, it is eliminated by the need for constant adjustment of the DVS valves through sufficiently short runs, is eliminated by the simple use of well-known hydrocomathers. Motor speeds up cars up to 100 km / h in 10.5 seconds, reaching a maximum of 180 km - quite good characteristics. There are no frank weak points in this unit: the necessary changes are made to the system in terms of pumps and thermostat, the ignition module was completed.
Advantages and disadvantages of power units
Significant experience of operating car Reno with all three types of liquid cooling engines allows you to make a rather objective picture of their strengths and weaknesses, and two models of K7J and K7M are almost identical to these characteristics, and only the K4M engine has significant differences due to more modern technological solutions, And what better, solve already buyers.
Advantages of K7J and K7M:
- low cost and simplicity of engines;
- reliability: confirmed motor resource is more than 400 thousand km;
- versatility and maintainability;
- simplicity of maintenance;
- high torque;
- good "elasticity" of engines, equal to 1.83.
Disadvantages of K7J and K7M:
- relatively high fuel consumption;
- the instability of revolutions when working at idle;
- the absence in the design of hydrocomathers, as a result, the need for constant valve adjustments (after 20-30 thousand km);
- "Bend" valves with a sudden breakdown of the timing belt;
- increased "fluidity" crankshaft salts;
- weak reliability of the elements of the cooling system;
- noise and tendency to vibrations.
The advantages of the K7M model in front of the K7J can only be attributed to a 12% maximum power and at a 11% maximum torque. But for these advantages of KHS 1.6 l pays and increased by 4.5% appetite, so what is better, the question is controversial.
Advantages of K4M:
- reliability, practical resource exceeds 400 thousand kilometers;
- compliance with Euro-4 environmental standards;
- increased power (102 hp);
- low noise and vibration resistance;
- more modern and reliable cooling system.
Compared to 8-valve engines, K4M 16V works much quieter, not prone to vibrations and has the same resource, but significantly high power and torque.
Motor disadvantages K4M:
- expensive spare parts;
- "Bend" valves during belt breakdown;
- the weak "elasticity" of the engine equal to 1.53, as a result, problems with the acceleration of the car during overtakers.
Thus, a detailed analysis of the technical characteristics of all three DVS samples, as well as the practical experience of operating Renault Logan with these power plants makes it possible to determine which motor is better. The more powerful ICC 1.6 l with liquid cooling is still somewhat preferable to its "older brother" 1.4 liters. Power 75 hp It is simply not enough for a comfortable control of a loaded car either on a country track, nor in short "mining" in the city. And in the 16V dispute with 8V, the first sample acts as an unconditional leader. The only characteristic on which 16V loses to its opponent - "Elasticity". For the rest of the characteristics 16V is better better. The engine V16 with liquid cooling of the Renault corporation is simply much more modern and gives more opportunities to the driver.
Renault K7M 1.6 8V engine is used for installation on Renault Logan 1.6 8V (Renault Logan), Renault Sandero 1.6 8V (Renault Sandero), Renault Clio 1.6 8V (Renault Clio), Renault Simbol 1.6 (Renault Symbol).
Features. The RENAULT K7M 1.6 engine is not constructively different from, all differences in an increased to 1.6 liters of volume. The increase in the volume was achieved due to an increase in the radius of the crankshaft crank shaft (the remaining dimensions coincide), the piston move as a result increased from 70 mm to 80.5 mm. The height of the cylinder block increased, but all its geometric parameters are identical to K7J. On the Renault K7M and K7j engine, the same head of the cylinder block and connecting rods are set. Engine resource - 400 thousand km.
On the basis of the engine K7M, a motor with 16 valve cylinder head was created. This engine has more progressive characteristics and technologies.

Service
Replacing the oil engine Renault K7M 1.6. Replacing oil on Renault Logan cars, Sandero, Klio, Simbol with Renault K7M 1.6 engine is needed in 15000. km or the year of operation. With intensive engine wear modes (riding in urban traffic jams, work in a taxi, etc.) It is desirable to change the oil every 7-8 thousand km.
What oil pour into the engine: Type 5W-40, 5W-30, approved by Renault Easple ELF Excellium 5W40 from Plant.
How much oil pour: When replacing the filter, 3.4 liters of oil requires, without replacing the oil filter - 3.1 liters.
Original engine oil filter: 7700274177 or 8200768913 (both filters are interchangeable).
Replacing belt timber It is necessary every 60 thousand km. It is not necessary to postpone this procedure, when cutting the timing belt, the valve is oppressed. Replacing the timing belt can be combined with valve adjustment (hydrocompensators on Renault 1.6 8V are absent).
Air filter It is replaced once every 30 thousand km of run or 2 years of operation. In conditions of increased dusting, it is recommended to replace the air filter more often.
