1.5 DCI is a diesel four-cylinder engine with a turbocharger. Motor volume - 1.5 liters, and power, depending on the modification may vary from 64 to 110 horse power. Engine index - K9K. Released since 2001 and during this time some changes have undergone.

It is worth noting that this is one of the most popular turbo diesel engines created by the Renault-Nissan Alliance. This DVS is most popular in Europe, so on secondary market We can often see Urgent Renault and Nissans with such an engine. By the way, this unit is set for several more Mercedes.

From the obvious advantages of the motor - good thrust on the bottoms, relative economy of fuel. Of the minuses - poor susceptibility to the quality of diesel fuel, especially the Russian and maintenance requirements.

Indeed, that this DVS will serve for a long time and regularly needs to be followed. And this is changed motor oil Every 10,000 km of run or even earlier, while changing the timing belt - every 60,000 km and of course not overheating.

In responses, you can often find the following problems:

1) exit from building TNVD. Therefore, it is not recommended to acquire a version with fuel system Dephi, which is very demanding about the quality of fuel, and if you fill down poorly, it will die quickly. Recommended to take with Siemens (Continental). Delphi go on versions with a small amount of horsepower. Before buying, specify this moment.

Still with the Siemens system usually go models with a 6-speed mechanical box Transmissions. Engines with 5-mortar usually from Delphi.

2) failure of the turbine. This occurs most often due to improper operation. As we know, the turbodiesel cannot be immediately jammed after the stop, and you need to give it a little work, for this there is a configured autorun system in alarms.

4) Turning rod inserts. It happens if you do not change the oil during and lengthen the intervals of the replacement. Change every 10,000 km and such a problem should not arise.

As a result, I will say that before buying a car with an engine 1.5 DCI, it is necessary to carefully check not only the body, suspension, legal purityBut the engine itself, how it works, his mistakes scan, learn how often the oil changed, whether there were problems and so on. Often there are 5-7 year old megans with a mileage of 60-80 thousand, this, unfortunately, not always truth, mileage could twist. You can check it from the dealer, unless of course the mileage was not deleted from the car.

Purchasing a car with DCI should be regularly changed oil, filters, hinged equipment - In general, everything that will be needed, and choose a refueling, where you pour a really high-quality dielary.

And it's not necessary to say that this DVS is bad or good, since each instance has its own history and care, if we talk about used options.

For reference: It is installed on Renault Megan, Klio, Scenic, Dasia, Duster, Nissan Cascai, Tiid and other models.

With 1.5 liters, diesel remains the most popular and accessible among the CROWSERS domestic market. Such technical characteristics as a large torque of up to 240 nm (which gives a powerful thrust on 1750 revolutions), efficiency, smoothness and reliability makes the engine ideal for operation in any conditions, whether it is a city or off-road. After updating and restyling, diesel indicators have become even more deserved.

Diesel Models K9K 1.5 DCI French autoconecern Renault sets almost 12 of its Renault models. This diesel unit has shown himself with reliable, hardy, economical, for which he deserved universal popularity.

Instead of the chain in the Duster diesel engine, the timing belt is used. Durability is about 60 thousand km, it is after this figure that the manufacturer recommends changing the belt. Diesel K9K 1.5 DCI has 4 cylinders, each of which is equipped with only 2 valves, which in the end is 8 valves for the entire engine.

Disel for Dustea is equipped with the latest Cypt. COMMON RAIL.which reduces fuel consumption, the exhaustion consumption is only 5 liters on the track and 5.9-6 liters in the urban cycle. Naturally, such an engine becomes demanding of the quality of the fuel. With such advantages diesel engine SUV inferior to gasoline versions dynamic characteristics. Buying a diesel Renault Duster need to remember that it is necessary to refuel only with high-quality diesel fuel, otherwise the injectors and repair problems are inevitably. That is why many fearing such problems choose models with gasoline engines, despite their voraciousness.

Renault Megan 1 is a compact family car, serially entered the conveyor in 1996. Three versions were provided to the buyer to choose from: sedan, hatchback and wagon. The engine ruler included several gasoline and diesel options that differed dynamic and technical characteristics. The fact that Megan is with a diesel engine and how carefree is possession of such a car, read this article.

Specifications

When Renault Megan's first generation only gave the start of the production release, the car was positioned as compact and easy a carWhich at high efficiency was able to transport a significant amount of baggage. That is why, in places, the numbers are really amazed.

The length of a five-seater four or five-door Renault Megan with Diesel varies from 3931 to 4440mm, the largest length went to the universal. Despite the fact that in the photo this car looks quite large, with confidence it can be argued that Renault Megan can be attributed to the class of compact.

Width for all three versions, including hatchback and wagon, 1700mm. Such parameters created this car some popularity, because at a wheelbase of 2580mm, Renault Megane is able to overcome quite cool turns and make maneuvers in truly close corners. Height varies from 1365 to 1420mm, which gives an extra opportunity to pass low arches and park in a low garage.

A separate word deserves the mass characteristic of Renault Megane. Despite the fact that even the reviews talk about this car, as a fairly spacious family transport, the weight of the car is able to hit even an expert. If you believe in passport data, Renault Megane's oven varies, depending on the engine and body type, from 1010 to 1275kg. At the same time, the maximum burden is able to take the universal Renault Megan. If you believe the reviews, the maximum total mass of passengers and baggage can reach without a small 600kg.

The suspension here is combined: a traditional MacPherson is installed on the front on Renault Megane, and a semi-independent mechanism is installed behind. This allowed the universal to transport an even greater amount of baggage. Front brakes disc, and rear - drums.

It's time to move to dynamic characteristics. Renault Megan with Diesel was produced only three variations. Three Motors of 1.5 liters and a capacity of 64, 95 or 100 horsepower are available for Renault Megane with Sedan Body, Wagon and Hatchback. All engines are in line, with a GBC under 4 cylinders and cross-arrangement in the subcontrol space.

The most low-power diesel 1.5 for Renault is capable of pumping up to 118 newton-meters of torque. Wherein maximum speedwhich is capable of developing Renault Megan, is only 160 kilometers per hour. The consumption is quite high for the motor such configuration: 5.3 liters on the highway and as many as 8.6 in the city - almost a gasoline indicator. Overclocking up to 100 km / h occurs only for 16.5 seconds, and the stroke step depending on the ride mode will vary from 750 to 1100 km.

"Urban" from a line of 1.5-liter diesel engines has a power of 95 horsepower.

Structurally, the engine has one significant difference. There is an intercooler and turbocharging. Such an additive allowed with an equal volume to significantly add in terms of power and torque Renault Megane.

For example, the maximum torque of this engine is reached already at 4000 revolutions per minute and is 176 Newton meters. Fuel consumption in the city reaches without a small 8 liters per 100 kilometers of the way, and on the track this indicator is reduced to 6. Acceleration up to hundreds occurs in 12.3 seconds, and the maximum speed reaches 180 km / h.

The most powerful 1.5-liter motor in the ruler has enhanced GBC and is able to develop the power of 100 horsepower. Torque is truly striking here. It is equal to 200 Newton meters. Acceleration up to 100 kilometers per hour occurs for the same 12.3 seconds, but the maximum speed here reaches 183 kilometers per hour. Diesel consumption pleases. If the car appetite is limited only to 4.4 liters, then in the city 1.5-liter unit will not consume more than 6.8.

Impressions of drivers

Reviews speak many. In the case of Renault Megan with the installed diesel, the reviews allowed to reveal everything possible problems And the disadvantages of such motors, including unreliable cylinder head and oil leakage, find the most optimal way to solve them.

The greatest number of complaints goes to work GBC engine 1.5, which, with a significant run, either gives a crack, or requires the replacement of the gasket.

Evgeny. Owning experience 4 years.

I have become the third owner of the wagon with a 1.5-liter diesel engine. Mileage, of course, solid, so it would be surprising not to encounter repair GBC.. For such an operation in the service, I was voiced by a considerable amount, so I collected the will into the fist and repaired the GBC himself.

No less problems, judging by the reviews, it raises the gasket of the GBC Renault Megane, which in non-compliance with the regulations quickly makes itself felt.

Vladimir. Owning experience - 2 years.

I have a wagon with a 1.5-liter engine. GLP gasket I gave yourself to know almost immediately: I went and changed. Otherwise, in addition to a minor zhora oil, I did not find problems.

Another nuance Renault Megane is a hindered engine launch in winter, which is characteristic of motors such a configuration.

Irina. Owning experience - 3 years.

My wagon with a 1.5 liter MT engine was never failed until frosts hit. The launch became very difficult: I had to constantly use additives. Bought new battery - helped, but the problem did not completely disappear.

Summary

Renault Megane with a turbocharged or atmospheric diesel engine is a reliable and economical car. Knowing certain nuances of this engine, you can avoid most problems in possession and ensure yourself trouble-free and durable cars, which will serve not one year.

Small turboodiesels have already managed to conquer the hearts of millions of motorists. Their main advantages - affordable price and high efficiency, comparable with larger brethren. One of the first automakers to start the release of small diesel engines was Renault, which developed with Nissan's cooperation very popular 1.5 DCI. Today, many cars are equipped with this engine.

The smallest of the ruler diesel engines Renault - force aggregate With the designation K9K debuted in the market in 2001. The eight-flaped four-cylinder engine with turbocharged and fuel supply type "Common Rail" was offered in several versions - with a capacity of 64 to 110 hp. The main differences between modifications are to equip the injectors, turbocharger, flywheel, etc. The advantages of the aggregate include: relatively high power and low fuel consumption - on average about 6 liters per 100 km. 1.5 DCI Engine is widely used in Renault, Dacia and Nissan cars. In the period from 2003 to 2010, the turbodiesel was installed on a small SUV Suzuki Jimny., After the start of cooperation, Renault with Mercedes - and in the new models of A-Class, and in the Citan van (the same Renault Kangoo is only with a characteristic star on the radiator grille).

Characteristic problems and malfunctions

The list of problems pursuing 1.5 DCI is quite large. One of the most serious and most common - malfunction of the system. As a rule, this is due to the use of low-quality fuel, which is not a french diesel. This is especially true of engines with Delphi nozzles, which may not withstand on poor diesel fuel and 10,000 km. The cost of one nozzle is about 8-12 thousand rubles. In modifications with a simple system and "normal" nozzles, you can save significantly by trying to restore their performance. In the case of piezoelectric nozzles, the only way out is only replacement.

The turbocharger on some copies can deliver trouble after 60 thousand km. Turbocharger used two types - fixed or variable geometry.

Sometimes there are cases of turning into the liners and the loogier of the pistons - due to poorly working nozzles. In addition, it is necessary to deal with habitual for diesel motors malfunctions of the EGR gas recycling recycling valve. In more powerful versions there are disadvantages with a two-headed flywheel.

Other typical problem For modern diesel - dairy filterwhich may require extensive costs. The cost of the new is better and not to ask, but prays to the troubles associated with it, bypass you. Sometimes the troubles are presented with electronics of engine operation: especially vulnerable puzzle pressure and shaft position sensors.

As can be seen from the review, potential problems with 1.5 DCI engine are quite a lot. However, the overwhelming majority of them are associated with improper operation. To avoid further unnecessary and high costs, owners diesel cars It is worth compensating for gaps in their knowledge, due to the exploitation of only hopeless gasoline engines.

Conclusion

And yet, some consider 1.5 DCI rather risky choice. At the same time, most of the owners of the machines with these Turbodiesel are very satisfied with their acquisition and want to see 1.5 DCI under the hood and in the future. Before buying such a car, it is still worth estimated - how many kilometers per year have to get out. If the mileage is small, then more profitable will be a car with gasoline engine. Despite some flaws, in reliability 1.5 DCI is not inferior to most famous diesel engines, more eminent manufacturers.

Renault K9K engine

Engine characteristics K9K.

Reliability, problems and repair engine K9K

This turbodiesel was first shown in 2001 on car Renault. CLIO 1.5 DCI, then began to put it in everything that is moving slightly. He replaced 1.9 liter total F8Q. The cylinder block K9K cast iron, the crankshaft is installed inside it with a piston stroke 80.5 mm, the length of the connecting rods is 133.75 mm, the diameter of the pistons is 76 mm, and their compression height is 56 mm. In sum, we obtain almost 1.5 liters of working volume, to be accurate, then 1.46 liters.

Aluminum Cylinder Cylinder head is monomial and has 2 valves per cylinder.The diameter of the inlet valves is 33.5 mm, the exhaust valves - 29 mm, and the thickness of the valve rod 6 mm.
Adjusting valves on K9K is required every 50 thousand km. Clauses of valves for cold: inlet 0.2 mm, Issue 0.4 mm.
The timing belt is applied in the GDM system, its service life of 90 thousand km. Since 2004, the interval has increased to 120 thousand km, and from 2008 to 160 thousand km.

The weakest version of this K9K was equipped with a BorgWarner KP35 turbine, pressing pressure 1 bar. Here is the Injection of Common Rail from Delphi. Power of this engine 65 hp At 4000 rpm, torque is 160 nm at 2000 rpm.
A similar version with an intercooler and pressurized pressure 1.2 Bar had a capacity of 80 hp. At 4000 rpm and torque of 185 nm at 2000 rpm.
The most powerful modification of the diesel engine was equipped with a BorgWarner BV39 turbine with a variable geometry, which inflates 1.25 bar, and Common Rail here from Continental / Siemens, the pressure in the Ramp was increased from 1400 to 1600 bar. Such a motor develops 100 hp at 4000 rpm, and torque 200 nm at 1900 rpm.

In 2004, the production of second generation of Diesel K9K began, which moved to the Euro-4 standard. The compression ratio decreased to 15.9, injection was finalized and graduation system. Also raised the service life of the timing belt, and now it is necessary to change it once every 120 thousand km. The term for replacing the oil is increased to 20 thousand km.
The most negligible version has a capacity of 65 hp. At 4000 rpm, torque is 160 nm at 1750 rpm. Power of the same motor with an intercooler 85 hp at 3750 rpm, and torque 200 nm at 2000 rpm. Top Renault K9K develops 105 hp At 3750 rpm, torque is 240 nm at 1750 rpm.

The third generation of the motor was published in 2008 and began to comply with the ecological standards of Euro-5. The compression ratio was reduced to 15.2, the engineers were finalized by the EGR system, put the sump filter, increased the service life of the timing belt to 160 thousand km, and the oil replacement interval stretched to 30 thousand km.
The version without intercooler received injection from Bosch and develops 75 hp. At 4000 rpm, torque is 160 nm at 1750-2500 rpm. The same, but with an intercooler 90 hp At 4000 rpm, torque 200 nm at 1750-2500 rpm.
The most powerful model has a capacity of 110 hp At 4000 rpm, torque is 240 nm at 1750-2750 rpm.

The fourth version of K9K was shown in 2012 and it is sharpened under the Euro-6 standard. The degree of compression has slightly increased (up to 15.5), changed EGR, the sump filter, oil pump, piezo-forming, added the start-stop system. Characteristics of weak version Such: Power 75 hp At 4000 rpm, torque 200 nm at 1750-2500 rpm. Analogue with the intercooler developed 90 hp at 4000 rpm, torque 220 nm at 1750-2500 rpm.
The top model was replaced with a turbine on BorgWarner BV38 with a variable geometry, which allows to get 110 hp At 4000 rpm and torque 260 nm at 1750-2750 rpm. Such an engine is known as Mercedes OM607.

Since 2011, the engine K9K 1.5 DCI is replaced with a newer 1.6-liter Diesel R9M.

Problems and malfunctions of diesel engines Renault K9K

1. Main disease Diesels K9K is skeeping inserts. Due to the peculiarities of their design, due to the too large interval between oil changes, due to the use of low-quality oil, after 100-150 thousand km, there is a very high risk of grinding inserts. It is better not to wait for this moment, immediately check and replace them after 100 thousand km or after buying a car. We are also a good (not fake) oil and change it at least once every 10 thousand km.
2. Many complaints about engines with Common Rail from Delphi, in which, due to poor fuel, quickly fails and pulls up the nozzles. It is recommended to change here fuel filter Once at 8-10 thousand km on the original and pour only good fuel. There is no such problem with Siemens with Common Rail from Siemens, but this does not mean that you can merge diesel fuel from the nearest tractor. Here you need to change filters every 10 thousand km.

The rest of the engine is normal and has good reliability. The term of the turbine is high and it may be enough for the entire service life of the engine, but the turbine ahead of time can kill particles from the wear of the liners that have fallen into the oil.
Also worth it once a year to clean the EGR valve from Nagara.
If pouring is not bad fuel, good oil, on time to change it, timely and efficiently serviced, the engine resource K9K easily exceeds 300 thousand km. Often, these diesel engines die on runs about 200 thousand km and causes can be different: poor service twisted mileage, or both immediately.

Engine tuning K9K.

Chip tuning

Want to add some power? Drive to tuning company and pour more aggressive firmware, it will turn your 75 hp. or 90 forces in 115 hp, and torque will exceed 250 nm. Motors with a capacity of 110 hp Senched in 130-135 hp, torque exceeds 300 nm. This refers to the 4th generation motors, produced after 2012.
The last 3rd version (2008-2012) has the indicators a little worse. The most powerful modification of 110 hp Sold in 130 hp, torque 300 nm, and a model by 75 hp and 90 hp You can dig up to 110 hp And torque will increase to 240+ nm.
The older 2nd generation (2004-2008) has the same indicators, except that the weakest model has a limit of 90 hp. and moment in 200 nm.
The very first k9k, issued in the period 2001-2004, has almost the same potential. The most rude modification is tuning up to 85 hp, the moment is 200 nm.
