Renault Duster 2 liter timing device worries quite a lot of potential buyers, since the further operation of the crossover depends on the design features of this engine. We will look at the technical characteristics of the Renault Duster with a 2-liter engine a little lower, but for now let’s talk about the mechanical part.

The in-line 4-cylinder 16-valve Renault 2-liter engine has the factory index F4R. This engine model and its modifications can be found on many other Renault models. The unit is assembled at the Renault engine plant in Spain. Let’s say right away that before the Duster restyling, this naturally aspirated engine produced only 135 hp. The new version of the compact crossover began to install a more advanced modification of the F4R with a variable valve timing system, this made it possible to meet Euro 5 standards and increase power to 143 hp.

The engine design is not new; its roots go back to the distant 80s. The design is based on a cast-iron cylinder block, a timing belt drive, and two camshafts. The engine has hydraulic compensators, so there is no need to manually adjust the valves. True, the 2-liter Duster engine has one problem: if the belt breaks, the valve bends. If you monitor this and carry out qualified maintenance in a timely manner, then the service life of the engine can easily exceed 400,000 kilometers.

Typical for DOHC engines. A feature of replacing the timing belt can be considered the absence of installation marks. Before removing the belt, it is necessary to firmly fix the camshafts and crankshaft relative to each other. To block the crankshaft, there is a special technological hole in the cylinder block into which a locking bolt is screwed. To block the camshafts on the opposite side of the valve cover, under two technological plugs you will see the ends of the camshafts with special slots into which you need to insert a common plate, which will prevent the camshafts from turning. To loosen and tension the timing belt, you will need a tensioner, which will need to be used when tensioning the pulley. Next is a schematic photo of the timing diagram of Duster 2.0

Official Renault video on the importance of periodically replacing the timing belt. For Duster 2.0 this period is 60 thousand kilometers.

Technical characteristics of the updated Duster 2.0 engine (143 hp)

• Working volume – 1998 cm3
• Number of cylinders/valves – 4/16
• Cylinder diameter – 82.7 mm
• Piston stroke – 93 mm
• Power hp – 143 at 5750 rpm
• Power kW – 105 at 5750 rpm
• Torque – 195 Nm at 4000 rpm
• Compression ratio – 11.1
• Timing Drive - Belt
• Maximum speed 6-speed manual transmission – 180 km/h
• Acceleration to the first hundred 6-speed manual transmission – 10.3 seconds
• Fuel consumption in the city 6 manual transmission - 10.1 liters
• Fuel consumption in the combined cycle 6-speed manual transmission – 7.8 liters
• Fuel consumption on the highway 6 manual transmission - 6.5 liters

It is worth noting that the pre-restyling Duster 2.0 had a modification with front-wheel drive and an automatic transmission, but after the update, the crossover with a 2-liter engine is sold only with all-wheel drive and the same manual and automatic transmissions.

The Renault Duster crossover is equipped with one of two petrol engines or a diesel one. The most powerful of them are the 143 horsepower 2.0 power units with the factory designation F4R. They are manufactured at the Renault plant in Spain and, according to reviews, significantly surpass their predecessors in performance.

The new F4R is manufactured according to the classical design and belongs to the class of 4-cylinder sixteen valve naturally aspirated gasoline engines. Unlike many modern power units, which install aluminum cylinder blocks, Renault has not changed traditions and produces cast iron blocks. This significantly increases the service life of the Renault Duster engine and makes the cylinder block repairable. The manufacturer does not indicate the service life of the unit in the documentation, but it is assumed that with proper operation, it exceeds a mileage of 300,000 kilometers.

Fuel supply system - distributed injection

Fuel is supplied through a gasoline filter with a service life of 120 thousand kilometers. Gasoline enters the combustion chamber under pressure through a separate nozzle for each cylinder. The combustible mixture is prepared before it is supplied to the inlet valve. Therefore, the mixture is more homogeneous and burns more efficiently. As a result, the power of the 2.0 Renault engine increases and the emissions of toxic substances are reduced.

Duster's power system is completely electronically controlled. The fuel supply period is calculated for each injector individually.

Gas distribution system

The new Renault Duster 2.0-liter power unit is equipped with a variable valve timing system.

The design of the Renault Duster VVT system allows you to adjust:

• valve closing and opening moments;
• valve lift height;
• turning the camshaft.

Turning the camshaft adjusts the timing, shifting the opening and closing of the valves with optimal timing. The camshaft phase is controlled by a fluid coupling (phase shifter), which is controlled by an electronic unit. Renault phase adjustment ensures optimal operating modes of the unit for:

• maximum speed;
• maximum load;
• Idling.

The design of the phase distribution system of Duster 2.0 can significantly reduce fuel consumption and increase the power of the unit. Timing belt drive. Although they wrote a lot on the Internet that it is chain-linked.

Ignition system

Renault ignition is controlled by an ECU and consists of spark plugs and coils. Does not require adjustment or maintenance, but, according to reviews from Duster owners, ignition coils often fail.

Cylinder block

The Renault Duster block is made from high-strength cast iron alloy and includes:

• cooling jacket;
• cylinders;
• upper part of the crankcase;
• crankshaft bearings;
• beds for main bearings.

The Renault cylinder head is made of aluminum.

The crankshaft, driven by the piston system, transmits torque to the automatic transmission torque converter drive disk or flywheel.

F4R Specifications:

• cylinder capacity – 1998 cm3;
• bore x stroke – 82.7 mm x 93 mm;
• power – 143 l. With. at 5750 rpm;
• torque - 195 N/m at 3750 rpm;
• compression ratio – 11.05.

Reviews about the 2.0 Duster engine are contradictory, but if you compare it with its predecessor, the progress is obvious. The power increased by 8 horsepower, the traction and maximum speed of the Duster increased accordingly, despite the fact that fuel consumption remained virtually unchanged, and the environmental standard increased to EURO 5.

Car owners opinions

Georgy, driving experience 15 years

I chose Renault Duster for a long time, trying to get my bearings based on reviews. While I was thinking, a new Duster appeared after restyling. I signed up for a test drive at the salon because I wanted a 2.0 engine, but greed prompted me to take the 1.6. Wisdom won over greed, and I took a Renault Duster with a two-liter F4R. The test drive showed that seemingly identical Dusters are completely different in traction and dynamics. The fuel consumption of the more powerful Renault is not much more than that of its younger brother. On the highway 8 liters, in the city 12-13. I'm happy with the purchase. Cheap and cheerful.

Andrey, driving experience 9 years

No matter how many reviews I read about Renault Duster, everything is the same: good noise protection. These are all lies written by fans of city driving. Why buy a 143 horsepower engine if the noise reduction disappears on the highway at speeds above 110? And I want a fast and comfortable ride. The 2.0 Renault Duster engine is excellent and allows you to accelerate to 170 km/h with a reserve. In addition, it drives uphill through mud and snow like a tank. Of course, all-wheel drive helps the power unit overcome obstacles, but all the same, the frail engine would not go uphill.

Yuri, driving experience 7 years

Before purchasing the new Duster 2.0, I noticed a review that the phase shifter often fails in new engines. But I bought it. There were no problems with the car until approximately 24,000 km. But gradually a ringing sound began to be heard, like a diesel engine. Every day the sound grew stronger. Fuel consumption has also increased. I went to the officials. They told me to change the phase regulator, timing belt and rollers. Changed it. I got into the car, Duster, as if born again - silence. Gasoline consumption has decreased. This is good, but why did you fly out so early? At least 80,000 would pass.

Max, driving experience 4 years

I've been waiting for several months for Renault to release the new F4R 2.0. Traveled 40,000 kilometers. I'm happy with almost everything about the engine, except that it eats oil. Approximately every 2000 km I add 700 grams of oil. I went to the service station, they said that this is the norm for Renault Daster. May be so. Oil consumption does not increase. Otherwise, Renault didn’t notice any problems with the engine, if you don’t find fault with the little things. Maybe it’s just noisy at high speeds, but I usually don’t drive faster than 110 km/h.

The car has three power plants: a pair of gasoline and one diesel. Gasoline engines are represented by a 1.6-liter H4M unit (114 hp, 156 Nm) and a 2.0-liter F4R engine (143 hp, 195 Nm). The basic naturally aspirated 1.6-liter “four” is produced at the plant in Togliatti. The 1.5 dCi turbocharged diesel engine with the K9K index is installed on many cars of the Renault-Nissan alliance. In relation to the Duster, its output is 109 hp, and the maximum torque is 240 Nm (from 1750 rpm). All power units of the crossover comply with the requirements of the Euro-5 environmental standard and have an economical Eco mode.

The range of transmissions available for Renault Duster includes 5 and 6-speed manual transmissions, as well as a 4-speed automatic DP8. Only the 2.0-liter engine gets an automatic transmission; the other two engines are content with “mechanics”. Most Duster modifications are equipped with independent rear suspension and all-wheel drive. The only version with a torsion beam at the rear and a 4x2 drive scheme is the initial version with a 1.6 engine and a 5-speed manual transmission. In all-wheel drive versions, power is transmitted to the rear wheels using the GKN clutch, which is also used by the crossover. Once Lock mode is activated, it can remain locked at speeds of up to 80 km/h.

The trunk volume of the Renault Duster 4x4 is 408 liters (with the rear seat backs folded - 1570 liters). The spare wheel is hidden under the floor. Crossovers with front-wheel drive have a more spacious cargo compartment (475-1636 liters). The spare tire for such modifications is attached to the underbody.

Fuel consumption of gasoline versions of Duster varies from 7.4 to 8.7 liters. A diesel engine consumes an average of about 5.3 liters of diesel fuel.

F4R engine malfunctions and repairs

Engine Renault F4R 2.0 l. 135-138 hp (depending on the index), the latter became especially popular thanks to the popular Renault Duster SUV and the Megan family. There are a number of different modifications of the F4R, with various indices, their power varies within narrow limits, from 135 to 138 hp. The index shows the car for which this engine was intended (mounts) and the engine settings. Almost all parts of the F4R are interchangeable and the differences are mainly in the attachments. In addition to the usual variations, there are also sports ones - used on the Clio Sport with power from 169 hp. up to 200 hp Their differences: electronic throttle, different air filter, steel crankshaft (instead of cast iron), modified cylinder head, exhaust.
I would like to immediately put an end to the issue of a belt or chain on the Duster engine; the engine has a timing belt drive. F4R itself is not new enough, all its disadvantages are known and the causes of malfunctions are known. Let's look at the most popular faults of the F4R 2.0: the phase regulator, it fails once every 60-70 thousand km, this will be indicated by the sound of the engine reminiscent of a diesel engine, in addition, such a sound may indicate more serious problems (cracked cylinder head, burnt out piston, valve) , one way or another you need to measure the compression and proceed from that.
Ignition coils do not last long; when the F4R Duster engine fails, it begins to twitch, this is the main reason, besides it, the issue may be in the crankshaft position sensor (crankshaft position sensor) or in the spark plugs.
The throttle valve likes to get clogged and your Renault F4R does not start in the best way; after cleaning, the problem disappears as if by hand.
The rear crankshaft oil seal, likes to leak on engines with mileage over 100 thousand km, can be changed without problems.
The Duster engine speed fluctuates, this is a feature of the engine, it’s not scary. Speaking about the features, you need to note one more thing, the noise of the Renault Duster engine in the timing belt area, this is also not scary.

In addition to everything written above, the Duster F4R engine is characterized by increased oil consumption.
Despite everything, the motor is quite decent and will not cause any special problems during normal operation; the service life of the Duster engine is 250-300 thousand km before major repairs.

Choosing a car Duster/Megan, etc. look at the 2 liter engine, 1.6 K4M will not be enough.

Engine tuning Renault F4R 2.0 16V Duster\Megan

Chip tuning, firmware for Renault Duster F4R engine. Finalization

Exactly like 95% of other naturally aspirated engines, the firmware won’t do anything here, feel free to throw this idea out of your head. It will be much more effective to convert your 2 liter Renault Duster engine into a Clio RS engine, install camshafts from RS or tuning ones with a phase of about 280 + intake + direct-flow exhaust + flash and it will run at the level of 170 horsepower engine. For further modifications, you need to change the piston to forging, modify the cylinder head... cut the channels (yes, yes, like a real pelvis :)), modify the valve seats, remove sharp edges, grind the channels, install a lightweight flywheel, receiver... maybe you can get up to 200 hp. With. If you really want, you can install a 4th throttle intake on evil shafts, somehow configure it, but the cost of construction will be hellish, the ratio is $/hp. beyond comprehension.

Compressor and turbine for Renault F4R Duster/Fluence/Megan 2.0 liter

There are no ready-made compressor kits for F4R; you will have to buy a separate compressor with low pressure... 0.5 bar for a standard motor is the limit. We are looking for such a compressor, 360cc injectors, direct-flow exhaust, set it up online and about 200+ hp. can be inflated. Install a more efficient turbine on the F4R and inflate 300 hp without any problems. as on the Megane RS, it won’t work, the F4RT turbo engine from the F4R, in addition to the turbine, has a different reinforced block, pistons for a lower compression ratio, so you need to build a fast turbo engine initially on the F4RT.

Which is a cross between an SUV and a hatchback, has become popular in recent times. This is not surprising, given the low price of the car for an SUV. But many potential buyers are interested in the issue of fuel consumption per 100 km of the Renault Duster. Based on the official information in the passport and reviews of owners on forums, we can come to a certain conclusion.

Car engines

Renault Duster, which is produced for sale in Russia, can be equipped with three types of engines with different fuel supply systems and powers. The following engines are supplied to Russia:

1. Turbodiesel 1.5 liters with 109 horsepower. It has increased traction, torque is 240 Nm at 1750 rpm. There is also a new fuel injection system and turbocharger.
2. Gasoline engine with cylinders with a total volume of 1.6. Its power is 114 horsepower, there is also a chain drive and a variable gas distribution system.
3. Petrol engine with cylinder capacity of 2 liters. Its power is 143 hp. With. This engine has a special economy mode and variable gas distribution phases.

Quite naturally, the gasoline consumption of a Renault Duster will differ depending on the type of engine used.

Passport consumption and efficiency

The relatively new Renault Duster is equipped with fairly economical engines that fully meet the requirements of the international environmental standard EURO 5. The designers of these engines have used some innovative solutions, thanks to which not only the gasoline consumption of the Renault Duster has decreased, but also the car’s throttle response has improved.

The diesel engine is now equipped with a variable geometry turbocharger. This is done so that the cross section at the turbine inlet can change as the load on the engine itself increases. This means that under any load - large or small - the engine will operate in conditions close to ideal, and will not “eat” excess fuel at both high and low speeds. He always takes exactly as much fuel as he needs. Also, the diesel engines of this machine have a Common Rail injection system, which can supply fuel under controlled high pressure and, more importantly, variable torque depending on the number of engine revolutions.

All these innovations have made it possible to achieve significant fuel savings. Because of this, the Renault Duster’s fuel consumption per 100 km fits into the following figures:

1. In the city - 5.9 liters.
2. On the highway - 5 liters.
3. Mixed cycle - 5.3 liters.

For a diesel engine these are quite good figures.

Consumption of Renault Duster 1.6 with gasoline engines

1.6 liter engines have a variable valve timing system. According to the designers, this made it possible to reduce gasoline consumption. In addition, the car uses electro-hydraulic power steering, and this also plays a role. The fact is that the pressure in the amplifier is created not by the engine, but by a separate electric motor, which allows saving an extra liter per 100 kilometers. Fuel consumption of Renault Duster 1.6:

1. In urban conditions - 9.3 liters.
2. On the highway - 6.3 liters.
3. Mixed cycle - 7.6 liters.

Considering the engine size, it cannot be said that Renault specialists were able to create something unique in terms of fuel economy. The same old Opels produced in 2003 consume approximately the same amount of fuel with the same engine size. This applies not only to Opels, but also to cars of other brands. Therefore, 9.3 liters of gasoline in urban conditions with a 1.6 liter engine is normal, but not cool.

Fuel consumption of Renault Duster 2.0

The most powerful engine that can be used in this car is a 2-liter eco engine. The ecosystem in this engine reduces fuel consumption when there is no need for high power. In this case, this mode is turned on manually by pressing a button, and is turned off by default.

Fuel consumption of Renault Duster per 100 km with a 2.0 petrol engine:

1. In the city - 10.1 liters.
2. On the highway - 6.5 liters.
3. Mixed - 7.8 liters.

When the mode is turned on, savings reach 10% of total consumption. This means that in Eco mode, city consumption can be “caught up” to 9 liters per hundred, but engine power may be slightly reduced.

What affects efficiency?

Note that the real consumption of the Renault Duster is somewhat different. After all, the figures indicated above are valid only for an ideal car under ideal operating conditions. But in reality, the gluttony of the Renault Duster car is determined by many factors:

1. Technical condition of the engine and the machine as a whole. For example, if the body is crooked, fuel consumption increases significantly.
2. Technical condition of the chassis and transmission.
3. Equipment.
4. Transmission type.
5. Number of drives, etc.

An important role is played by the driver’s ability to change gears on time and not over-throttle. Therefore, no one can say the exact fuel consumption per 100 km of the Renault Duster. It will always be individual for each owner of this car.

We also learn from driver reviews that some breakdowns can greatly increase fuel consumption. Sometimes gasoline consumption increases several times. Even tire pressure can increase the load on the engine, and as a result, fuel consumption will increase.

Powertrain and Economy

The transmission and equipment of the car play an important role. Renault Duster is equipped with 4x4 and 2x4 manual transmissions. There is also a 4x4 automatic transmission. Each of them will create its own unique load on the engine. Therefore, the fuel consumption of a Renault Duster 4x4 will differ from that of a 4x2 vehicle. The driver's driving style also determines whether fuel consumption will be increased or decreased.

The same can be said about the drive. On big climbs, all-wheel drive pays off and even saves gas. When towing with front or rear wheel drive, gasoline is consumed much faster and a lot. In this regard, an all-wheel drive car is better.

Real fuel consumption of Renault Duster

Driver tests have shown that the rated gas and diesel consumption of this car is radically different from the real one. In principle, this should not surprise anyone - this happens more often than we would like.

If you try and keep the speed and speed stable, the diesel consumption on the highway will be approximately 6-6.2 liters per 100 kilometers. But usually this doesn’t happen, because it’s impossible to find a perfectly flat route. You always have to accelerate, slow down and go around something. Therefore, consumption of 6.3 liters of gasoline per 100 kilometers can be considered a normal result.

If you want all-wheel drive, there is an option with a 1.6-liter gasoline engine. This model consumes 9.6 liters in the city, and this practically corresponds to what the manufacturer writes in the passport. Of course, with the air conditioning on, consumption will increase to 10.2 liters per 100 km.

If you believe the reviews of the owners, then fully loading the car with passengers can increase the consumption in the city to almost 11-13 liters. However, on the highway the consumption will be 7 liters per 100 km, which is also an acceptable result.

The actual fuel consumption of a Renault Duster with a 2-liter engine and all-wheel drive in the city is 11.6 liters per 100 km. If you go a little higher in this article, you will see that the passport value is -10.1 liters. And if you turn on the air conditioner in parallel, the consumption will increase by another 1 liter. On the highway, a car with this configuration consumes its fair 8 liters. You can even achieve seven liters per 100 km, but this is with the Eco mode turned on, which, as you remember, saves on average 10% of gasoline.

Consumption in traffic jams

But getting stuck in traffic jams with this car is extremely undesirable. After all, when driving at a speed of 10-20 kilometers per hour, the real consumption of the Renault Duster can be about 21 liters per hundred. Some owners share terrible photos of the on-board computer, which shows a consumption of 45 liters per hundred, but this is when driving in a traffic jam.

How to drive economically?

If you are the owner of a Renault Duster car with an engine that “eats” gasoline, then you need to adhere to the following rules:

1. When accelerating, increase the torque to 4000.
2. After accelerating in last gear, move with the arrow on the tachometer at 2000 rpm.
3. When driving around the city, try to keep the tachometer needle within 2000 rpm in 2nd-4th gears.

If you have a diesel engine, then the situation will be slightly different. Typically, the optimal torque for a diesel engine is 2000 in fifth gear and a speed of 100-110 km/h. However, for Renault Duster this mode is reduced. All because of the diesel engine that is used here. Here, diesel fuel consumption is regulated by a special injection system and an unusual turbocharger with variable geometry. Owners of these cars write on forums that their car is actually economical under any operating conditions. But you can fully appreciate the efficiency of a diesel engine only with the correct driving style. And this is true for all cars, not just the Duster.

Opinions

Many reviews can be found on thematic forums. They often write about buying Renault Dusters with diesel engines because of the obvious savings on fuel. In the city, the car consumes 6.5 liters of diesel fuel per 100 km, but only if the driving style is correct. As a result, savings compared to gasoline are about 200 rubles per 100 kilometers.

But owners of gasoline engines (1.6 l) sometimes complain. Consumption in the city is 10 liters, this figure grows in traffic jams. Because of this, you have to refuel your car more often than you would like. Therefore, for megalopolises and busy cities, where traffic jams are a common occurrence, a Renault Duster with a gasoline engine is unlikely to be suitable. The ideal option is a diesel engine with low fuel consumption.

Overall, this car is worth the money that sellers are asking for it. Of course, it cannot be called economical, but Renault-Duster can give some other analogues for the same money a head start in terms of efficiency.
