Renault 350 engine fuel what s going on

The driving habits are different, the road conditions are different, the traffic jam, the load, the oil, the hot and cold air, whether the run-in period of the old car is different, the fuel consumption is not the same, the general comprehensive fuel consumption is about 8-10. How many oils means how many liters of oil per 100 kilometers. is a colloquial idiom.

Vehicle fuel consumption is generally calculated based on fuel consumption per 100 kilometers, such as 10L fuel consumption per 100 kilometers, which means that the vehicle needs 10L gasoline for 100 kilometers. It is recommended to calculate it yourself according to the following method:1

According to the trip computer on the car. Generally, better cars have a trip computer with real-time fuel consumption and average fuel consumption. When you want to calculate fuel consumption, empty the data inside, and the average fuel consumption read is more accurate.

Some cars do not support the driving computer or the computer does not support clearing data, so the second method can only be used. Some people also say that the data calculated by the driving computer is inaccurate. But the amount of fuel is controlled by the car, and the car can also know the number of kilometers, so why is the data inaccurate?

So I think the data calculated by the driving computer should still be reliable. 2.Each of the following steps is required to be strictly implemented, otherwise the calculated fuel consumption may not be accurate.

When refueling first, add until you jump the gun, don't refuel at this time, and record the kilometers at this time. After running for a period of time, when you refuel, you still add until you jump the gun, and you don't refuel again. Record the amount of fuel and calculate the number of kilometers since the last run, and divide the two.

Why is this method more accurate to calculate fuel consumption, because the size of the fuel tank of the car is fixed, and the fuel gun is also standard, so when it is added to the jump gun, basically the amount of fuel in the fuel tank is fixed, so we can use this method to ensure the accuracy of fuel consumption calculation to the greatest extent.

The engine is a diesel engine, and the factors of high fuel consumption of diesel engine are: 1. Insufficient diesel combustion. The main reason for the insufficient combustion of diesel fuel is that the compression ratio is not enough, as the saying goes, air leakage.

The main causes of air leakage are the wear of cylinder liners, pistons, and piston rings, and poor sealing, and then valve leakage, valve or valve wear. 2. The second reason for insufficient combustion is that diesel atomization is not good. The main reason for poor atomization is that the nozzle, plunger, and outlet valve are aging, or the nozzle is poorly adjusted.

3. The oil supply time is incorrect. 4. The air filter is clogged and the air intake is not smooth. Intake and exhaust valve clearances are incorrect.

5. The oil lubrication system is faulty and the lubrication is not good.

Summary. First of all, the reasons and solutions for the high fuel consumption of Renault Koleos are as follows: 1. The quality of the fuel added is too low

When the quality of the fuel added to the car is too low, the fuel and gas mixture can not be fully burned in the engine, which will cause part of the fuel waste, and then affect the fuel consumption of the car. The need to add high-quality fuel can reduce fuel consumption to a certain extent; 2. Violent driving: When the driver drives the car too violently, the engine speed is often relatively high, which is easy to cause the car engine to overload, and the fuel consumption of the car is high.

It is necessary to change the way of driving, drive the car gently, learn to brake in advance, and start slowly; 3. Excessive carbon deposition in the engine: When the carbon deposition in the engine is too strictly prohibited, the fuel will not be transported normally, and the car will have the symptoms of fuel consumption and weak power. The carbon deposits in the engine should be removed immediately; 4. The weight of the car is too large

When the weight of the car is too large, then the load on the engine will be added, and the fuel consumption will be high. It is necessary to reduce the weight of the car.

First of all, the reasons and solutions for the high fuel consumption of Renault Koleos are as follows: 1. The added fuel quality is too low: when the fuel quality added by the car is too low, the fuel and mixed gas can not be fully burned in the engine, so it will cause part of the fuel waste, and the stool shouting will affect the fuel consumption of the car.

It is necessary to add high-quality fuel to reduce fuel consumption to a certain extent; 2. Violent driving: When the driver drives the car too violently, the engine speed is often relatively high, which is easy to cause the car engine to overload, and the fuel consumption of the car is high. It is necessary to change the way of driving, drive the car gently, learn to brake in advance, and start slowly; 3. Excessive carbon deposition in the engine:

When the carbon deposition of the engine is too strictly prohibited, the fuel will not be transported normally, and the car will have the symptoms of fuel consumption and weakened power. The carbon deposits in the engine should be removed immediately; 4. The weight of the car is too large: when the weight of the car is too large, then the load of the engine will be added, and the fuel consumption will be high.

It is necessary to reduce the weight of the car.

If none of these are the case, it means that the engine has too much carbon deposit.

1. The sensor is damaged, the contact is poor, or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. Blockage of air conditioner filter 1. Sensor problem; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add the oak as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of carbon deposition or knocking in the engine, and these will eventually be detected by the engine's oxygen sensor, and after reporting to the ECU, the fault lamp will naturally be lit to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and the engine fault light will be lit up if the serious carrying troubles are serious. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

Summary. The Renault 450 engine can have problems with lack of power, and the reasons for this can be varied. It may be due to a lack of fuel** due to oil contamination or a faulty fuel injector, or a lack of power due to a blocked air cleaner or a leak in the intake system, resulting in insufficient power.

At this time, the problem should be investigated and repaired in time to ensure the normal operation and driving safety of the vehicle.

I'm still a little confused, can you be more detailed?

Summary. Hello dear! Renault 385 engine fuel consumption: comprehensive fuel consumption between 35-38.

Hello dear! Renault 385 engine fuel consumption: comprehensive fuel consumption between 35-38.

It is caused by excessive carbon deposition in the throttle valve, idle motor, intake valve, intake pipe, combustion chamber, fiber spark plug, fuel injector, etc. Because these carbon deposits will block the idle channel, the idle motor and the bridge will roll or exceed its adjustment range, which will cause low idle speed, unstable idle speed, high fuel consumption and flameout. There are also frequent starts and stops, infrequent replacement of sensitive vertical backstops, the throttle is very large, and so on....Caused by excessive carbon accumulation in flower plugs, fuel injectors and other parts.

Summary. Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

What is the reason for the high fuel consumption of the 420 horsepower Renault engine?

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Fuel consumption per 100 kilometers is 45 liters.

Renault 420 hangs.

There are no mountain roads for normal driving.

Hello, if the engine fuel consumption is too large, the main check is the problem caused by the ignition clearance of the spark plug, in addition, clean the throttle, if the throttle is dirty, it will also cause this problem. First, check the spark plugs and then clean the throttle. Yours is a van, isn't it?

If you are a truck, check whether the front oxygen sensor is damaged.

Is there a fault in the engine now**? If there is a fault, you can refer to what causes the fault**? Fuel consumption is on the high side. If not, check the front oxygen sensor.

Diesel cars, what spark plugs.

Just now I thought you were talking about a gasoline car, if you are a diesel car, check it, the front oxygen sensor data flow is correct, and remove the fuel injector to adjust it.
