What is the reason for burning oil in the Renault 420 engine?

There are many factors that affect the burning of oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc. The above reasons will aggravate oil consumption and lead to oil burning, causing the vehicle to appear: carbon accumulation in the combustion chamber, causing the gas ring of the piston ring Stuck, poor sealing.

Most of the burning of engine oil is caused by the stagnation of the piston ring. Relying on the addition of high-viscosity oil to prolong life is just an expedient measure to treat the change but not the root cause. The poor power and high fuel consumption of the engine are due to the fact that the oil participates in combustion to form more carbon accumulation, and the carbon accumulation aggravates the degree of oil burning to form a vicious circle.

This engine is a diesel engine. The factors that consume a lot of fuel in the diesel engine are: x0dx0a insufficient diesel combustion.The main reason for insufficient combustion of diesel is insufficient compression ratio, as the saying goes.

How many rpm should the Renault 420 engine be

. It is normal for the engine to idle at about 850 rm. If it is a cold car, it is more reasonable not to exceed 1200 rm.Renault S.A. It's a French car brand, a French car.

The normal idle speed of the Renault 350 engine is 500 to 800 rpm per minute.

During, the engine speed of a general electric injection vehicle is about 2200-2500. No matter which gear, the engine speed is kept at about 2200-2500. If the speed is too low, the car can't move, the fuel consumption will not walk, and the engine will be damaged; if the speed is too high, it will increase the ineffective fuel consumption, which will also damage the engine.

Did you turn on the air conditioner? If so, the speed is normal. If the air conditioner is not turned on, the speed will be high. This is very easy to do. Just adjust the idle speed.

Dongfeng Tianlong Renault 420 horsepower occasional engine jitter and lack of cylinder will be fine from the new start

1. The normal reasons for the occasional cylinder loss after restart are as follows: Ignition system: due to engine failure, The ignition coil and spark plug of the engine will fail. Once the engine fails, the engine will lose power or even shut down. Go to a professional repair shop for repair. Cylinder wire wear: Check whether the cylinder wire is working normally.

2. The engine carbon accumulation is serious. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

3. There is a problem with the engine fuel pump. After checking the information of Dongfeng Automobile, Tianlong Traction 420 lacks cylinder becauseThere is a problem with the motive fuel pump. Dongfeng Tianlong is a new generation of heavy truck platform launched by Dongfeng Commercial Vehicle Company in Shiyan City.
