What is the engine jitter after cleaning the throttle of Peugeot 4008?
The causes of engine jitter of Peugeot 4008 include too dirty throttle or too much carbon deposited in injector, working conditions of spark plug, high voltage lead and ignition system, unstable oil pressure, engine foot aging and other factors.
Precautions for engine maintenance:
1. Clean air filter: The air filter is directly related to the air intake problem of the engine when the car is driving. If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition in the cylinder, so that the engine ignition will be blocked and the power will be insufficient, and the fuel consumption of the vehicle will naturally increase. If you drive on a normal city road, you should check the air filter when the car travels 5000 kilometers. If there is too much dust on the filter element, consider using compressed air to blow out the dust inside the filter element. But the pressure of compressed air should not be too high to avoid damaging the filter paper. He told reporters that water or oil must not be used when cleaning the air filter to prevent oil and water from soaking the filter element.
2. Discharge throttle sludge: There are many reasons for sludge at the throttle, some of which are carbon deposits formed by exhaust gas from fuel combustion at the throttle; Then, impurities that are not filtered by the air cleaner will remain on the throttle. Too much sludge will cause air resistance and increase fuel consumption. Generally, the car should clean the throttle when driving 10000 to 20000 kilometers. When cleaning the throttle valve, first remove the intake pipe, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle valve, and then carefully scrub it with a polyester rag or a high-spin "non-woven fabric". Deep in the throttle, you can clip a rag and scrub it carefully. After cleaning, the air inlet pipe and battery cathode can be installed and ignited.
3. Clean up the carbon deposit on the nozzle: because the combustion chamber is easy to deposit carbon, it will lead to difficulties in starting; Carbon deposition in the fuel nozzle will also lead to oil blockage, gasoline injection deformation, poor atomization, and fuel consumption will naturally increase. For the cleaning of the combustion chamber, a special carbon remover can be used to soften the carbon deposits on the combustion chamber and the fuel nozzle and separate them from the surface of the parts, and then remove the softened carbon deposits. This method of removing carbon has a good effect. Compared with the previous direct wiping, it has the advantage of not damaging the surface of parts, and the efficiency of removing carbon has also been greatly improved.
