What is the cause of body shake? How to avoid it

The most common cause of car jitter with carbon deposits may be that the throttle valve is too dirty and the injector has too much carbon deposits. After a few kilometers of driving, the dirty throttle will lead to the untidy closing of the throttle or the motor sticking, which will lead to the high idle speed of the engine, and the carbon deposit generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine shake will be more serious than usual, and sometimes it will even fail to start once. Therefore, when the car body is shaking, the throttle and throttle should be checked first. If it is found that the throttle is too dirty or the fuel nozzle has too much carbon deposit, it should be cleaned with fuel nozzle cleaning agent and throttle cleaning agent in time.

Check the working conditions of spark plugs, high-voltage lines and ignition coils. The ignition system is not easy to use, and the spark plug is not in good condition, which will also lead to this failure.

Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.

Fuel nozzle (fuel

spray

Nozzle), itself is a normally closed valve. When the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at a high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, forming a mist, which is beneficial to full combustion.

Spark plug

Plug), commonly known as crater. The function of the spark plug is to discharge the pulse high-voltage electricity from the high-voltage line (burner line), penetrate the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixture in the cylinder. The main types are: quasi-spark plug, edge protruding spark plug, electrode spark plug, seat spark plug, pole spark plug, surface jumping spark plug and so on. The cooperation of spark plug with ignition system and fuel supply system makes the engine do work, which largely determines the performance of the engine.
