What's wrong with the strong engine shaking

1. The fuel system is blocked or malfunction, due to the blockage of the ventilation hole of the fuel tank cover, the fuel tank switch, fuel The oil pipe between the filter and the fuel tank and the carburetor is partially blocked, resulting in the inability to get the corresponding amount of fuel when the car is idling, resulting in the mixed gas becoming thinner, the engine power output becomes weaker, and the idle speed shakes;Spark plug problem.

2. Reason 1: Engine cylinder is missing. Engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, which is generally manifested as: the exhaust gas flowing out of the car has obvious intermittentity, and the exhaust pipe shakes violently. The engine shaking can be clearly felt, sometimes accompanied by abnormal sounds. This is mostly related to the failure of the ignition coil.

3. There are many reasons for engine shaking, such as tire bulge, steel rim deformation, uneven brake disc, steering machine failure, drive semi-shaft accentricity, intake system failure, fuel supply system failure, ignition system failure, etc.

What's the matter with the serious shaking of the engine?

Engine lack of cylinder, engine lack of cylinder mainly refers to one or more cylinders in the engine that are not working properly, which is manifested as: the exhaust air flow discharged by the car has obvious intervals, and the exhaust pipe shakes heavily, which can obviously feel the shaking of the engine, sometimes accompanied by a sudden sound.

There are many reasons for engine shaking, such as tire bulging, steel rim deformation, flat brake disc, steering machine failure,Drive semi-axle different center, air intake system failure, oil supply system failure, ignition system failure, etc. may be caused.

Causes for serious engine shaking: the fuel system is blocked or malfunctioned, such as partial blockage of fuel tank switches, fuel filters and other oil pipes, resulting in insufficient fuel and thin mixture when the car is idling. In addition, the failure of the spark plug will also cause the ignition system to be poor, resulting in unstable operation during idling.

The reasons for engine jitter are as follows: engine cylinder deficiency: engine cylinder deficiency mainly refers to the abnormal operation of one or more cylinders of the engine, usually manifested as the car has obvious intermittent exhaust flow, and the exhaust pipe shakes violently, so the engine shaking can be clearly felt, sometimes accompanied by sudden noise. Sound.

The reason for the serious shaking of the engine is internalThe specific reasons and solutions for excessive carbon accumulation and lack of cylinders in the engine are as follows: excessive internal carbon accumulation: carbon accumulation occurs in the valve and air intake of the engine, which can absorb an appropriate amount of fuel and cannot meet the required power performance, resulting in the car starting to shake. The solution is to clean the system.

What is the reason for the strong engine shaking

The throttle valve is too dirty or the fuel injector has too much carbon, and the ignition system problem. For the problem of the ignition system, it is necessary to check the working condition of the spark plug, high-voltage conductor and ignition coil. The poor operation of the ignition system and the poor condition of the spark plug jumping will also lead to such failures. Too much carbon needs to be cleaned up in time.

The reasons for engine shaking are as follows: engine cylinder deficiency: engine cylinder deficiencyIt mainly refers to the abnormal operation of one or more cylinders of the engine, which is usually manifested as the obvious intermittent exhaust flow of the car and the violent shaking of the exhaust pipe, so the engine shaking can be clearly felt, sometimes accompanied by a sudden noise.

The reasons for the serious shaking of the engine are excessive internal carbon accumulation and lack of cylinder in the engine. The specific reasons and solutions are as follows: excessive internal carbon accumulation: carbon accumulation occurs in the valve and air intake of the engine, which can absorb an appropriate amount of fuel and cannot meet the required power performance, resulting in the car to start shaking. The solution is to clean the system.

The main reason for idling jitter: serious engine carbonization: cars always have the problem of carbon accumulation, including cylinder carbonization, throttle carbonisation, spark plug carbonization, intake carbonisation, etc.
