The carbon deposit here includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit and so on. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, it will reduce the ignition energy of the car and the intake efficiency, which will eventually lead to the car shaking and insufficient power.

Solution: Go to the 4S shop to carry out the carbon deposit cleaning project, but "suit the remedy to the case" according to the actual situation, and don't blindly choose the cleaning project that has little impact on the car.

2. Fuel

Adding an inappropriate fuel label (such as 90 plus 93), resulting in a decrease in the output power of the car; Or because the vent hole of the fuel tank cover is blocked, the fuel tank switch, the fuel filter and the oil pipe between the fuel tank and carburetor are partially blocked, which can not meet the required oil supply, resulting in too lean mixture and insufficient power when the engine works.

Solution: Use the fuel label suitable for your engine according to regulations, do regular maintenance, and clean the fuel system of the engine according to the actual situation.

Step 3 inhale

Air is one of the power sources of the engine. If the air filter is not cleaned in time for a long time, it will be blocked, and insufficient air will cause the combustible mixture to be too rich and reduce the engine power. If it is a vehicle with a turbocharger, once the turbocharger fails, it will also lead to insufficient power.

Solution: Clean the air filter regularly, and replace it in 4S shop after a certain maintenance period.

4, the engine overheating

Insufficient engine oil, engine coolant, engine radiator failure, etc. It will increase the load of the engine and even lead to poor heat dissipation of the engine. Overheating of engine will cause poor lubrication effect, increase mechanical wear, reduce engine power and increase fuel consumption.

Solution: Check the liquid level of engine oil and coolant regularly, do not mix different types of engine oil, and use water instead of coolant for regular maintenance.

Other reasons for the lack of automobile power

1, the piston, piston ring and cylinder are seriously worn, which leads to the increase of the fit clearance between the piston, piston ring and cylinder, the deterioration of sealing performance, the air leakage of cylinder head and the reduction of cylinder compression pressure.

2. Improper adjustment of valve clearance, inaccurate valve timing and lax valve closing affect the reduction of cylinder pressure and insufficient engine power.
