Reasons for reduced engine power and weakness
1. Carbon deposition problem
The carbon deposits here include cylinder carbon deposits, throttle valve carbon deposits, spark plug carbon deposits, intake carbon deposits, etc. These positions are closely related to the engine's power output. When the engine's internal carbon deposits are too much, the ignition energy of the car will decrease. The reduction in air efficiency will eventually lead to a reduction in the power of the engine and a weak idle speed.
2. Fuel system
Adding an unsuitable fuel label (for example, No. 93 is added to No. 90), resulting in a decrease in vehicle output and power; or because the vent of the fuel tank cap is blocked, the fuel tank switch, fuel filter, and fuel tank to the carburetor are blocked. Part of the oil pipe is blocked, which cannot meet the required oil supply, resulting in the mixture is too thin and the engine is unable to accelerate.
3. Air intake
Air is one of the power sources of the engine. If the air filter is not cleaned in time for a long period of time to cause blockage, 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 supercharging device fails, the power of the car's engine will also be reduced or weak.
4. The engine is overheated
Insufficient engine oil, insufficient engine coolant, and malfunction of the engine's heat dissipation device will increase the load on the engine, and even cause poor heat dissipation of the engine. Engine overheating will cause poor lubrication effect, increase mechanical wear, reduce engine power, and increase fuel consumption.
Other reasons for reduced or weak engine power
1. Severe wear of the piston, piston ring, and cylinder causes the gap between the piston, piston ring and the cylinder to increase, resulting in poor sealing performance, resulting in air leakage from the cylinder head and lowering the compression pressure of the cylinder.
3. Improper adjustment of valve clearance, inaccurate valve timing, tight valve closing, affecting cylinder pressure reduction, and insufficient engine power.
3. Due to the poor sealing of the crankcase, air leakage reduces the suction
