What are the reasons for insufficient engine power?

[OCora]

The reasons for insufficient engine power include: 1. Fuel supply system issues: Poor fuel quality, low cleanliness and combustion efficiency can easily lead to fuel system malfunctions, preventing the engine from operating normally; 2. Ignition system issues: Early ignition causing premature combustion and detonation of the air-fuel mixture can make the engine reverse, reducing power output. Delayed ignition can result in slow combustion of the air-fuel mixture in the combustion chamber, causing engine overheating and power loss; 3. Cylinder compression pressure: Power output is generated by the ignition of the mixture formed between gasoline and air. Insufficient air intake can cause severe cylinder wear, increasing the clearance between the piston, piston rings, and cylinder, leading to cylinder head leakage and insufficient power output; 4. Engine overheating: Too much or too little lubricating oil in the crankcase, deteriorated or dirty lubricating oil, or blocked oil passages can directly affect the engine's power output.
