In addition to overcoming the friction resistance of various parts of the engine and driving various auxiliary devices (such as water pump, fuel injection pump, fan, air compressor, generator, oil pump, etc.), the force generated by the combustion of fuel in the engine cylinder and the work done by gas expansion finally outputs the power outward through the flywheel.
Insufficient oil supply causes engine weakness
Poor spray quality causes engine weakness
Effect of injection advance angle
Effect of inflation
Poor sealing of parts containing working medium
Effect of ambient temperature
Effect of engine resistance
Diagnose according to the analyzed causes and fault phenomena.
5. Check for air leaks
6. Check engine resistance
7. Check valve timing
