What are the reasons for engine failure to start?

[StLogan]

Engine failure to start can be attributed to the following reasons: 1. Fuel supply system failure: blockage in the low-pressure fuel line, loose pipes causing fuel leakage, air in the high-pressure fuel line, poor technical condition of the fuel injector, incorrect fuel injection timing angle; 2. Starting device failure: power supply issues, poor contact in the electromagnetic switch, poor contact between the starter motor commutator and brushes, clutch slippage in the starter transmission mechanism; 3. Insufficient cylinder compression pressure: cylinder head gasket damage causing air leakage, improper valve closure leading to air leakage, wear in piston cylinder liners causing air leakage; 4. Insufficient air intake: clogged air filter element. An engine is a machine capable of converting other forms of energy into mechanical energy, applicable both as a power generation device and as a complete machine including the power unit.
