1. Overheating: Overheating of the diesel generator during operation may cause the fuel in the cylinder to self-ignite prematurely, thereby causing explosion. Overheating may be caused by factors such as cooling system failure, insufficient lubrication, or excessively high ambient temperature.
2. Intake system problems: Leakage or unstable pressure in the intake system may cause uneven fuel mixing, thereby causing explosion.
3. Fuel quality problems: Poor diesel quality or impurities may lead to poor combustion performance, which may easily cause explosion.
4. Ignition system problems: Failure of the ignition system, such as inaccurate ignition timing or insufficient ignition energy, may also cause explosion.
5. Too high cylinder pressure: Cylinder pressure exceeding the design range may cause explosion.
6. Cooling system failure: Problems with the cooling system, such as water pump failure, radiator blockage or coolant leakage, may cause the engine to overheat, increase the friction between the piston and the cylinder wall, and thus induce cylinder explosion.
7. Lubrication system problems: Abnormalities in the lubrication system, such as oil pump failure or filter blockage, will increase wear and accumulate heat, increasing the risk of cylinder explosion.
8. Improper maintenance: Neglecting regular maintenance and inspections, such as delaying the replacement of worn parts, not cleaning the filter, or not checking the fuel quality, may accelerate the occurrence of failures.
9. Using low-quality fuel: Low-quality fuel may cause incomplete combustion, generate too many impurities, clog the injectors and filters, increase the pressure in the cylinder, and directly cause cylinder explosion.
10. Improper operation: For example, adding cooling water immediately after starting, or suddenly adding cold water at high temperature, may cause the cylinder block and cylinder head to crack due to rapid cooling.
