Damage caused by low water temperature to diesel generators:
1. Low temperature will worsen the combustion conditions of diesel in the cylinder, poor fuel atomization, increase the combustion period after ignition, the engine will run easily. , and the crankshaft will be worsened. Damage to bearings, piston rings and other parts will reduce power and reduce economy.
2. Water vapor after combustion easily condenses on the cylinder wall, causing metal corrosion.
3. Burning diesel can dilute engine oil and worsen lubrication conditions.
4. The fuel is not completely burned and forms a colloid, which causes the piston ring to become stuck in the piston ring groove, the valve to become stuck, and the pressure in the cylinder to decrease at the end of compression .
5. If the water temperature is veryop low, the engine oil temperature will also be low. The engine oil will become thicker and the fluidity will become poor. The oil pump will have less oil, resulting in insufficient oil. oil supply. In addition, the crankshaft bearing clearance will become smaller and lubrication will be poor.
