Why did the performance of the components decrease after the diesel generator was recovered and found to have worn down?
1. Low engine coolant temperature can lead to premature equipment wear due to excessive clearance between the cylinder liners and pistons in the generator. This excessive movement of the piston within the cylinder causes vibration and early wear. Keep in mind, the operating temperature for the engine unit is between 80-95°C. If the generator unit temperature exceeds 105°C, the unit must be immediately shut down for processing. Failure to do so can result in severe scoring or seizing of the engine.
2. Formation of Gray Smoke: The majority of gray smoke is produced due to incomplete combustion of gasoline and diesel. Most gray smoke particles, ranging from 0.05 to 1 millimeter, can pass through regular filters. However, as the smoke carries charged particles that attract each other like magnets, they can凝结 into clumps. Thick and sticky gray smoke can increase engine oil viscosity, causing debris and sediments to obstruct oil passages and filters.
3. Oxidation and aging of engine oil. Gasoline and diesel, when burned with air, produce oxidation and nitric oxide. Solution: To control the oxidation of engine oil, antioxidants must be added to钝ize the catalytic effect of metal on oxidation, thereby achieving the purposes of maintaining oil quality and protecting the machine.
4. Loss of Viscosity: Due to varying operating temperatures of the engine, the loss of viscosity can lead to engine wear.
