Why did the component wear performance decrease after the diesel generator was recycled?
1. Low engine coolant temperature can lead to premature wear of the unit due to excessive gaps between the cylinder liners and pistons in the generator, causing vibration and early wear as the piston moves within the cylinder. Be aware that the operating temperature for the engine unit is between 80-95°C. If the generator temperature exceeds 105°C, the unit must be immediately shut down for processing; otherwise, severe scoring or knocking incidents may occur.
2. Formation of Grey Smoke: The majority of grey smoke is caused by incomplete combustion of gasoline and diesel. The particle size of grey smoke is generally between 0.05-1 millimeter, and most grey smoke can pass through regular filters. However, due to the electric particles in the grey smoke, which are attracted to each other like magnets, they can coagulate into lumps. Thick and sticky grey smoke can increase engine oil viscosity, leading to the formation of dirt and sediment, which can obstruct oil passages and filters.
3. Oxidation and aging of engine oil. Gasoline and diesel, when burned with air, produce oxidation and nitrogen oxides. Solution: To control the oxidation of engine oil, it is necessary to add antioxidants, which can deactivate the catalytic effect of metals on oxidation, achieving the purpose of preserving the oil quality and protecting the machinery.
4. Loss of Viscosity: Due to varying operating temperatures of the engine, the loss of viscosity can lead to engine wear.
