Before using a small diesel generator, it is essential to check the oil, coolant, cables, circuit breakers, control systems, and other items. If there is a problem with the project, it will affect the safe operation of the small diesel generator.
1. Lubrication:
As long as a small diesel generator is running, friction develops in the internal parts. The faster the speed, the more intense the friction. For example, the temperature of the piston parts can reach more than 200 degrees Celsius. When there is oil in the diesel generator set, the temperature will be so high that the entire engine will be burned. One function of engine oil is to use an oil film to cover the metal surfaces inside the engine to reduce frictional resistance between the metals.
2. Heat dissipation function:
In addition to the cooling system, the oil also plays an important role in the heat dissipation of the unit itself, as the oil flows through the inside of the engine and takes away the heat generated by the friction of the parts and parts.
3. Cleaning effect:
Carbon and combustion residues from long-term engine operation can adhere to the inside of the engine. If not handled properly, it will affect the function of the engine, especially since these things accumulate on the piston rings, intake and exhaust valves. Carbon deposits or sticky substances are produced, leading to knocking, frustration, and fuel consumption. These phenomena are the enemy of the engine. The oil itself is a cleaning and dispersing agent that prevents these carbons and residues from accumulating inside the engine, allowing them to form small particles and remain suspended in the oil.
4. Anti-corrosion and anti-rust effect:
After the small diesel generator runs for a period of time, various corrosive oxides will naturally form in the oil, especially the strong acids in these corrosive substances, which are likely to corrode the inside of the engine; At the same time, although most of the moisture produced by combustion is carried away by the exhaust gases, a small amount of moisture remains and therefore damage the engine. Therefore, additives in engine oil have anti-corrosion and anti-rust functions to protect the engine from these harmful substances.
