title: Here is a list of one hundred diesel engine parts

---


1. Monitor
It can collect, organize and display some parameters in diesel engine operation, and output alarm signal for parameters beyond the predetermined value.

3.Oil pump assembly
It ensures the oil pressure and flow required for engine lubrication.

4. Oil filter
The oil filter is used to filter the metal debris in the oil, mechanical impurities and the oxidation of the oil itself. The quality of the oil filter directly affects the overhaul period and service life of the internal combustion engine.

5. Generator
The generator supplies power to electrical equipment and charges batteries.

6. Water pump assembly
The pump pressurizes the cooling water to ensure its circulation in the cooling system.

7. Piston
The role of the piston is to withstand the pressure of the gas in the cylinder and pass this force to the connecting rod.

8. Piston ring
Piston rings are divided into gas rings and oil rings. The function of the gas ring is to ensure the seal between the piston and the cylinder wall to prevent the high pressure gas above the piston from leaking into the crankcase. The main function of the oil ring is to scrape off the excess oil on the cylinder wall and flow back to the crankcase to reduce the consumption of oil.

9. Crankshaft
The crankshaft is the main rotating part of the engine. After the connecting rod is installed, the reciprocating motion of the connecting rod can be transformed into rotating motion.

10. Cylinder head
Its function is to seal the top of the cylinder and the piston and cylinder liner together to form a closed cylinder working space.

These are 10 of the 100 diesel engine parts list, the rest of which we will update in a future blog post.
