1. Monitor It can collect, organize and display some parameters in diesel engine operation, and output alarm signal for parameters beyond the predetermined value. ![图片2](https://hackmd.io/_uploads/rJwpjimxC.png) https://wdpart.com/ 2. Starter The starting devices of the engine are: electric starter, electromagnetic meshing starter, decelerating starter, permanent magnet starter and air starter ![图片3](https://hackmd.io/_uploads/rkxRsoQgC.png) 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. ![图片4](https://hackmd.io/_uploads/r1xJ2iXeA.png) 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. ![图片5](https://hackmd.io/_uploads/HyDe2sQeR.png) 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.
