Heavy duty truck application plastic engine

The truck engine oil and gas shell, as the core component of the separation of the engine lubrication system from oil and gas, is a "invisible guard" that ensures the stable output of power under heavy load conditions. It is specially designed for rigorous scenarios such as long-distance transportation and heavy-duty operations. Material selection to withstand extreme tests In view of the long-term high-load operation of truck engines, the main body of the shell uses high-strength gray cast iron (HT300), which eliminates internal stress after aging treatment, and has a tensile strength of more than 300MPa, which can withstand the continuous pressure caused by long-term erosion of engine oil and cylinder vibration. The inner wall adopts precision boring process, and the surface roughness is controlled within Ra1.6μm, which reduces the oil flow resistance while reducing friction loss with internal parts. For high-temperature areas (near the exhaust manifold side), an additional 3mm wall…
