    The cast iron cylinder block and high-strength piston have excellent wear resistance and high temperature resistance, can withstand high-load operation and extend service life. Core components such as crankshafts, connecting rods and valve trains are all precisely processed and strictly tested to ensure that the engine maintains stable performance in long-term operation.

     

    Excellent Heat Resistance And Durability

    The 4G63 engine adopts an old-fashioned design that has been proven for decades, so it is highly reliable. At the same time, it adopts a high-strength cast iron cylinder block and a lightweight aluminum cylinder head, which has the greatest resistance to overheating and minimizes the risk of detonation.
