Advantages of WDM-40MA Series Engine

  • Holset supercharger with integrated wastegate valve, low speed response and strong power.

  • The Holset wastegate valve makes the low speed performance more perfect and the power performance better.

  • It is synchronized with Weichai advanced design and sophisticated manufacturing, adapts to harsh working conditions, and has high-intensity and heavy-duty work capabilities.

  • Using forged steel camshaft and crankshaft, high-strength cylinder design, many parts are cast on the cylinder, with high rigidity, high pressure resistance, good reliability and longer service life.

  • The cylinder liner adopts a platform mesh honing design, which effectively prevents oil leakage with a perfect geometric structure, and adopts advanced technology such as new piston ring components and gasket crimping molding to reduce oil loss.

  • The cylinder block and cylinder head adopt integrated design to prevent the occurrence of engine water and oil leakage. The parts are 40% less than other similar engines, and the failure rate is greatly reduced.
