Advantages of Fast 7DS90B MT Parts
It is synchronized with CMI’ advanced design and sophisticated manufacturing, adapts to harsh working conditions, and has high-intensity and heavy-duty work capabilities.
The Holset wastegate valve makes the low speed performance more perfect and the power performance better.
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.
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.
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.
