Advantages of Caterpillar C4.4-75 Marine GenSet
-
It is synchronized with Cummins’ 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.
-
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.
-
Holset supercharger with integrated wastegate valve, low speed response and strong power.
