Isuzu 4JG1T Series Engine

Advanced design and sophisticated manufacturing, adapt to a variety of harsh working conditions, high-intensity, heavy-duty work ability.

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

The cylinder bore adopts a platform mesh honing design, the perfect geometric structure effectively prevents oil leakage, and adopts advanced technologies such as new piston ring components and gasket crimping molding to reduce oil loss.

Adopt Holset supercharger with integral wastegate valve, low speed response and strong power.

The three-stage fuel filter ensures a balanced level of particle dispersion, protects the main components of the fuel system, and maximizes the life of the engine.
