Advantages of DCEC 4B3.9-G11-A G-Drive Engine
Efficient and fuel-saving: the cylinder bore adopts a platform mesh honing design; the perfect geometric structure effectively prevents oil leakage.
adopts advanced technologies such as new piston ring components and gasket crimping molding to reduce oil loss.
Manufacturing process: The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage.
The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
Strong power: adopts Holset supercharger with integral wastegate valve, low-speed response and strong power.
Advanced design and high-quality manufacturing, adaptable to severe operating conditions, high strength, and reliable operation under heavy load.
