6BT5.9-G1 G-Drive Engine

DCEC 6BT5.9-G1 generator drive engine is a 6-cylinders in line,5.9 liter four-strokes engine with 102mm bore and 120mm stroke. Equipped with Weifu A pump and RSV governor, comes with turbocharger.

The prime power for 50HZ generator set (1500RPM) of DCEC6BT5.9-G1 generator drive engine is 86 kW.

As part of EMAC, SinoGen also provide complete power supply solutions that powered by DCEC, our ranges of products including open type generator set, silence type generator set, super silence type generator set, mobile trailer, complete power truck and complete power car for railways applications. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

1. 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.
2. The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water leakage and oil leakage.
3. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
4. Forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block. high rigidity, high pressure resistance, good reliability, and longer service life.
