6CTA8.3-G1 G-Drive Engine

DCEC 6CTA8.3-G1 generator drive engine is a 6-cylinders in line,8.3 liter four-strokes engine with 114mm bore and 135mm stroke. Equipped with BYC PB pump and RSV governor, comes with turbocharger and Water-Air intercooler.

The prime power for 50HZ generator set (1500RPM) of DCEC 6CTA8.3-G1 generator drive engine is 163 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. All models have strong versatility, high degree of serialization, and easy maintenance.
2. Advanced design and manufacturing: excellent manufacturing technology, reliable and durable.
3. Bosh in-line fuel pump: it burns more fully under high injection pressure, has less energy loss, stronger power, and stronger fuel adaptability.
4. Good reliability The integrated design of cylinder block and cylinder head prevents water and oil leakage of the engine. There are 40% fewer parts than the same type of engine, and the failure rate is greatly reduced.
5. The overall cylinder design is adopted, the parts are about 25% less than similar products, the failure rate is less, and the maintenance is convenient.
6. The cylinder liner adopts plateau honing cross cover, corrosion-resistant high-nickel cast iron piston, which greatly reduces oil loss and improves durability and service life.
