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.

Advantages of DCEC 6LTAA8.9-C240 Industrial Engine

  • Through the optimization of the control strategy and the actual use of the equipment, the fuel economy is further improved.

  • The advanced product platform and optimized design make the economic fuel consumption area of the engine wider, which is about 5 – 8 % less fuel than the same type of engine.

  • All models have strong versatility, high degree of serialization, and easy maintenance.

  • Longer equipment maintenance cycle up to 400 hours.

  • The failure rate is low, the average maintenance time and cost are about half of the same type of engine, and the working time is longer.

  • Forced cooling hinged piston is adopted, which can withstand extremely high mechanical load and thermal load, and has good strength.
