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 6LTAA8.9-C240 Pump Engine

  • Leading design and excellent manufacturing technology make the engine more reliable and durable, suitable for high-strength, heavy-duty work under severe working conditions.

  • Advanced four-valve structure, greater power, more thorough air combustion, higher low-speed torque and higher operating efficiency.

  • Forced cooling articulated pistons are used to withstand higher mechanical and thermal loads, comparable to the strength of heavy-duty engines.

  • Enhanced cylinder design, significantly reducing noise and vibration.

  • Powerful driving air-to-air cooling and turbocharging technology, better engine power.

  • The use of central fuel injector, the combustion chamber is symmetrical, the mixing in the cylinder is more uniform, the combustion is more thorough, and the emission is lower.

  • The size of the engine is smaller than that of the same type of engine, the maintenance space is large, and the maintenance is faster.

  • Strong interchangeability, more convenient equipment upgrades.
