Advantages of 6LTAA8.9-C340 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.
