Yuchai Yc4a Diesel Engine for Excvavtor, Construction Machinery.

We specialize in original YUCHAI  diesel engine,YC4A series diesel engine for construction machinery.

Main components in finite element analysis, optimized design using the new technology of vibration noise reduction, reasonable mechanical parts, the machine has compact structure.


Adopting Germany FEV combustion, simulation calculation means such as breath, lubrication, cooling, ensure the engine fuel consumption and low noise, low power performance is strong, long life and high reliability.

Using the mature domestic AD type fuel injection pump and the speed governor, the rate is low, diesel engine speed stability, high speed constant power and constant torque at low speed.

With large flow pump, built-in cooler cooling ability


The high-performance turbocharger, more fuel-efficient.
