Yuchai Diesel Engine is made by Germany equipment, MTU technology
With integral cast iron crankshaft, alloy cast iron cylinder number head, the engine has the advantages of compact size, ligh weight, less vibration, low noise and high reliability.
4-Valve with electronics unit pump (EUP) injection system and advanced injector provide better combustion, lower fuel consumption.
Dual thermostats with gear driven water pump improve reliability and cooling efficiency.
User friendly with low emissions.
More power reserve, better performance.
Good parts commonality.
1) Advanced technology in turbocharged & intercooled and electronically controlled fuel injection system supports better combustion, faster transient response stronger load acceptance, and improves emission.
2) High-strength cylinder block, alloy forged steel crankshaft and connecting rods, and pistons with inner cooling oil channel, prolongs engine life with lighter and compact size
3) Comply with Emission standard T3 & Stage 3A.
