China Yuchai - YC6A Series 240-280 HP CR Diesel Engine for vehicles

Features And Benefits

Higher reliability - can bear the pressure up to 150 bar:
> Cylinder head with low vortex & low resistance airflow passages ensuring stable performance;
> Reinforced & optimized skirt of the cylinder block, smaller deformation & higher stability of performance;
> Wet type cylinder liner with higher body & supported from the bottom ensuring higher reliability & better maintainability;
> Adopting the technique of piston forced cooling;
> Adopting the technique of cylinder block water jacket with higher top ring;
> Adopting the pressure balancing technique of fuel-gas chamber of the crankcase;
> Built-in oil cooler ensuring higher cooling efficiency;
> Adopting Holset (Wuxi) new HX40W turbocharger with the air relief valve featured by better dynamic characteristic.
