YC6AT series diesel engines are newly developed high-performance power with power coverage of 160 to 200 hp at the speed of 2000 YC6AT series diesel engines are of the new generation up to the international advanced level. The average overhaul period of engine is more than 10000 hours. They are also characterized by bigger torque reserve of over 40%, larger torque at low speed, quicker response of acceleration and stronger capability to overcome any difficulty resulted from sudden change on the site. They meet the Euro-II standard of emission by adopting the advanced turbocharger technique and matching with the advanced fuel combustion system.4、Main Technical Parameters
