| Introduction | After more than 10 years of market test, YC6MK series engines are widely applied in heavy buses, heavy trucks, engineering machineries, ships and generator units. After being updated to the electronically-controlled high-pressure common rail configuration, the engine meets then on-road stage III emission standards, and it has sufficient margin, stronger power, lower fuel consumption and better transient loading capacity. | After more than 10 years of market test, YC6MK series engines are widely applied in heavy buses, heavy trucks, engineering machineries, ships and generator units. Afterbeing updated to the electronically-controlled high-pressure common rail configuration, the engine meets the non-road stage III emission standards, and it has sufficient margin, stronger power, lower fuel consumption and better transient loading capacity. | YC6MK series engine after more than 10 years market trial, is widely used in heavy bus, heavy truck, engineering machinery, ship and generator set. After its configuration is upgraded to electronically-control high pressure common rail, the emission meets the requirementsfor non-road stage III; and it is characterized by sufficient margin, s tronger dynamic performance, less fuel consumption and better transient loading capability. |
