The world's first fully variable valve commercial vehicle heavy-duty engine was successfully ignited in Yuchai

The engine was successfully ignited，It marks a major breakthrough in the field of commercial Vehicle engine with fully variable valve technology.，Opening a new era in the commercial transportation industry；At the same time，It is also an important milestone for Yuchai to explore the frontier technology of commercial Vehicle power system industry.，Yuchai has taken another step towards the goal of building a world-class green intelligent power system production base and R & D technology center.。

It is reported that，Fully variable valve train enables valve timing、Continuously variable opening duration and lift，By mean of valve opening and close time under various working conditions of that engine,、Optimal adjustment of valve lift，And that exhaust emission is reduce to the maximum extent.，Thereby improving the fuel economy of the engine.，Increase the output torque，Reduce emission pollution。In addition，The engine also supports cylinder deactivation，The combustion efficiency can be further improved.、Reduce fuel consumption。Application of Fully Variable Valve Train，It will greatly enhance the market competitiveness of Yuchai heavy-duty engine.，To provide new kinetic energy for further seizing the heavy machinery market。
