Differential valve timing with twin-scroll turbine

An internal combustion engine is configured to periodically open and close combustion chamber exhaust valves of the engine such that one exhaust valve is held open longer than another exhaust valve and/or one exhaust valve opens before another exhaust valve relative to top dead center. The resulting...

More Information
Summary:An internal combustion engine is configured to periodically open and close combustion chamber exhaust valves of the engine such that one exhaust valve is held open longer than another exhaust valve and/or one exhaust valve opens before another exhaust valve relative to top dead center. The resulting differential exhaust valve timing can at least partially compensate for different swallowing capacities of the scrolls of a twin-scroll turbine. 一种内燃发动机，其被构造成周期性地打开和关闭发动机的燃烧室排气阀，使得一个排气阀打开的时间比另一个排气阀长，和/或一个排气阀相对于上止点在另一个排气阀之前打开。由此得到的差动排气阀正时可以至少部分地补偿双涡卷涡轮的涡卷的不同通流能力。
