Internal combustion engine cylinder operation controlling method for motor vehicle, involves opening exhaust valve between exhaust valves opening and closing times, where closing time is between opening times of two inlet valves

摘要

The method involves opening an exhaust valve between exhaust valve opening and closing times, and opening one inlet valve between a primary inlet valves opening and closing times. Another inlet valve is opened between secondary inlet valve opening and closing times, and fuel is injected, during a same operation cycle of a cylinder. The exhaust valve closing time is between opening times of the two inlet valves. An independent claim is also included for a motor vehicle having an internal combustion engine.
