Exhaust gas recirculation method for multi-cylinder, self-ignition V-stroke piston internal combustion engine, involves designing stroke height and/or opening time of extended opening of one exhaust value opposite to other valves

摘要

The method involves designing the stroke height and/or opening time of the extended opening of one exhaust value, opposite to the remaining exhaust valves. A post opening of the valve is provided instead of the extended opening of the valve. A partial opening is provided between a main opening and the post opening, where the partial opening corresponds to a cutting depth between the main and post openings.
