[0004] Typically, the airflow in the engine varies considerably as the speed of the internal combustion engine varies between 500 rpm and 6,000 rpm. In a reciprocating internal combustion engine that controls the flow of air and exhaust gas by opening and closing the intake valve and exhaust valve, in order to obtain greater power at high speeds, it is necessary to increase the charging efficiency by lengthening the opening time of the intake valve, which makes The overlap with the exhaust valve becomes large...
