Determining internal combustion engine control times, involves drawing conclusions about valve control time at which exhaust valve opens from deviations between computed, measured pressure or gradient

摘要

The method involves measuring the pressure in a combustion chamber with a combustion chamber pressure sensor, computing a theoretical pressure value or curve from the pressure measured after the end of combustion and drawing conclusions about the valve control time at which the exit valve opens from deviations from the measured pressure or gradient.
