크랭크축 각속도를 사용한 실린더 내 압력 추정(1)

This paper describes another method to investigate combustion pressure in the cylinder without modifications of engine. Assuming engine dynamics as a single degree of freedom cylinder pressures are estimated using the variation of crank shaft speed. For this study pressure. crank shaft speed. and load were sampled by the crank angle. This study suggests the variation of crank shaft speed can be used as parameters of feedback engine control.
