| Abstract(J) | 図示平均有効圧(IMEP)の算出時，指圧波形を正確に計測する必要がある．一般に，上死点検出位置がずれた指圧波形からIMEPを求めると誤差を生じることが知られている．本稿では，フーリエ級数展開された指圧波形からIMEPを求める方法を利用して，上死点検出ずれによるIMEP演算誤差の原因を明確にした． Translation |
| Abstract(E) | When calculating indicated mean effective pressure (IMEP), it is necessary to measure the original cylinder pressurecorrectly. Generally producing calculation error is known, if IMEP is calculated from pressure diagram with which topdead of center (TDC) detection position deviation. In this paper, it cralified about effect to which TDC detectionposition deviation exerts on IMEP calculation result from pressure diagram by which fourier series expansion wascarried out using solicited method, and its cause. |
