Title: Misfire judging device for internal combustion engine
Inventor: FURUYA JUNICHI
IPC: F02P17/12
Filed: 1990-12-26
Abstract: PURPOSE:To make highly precise misfier judgment without being affected by variation in accuracy of sensors provided for each cylinder and temperature drift. CONSTITUTION:When pistons are set at the same position in compression and combustion strokes for each cylinder, detected values of pressure in the cylinders are sampled (S2 to S4) and a difference between a reference cylinder inner pressure PBTDC and a comparative cylinder inner pressure PATDC is compared with a misfire judgment value MFDP (S7). When the judgment is (PATDC-PBTDC)<MFDP, misfire is produced and cylinder pressure P is set roughly symmetrical with respect to a compression top dead center(TDC) (S9). Since misfier is judged using a relative comparison, highly precise misfier judgment can be made without being affected by variation in sensor accuracy and temperature drift.
