Apparatus for detecting a crankshaft position at which maximum cylinder pressure appears |
摘要 |
An apparatus for detecting a crankshaft angular position theta pmax at which the cylinder pressure reaches its maximum level. The apparatus samples a cylinder pressure indication signal at a predetermined target crankshaft angular position and at crankshaft angular positions advanced and retarded by a predetermined number of degrees of crankshaft rotation so as to accumulate three sets of data. The sampled three sets of data are used to determine a binominal equation defining the cylinder pressure as a function of crankshaft angular position. The apparatus calculates a maximum cylinder pressure value and a corresponding crankshaft angular position theta pmax from the determined binominal equation.
