Abstract

PURPOSE:To minimize the service number of expensive knock sensors by a judging level compensating device which compensating a knock judging level value of either of knock sensors on the basis of the compared result made by a comparing device. CONSTITUTION:Judging level making devices C1, C2 make out knock judging level values Vrefp, Vref of respective knock sensors A1, A2. A comparing device E compares a knock judged result of the knock sensor A1 with that of the knock sensor A2, and on the basis of this compared result, a judging level compensating device F compensates the knock judging level value Vref of the knock sensor A2. Thus, the service number of expensive knock sensor is held to the minimum.
