ンのノツキング回避装置。 In an engine knocking avoidance device comprising control means for controlling ignition timing to an advanced state that does not cause knocking in response to a signal from an analog circuit that detects a knocking state including a knocking sensor, a power supply is sent to the analog circuit. The present invention is characterized by comprising a means for detecting voltage, and a failure determination means for switching the ignition timing to a position delayed by a predetermined amount when the power supply voltage has decreased beyond the operation guaranteed voltage of the analog circuit based on the detected value. Engine knocking avoidance device.
