Abstract
An engine control system in which a rotary body rotates in association with a crankshaft of an engine and has portions to be detected every predetermined angle and at least one of the portions to be detected is missing, and a pickup is arranged near an outer periphery of the rotary body and generates a pulse each time the portion to be detected passes. In the case where a reference time point to start a measurement of a time until a control start time point to start a predetermined control of the engine is a rotational angle time point of the crankshaft when no pulse is generated from the pickup due to a missing portion to be detected, a timer is allowed to measure the time from a generation time point of the pulse generated from the pickup just before the non-pulse generation period of time during which no pulse is generated until the control start time point.
