STARTING CONTROL DEVICE FOR ENGINE

摘要

A reluctor projection (7a) on a flywheel (7) is set to an advanced side so that a target ignition timing can be specified after an ON period of a crank angle signal is measured. Then, for the first ignition at the beginning of the start of cranking, the target ignition timing (= ignition target time Ttgt) is specified on the basis of a measurement value of an ON period Ton(n-2) of the crank angle signal (first starting mode). For the second and subsequent ignitions, an ON period Ton(n) in a current rotation cycle is estimated on the basis of measurement values of an OFF period Toff(n-2) and the ON period Ton(n-2) in a rotation cycle two rotations before and an OFF period Toff(n) in the current rotation cycle, and the target ignition period is specified on the basis of the ON period Ton(n) (second starting mode).
