摘要： Even if the engine is started from any crank angle position, it is possible to correctly determine the rotational direction of a crankshaft, so that fuel injection or ignition can be stopped when the crankshaft is rotating in the reverse direction. A measurement member has a plurality of angular position detection portions arranged at equal intervals in a circumferential direction of the crankshaft and a plurality of reference position detection portions at which a part of the angular position detection portions is missing. A crank angle sensor is arranged near the measurement member for generating a crank angle signal representative of the rotational position of the crankshaft. A period detector detects periods of pulses of the crank angle signal. A reference position determiner determines a plurality of reference positions based on the signal periods. A counter counts the pulses of the crank angle signal. A rotational direction determiner detects the rotational direction of the crankshaft from the number of pulses counted between a plurality of reference positions.

摘要： A cylinder identifying system for an internal combustion engine enables fuel injection and ignition controls for individual cylinders to be speedily performed upon starting of engine. A cylinder identifying means (10) operating on the basis of a crank angle signal (SGT) and a cam signal (SGC) includes a pulse signal number storage means (12) for dividing an ignition control period of each cylinder into plural subperiods for counting for storage signal numbers of specific pulses generated over plural subperiods, and a subperiod discriminating means (14) for determining discriminatively a sequential order of the plural subperiods on the basis of combinations of the numbers of the specific pulses generated during the plural subperiods. The combinations of the numbers of specific pulses generated during the plural subperiods differ one another correspondingly to the plural subperiods independently from the start points thereof. The cylinder identifying means (10) identifies the individual cylinders on the basis of results of determination made by the subperiod discriminating means (14) independently of positional relationships between the storage start points and the subperiods.
