Abstract (en)
To improve the startability by reducing the effect of a load upon start-up of an engine. When an Ne sensor (153) detects the stoppage of the engine, a control unit (1000) turns on a relay (RyA). When a starter switch is operated, a starter relay control unit (400) turns on a relay (RyA). The OFF state of the relay (RyB) is kept for a time set on the basis of the water temperature of the engine. When the relay (RyA) is turned on, the starter motor (171) is driven in such a manner as to be reversely rotated when the relay (RyB) is turned off and to be normally rotated when the relay (RyB) is turned on. In this way, the degree of the warming is decided depending on the water temperature, and when the degree of warming is large, the reverse-rotation time of the crank shaft is made short and when the degree of warming is small, the reverse-rotation time of the crank shaft is made long. The crank shaft is reversely rotated for the reverse-rotation time thus set, to be located at a position in a low load region, and is then normally rotated. <IMAGE>
When an engine speed sensor (153) detects that the engine has stopped a control unit (1000) turns a relay RyA (162). When the starter switch is next operated a starter relay control unit (400) turns ON the relay, so the starter motor (171) is driven reversely when a second relay RyB (162a) is turned OFF, and is in the normal direction when this second relay is turned ON. The water temperature is used to determine the length of the warming up period to determine the low region. The OFF state of the starter relay RyA is set according to the engine water temperature. When the degree of warming is large the reverse rotation time is made short and when the degree of warming is small the reverse rotation time is made long.
