Engine starter

摘要

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.
