| (54) | Start control device for internal combustion engine |
| (57) A target rotation angle of a crank angle between a crank angle stored upon stoppage
of a crankshaft (8) and a reference position (45b) is computed. Then, the presence
of a failure in the starting means (20) is determined based on whether a missing tooth
part (45b) is detected when the crankshaft (8) rotates by the target rotation angle
from the rotation stop position of the crankshaft (8) after an engine (1) is started
by a starting means (20). If the missing tooth part (45b) is not detected when the
crankshaft (8) rotates by the target rotation angle from the rotation stop position
of the crankshaft (8), it is determined that the starting means (20) has a failure
because there is a high possibility of a reverse rotation of the crankshaft (8) due
to a failure in the starting means (20).
