Abstract
In a starting control system for an internal combustion engine, an output shaft is rotated in a reverse direction at a predetermined direction upon start of the internal combustion engine, and then is rotated in a normal direction so as to start a cranking operation. The system serves to combust the fuel in a cylinder in an expansion stroke when the output shaft is rotated in the reverse direction, and the resultant combustion pressure is used for performing the cranking operation. This makes it possible to reduce the load exerted to the electric motor.
