Abstract: A power transmission system transmits power from an internal combustion engine to a first and a second auxiliary device through an endless transmitting member. Prior to issuing of an engine start request, the first auxiliary device is actuated to move a tensioner pulley to a given position to increase the degree of tension of the endless transmitting member. The actuation of the first auxiliary device as an engine starter upon the issuing of the engine start request, therefore, enables a drive shaft of the engine to be rotated immediately within a required time to crank the engine. This achieves a quick start of the engine and results in a decrease in amount of time between the issuing of the engine start request and the actual start of the engine.

Abstract: A control apparatus for an internal combustion engine is provided which works to control an electric motor to start the engine through a belt transmission system. The control apparatus restricts rotation of the electric motor so as to keep a speed of the electric motor below a speed at which the electric motor is capable of producing a maximum torque until a given period of time passes since the electric motor is actuated to start in the motor mode. This enables the electric motor to generate the maximum torque when it is required to crank the engine.
