Abstract: A power transmission system transmits power from a drive shaft of an internal combustion engine to a first and a second auxiliary device through a belt. An auto-tensioner extends or contracts to change the tension of the belt. A controller rotates the first auxiliary device in a reverse direction to loosen the belt to cause the auto-tensioner to extend to increase the tension of the belt and calculates a reversing timing when the drive shaft will be reversed as a result of increasing of the tension of the belt. The controller inhibits the tensioner body from contracting immediately before or when the reversing time is reached to keep the tension of the belt at an increased degree, thereby eliminating the slippage of the belt on each pulley without having to finely control the operation of the first auxiliary device when the internal combustion engine is started.

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.

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.
