The invention concerns a starter / generator for an internal combustion engine (1), especially that of a motor vehicle, with an electric rotary-field machine (4), which exercises the starter and generator function; and at least one invertor (17) for generating the voltages and / or currents of variable frequency, amplitude and / or phase required for the magnetic fields of the electric machine (4); wherein the electric machine (4) starts the internal combustion engine (1) by merging in from standstill.

A method is provided for engaging a starter pinion of a starter with a starter ring gear of an internal combustion engine during the running-down of the internal combustion engine, which internal combustion engine has an arrangement for determining rotational speed and rotational direction of a crankshaft. The starter pinion is engaged with the starter ring gear when the following conditions are satisfied: a) the speed of the internal combustion engine is below a maximum speed and above a minimum speed; and b) the rotational direction corresponds to the forward rotational direction of the crank shaft.

A stop and start control apparatus of an internal combustion engine prevents fuel supplied in a specific cylinder at the time of stopping the engine from being discharged in an unburned state. When an ignition switch is turned off in a state that the unburned fuel is sealed in the combustion chamber of a specific cylinder during idling stop, the unburned fuel is combusted to prevent the unburned fuel from being discharged. The vibration occurring at that time can be suppressed by rotating the motor generator in the counter direction to the rotation direction of the crankshaft. After the unburned fuel is sealed in the combustion chamber of the specific cylinder, if it is estimated that the unburned fuel is discharged, the exhaust valve corresponding to the specific cylinder is closed at the predetermined timing, or the unburned fuel is combusted, whereby the unburned fuel is prevented from being discharged. Thus, deterioration of emission can be avoided.

A one way isolator for high torque devices, such as alternator-starters, driven by a flexible drive means includes a hub and a sheave each of which includes at least one stop member. The hub and sheave are linked by a isolating spring and, via a bearing and / or bushing, can rotate with respect to each other to provide isolation, through the spring, from torque variations when torque is transferred from the flexible drive means to the device. When substantial amounts of torque are transferred from the device to the flexible drive means, the sheave rotates with respect to the hub to bring the stop members into contact such that the isolator then acts like a solid pulley to facilitate the transfer of the torque from the device.

A hybrid vehicle drive control system has a first clutch interposed between an engine and a motor / generator, a transmission including several gear position clutches arranged between the motor / generator and a drive wheel, and a controller. The controller selectively starts the engine using torque from the first clutch during a mode drive change from an electric drive mode to a hybrid drive mode. When an engine start command occurs during the drive mode change, the controller selects the engaged gear position clutch that has the maximum torque transfer capacity from the engaged clutches constituting a vehicle running gear occurring during an engine starting process as a second clutch to be controlled. Then the controller executes a slip control of the second clutch when the first clutch is being connected to start the engine during the mode change from the electric drive mode to the hybrid drive mode.

An engine starting system includes a throttle valve, an alternator, an engine speed sensor and an electronic control unit (ECU). The ECU functionally includes an automatic engine stop controller for automatically stopping the engine by interrupting fuel injection when predefined automatic engine stop conditions are satisfied, and an automatic engine restart controller for automatically restarting the engine when predefined engine restart conditions are satisfied. The automatic engine stop controller sets the quantity of intake air at a level higher than a minimum quantity of intake air necessary for keeping the engine running, decreases the amount of electric power generated by the alternator in an early part of automatic engine stop control operation, and decreases the quantity of intake air and causes the alternator to once decrease the amount of electric power generated thereby at a point in time when the engine speed drops down to a predetermined reference engine speed, and causes the alternator to later increase the amount of electric power generated thereby.

An all terrain vehicle (“ATV”) is disclosed having a frame with front, rear, right, and left sides. The frame defines a frame centerline extending longitudinally between the front and the rear sides. The ATV includes an engine with at least one cylinder having an axis that defines an engine centerline. The all terrain vehicle also includes an output shaft defining an output shaft centerline. A continuously variable transmission (“CVT”) operatively connects the engine to the output shaft and defines a CVT centerline. The engine centerline, output shaft centerline, and CVT centerline are positioned with respect to one another and the frame centerline. In one embodiment, the engine centerline is disposed between the output shaft centerline and the CVT centerline. In this embodiment, the engine centerline also may lie between the frame centerline and the CVT centerline.
