Abstract:
1. A system for operating a multiple cylinder internal combustion engine, the system comprising: a first mode wherein a device for closely coupling the engine to a drive train such that the drive train components generate a rotational inertia reaction torque in a direction opposite rotational inertia reaction torque generated by the engine to reduce transmission of vibration associated with combusting air-fuel mixtures in all cylinders of the engine; a second mode wherein the device for closely coupling the engine to the drive train generates a rotational inertia reaction torque in a direction opposite rotational inertia reaction torque generated by the engine to reduce transmission of vibration associated with operating the engine in a reduced displacement mode; and a controller to alternate operation between the first mode and the second mode in response to operating conditions.
