Abstract
An apparatus and method for starting an engine having a starter generator for providing a rotational force to a pulley in order to provide the necessary torque to start an engine. The starter generator also receives a rotational force to the pulley wherein the starter generator generates a current when the pulley receives the rotational force. A valve deactivation system reduces the compression in a cylinder of the engine, thereby reducing the torque required to perform a starting sequence of the engine, either permitting this apparatus to be applied to larger engines, lower ambient temperatures, or some combination thereof.
