Abstract
An apparatus and process for starting internal combustion engines having one to three cylinders by first activating a reverse direction motor to drive the power system of the engine in reverse to its normal operating direction until it is positioned at or near the backside of a prior compression stroke and then activating a starter motor, preferably at initial high torque, and continuing operation until the engine is started. The apparatus and process achieves a significant decrease in the size and power requirements for starters.
