ABSTRACT:
An electric starter apparatus and method with three-stage gearing and method for starting an internal combustion engine. The apparatus includes a starter assembly, a first gear, a second gear, a third gear, a fourth gear and an engine shaft. The starter assembly includes an electric starter motor and a starter motor shaft communicating with the starter motor. The starter motor shaft is rotatable in response to energizing of the starter motor. The first gear is attached to the starter motor shaft for rotation therewith. The second gear engages the first gear, the third gear engages the second gear, and the fourth gear engages the third gear. The fourth gear is attached to the engine shaft for communicating with an internal combustion engine. The engine is started by energizing the starter motor to rotate the starter motor shaft, the gears, and the engine shaft. The arrangement of gears enables the use of a low-torque/high-rpm electric starter motor in combination with a nickel-cadmium battery.
