Abstract

A manifold alternator generator including a turbine located proximal to a flow of exhaust gases in an internal combustion engine where the exhaust gases energize the turbine and produce rotation of an output shaft. The output shaft is connected to a rotor that is engaged with a generator such that the rotation of the turbine and output shaft generates electrical power. The manifold alternator generator may be used in combination with electromagnetic valve actuators and a flywheel alternator/starter. A processor may be used to optimize the performance of the manifold alternator generator and other system components.
