Abstract

The purpose of this document is to introduce the design of a new type automobile engine & powertrain. The engine emulates, as closely as possible, the operation of the electric vehicle, and, as such, uses no starter and develops 100% torque at zero speed. It is lighter in weight and operates at a higher compression ratio than the standard automobile engine, while running on lower-octane gasoline. It only runs when power is needed at the wheels. Because it is more efficient than either the standard engine or the hybrid when running, and because it is off considerably more of the time than the hybrid, it can obsolete both.
