Abstract

A rotary internal combustion engine capable of operating under compression ignition, comprises a cylinder bore in a stator sealed between parallel end walls, an engine shaft journaled in the end walls, concentric with the cylinder bore, an air-compressing rotor keyed eccentrically to the engine shaft, the rotor generally annular, traveling clockwise, a wiper vane across its head sucking in air through a one-way inlet port in the perimeter of the cylinder bore, at the same time compressing the air ahead of it which was inhaled during the preceding revolution. The rotor compresses air into a combustion-expansion chamber formed inside the elbow of an L-shaped abutment coextensive with the end walls, the abutment with a clockwise end pivoted in a shallow seat in the face of the cylinder at about 2:00 o'clock, the base of the abutment, a plate generally rectangular, reaching counter-clockwise, thence turning upward to form an arcuate extension to reciprocate in a channel in the stator head, a fixed casting adjacent the base of the channel closing the upper part of the combustion-expansion chamber to serve as a compression head, the base of the abutment riding on the eccentric rotor.
