Abstract

An internal combustion engine of the rotary type has a pair of connected pistons and provides increased power and fuel economy. The fuel combustion chamber includes a single-acting air inlet valve and a double-acting outlet valve. The oil cooling system delivers air through each of the pistons whereby the oil is recirculated after cooling.
