Title: Multicylinder two-stroke internal combustion engine with rotary distributor

Abstract: A multicylinder two-stroke internal combustion engine has a plurality of reciprocating pistons arranged in a circle about a central cavity in which is located a rotary distributor driven in timed sequence with operation of the pistons. The rotary distributor includes internal cavities which may connect through ports in its outer cylindrical surface with the working cylinders to control the flow of intake air, scavenging air and/or fuel to the working cylinders. Scavenging air can be precompressed either in a preceding cylinder, taken in ignition order, or in the crank chambers beneath the pistons.
