ABSTRACT:
A compression-ignition internal combustion engine for aircraft generally comprises a stationary crankshaft, a crankcase adapted to rotate about the stationary crankshaft, and a plurality of cylinders radially extending from the crankcase. Each cylinder includes a piston adapted to reciprocate therein and a connecting rod drivingly coupling the piston to the crankshaft. The engine further comprises a valve assembly for operating an exhaust valve associated with each cylinder and a fuel assembly for supplying fuel to each cylinder. First and second cams mounted on the crankshaft are adapted to operate the valve assembly and fuel assembly in a timed manner as the crankcase rotates about the crankshaft. The engine also includes a propeller synchronizer for adjusting the pitch of a plurality of propellers radially extending from the rotating crankcase.
