Abstract:
1. A radial two-stroke, uniflow, internal combustion (IC) engine including a plurality of cylinders arranged radially around a common engine axis, each cylinder including: a cylinder wall and a cylinder head having an exhaust port, an exhaust valve disposed in the exhaust port, a fuel injector and a spark means disposed through the cylinder head, a piston mounted in the cylinder for reciprocal movement between a top dead center (TDC) position and a bottom dead center (BDC) position, and through a compression stroke and a power stroke, at least one swirl inlet port passing through the cylinder wall at the bottom of the cylinder, the at least one swirl inlet port oriented tangential to an axial centerline of the cylinder, wherein the at least one swirl port is covered and uncovered in response to the reciprocal movement of the piston; and further including a high pressure inlet air compressor that discharges to an inlet air manifold, an annular exhaust air manifold in exhaust gas communication with each exhaust port, and an exhaust-driven radial in-flow turbine that drives the air compressor.
