Two-stroke uniflow turbo-compound internal combustion engine

摘要

A radial, two-stroke uniflow internal combustion (IC) cylinder and multiple cylinder engine, the cylinder having a cylinder wall and a cylinder head, the cylinder head having an exhaust port, a fuel injector, and a spark means disposed through the cylinder head, a piston reciprocally mounted in the cylinder for movement alternately through compression and power strokes, and an inlet swirl port disposed through the cylinder wall providing fluid communication into the cylinder chamber, and having an annular exhaust air manifold in exhaust gas communication with each exhaust ports, and an exhaust-driven radial in-flow turbine that drives the inlet air compression.

主权项

1. A radial two-stroke, uniflow, internal combustion (IC) engine including a plurality of banks of cylinders arranged along a common drive shaft, each bank of cylinders comprising a plurality of radially-arranged cylinders, 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 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 high pressure inlet air compressor.
