Abstract
A two-stroke-cycle engine has a pivoted divider oscillating within a fan-shaped combustion volume. The divider is connected to a connecting rod which is connected to an output crankshaft. Seals are used instead of piston rings. Each of the two radial walls has a spark plug and a fuel injection tube located near the outer end. Each planar parallel side wall has an air inlet port near the inner end. An exhaust port is located in the center of the arcuate wall.
Claims9
A two-stroke cycle internal combustion engine comprising:
- a fan-shaped combustion volume having two flat radial end walls, an arcuate top wall and two flat parallel fan-shaped side walls;
- a single pivoted divider oscillating on a fixed pivot pin, said divider having a first end and a second end, with the first end of said divider oscillating within the combustion volume thereby dividing the combustion volume into two combustion chambers;
- the second end of said pivoted divider being bifurcated;
- a connecting rod having a first end and a second end, with the first end being rotatable on a wrist pin located within the bifurcated end of the pivoted divider;
- a power output crankshaft, to the crank of which the second end of the connecting rod is rotatably attached;
- two spark plugs, with one extending through each radial wall of the fan-shaped combustion chamber;
- two fuel injection tubes, with one extending through each radial wall of the fan-shaped combustion chamber;
- an exhaust port extending through the center of the arcuate top wall of the combustion chamber;
- and
- two air intake ports, with one extending through the center of each of the flat parallel fan-shaped side walls.
