Principles Of Operation


The PowerLite-100 is a twin cylinder opposed piston engine that has two pistons in each cylinder with the combustion chamber formed between the crowns of the pistons.  During compressions the pistons meet near the center of the cylinder, the air is compressed, fuel is injected and combustion occurs.

Combustion drives the pistons outwards driving the crankshafts and through the synchronized gear train produces power to centrally located output drive.  Being a two-stroke, the engine does not have mechanically operated valves but instead the cylinders are ported.  Piston movement reveals ports at each end of the cylinder; one side is intake, the other is exhaust.  This configuration eliminates the need for a cylinder head, camshaft and associated valve train components.

Gas flow through the cylinder is in one direction and promotes a more efficient cylinder gas scavenging than is normally achieved in a conventional two-stroke engine.  A centrifugal compressor positively pressurizes the intake air on the PowerLite-100.  This supercharging improves the scavenging process and slightly boosts engine power.
