Abstract
2-Stroke engines normally run dirty and exhaust a significant amount of unburnt gas, which is Typically addressed by specially designed exhaust systems. These redirect the pulses of the engine back into the combustion chamber to push some of the unburnt fuel back into the engine. But this only fixes the problem for a narrow range of the 2-stroke’s operation. Our solution would instead remedy the natural inefficiency of a 2-stroke engine by igniting the unburnt fuel in a second combustion chamber which would then power a turbo-compressor on the 2-stroke engine. This would theoretically allow the 2-stroke engine to be much more efficient for its entire operating range. Which would make it more power dense, while also reducing the emissions of the engine.
