Abstract: The present invention allows the air-fuel mixture to swirl in a combustion chamber to increase the power from the engine. Each engine cylinder contains a piston, a combustion chamber, and at least one intake valve, exhaust valve, and spark-plug. Also, the top of the piston head contains a hole that forms the entry point of a converging nozzle, where the air-fuel mixture is first directed downwards and then horizontally through intake nozzles onto ramps located on the inner walls of the combustion chamber that allows the air-fuel mixture to swirl in a counter-clock wise motion. This swirling effect causes a cyclone inside the combustion chamber that when ignited it results in an additional explosive force that drives the piston downwards with additional acceleration, which increase the power produced by the engine.
