A recycling system for linear motors includes a dual piston within a cylinder housing that is moved from an upper position to a lower position by combustion pressure such that a first portion of the piston pumps compressed air from a first air chamber within a first bore of the cylinder housing and a second portion of the piston pumps compressed air from a second air chamber within a second larger bore of the cylinder housing. An exhaust valve is opened by the compressed air for venting the combustion chamber to atmosphere. The dual piston moves within the cylinder housing from the lower position to the upper position assisted by the compressed air such that a portion of the volume of the combustion chamber is converted into a portion of the volume of the second air chamber. A control valve is opened in response to movement of the dual piston through the upper position for allowing airflow from the second air chamber into the combustion chamber.
