Internal Combustion Engine with Integrated Air Compressor

A piston-cylinder arrangement for an internal combustion engine, the arrangement comprising:

• a first cylinder bore in an engine block, the first cylinder bore having an axis extending along a length of the first cylinder bore;
• a first piston positioned within the first cylinder bore for reciprocation along the axis;
• a combustion chamber positioned between walls of the first cylinder bore and the first piston;
• an inlet for directing intake contents into the combustion chamber;
• an outlet for directing exhaust contents of the combustion chamber out of the combustion chamber;
• a second cylinder bore in the engine block, the second cylinder bore aligned with the first cylinder bore along the axis;
• a second piston positioned within the second cylinder bore for reciprocation along the axis;
• a compression chamber positioned between walls of the second cylinder bore and the second piston;
• one or more ports in the engine block for directing air into and out of the compression chamber;
• and
• one or more supporting members connecting the first piston to the second piston, the one or more supporting members positioning the first piston and the second piston is a spaced apart relationship for facilitating concurrent reciprocation of the first piston and the second piston within their respective cylinder bores during operation of the internal combustion engine;
• wherein the first piston, the second piston and the one or more supporting members define a stacked piston arrangement.
