Method for operating a pollution-reducing engine

A method for operating an engine comprising an intake and compression chamber, a constant volume expansion chamber coupled to said intake and compression chamber, an expansion and exhaust chamber coupled to said constant volume expansion chamber, and a reservoir coupled to said constant volume expansion chamber, said intake and compression chamber and said expansion and exhaust chamber having a piston therein connected to a respective crankshaft and a linkage between said crankshafts, said method comprising the step of:

• drawing air into said intake and compression chamber;
• compressing said air drawn into said intake and compression chamber thus raising it to an elevated pressure and temperature;
• transferring said compressed air into said constant volume expansion chamber at said elevated pressure and temperature;
• injecting additional air into said constant volume expansion chamber from said reservoir, thus further increasing said elevated temperature and pressure of said compressed air;
• allowing said compressed air to expand in said expansion and exhaust chamber thus performing physical work;
• and
• exhausting said compressed and injected air out of said engine, wherein, no fuel is supplied to said engine.

A method for operating an air-fuel/air-air dual-mode dual-energy reducing engine without using fuel, the dual-mode dual-energy engine comprising an independent intake and compression chamber connected via a transfer to an expansion and exhaust chamber, an exhaust port, a reservoir for high pressure air and an air injector, said intake and compression chamber and said expansion and exhaust chamber having a piston therein connected to a respective crankshaft and a linkage between said crankshafts, said method comprising the steps of:

• drawing air into said intake and compression chamber;
• compressing said air drawn into said intake and compression chamber thus raising it to an elevated pressure and temperature;
• tansferring said compressed air into a constant volume expansion chamber at said elevated pressure and temperature;
• injecting additional air into said constant volume expansion chamber from said reservoir, thus further increasing said elevated temperature and pressure of said compressed air;
• allowing said compressed air to expand in said expansion and exhaust chamber thus performing physical work;
• and
• exhausting said compressed and injected air out of said engine;
• wherein no fuel is supplied to said engine.
