Regenerative Internal Combustion Engine: 5,499,605

A regenerative internal combustion engine (10) is provided that includes a regenerator (65) that is capable of preheating a charge of compressed air, while not causing premature combustion of fuel. The regenerator (65), in combination with a catalyst (75), also ignites residual amounts of combustible material in exhaust gases. The catalyst (75) itself is capable of oxidizing fuel in a combustion cylinder (50) once stable combustion is achieved.
