An improved, internal combustion, reciprocating engine employs thermal regeneration to improve its efficiency and power. Regeneration is accomplished through the use of an alternating flow heat exchanger. In one embodiment the engine consists of one or more cylinders (10) containing a pair of opposed pistons (12,112,14,114), a hot piston (14,114) and a cold piston (12,112) separated by a stationary regenerator (28,128). The engine is equipped with means to introduce gaseous or liquid fuel into said hot volume (32,132), means to introduce fresh working fluid and means to remove exhaust gases from the cold volume (30,130). In one embodiment one or more exhaust ports (40,140) permitting the flow of exhaust fluid out of the cylinder (10) are located between a cold piston (12,112) and the thermal regenerator (28,128) and one or more intake ports (38,138) permitting the flow of fresh working fluid into the cylinder (10) are located between the cold piston (12,112) and the exhaust ports (40,140). The engine can provide greater expansion than compression and can provide critical and substantial improvements over previous engines. |
