摘要

An intercooled recuperative internal combustion engine with a four stroke main cylinder comprises a main cylinder (36) having a gas inlet valve and a gas outlet valve (5, 10), a secondary cylinder (62) in communication with the main cylinder (36) and with a heat recuperator (80) via different valves, and a small secondary cylinder (85) in communication with the heat recuperator (80) and with an intercooler (28) via different valves, wherein a gas outlet check valve (23) communicating to the intercooler (28) is provided on the cylinder head (2) of the main cylinder, with the gas outlet check valve being pushed onto a valve seat (24) having a vent hole (25) by a spring at the back thereof. In front of the gas outlet check valve (23), a gas blocking valve (15) having an identical structure to that of the gas inlet/outlet valves is provided, a valve stem (16) of the gas blocking valve passes through the centre of the valve seat (24) and a gas isolation sleeve (26) thereon, and is controlled by a gas blocking cam (17) on the cylinder head (2) in such a way that the gas blocking valve (15) is opened after a compression process caused by the moving up of a piston (38) in the main cylinder (36), and is closed when the piston reaches its top dead point; after the gas blocking valve (15) is closed, a lift valve (44) between the secondary cylinder (62) and the main cylinder (36) is controlled to open, while a gas distribution piston (65) in the secondary cylinder is also moved to a set position a certain distance away from its top dead point, and the lift valve (44) is closed when the gas distribution piston (65) reaches its top dead point. By utilizing the intercooled recuperative internal combustion engine with a four stroke main cylinder, the heat effiency of the internal combustion engine can be increased.
