Title:
INTERCOOLING AND HEAT-REGENERATING TWO-STROKE ENGINE
Document Type and Number:
WIPO Patent Application WO/2004/009977
Kind Code:
A1
Abstract:
The invention discloses an intercooling and heat-regenerating two-stroke engine. The engine includes a main cylinder (14), a compression cylinder (26) and one sub-cylinder (45) or two sub-cylinder (48) and (55), in addition, an intercooler (92) and a heat regenerator are provided to the engine. The sub-cylinder can communicate with a charging port, a scavenging inlet, a scavenging outlet and an outlet for hot gas in turn via a control valve, thereby accomplish the cycle of working process which includes intercooling and heat-regenerating procedure. The outlet (90) for hot gas communicates with the main cylinder (14) via a combustion chamber (100) and a connecting passage (101). The burning will not occur within the sub-cylinder, thereby the heat loss of sub-cylinder can be eliminated, and the corresponding control valve can be free of the high temperature influence from working fuel gas.
