Patent DE-19843567-A1 (DE)
Inventor: TOMCZYK HUBERT
IPC: F02B75/02
Filed: 1998-09-23
Abstract: The invention relates to an operating method of an internal combustion engine. According to said method, a fuel-air mixture is rapidly combusted in order to move a piston (3). The fuel contained in or introduced into an occluded fresh gas is evaporated in said fresh gas, which has already been sucked into a cylinder chamber (12) and then compressed. The fuel is then combusted and the piston is subjected to the pressure produced by the combustion gases (working cycle). After performing its working cycle, the piston ejects the waste gases from the cylinder chamber (12). The aim of the invention is to improve the efficiency of the internal combustion engine. To this end, the fresh gas that is compressed during the compression cycle is pressed into a first combustion chamber (13). The aforementioned evaporation process is then carried out in said first combustion chamber once it has been sealed off from the cylinder chamber. The aforementioned combustion process then begins, and at the same time, a second combustion chamber (14), which is sealed all around prior to this stage, opens to the cylinder chamber (13) and the piston (3) is subjected to the action of the combustion gases which have been produced as before and which expand out of the second combustion chamber, so that it can perform its working cycle. As a result, in each compression cycle, one of the two combustion chambers (13, 14) is filled alternately and for each subsequent working cycle, the piston is impinged upon from the other of the two combustion chambers (13, 14).
