A method of preparing a combustible mixture in an internal combustion piston engine and an engine working according to this method.

摘要

A method of preparing a mixture consists in successive performing of: atomization of fuel in a stream of exhaust gases, introduction during suction or an exchange of the load of an incombustible fuel-combustion mixture to a separate storage space, compression - in a positive-displacement manner without mixing - of the mixture with the air inflowing to the storage space from the working space of the engine, forcing through of the compressed mixture into the combustion chamber before the top dead center of the piston completing the compression strike, and in production of a combustible mixture by mixing with air compressed in the combustion chamber.

A piston engine of internal combustion of the mixture produced by the said method utilizes the configuration of a piston (5) and a head (17) separating in the range of the top dead center a combustion chamber (1) and a forcing-through chamber (2). Additionally, it has a storage space (3) connected periodically by a periodically cutting-off mechanism with an exhaust gases passage comprising a device (7) atomizing the fuel. The storage space (3) is shaped so that it connects in a through manner the forcing-through chamber (2) and the combustion chamber (1) separated in the range of the top dead center of the piston. The storage space (3) can be situated in a head (17) or in the head of the piston (5), whereas the cut-off mechanism can be a pressure-controlled non-return valve (6) or directly the piston (5) performing the function of a slotted timing gear in co-operation with passages of the cylinder (16).

The solution can be applied in four-stroke and two-stroke spark-ignition and compression ignition engines.
