DIRECT INJECTION AND PRECOMBUSTION CHAMBER SPARK INTERNAL COMBUSTION ENGINE, IGNITION METHOD AND APPLICATION

摘要

The invention concerns an internal combustion engine with at least an engine component, the engine component comprising a combustion chamber (4) for a fuel mixture including fuel and oxidant constituents provided with a compression system (9), a system for igniting (7) the fuel mixture with an igniter, sequential passageway devices for the fuel and oxidant constituents and for the combustion products. The invention is characterized in that the ignition system comprises a substantially spherical closed head (6) (12a) enclosing the igniter in a precombustion chamber, the head including a plurality of orifices (5) for communicating the combustion chamber with the precombustion chamber so that the fuel mixture can pass into the precombustion chamber, and at least one of the passageway devices is a direct injector in the combustion chamber for part of or all the fuel and/or oxidant constituents. The invention also concerns a method and an application.
