DEVICE AND METHOD FOR IGNITING AN INTERNAL COMBUSTION ENGINE AND CORRESPONDING SEPARATING WALL

摘要

The invention concerns a device and a method for igniting an internal combustion engine and a corresponding separating wall. The ignition device comprises a main chamber (1) provided with a system for compressing a main fuel mixture and a precombusiton chamber (2) provided with an ignition system (21-22). The precombustion chamber and the main chamber communicate through passages (4a-4d) which prevent a flame front from passing through and allow unstable compounds (31) derived from the burning of reagents contained in the precombustion chamber through. The compression system and the seeding of the main mixture with unstable compounds provide mass self-ignition to the main mixture.
