Document Type and Number:
WIPO Patent Application WO2004036013
Kind Code:
A8
Abstract:
The invention concerns an ignition device for an internal combustion engine comprising: a main combustion chamber (1) provided with a compression system, and an igniter (11) including a precombustion chamber (2) and an ignition system (13, 14), the precombustion chamber being defined by a precombustion chamber casing (12) having a head (12a) including passageways (15), the head (12a) of the precombustion chamber casing (12) separating the precombustion chamber (2) from the main chamber (1) and communicating the precombustion chamber (2) with the main chamber (1) via the passageways (15). The invention is characterized in that the passageways comprise at least one passage for propagating a flame front of the precombustion chamber (2) to the main chamber (1) when the engine is running at low charge and at least one passage not allowing propagation of a flame front while allowing passage of unstable compounds of the precombustion chamber (2) to the main chamber (1).
