Abstract (en)
[origin: FR2846042A1] An ignition system for an internal combustion engine comprises: (a) a main combustion chamber (1) destined to contain a main fuel mixture, and equipped with a compression system; (b) an ignitor (11) incorporating a precombustion chamber (2) destined to receive some reactives and an ignition system (13, 14) for the reactives contained in the precombustion chamber; (c) the precombustion chamber is defined by a body (12) having a head (12a) incorporating at least one passage (15); (d) the head separates the precombustion chamber from the main chamber, which are connected by passages in the head; (e) the body of the precombustion chamber is made in a material with a thermal conductivity at 20 degrees Celsius of at least 10 W/K/m. An Independent claim is also included for an ignitor for an internal combustion engine incorporating a precombustion chamber.
