ROTARY INTERNAL COMBUSTION ENGINE WITH PILOT SUBCHAMBER AND METHOD OF INJECTING FUEL

A Wankel engine (10) has an insert (34) in the peripheral wall of the stator (18). The insert (34) is made of a material having a greater heat resistance than that of the peripheral wall (18) and has a subchamber (72) defined therein and an inner surface (66) bordering the engine cavity (20). The su...

Beschreibung
Zusammenfassung:	A Wankel engine (10) has an insert (34) in the peripheral wall of the stator (18). The insert (34) is made of a material having a greater heat resistance than that of the peripheral wall (18) and has a subchamber (72) defined therein and an inner surface (66) bordering the engine cavity (20). The subchamber communicates with the cavity (20) through at least one opening (174), which is defined in the inner surface (66) and has a shape forming a reduced cross-section adjacent the opening (74). A pilot fuel injector (78) has a tip (80) received in the subchamber (72). An ignition element (84) has a tip (86) received in the subchamber (72). A main fuel injector (42) extending through the peripheral wall (18) and has a tip (44) communicating with the cavity (20) at a location spaced apart from the insert (34).
