Abstract
The invention relates to an engine having prechamber ignition, in particular a gas engine, that comprises a main combustion space in a cylinder of the engine for combusting an air-fuel mixture and a prechamber having an ignition device arranged therein and a fuel injector arranged therein, wherein the prechamber has at least one transfer port that fluidically connects the prechamber to the main combustion space. The engine is characterized in that the fuel injector arranged in the prechamber is the only fuel injector via which fuel can be introduced into the associated main combustion space.
Claims19
An engine (1) comprising prechamber ignition, in particular a gas engine, comprising:
- a main combustion space (2) in a cylinder of the engine (1) for combusting an air-fuel mixture;
- and
- a prechamber (3) having an ignition device (4) projecting into it and a fuel injector (5) projecting into it,
- wherein the prechamber (3) has at least one transfer point (6) that fluidically connects the prechamber (3) to the main combustion space (2),
- the fuel injector (5) projecting into the prechamber (3) is the only fuel injector (5) via which fuel can be introduced into the associated main combustion space (2), and
- further comprising a valve (7) in a wall (8) separating the prechamber (3) and the main combustion space (2) that provides a selectively additional fluidic connection (10) between the prechamber (3) and the main combustion space (2) beside the at least one transfer point (6).
