Claims12
A system, comprising:
- a pre-chamber fluidly coupled to a primary combustion chamber, the pre-chamber comprising a connecting passage fluidly coupling a fuel injector to the pre-chamber outside of the primary combustion chamber, wherein the fuel injector is the only fuel injector and is positioned to inject fuel directly into the primary combustion chamber and the connecting passage.
An engine, comprising:
- a pre-chamber fluidly coupled to a primary combustion chamber, wherein a piston is configured to oscillate within the primary combustion chamber, wherein the pre-chamber comprises an air passage fluidly coupling the pre-chamber to an intake passage, wherein the air passage is arranged outside of the primary combustion chamber, and wherein the pre-chamber further comprises a connecting passage configured to couple the pre-chamber to a fuel injector positioned to inject directly into the primary combustion chamber and the connecting passage, wherein the fuel injector is the only fuel injector and where the connecting passage is arranged outside of the primary combustion chamber.
