Abstract
The disclosure relates to a fuel injection and combustion system in an internal combustion engine, comprising: a main injector comprising at least one main injector outlet configurable to direct a volume of fuel therethrough; a side injector comprising a side injector outlet configurable to direct a volume of fuel therethrough and in a direction towards the main injector; a glow plug positioned between the main injector and the side injector outlet and configurable to provide an increase in temperature so as to ignite a volume of fuel from the side injector outlet and subsequently a volume of fuel from the at least one main injector outlet. The disclosure further relates to a method for injecting and combusting fuel in an internal combustion engine.
Claims19
A fuel injection and combustion system in an internal combustion engine, comprising:
- a main injector comprising at least one main injector outlet configurable to direct a volume of fuel therethrough;
- a side injector comprising a side injector outlet configurable to direct a volume of fuel therethrough and in a direction towards the main injector, wherein the side injector is configurable to direct a volume of fuel at a centroid of the main injector;
- and
- a glow plug positioned between the main injector and the side injector outlet and configurable to provide an increase in temperature so as to ignite a volume of fuel from the side injector outlet and subsequently a volume of fuel from the at least one main injector outlet.
A method for injecting and combusting fuel in an internal combustion engine, comprising:
- injecting a first volume of fuel from an outlet of a side injector in a direction of a main injector, wherein the side injector is configurable to direct a volume of fuel at a centroid of the main injector;
- injecting a second volume of fuel from at least one outlet of the main injector;
- providing an increase in temperature of a glow plug positioned between the side injector and the main injector;
- and
- igniting the first volume of fuel and subsequently igniting the second volume of fuel.
