Abstract
Methods and systems are provided for a fuel injector coupled to mixing passages for entraining combustion chamber gases with a fuel injection to decrease formation of soot throughout a range of engine operating parameters. In one example, a method includes decreasing a combustion chamber temperature in response to an amount of sensed light.
Claims20
A system comprising:
- a fuel injector comprising a nozzle tip submerged into a combustion chamber below an end wall of a cylinder head, the nozzle tip comprising one or more fuel injection orifices configured to inject at an angle relative to a central axis of the fuel injector;
- and
- one or more mixing passages configured to receive a fuel injection or combustion chamber gases, where the one or more mixing passages configured to receive the fuel injection are oblique to the central axis and are aligned with the fuel injection orifices, and where there are more mixing passages configured to receive combustion chamber gases than mixing passages configured to receive the fuel injection.
A method comprising:
- decreasing a combustion chamber temperature in response to an amount of light sensed in a passage fluidly coupling a fuel injector to the combustion chamber.
A system, comprising:
- a fuel injector located in a cylinder head;
- a passage located below the cylinder head in a combustion chamber, the passage aligned with a fuel injector orifice of a nozzle of the fuel injector;
- and
- a controller with computer-readable instructions that when implemented allow the controller to:
- decrease a cylinder temperature in response to an amount of light measured by a light sensor in the passage being greater than a threshold amount of light.
