Abstract
A fuel injector includes a first input for receiving a fuel and a second input for receiving a non-fuel fluid. The fuel injector also includes a fluid ejector that includes a first drop ejector for discretely ejecting droplets of the fuel, the fluid ejector also including a second drop ejector for discretely ejecting droplets of the non-fuel fluid.
Claims20
A fuel injector, comprising:
- a first input for receiving a fuel;
- a second input for receiving a non-fuel fluid;
- and
- a fluid ejector being configured to include a first drop ejector for discretely ejecting droplets of the fuel, the fluid ejector also being configured to include a second drop ejector for discretely ejecting droplets of the non-fuel fluid.
A fuel injector, comprising:
- a fluid ejector configured to discretely eject fuel and non-fuel fluid in a digital manner;
- wherein
- the fluid ejector includes a first set of firing chambers and a second set of firing chambers, wherein each firing chamber of the first set has a first volume, and wherein each firing chamber of the second set has a second volume.
A method of delivering fuel and non-fuel fluid to a combustion chamber of an internal combustion engine, comprising:
- ejecting discrete droplets of the fuel from a first drop ejector;
- ejecting discrete droplets of the non-fuel fluid from a second drop ejector;
- and
- vaporizing and mixing the discrete droplets of the fuel and the non-fuel fluid.
A method for delivering fuel to a combustion chamber of an internal combustion engine, comprising:
- ejecting discrete fuel droplets from a first drop ejector;
- sensing that the internal combustion engine is operating under a high load condition;
- responsive to the sensing step, ejecting non-fuel fluid droplets from a second drop ejector;
- and
- vaporizing the ejected fuel droplets and the non-fuel fluid droplets.
A fuel consumption device, comprising:
- an internal combustion engine;
- a fuel delivery system coupled to the engine;
- wherein
- the fuel delivery system includes means for delivering discrete droplets of a fuel and means for delivering discrete droplets of a non-fuel fluid substantially simultaneously.
