Abstract
A device and method for conditioning and/or volumetric heating fuel within an intermittent combustion engine in order to enhance fuel combustion and emission performance is provided. Such a device can include a fuel injector configured to eject a fuel spray having a trajectory within a combustion chamber, an energy source capable of emitting electromagnetic energy, and an optical fiber configured to transmit electromagnetic energy emitted from the energy source into the combustion chamber, and is also configured to cause fuel conditioning.
Claims48
A fuel conditioning device, comprising:
- a fuel injector configured to eject a fuel spray along a trajectory within a combustion chamber;
- an energy source capable of emitting electromagnetic energy;
- and
- an optical fiber coupled to the energy source, wherein the optical fiber is configured to transmit electromagnetic energy emitted from the energy source into the combustion chamber, and is configured to be concentrated and cause fuel conditioning at the fuel spray along the trajectory.
A fuel conditioning device, comprising:
- a combustion chamber;
- a fuel injector configured to eject a fuel spray along a trajectory within the combustion chamber;
- an energy source capable of emitting electromagnetic energy;
- an energy directing member configured to direct the electromagnetic energy to a region along the trajectory to cause fuel conditioning at the fuel spray;
- and
- a rigid housing coupled to the combustion chamber or the fuel injector which houses the electromagnetic energy emitted from the energy source prior to entering the combustion chamber.
A method of conditioning fuel, comprising:
- a) injecting a fuel spray along a trajectory within a combustion chamber;
- and
- b) directing electromagnetic energy from an optical fiber into the combustion chamber, said electromagnetic energy configured to be concentrated and cause fuel conditioning at the fuel spray along the trajectory.
