Integrated fuel injectors and igniters and associated methods of use and manufacture
First Claim
1. A fuel injector-igniter sized to receivably engage a standard spark plug connection and configured to reduce fuel dribble during fuel delivery, comprising:
- a fuel injector-igniter for injecting fuel and igniting fuel, the fuel injector-igniter includes a body having a middle portion extending between a base portion and a nozzle portion;
the nozzle portion is configured to engage a standard spark plug connection in a fuel combustion engine, the body having a channel configured to allow fluid passage extending there through;
a first and a second electrode configured to provide a ignition event, the first and the second electrode positioned at a distal end of the nozzle portion;
an actuator contained within the channel of the injector-igniter body, the actuator having a distal end and a proximal end;
a flow control device fluidically coupled to the channel and operably connected to a distal end of the actuator wherein the flow control device includes a mechanical check valve;
a driver operably connected to a proximal end of the actuator; and
a controller operably connected to the driver, the controller configured to adaptively optimize the fuel injection and ignition characteristics of the injector-igniter.

Abstract
The present disclosure is directed to injectors with integrated igniters providing efficient injection, ignition, and complete combustion of various types of fuels. These integrated injectors/igniters can include, for example, insulators with adequate mechanical and dielectric strength to enable high-energy plasma generation by components that have very small dimensions, multifunction valving that is moved to injector multiple bursts of fuel and to induce plasma projection, a fuel control valve at the interface to the combustion chamber for the purpose of eliminating fuel drip at undesired times, and one or more components at the interface of the combustion chamber for the purpose of blocking transmission of combustion sourced pressure.
