Abstract
An electromagnetic fuel ram-injector and improved igniter apparatus, comprising a fuel injector, and a fuel igniter in series with the injector, to ignite fuel passing through the injector.
Claims20
A fuel ram assembly for providing fuel to a combustion engine, said fuel ram assembly comprising:
- a body defining an internal chamber and an inlet and an outlet port;
- a ram configured for back-and-forth movement within a portion of said internal chamber;
- and
- a plurality of valves and defined passageways within said internal chamber, said valves and passageways configured such that fuel flow exits said outlet port during said back movement of said ram and also exits during said forth movement of said ram,
- such that flow is directed from said outlet port of said fuel ram assembly no matter what the stroke direction of the ram.

A fuel ram assembly for providing fuel to a combustion engine, said fuel ram assembly comprising:
- a body defining an internal chamber including an upper chamber portion, a lower chamber portion, side channels connecting said upper and lower chamber portions, and an inlet and an outlet port;
- a ram configured for back-and-forth movement within a portion of said internal chamber;
- and
- a plurality of valves within said internal chamber, said valves and passageways configured such that fuel flow exits said outlet port from said lower chamber during said back movement of said ram and also exits during said forth movement of said ram,
- such that flow is directed from said outlet port of said fuel ram assembly no matter what the stroke direction of the ram.

- a plurality of valves within said internal chamber, said valves and passageways configured such that fuel flow exits said outlet port from said lower chamber during said back movement of said ram and also exits during said forth movement of said ram;
- and
- ram controlling circuitry which allows for control of said ram such that said ram may be stroked less during an idle mode or may be stroked more during a higher power need,
- such that flow is directed from said outlet port of said fuel ram assembly no matter what the stroke direction of the ram.

- and
- ram controlling circuitry which allows for control of said ram such that said ram may be incrementally stroked less during an idle mode or may be stroked more during a higher power need,
- such that flow is directed from said outlet port of said fuel ram assembly no matter what the stroke direction of the ram.
