Internal ram fuel delivery

Abstract

The Internal Ram Fuel Delivery (IRFD) is a means for utilizing the movement of a reciprocating piston within an internal combustion engine, in conjunction with a secondary piston, or ram, to deliver fuel in the form of a liquid, gas, or an air mixture into a combustion chamber. The two most likely configurations of the IRFD involve either: a ram attached to an engine's primary piston(s) that travels inside a stationary ram cylinder attached to the top of the primary piston's cylinder head, with controlled fuel pathways; or, a ram cylinder attached to, or housed inside of the engine's primary piston(s) which travels on a stationary ram that is attached to the top of the primary piston's cylinder head, with controlled fuel pathways; whereby, the ram and ram cylinder move relative to one another when the engine's primary piston reciprocates, creating a pumping effect that can deliver fuel into a combustion chamber at a predetermined point during the primary piston's travel.
