Abstract: An electromagnetic fuel ram-injector and improved ignitor.

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.

Abstract: An electromagnetic fuel ram-injector and an improved fuel ignitor are disclosed for independent as well as cooperative use. The injector includes the use of two opposing radially slotted disc armatures attached to a single tubular ram rod to supply fuel to the injector. The ignitor includes the use of heated wire in conjunction with ceramic to provide an ignition source.

Abstract: The invention is a pulsed, hydraulically actuated fuel injector ignitor system for an internal combustion engine with combustion chambers and a fuel injector, comprising an outer shell containing a fuel inlet cavity, a fuel supply and scavenging chamber supplied with fuel from the inlet cavity through the rod bore of the injector rod, and a fuel pressure chamber, which is resupplied through check valve from the supply chamber after each injection has taken place. The pressure chamber has a poppet valve responsive to a predetermined fuel pressure in the pressure chamber, resulting from the intrusion of injector piston into the pressure chamber, thereby spraying fuel into the combustion chamber through a hot-throated venturi and igniting the fuel as it passes through venturi. Concentric open-ended cylinders form the control body assembly and are positioned between the base assembly and the fluid manifold head cap and having alternate open-ended cylinders in communication with sliding contact.

Abstract: In an internal combustion engine with combustion chambers (CC'S) (538), a fuel injector (FI) comprising an outer shell (628) containing a fuel supply cavity (FSC) (530) having an openable valve (546) for storing fuel, a control body assembly (CBA) (520) within the outer shell (628). A rod (512) extends from FSC through CBA along the length of the outer shell with piston (518) formed thereon. An internal bore (534) extends therethrough from the side of a closed end of rod (512) which is movable into the FSC for carrying fuel from the FSC to the CC. A rod supporting base assembly (562), responsive to a predetermined CC pressure increase causes rod (512) to enter FSC, closing valve (546) to cease fuel from entering FSC and exposing bore (534) to force the pressurized fuel in the FSC down bore into the CC. Concentric open ended cylinders (OEC'S) (510) are positioned between the CBA and the base assembly with alternate OEC'S (514) secured to CBA and the other OEC'S (516) secured to base assembly (562).

Abstract: An injector (10) for delivering fuel directly into an engine combustion chamber (11) in response to compression within the combustion chamber (11). The injector (10) has a housing (14) with an injector rod (22) slidably mounted within housing (14). Secured to the injector rod (22) is a primary piston (24), a metering spool (25), and a secondary piston (32). The metering spool (25) is located within a metering chamber (26) having a bypass chamber (50) in which is located two series of electrodes (60 and 62) which are connected to an electrical system which sequentially provides an electrical signal to the connector (56) as dictated by the needs of the engine. As the electrical signal is supplied to connector (56), an electro-rheological fluid (64) contained within the metering chamber (26) is converted from a liquid to a substantially solid condition, thereby limiting the travel of the metering spool (25) and the secondary piston (32).
