Abstract: A fuel supply system (10) for a vehicle includes a fuel tank (12) for holding fuel therein. A pump (14) pumps fuel from the tank. A filter (16) filters fuel. A fuel rail (20) receives filtered fuel originating from the pump. A pressure regulator (18) controls pressure of fuel received by the fuel rail. Fuel injectors (24) inject fuel, received from the fuel rail, into an internal combustion engine. A fuel detection system (28) in in the fuel supply system and includes a plurality of detectors (30, 30?). Each detector is constructed and arranged to be exposed to fuel to detect a distinct chemical element or compound in the fuel.

Abstract: An orifice disc for a fuel injector includes two orifices that provide a desired interaction between two fuel flows to increase fuel atomization and improve combustion performance. The orifice disc includes a first orifice and a second orifice that are disposed at an interaction angle relative to each other. The orifices are orientated relative to each other such that fuel flow exiting the outlets impinges on each other to further reduce the size of fuel droplets. Large dramatic changes in momentum caused by the impingement of fuel flows disintegrates fuel droplets into much smaller finer fuel droplets that provided enhanced atomization.

Abstract: The coil of a solenoid-operated valve is fluid-isolated from fluid whose flow is controlled by the valve by providing the solenoid with an imperforate transverse end wall having a radially inner annular ferromagnetic zone forming one portion of the stator, a radially outer annular ferromagnetic zone forming another portion of the stator, and a radially intermediate annular zone of non-magnetic material separating the radially inner and radially outer ferromagnetic zones.

Abstract: In a fuel injector, a swirl generator operates to impart a tangential or swirl component to the fuel as it is expelled from the injector. The mass of the swirl generator is minimized so as to maximize the actuating speed of the injector. The swirl generator develops a pressure drop across the generator during the time the fuel is expelled which pressure drop aids in enhancing the closure time of the injector. The swirl generator provides damping to the needle valve upon both opening and closing. The swirl generator minimizes the volume of residual fuel remaining in the injector.

Abstract: A fluid motor (10) having a housing (12) with first (14), second (16) and third (18) chambers therein. A first partition (22) separates the first chamber (14) from the second chamber (16). A second partition (24) separates the second chamber (16) from the third chamber (18). The third chamber (18) is connected to a source of fluid under pressure. A valve mechanism (91) controls the communication of the source of fluid between the second (16) and third (18) chambers. A poppet valve (42) allows the fluid to flow into the first chamber (14) from the second chamber (16). The first chamber (14) is connected to the third chamber (18) through a check valve (118). The valve mechanism (91) responds to an operator input signal by terminating fluid communication between the second (16) and third (18) chambers and initiating communicationof the second chamber (16) with the atmosphere to allow fluid to escape and create a pressure differential across the first (22) and second (24) partitions.

Abstract: A control valve for a servomotor having a disc located in a bore of a hub attached to a movable wall. The movable wall separates a first chamber from a second chamber. A passage in the disc connects a first passageway with a second passageway in the hub to define a flow path to allow free communication of a first fluid between the first and second chambers. A plunger located in the bore has a first end with an axial projection extending therefrom which engages the disc and a second end connected to an input push rod. An input force applied to the push rod moves the plunger which causes the axial projection to deform the disc and interrupt the flow path between the first and second chambers. Thereafter, further movement of the plunger allows a second fluid to be communicated to the second chamber whereby a pressure differential is created across the wall by the first and second fluids. The pressure acting on the wall creates a force which moves the wall and provides an output member with an operational force.
