Abstract: The present invention describes a deflector clip (200) for a fuel injector (100) in an internal combustion engine. The deflector clip (200) has a clip portion (205) and a deflector portion (210). The clip portion (205) has a fixed arm (270) and an adjustable arm (265), which form a slot (275) for mounting the deflector clip (200) onto the fuel injector. The deflector portion (205) deflects the hydraulic fluid draining from the fuel injector. The deflector clip (200) is design to fit any fuel injector having a tolerance within the minimum and maximum tolerances for a fuel injector. In an alternate embodiment, several deflector clips (200) are arranged in a deflector clip assembly (400, 500) having a wiring harness (402, 502) for the fuel injection system.

Abstract: A mounting bracket for mounting an aerodynamic fairing to a truck roof includes a base plate appropriately configured to seat on the roof within the fairing and a fairing engaging face having mounting holes which is oriented when the bracket is mounted to the roof to engage the interior side of the fairing. Depending from the face is a tongue terminating in an outturned tab upon which a bottom edge of a fairing may be seated to establish the appropriate desired clearance between the fairing and the underlying cab roof surface. The tab also serves as a locating member over which a template may be appropriately positioned to indicate the position of the mounting holes in the face of the bracket so that properly aligned cooperating holes may be drilled through the fairing from the exterior surface thereof to permit mounting bolts to attach the fairing to the bracket and the roof.

Abstract: A fuel tank mounting and protective cage for vehicles such as school buses including side structures and a bottom shelf structure, each of these structures being weldments constructed of low carbon, high strength steel tubing having rectangular cross-sections. The bottom structure is connected to the side structures by bolt assemblies, preferably disposed in laterally offset parallel rows, to produce stiff joints between the sections with the result that there is less rotation and localized deformation of the protection cage in the event of an accident. Hold down devices are carried by the bottom shelf structure for securing the fuel tank directly to the bottom shelf structure so that the bottom shelf and fuel tank may be removed as a unit for service.

Abstract: A wastegate actuator control valve for a wastegate of a turbocharger of an internal combustion engine is disposed in the intake manifold pressure supply line to the wastegate actuator and has a spring-biassed piston preventing intake manifold pressure from being transmitted through said line until a predetermined intake manifold or boost pressure is reached. The valve housing also has a bleed orifice communicating to the atmosphere to relieve any residual pressure in the actuator when the valve is closed but which bleed orifice is closed upon the piston moving to the open position. Such residual pressure relief results in the full preload of the actuator spring being exerted to completely close the wastegate. Further, the piston is provided with a metering orifice through which the intake manifold pressure flows to the wastegate actuator.

Abstract: An exhaust back pressure control system includes a valve in the exhaust outlet of a turbocharger of an internal combustion engine which is controlled by an engine control microcomputer. When the valve is moved toward a closed position, it restricts the exhaust flow, thereby increasing back pressure and friction within the engine by producing an artificial load thereon, and thus speeds up the warming process taking place within the engine upon starting thereof. The valve is moved by an actuating piston within a hydraulic cylinder using engine oil pressure controlled by an electrically operated valve receiving a pulse width modulated operating signal from the engine microcomputer, the operating signal being generated to provide a desired back pressure as a function of engine coolant temperature, engine speed, engine fuel comsumption, and actual back pressure. Operation of the system is enabled if the ambient air temperature is below 2.degree. C.

Abstract: A relatively thin, post-mounted valve lever having a ball bearing pivot for operating an intake or exhaust valve of an internal combustion engine and having a lateral bearing surface which slidably engages aligned spaced lateral surfaces on a wide supporting post which maintain the rocking plane within the valve lever. A retainer is disposed on the top side of the post and extends into the central opening in the valve lever to prevent the rocker arm, post, and ball bearing from becoming disassembled.

Abstract: An electronic module interfaces a microcomputer with the fuel injection equipment of a diesel engine so that the microcomputer, acting through the module, exercises control over the fuel injected into the engine. A pulse width modulated fuel deliver control signal issued by the microcomputer is transmitted through the module to energize a proportional solenoid actuator that positions the fuel rack. Rack position is sensed by an eddy current sensor that provides feedback through the module to the microcomputer so that the rack position is closed-loop controlled. The sensor has a measurement coil for measuring rack position and a reference coil for temperature compensation. The two coils are connected in a circuit of the module that produces a pulse width modulated feedback signal which is supplied to the microcomputer in synchronism with the fuel deliver control signal. This latter circuit comprises an L/R monostable for each coil and pulse stretchers that stretch the output pulses from the monostables.
