摘要:
A cover for a battery module having a plurality of battery cells arranged in a stacked configuration includes a non-conductive main body having a plurality of spaced apart recessed regions formed therein and a plurality of electrically conductive connectors, each of the connectors disposed in one of the recessed regions and coupled to the main body.

A dual-purpose engine fitting is provided that may be used both during engine testing and during engine use, for vehicles with vacuum assisted brakes and for those without. The fitting has a body portion configured to fit within an opening in the manifold and defining a passage having opposing first and second ends. The fitting has a seal portion enclosing the first end of the passage. The second end of the passage is open to the manifold when the body portion is fit within the manifold. A thinned wall joins the body portion and the seal portion, establishing a predetermined fracture region at which the seal portion will separate from the body portion when sufficient torque is applied to the seal portion to thereby open the first end of the passage. A method of assembling vehicles is also provided.

A fuel system for use on an internal combustion engine has a fuel metering body which defines a fuel plenum therein. The plenum has an inlet for pressurized fuel, a pressure regulator, and a fuel outlet. Disposed within the fuel plenum, in fluid communication with one another, the inlet and the outlet, are a plurality of fuel injectors. The fuel injectors have outlets which extend through the fuel meter body and deliver fuel to the intake ports of the associated engine through flexible fuel lines terminated by pressure pulse activated poppet nozzles providing a significant degree of application flexibility. The fuel meter body mounts within the intake manifold such that fuel and electrical connections extend out of the manifold for simplified source attachment.

In a throttle body fuel injection assembly, the rotor of a throttle position sensor is mounted directly on the throttle shaft and the sensor housing is supported on the rotor, thereby providing a compact sensor construction. A spring in the sensor tends to impart relative rotation between the rotor and the housing, biasing the housing toward engagement with the throttle body. With this invention, the housing rotates with the rotor away from engagement with the throttle body if the spring does not impart relative rotation between the housing and the rotor.
摘要:
A fuel cell stack that includes a non-permeable shim plate positioned between a composite unipolar plate and a terminal plate at both ends of the stack, where the shim plate is made of a non-corrosive material, such as stainless steel, titanium or sealed graphite. Because the shim plate is non-permeable, it prevents cooling fluid that diffuses through the unipolar plate from contacting the terminal plate, which would otherwise corrode the terminal plate. The shim plate can be coated with a conductive material, such as gold, platinum, ruthenium oxide or mixtures thereof, to reduce its contact resistance.
摘要:
An integrated intake manifold assembly including a first poppet valve assembly disposed at the manifold air inlet to regulate air flow into the manifold; a second poppet valve assembly disposed on the manifold to regulate exhaust gas flow into the air intake system; and a bi-directional camshaft with cams for operating simultaneously the manifold vacuum regulating valve and the exhaust gas recirculation valve. The valve bodies are integrally formed in the wall of the intake manifold. The cams are arranged on the shaft to provide optimum synchronized opening and closing of the related valves. When used on a diesel engine, the manifold assembly may further include a swirl valve plate disposed between the manifold and the engine head and having a plurality of ganged swirl valves actuated by levers, connected to the camshaft internally of the manifold and swirl plate, for coordinated motion with the MVR and EGR valves.

The valve poppets of the MVR and EGR valves are actuated by finger followers actuated by the camshaft to eliminate side loading of the valve stems.
