Abstract: An improved fuel economy device computes a filtered rate of change of instantaneous fuel economy or a filtered instantaneous fuel economy and repetitively updates a graphical display depicting the current fuel economy. The fuel economy can be displayed as a percentage of a target fuel economy, programmed by the driver or other operator of the vehicle.

Abstract: A combination table and storage unit for use in a truck cab having a base, a substantially planar table, a table storage receptacle coupled to the base providing a sleeve for receiving the table, and a table support. The table support is positionable against one side of the table to allow it to be placed conveniently in the sleeve, yet when needed for support is swung to a position at a substantial angle relative to the table. The unit further includes a removable storage unit which may be releasably attached to the base with defined compartments therein for holding materials needed by the truck operator.

Abstract: A vehicle extender includes a flexible flap supported by a metal extender for closing the gap between the cab and trailer or between trailers of a semi-trailer truck. The flap and extender are preferably coupled together to permit these components to expand and contract relative to one another so that the flap resists buckling. In one preferred approach, the flap is slidably coupled to the extender, although a fastener may be used to hold the flap in place. In a specific form, the extender and flap have mating edges which are configured to engage one another. In another embodiment, the flap is indirectly coupled to the extender by a support.

Abstract: A fuel system has a fuel tank with a wall and a fuel delivery outlet through which fuel is delivered to the engine. The fuel tank has a fuel suction tube extending from the fuel delivery outlet into the fuel tank. Fuel is drawn to the engine from the fuel tank through the suction tube and the fuel delivery outlet. The fuel tank has a fuel cooling return inlet through which unused fuel warmed by the engine may be returned to the fuel tank and cooled. A fuel cooling conduit is coupled to the fuel cooling return inlet. The fuel cooling conduit has at least one fuel dispersing outlet through which fuel is dispersed onto the fuel tank wall to cool the fuel. A fuel warming return inlet is provided through which unused fuel warmed by the engine may be directed to flow adjacent the suction tube to heat the fuel being delivered through the suction tube to the engine. A shroud may also be provided to blend returning warm fuel with cooler fuel from the fuel tank that is flowing toward the suction tube.

Abstract: The throttle breakover apparatus has a cable with one end coupled to an accelerator pedal and a second end terminating in a cable stop. The cable second end is slidably coupled to an engine throttle lever at a position inward from the cable stop. A sleeve surrounds the cable and extends from the cable stop through the throttle lever. A coil spring surrounds the sleeve and is positioned between the throttle lever and the cable stop. A spring guide guides the motion of the coil spring. In response to the depression of the accelerator pedal, the throttle cable first pivots the throttle lever to a full throttle position. Once full throttle is reached, the coil spring is compressed between the cable stop and the throttle lever and absorbs the additional "breakover" movement of the cable.
