Abstract: A fuel shut off solenoid device of a carburetor has a solenoid chamber which typically fills with fuel. When the solenoid device is energized, fuel flows from a fuel chamber into a mixing passage of the carburetor to mix with air. During the energized state, heat from the solenoid tends to vaporize the fuel within the solenoid chamber. Also when energized, the solenoid device is held in a retracted position whereby a head at a distal end of the shaft mates with or seals to a washer which in turn seals to an upward face of the encasement of the fuel shut off solenoid device. Thus the potential migration of large vapor bubbles from the solenoid chamber to the mixing passage of the carburetor is eliminated, providing a smoother idling or running engine at light loads.

Abstract: A piston (20) for an internal combustion engine includes an upper crown (22) and a lower crown (24) that are each fabricated using a same strong material, such as steel and fastened together using a plurality of fasteners (50). The piston (20) provides increased strength resulting in improved design flexibility and smaller sized engines that produce the same amount of power. Piston ring grooves (100, 102, 104) are also provided in either one or both of the upper and lower crowns (22, 24) which control piston combustion height. A deeper combustion bowl (72) is also available with the piston (20).

Abstract: A fuel needle valve assembly of a carburetor has a retainer which yieldingly restrains the rotational fuel flow setting capability of the needle valve. The retainer engages a shank of the needle valve and a parallel shaft, both of which project from the carburetor body. The retainer exerts a force which laterally displaces the projecting shank with respect to the shaft. The retainer has sufficient strength to ensure the factory set rotational setting of the fuel needle valve does not alter when a limiter cap is press fitted to a distal head of the needle. Furthermore, wherein the shaft is also a shank of a second needle valve, the same retainer laterally displaces the projecting shanks of both needle valves.

Abstract: A lighting system for preferentially illuminating the seating area of a mass-transit vehicle includes a light fixture with a lamp housing longitudinally disposed above the seating area An electrically energized light source is mounted at least one end of the light fixture. At least one solid-core semi-rigid light pipe extends from and is optically coupled to the light source. The light pipe receives light from the light source, transmits the light along its length, and emits the light laterally into the passenger compartment. The light pipe runs parallel to and is suspended from the lamp housing between the lamp housing and the seating area so that the lamp housing can direct laterally emitted light from the pipe into the seating area.

Abstract: A carburetor fuel mixture adjustment assembly including a threaded cylindrical needle valve receptacle formed in a carburetor main body and intersecting a fuel passage. A needle valve body is threaded into the needle valve receptacle and includes a needle that extends into an axially-aligned needle seat orifice portion of the fuel passage. The needle is axially movable within the needle seat orifice by rotation of the needle valve body to control how much of the orifice is open to fuel flow. A valve spring disposed between a head of the needle valve body and the carburetor main body biases the head away from the carburetor main body. A needle stabilizer engages and cooperates with the valve spring in laterally biasing the needle into one position relative to the needle seat orifice. The lateral bias assures constant fuel flow through the orifice by resisting needle movement.

Abstract: An engine fuel apparatus has a fuel and air mixing passage through which a rich fuel and air mixture is provided to an engine to support the operation of the engine at idle and low speed, low load engine operation, and a pressurized fuel delivery passage provides liquid fuel to a downstream fuel injector for operation of the engine at high load, high speed and wide open throttle engine operating conditions. A shut-off valve prevents the flow of fuel to the mixing passage when a throttle valve therein, which controls engine operation, is opened a predetermined amount from idle to prevent the flow of the fuel into the mixing passage at high load and/or high speed engine operation. Another shut-off valve prevents the flow of pressurized fuel to the downstream fuel injector device when the throttle valve is between idle and a predetermined position off of idle to prevent the flow of pressurized fuel to the fuel injector device under low speed, low load engine operation.
