Abstract: In an internal combustion engine air cleaner, a thermal sensor delivers a vacuum signal to a vacuum motor which actuates a valve unit controlling admission of ambient temperature and heated air. The sensor receives induction passage vacuum and has a bimetal strip which positions an acetal resin valve ball in an air bleed to create a vacuum signal which varies inversely with changes in the induction air temperature, the bimetal strip and valve ball being enclosed within a protective metal housing which permits prompt response to changes in induction air temperature. This construction permits the induction air flow to be maintained at a predetermined temperature.

Abstract: An improved boom includes a slider assembly for use in supporting telescoping sections of the boom for movement relative to each other. An articulated slider assembly embodying the invention includes a rocker member which is pivotally mounted on one section of the boom. A pair of slider block assemblies are pivotally mounted on the rocker member and slidably engage a supported section of the boom at spaced apart locations. Deflection of the supported boom section is compensated for by pivotal movement of the slider block assemblies relative to each other. A spring type slider assembly forms another embodiment of the invention and has a flexural rigidity such that the deflection of the spring type slider assembly matches the deflection of a supported section of the boom under the influence of an operating load to provide for the transmittal of a uniform bearing load between the supported boom section and slider assembly.

Abstract: A fuel injection system for externally ignited internal combustion engines preferably has one fuel injection location in the air induction tube (manifold). The metering of fuel occurs independently of the condition of the air prevailing at the injection location, the injection location is disposed ahead of the junction of the air induction tube which leads to the individual engine cylinders. Air is brought to a high velocity by means within the induction tube and impinges, at this high velocity, immediately on the injected fuel, enveloping the same. As a result, the mixture preparation is effected without wetting of the inner wall of the induction tube and the means which bring the air to the required high velocity.

Abstract: A fuel induction system for a spark-ignited multicylinder internal combustion engine including a carburetor, a mixing chamber and an intake manifold. The carburetor includes a primary barrel which connects initially to an inlet in the mixing chamber. An outlet from the mixing chamber connects to the intake manifold. The inlet and outlet are arranged such that the direction of air/fuel mixture flow is reversed in passing through said inlet and outlet thereby providing an improved air/fuel mixture, resulting in lower exhaust hydrocarbon and carbon monoxide emission.

Abstract: A method and apparatus for heating the air-fuel mixture in the intake system or intake manifold of an internal-combustion engine which includes a heat exchanger heated by the exhaust gases out of the engine located between the carburetor of an internal-combustion engine and the engine cylinders. The air-fuel mixture is heated by passing through the heat exchanger and around the heat exchanger ports. The temperature of the heat exchanger can be varied to insure maximum vaporization of the fuel in the air stream.

Abstract: An induction system for a gasoline-fueled four-cycle engine having a carburetor which delivers an air/fuel mixture through a primary venturi to a "hot box" evaporation container located in the engine exhaust stream causing any liquid gasoline to be vaporized. The vaporized air/fuel mixture is then conducted to the intake manifold. In V-type engines the "hot box" is located in the exhaust cross-over. At high load a secondary venturi delivers air/fuel mixture directly to the intake manifold. Fuel distribution in multicylinder engines is thereby improved permitting leaner operation without misfire, resulting in decreased hydrocarbon and carbon monoxide emission.

Abstract: A fuel control apparatus for controlling the flow amount of fuel delivered from a carburetor having a power circuit is disclosed, in which the fuel passage of the power circuit permits the fuel in a float chamber of the carburetor from flowing toward the fuel nozzles of the carburetor in response to the reduction in the vacuum led into a vacuum chamber of the carburetor from a vacuum reservation tank in which the vacuum introduced from an intake manifold of a gasoline engine is reserved. The vacuum reservation tank has a considerable volumetric space therein defined by a sealed housing, and is disposed to the exterior of the carburetor. The fuel control apparatus also comprises a means for causing reduction in the vacuum developing in a vacuum region between the vacuum reservation tank and the vacuum chamber of the carburetor.

Abstract: An internal combustion with an arrangement for heating the suction gases in order to promote the vaporization of the fuel contained within the suction gases is disclosed. In the arrangement, the exhaust gases exhausted from the engine are routed around fins formed on the exterior wall of the bottom floor of the intake manifold for receiving the heat of the exhaust gases, and a covering is provided for enclosing the fins of the intake manifold in a closed chamber which is defined between the covering and the exterior wall of the intake manifold. The covering is provided with inlet and outlet ports so as to introduce the exhaust gases into the chamber and so as to drain the exhaust gases from the chamber. The introduced exhaust gases heat the entire surface of each fin so that the heat of the exhaust gases is transmitted to the fuel within the suction gases thereby accelerating vaporization of the fuel.
