Abstract: A system for mixing fumigation fuel with the intake air in a compression ignition engine includes a variable area venturi in an engine intake air duct to draw controlled amounts of a pre-mixed fumigation fuel/air mixture into the main air stream in proportion to the amount of suction created downstream of the variable area venturi by the engine air flow. The variable area venturi creates a pressure depression proportional to the engine air flow motivating the fumigation fuel/air mixture to flow into the engine along with the main air stream at a rate related to the engine load and speed. The variable area venturi includes a housing having a downstream branch connected to a conventional demand-type mixer which is supplied with the fumigation fuel via a demand-type regulator, and air through a filter from the atmosphere. The variable area venturi is formed by a spring-loaded, normally closed flapper valve which variably opens in response to air drawn through the housing by the engine. The variable area venturi thus created provides a proportional control of the fumigation fuel introduced into the main air stream over a wide range of engine operating conditions with relatively small pressure drops.

Abstract: A member adjacent to an engine, as an engine cover such as an engine head cover and oil pan and an air cleaner, is made of fiber layers by shaping organic or inorganic fibers mixed with a resin and its crosslinking agent while heating so as to cause a crosslinking reaction, thereby absorbing vibrations transmitted from an engine and remarkably decreasing noises resulting from surface vibrations of the member with the aid of the damping capacity of the fiber layers.

Abstract: A variable venturi down-draft carburetor comprises a one-piece unitary casting that defines an induction passage and upwardly open cavities constituting a float chamber and a recess in which a movable venturi member is housed. A throttle valve, main fuel jet, and venturi member are all housed wholly within the confines of the casting, and the casting is covered by a single plate that closes the upwardly open cavities and defines an air inlet orifice to the induction passage. By housing the throttle valve, main jet and venturi in one unit, operation of the carburetor is unaffected by variations in the cover plate produced by manufacturing tolerances. Access to the interior of the carburetor is achieved simply by removal of the plate, which does not, in itself, affect the adjustment of the carburetor. The casting preferably includes integral mountings for a vacuum motor, and/or acceleration pump, and/or an automatic choke.

Abstract: Disclosed herein is a carburetor including a housing having a throat, means for supplying fuel to the throat intermediate its opposite ends, the fuel supplying means including a tube extending into the throat and including a plurality of fuel supply openings spaced along its length. A pivotable throttle member is positioned in the throat intermediate its opposite ends and is pivotable between a fluid flow restricting position and an open position. The pivotable throttle member includes a cam surface. The carburetor is also constructed such that an increased number of the openings supply fuel to the throat as the throttle member pivots from a fluid flow restricting position to an open position and the openings are closed as the throttle member pivots from an open position to a fluid flow restricting position. This is accomplished by a sleeve surrounding the tube and supported for slidable movement on the tube, and a cam follower engaging the cam surface, the cam follower carrying the sleeve whereby the sleeve is slideable on the tube in response to movement of the cam surface with respect to the cam follower.

Abstract: A combination fuel introduction, distribution and air shaping device is provided for a fuel carburetion system of an internal combustion engine. The distributor is elongated and of generally inverted tear-drop cross-section. Fuel discharge openings are spaced longitudinally near or at the bottom of the distributor. The distributor extends across the intake air duct of an air-fuel mixing and modulating device that is adapted to deliver a mixture of finely divided fuel droplets in air to the intake manifold of an internal combustion engine. The body of the distributor divides the intake air flow into two converging air streams which entrain the fuel as liquid droplets sweeping it from a helically coiled wire extending along the downstream side of the distributor and uniformly distributing the droplets in the air streams.
