摘要： The present invention provides a diaphragm carburetor wherein heat transferred from the engine to the carburetor through the insulator is reduced to lower the temperature of the carburetor unit and reduce the occurrence of bubbles in the fuel. The carburetor of the present invention is a diaphragm carburetor in which a fuel channel that extends from a pump chamber of the carburetor to a constant-pressure fuel chamber is divided into two branches to form one branch as a main fuel channel connected to the constant-pressure fuel chamber, and the other branch as a fuel circulation channel for passing the fuel through the body side surface of the carburetor on the insulator side, or the body side surface of the insulator on the carburetor side, causing the fuel to make a circuit around the carburetor, and returning the fuel to the fuel tank.

摘要： A method and apparatus for operating an electric ignition, internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer that transfers heat from the engine coolant system to the fuel mixture as it leaves a fuel introducing device such as a carburetor; a fuel mixture heater for heating the mixture above the vaporization temperature of the liquid fuel; and, a mixture homogenizer for thoroughly stirring the fuel mixture that is located in the fuel mixture flow path intermediate the vaporizer and heater. The homogenizer is operative to compress the fuel mixture under certain engine operating conditions and the heater forms the intake manifold for the engine and includes branch flow paths and associated conduits that communicate directly with each combustion chamber through a valve controlled port. The fuel mixture flow path from the homogenizer is constructed to minimize energy losses to the ambient.

摘要： A method and apparatus for operating an internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer, a fuel mixture heater and a mixture homogenizer located in a fuel mixture flow path intermediate the vaporizer and the heater. The fuel vaporizer includes structure defining an inner heat exchange chamber which receives air and entrained fuel discharged by a fuel introducing device such as a carburetor. The fuel mixture is heated and at least partially vaporized by engine waste heat derived from the engine cooling system or alternately the engine exhaust system. To facilitate the transfer of heat to the fuel mixture, a pair of heat exchange members are disposed in the chamber and include a supply tube defining a flow path for fluid carrying engine waste heat and a plurality of bristle-like heat exchange surfaces radiating outwardly from the supply tube. The bristle-like surfaces are located in heat exchange relation with the fuel mixture in the vaporizing chamber and transfer heat from the heat exchange fluid to the fuel mixture as the fuel mixture passes through the vaporizer.

摘要： A system is disclosed for preventing overheating of a carburetor of the type which is placed with an intake manifold above an exhaust manifold. A heat insulating plate is disposed substantially horizontally between the intake manifold and the carburetor. This plate extends to substantially cover the area above the exhaust manifold. A substantially vertical plate extends upwardly from the heat insulating plate at an edge thereof most distant from the engine. A path is thereby created for the convection currents from the exhaust manifold to bypass the carburetor.

摘要： Screw holes are provided on a contacting surface of an insulator so as to enable a carburetor to be mounted on the insulator at a plurality of positions rotated about an axial center of an intake hole. The insulator is mounted on a cylinder at a predetermined position while the carburetor is mounted on the insulator by inserting bolts for mounting the carburetor into the screw holes through through holes of the carburetor. Accordingly, the carburetor can be mounted at a plurality of positions rotated about the axial center of intake holes relative to an engine body. Thus, a protruding direction of a throttle lever from the carburetor, i.e., an operating direction of the throttle lever, can be changed.

摘要： In a starter for an internal combustion engine, comprising: a pinion; shift means for moving the pinion into mesh with a ring gear of the engine; a housing for accommodating the pinion and the shift means; an electric motor for rotating the pinion; a substantially cylindrical motor casing for accommodating the electric motor; a contact unit for selectively providing electric power to the electric motor; a brush holder stay disposed between the housing and the motor casing, the brush holder stay having a cavity opened toward the motor casing and the contact unit being mounted in the cavity; and a cover for covering the cavity of the brush holder stay, the cover is made of a flexible member so that the cover is naturally curved, and the cover is disposed between the brush holder stay and the motor casing with its concave surface facing the brush holder stay so that the cover is pushed toward the brush holder stay by an axial end of the motor casing. Thus, when pressed against the brush holder stay by the motor casing, the cover is deformed and made straight to produce a resilient restoring force, whereby increasing the pressing force to ensure sufficient watertight sealing effect.
