摘要： PROBLEM TO BE SOLVED: To provide a carburetor foolproof fuel adjustment and limiter assembly. SOLUTION: A valve in the limiter assembly has a rotatable longitudinal shaft, and a head laterally surrounded by a carburetor. A first collar can advance and retreat covering the head. The first collar has a first stop member and a second stop member circumferentially spaced from the first stop member. In the locking position of the first collar, the first collar is engaged with the head and rotated together within a limited rotating range with respect to the carburetor. A pin is held to the carburetor and disposed between the circumferential directions of the first and second stop members. When the first collar is in the locking position and the valve is rotated for minimum fuel flow, the pin is engaged with the first stop member, and when the valve is rotated for maximum fuel flow, the pin is engaged with the second stop member.

摘要： PROBLEM TO BE SOLVED: To provide a circuit for avoiding a backfire, discharge of a blue flame and an exhaust impulsive sound, by reducing unburnt hydrocarbon, by quickly stopping an engine.
SOLUTION: A control circuit is used for a combustion engine, and has an isolating switch and an electronic processor. When receiving an isolating signal from the isolating switch, the electronic processor supplies a first trigger signal in the first ignition timing, and supplies a second trigger signal in the second ignition timing. Its second ignition timing is delayed more than the first ignition timing. When receiving the isolating signal, the electronic processor supplies the first trigger signal corresponding to a spark of the first ratio to engine rotation, and supplies the second trigger signal corresponding to a spark of the second ratio to the engine rotation. The first and second ratios are respectively set to 1 or less.

摘要： PROBLEM TO BE SOLVED: To start an engine securely and eliminate engine stalling on overly rich mixtures of fuel-and-air.
SOLUTION: A pull-starter for the internal combustion engine has a remote-start supporting mechanism operating automatically when pulling a pull-cord 24 of a recoil starter assembly. A releasable coupling 48 of the assembly is temporarily engaged with a recoil pulley of the recoil starter assembly around which the cord is wound. When starting to pull the cord 24, a link constituted and arranged to move a reciprocating piece of the coupling together with the pulley 26 and operate the start supporting mechanism is pulled. When releasing the cord, the reciprocating piece and the recoil starter assembly return to basic positions automatically. Preferably, the releasable coupling has a roller 74, which is engaged with the reciprocating piece rotatably and is arranged on an outer side in the radial direction from the pulley. The cord is wound for several times to surround the pulley and the roller, is wound only around the pulley as remaining winding, and is pulled out of a housing of the recoil starter assembly.

摘要： PROBLEM TO BE SOLVED: To provide an ignition module used in a capacitor discharge ignition (CDI) system capable of charging at wide range of engine speed and reducing number of components and cost. SOLUTION: The capacitor discharge ignition (CDI) system is used in various light load internal combustion engines including devices used on a lawn, in a garden, and other outdoors in general. In an embodiment, the CDI system is provided with an ignition module including a first switching unit short-circuiting a charging coil in an early stage of charging cycle. Since the ignition capacitor is charged by a flyback charging method after short-circuiting the charging coil, the first switching unit is turned off. After that, a second switching unit discharges the ignition capacitor and discharge is used for starting combustion process. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that fuel is continuously evaporated from a fuel container but the evaporation amount is not limited to the volume of the fuel container, and upon moving a device using a carburetor and an engine, fuel is spilled from a fuel float chamber.
SOLUTION: The fuel system for a carburetor that supports operation of an engine includes a body with a bore, a fuel source communicated with the bore and from which fuel is supplied to the bore for delivery to the engine, a drain unit, and a control. The drain unit is communicated with the fuel source to selectively receive fuel from the fuel source and has a fuel chamber and an actuator operable to vary the volume of the fuel chamber. The control is communicated with the actuator to permit fuel flow from the fuel source to the fuel chamber when the engine is shut down and to cause fuel to flow from the fuel chamber to the fuel source prior to starting the engine.

摘要： PROBLEM TO BE SOLVED: To provide a carburetor having an auxiliary fuel/air supplying device, wherein the carburetor can be automatically operated to open and close the conduit of the auxiliary fuel/air supplying device, and does not require the manual operation of a control valve for this purpose.
SOLUTION: The carburetor comprises a fuel/air mixing passage having a throttle valve, a hole having a valve which partially defines a valve drive chamber, and a divided fuel/air mixing chamber which communicates with the fuel/air mixing passage at the position located on the downstream side of the throttle valve. A fuel passage and an air passage communicate with the fuel/air mixing chamber. A purge device communicates with the valve drive chamber, and can be operated to move the valve to the opened position in order to open the fuel/air passage toward the fuel/air mixing chamber. As a result, the fuel/air mixture flows from the fuel/air mixing chamber into the fuel/air mixing passage located on the downstream side of the throttle valve.

摘要： PROBLEM TO BE SOLVED: To provide a by-pass pressure regulator which can generate an uniformly regulated output pressure and a uniformly regulated flow rate.
SOLUTION: The by-pass pressure regulator of liquid fuel has a body, a valve chamber formed by the body, a valve seat, and an inside continuous peripheral surface. The inside continuous peripheral surface partially forms the valve chamber, and is arranged on a downstream side in the axial direction of the valve seat, and the radius of the inside continuous peripheral surface increases with the distance toward the downstream side in the axial direction of the valve seat. The widened valve head of the pressure regulator is at least partially arranged in the valve chamber, and can move in the axial direction within the range from the closed position engaged with the valve seat to the closed position separated from the valve seat. The valve head has an outer peripheral edge. When the valve head is positioned at the closed position, the outer peripheral edge is positioned in the neighborhood of the inside continuous peripheral surface of the valve chamber. The inside continuous peripheral surface is provided with a cylindrical portion and an enlarged portion arranged on the downstream side of the cylindrical portion. The outer peripheral edge of the valve head is arranged in parallel with the cylindrical portion in the axial direction when the valve head is located in the closed position, and is arranged in parallel with the enlarged portion in the axial direction when the valve head is located in the opened position.
