摘要： PROBLEM TO BE SOLVED: To actualize a fuel system for starting and purging, which removes old liquid fuel, residing fuel vapor and air from a diaphragm carburetor of an engine while starting the carburetor and/or the engine with the liquid fuel.
SOLUTION: A starting pump for the fuel system supplies at least the liquid fuel to a starting circuit, preferably supplies at least the liquid fuel and air to a purge circuit for the fuel system. The starting circuit supplies starting fuel to the engine through a conduit connected to an isolated chamber 50 located between an intake nozzle and an exhaust nozzle. The sectional flow range of each nozzle is large enough for the amount of liquid fuel required for starting the engine without flooding it with fuel to flow to the engine. The expanded isolated chamber 50 and the nozzles are combined to prevent the drip of the fuel in a way from the starting circuit to the engine during the normal operation of the engine.

摘要： PROBLEM TO BE SOLVED: To provide a low-cost, rugged, durable, and reliable engine that starts positively at idling. SOLUTION: This pull-cord start system has a recoil pulley coupled to a crankshaft of the combustion engine and a pull-cord wound about the recoil pulley that is pulled to rotate the recoil pulley and thereby start the engine. A throttle override device of the pull-cord start system has a shuttle coupled to the pull-cord that moves from a biased rest position to an active position when the pull-cord is being pulled by a user. The throttle override device and a link mechanism of a Bowden cable extending between a throttle control and a throttle valve of a carburetor is interlinked to the shuttle so that actuation of the throttle control when the shuttle is in the active position will not open the throttle valve that is biased to its idle position.

摘要： PROBLEM TO BE SOLVED: To provide a control system for a low cost, light duty combustion engine. SOLUTION: An engine speed input signal and independent operating sequences are utilized to determine a desired ignition timing. There are several independent operating sequences, each one of which is designed to optimally control the engine under certain conditions. These operating sequences include a Cranking sequence, a Warm Up sequence, a Normal Mode sequence, an Acceleration sequence, a Come Down sequence, a Recovery Bump sequence, and a Part Throttle sequence. During idling conditions, the Normal Mode sequence uses rapid changes in the ignition timing to maintain the engine speed in a small, idle engine speed range. By utilizing these operational sequences, the control system improves the performance of a low cost, light duty engine across a wide array of conditions. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel air mixing device capable of providing desired choke size at an engine start at any throttle valve position by allowing choke valve operation with a simple procedure at the engine start.
SOLUTION: The fuel air mixing device includes a body having a fuel and air mixing passage, a throttle valve and choke valve moveable between first and second positions to control at least in part the fluid flow in the fuel and air mixing passage, and throttle and choke control members associated with the throttle and choke valves, respectively. The choke control member is associated with an engine starting system so that the choke valve is moved to its second position upon actuation of the starting system. The choke control member is selectively associated with the throttle control member to hold the choke control member in a position spaced from its first position. In this manner, the throttle valve and choke valve is automatically positioned in a desired position for starting of the engine upon actuation of the engine starting system.

摘要： PROBLEM TO BE SOLVED: To provide a device preventing unprepared motion of a fuel flow calibration setting needle.
SOLUTION: A body of a rotary throttle valve type carburetor includes a throttle chamber communicating to a air fuel mixing passage and an air fuel mixing passage, and a fuel flow passage. A throttle valve is stored in the chamber movably in a rotation and an axial direction, and moves between an idling position and an expansion open position to control air fuel mixture flow in the mixing passage. An insertion valve threadedly inserted in and retained by the carburetor adjusts flow rate of fuel from the carburetor through the fuel flow passage. The insertion valve is rotated and moved in an axial direction along the thread by a tool engagement part of the insertion valve. The tool engagement part is not in a round shape and mates with just a special tool. The insertion valve is retained by the throttle valve and moves together with the same. The tool engagement part has a flat surface and is in a roughly D-shape. A carburetor body includes a recess in which the tool engagement part is arranged to limit entrance to the tool engagement part.

摘要： PROBLEM TO BE SOLVED: To provide a vapor separator for improving the cooling efficiency by introducing a baffle. SOLUTION: A fuel pump assembly for use with a fuel injected combustion engine has a liquid cooled vapor separator, and fuel conditioned by the separator is drawn by a high pressure fuel pump. The vapor separator has an internal heat conductive sleeve which defines a fuel chamber or reservoir. A refrigerant chamber surrounds the heat conducting sleeve and is carried laterally between an exterior housing of the fuel pump assembly and the internal sleeve. A baffle is preferably coiled and disposed within the refrigerant chamber to form a refrigerant channel which spirals about the sleeve. The channel has a first end which communicates with a refrigerant passage inlet and an opposing second end which communicates with a refrigerant passage outlet carried by the housing. The introduction of the baffle, therefore, the channeling of refrigerant flow through the spiraling channel, improves the fuel cooling efficiency of the vapor separator. COPYRIGHT: (C)2004,JPO
