摘要： PROBLEM TO BE SOLVED: To provide an engine starting device including a manually-operated primary pump, delivering an appropriate quantity of starting fuel through a simple operation and obtaining satisfactory engine starting performance.SOLUTION: The starting device includes: the manually-operated primary pump 8 arranged on a fuel introduction path 10a connected to the middle of a fuel-feeding path for sucking and pressure-feeding fuel; and a fixed-quantity fuel chamber 5A for temporarily storing the fuel delivered from the primary pump 8, and supplies a fixed quantity of starting fuel from the fixed-quantity fuel chamber 5A to an intake passage during engine starting. The fixed-quantity fuel chamber 5A has a part of the internal wall displaced elastically to allow the internal capacity to expand and contract within a predetermined range, and is connected to a fuel delivery path 11a that has a manually-operated on-off valve 4a and communicates with the intake passage side. The on-off valve 4a is manually opened in a state that the fixed-quantity fuel chamber 5A expands the internal capacity through the operation of the primary pump 8 and is filled with a predetermined quantity of starting fuel, and thereby the fixed-quantity fuel chamber 5A contracts by elastic contractile force and discharges the fixed quantity of starting fuel.

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 carburetor whose low speed system is independent from a main system, wherein connection of fuel is smooth, dispersion in fuel flow rate is low, and high output is materialized.
SOLUTION: A flow rate control mechanism 21 is provided to a low speed system 12 independent from a main system 8. In the mechanism 21, a valve element 24 is linearly reciprocated with a cam 32 provided to a throttle valve shaft 6. The effective area of a low speed fuel passage 16 is increased to main fuel injection timing in accordance with increase in opening from an idle position of the throttle valve. After that, the area is decreased to be made zero at high output area. By so doing, the fuel flow rate in a high pressure area is stabilized and high output is materialized while the connection from low speed fuel to main fuel is made smooth.
