    Abstract: PROBLEM TO BE SOLVED: To excellently maintain engine operation performance, by reducing a bubble quantity sent to the main jet downstream side, in a carburetor of an engine having a fuel passage communicating with a fuel reservoir on the main jet opening part side from the constant fuel chamber side on the float chamber bottom part side. SOLUTION: This carburetor opens-closes the fuel passage 7a by closely contacting or separating a valve element part of a plunger 11 by driving of a fuel cut solenoid 10A with or from an inlet side seat part of the fuel passage 7a communicating with the fuel reservoir 7b on the opening part side of a main jet 5. The plunger 11 is formed as a two-stage structure of extending a center bar 11a composed of a columnar member so as to coincide with the extending direction of the fuel passage 7a from a tip surface continuing with the valve element part. When the fuel passage 7a is opened, a part for inserting the center bar 11a is reduced in a maximum flow passage width while forming a predetermined clearance between an inner peripheral surface of the fuel passage 7a and an outer peripheral surface of the center bar 11a, to restrict the inflow of bubbles into the fuel reservoir 7b.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for controlling an engine capable of easily realizing idling stop operation. SOLUTION: A mode selector switch 37 selects a low idle mode to drop the rotational speed of an engine 31 in a low idle state or an idling stop mode for bringing into an idling stop mode. The operation of a single operation low idle switch 27 gives a low idle state instruction in the low idle mode and an idling stop state instruction in the idling stop mode. A controller 32 controls the engine 31 in the low idle state by operating the single operation low idle switch 27 in the low idle mode, controls the engine 31 in the idling stop state by operating the low idle switch 27 in the idling stop mode, and re-starts the engine by re-operating the single operation low idle switch 27.

    Abstract: PURPOSE:To improve responsibility in detecting acceleration and deceleration by constituting the negative pressure switch of a fuel cut system to be differential pressure type, and so controlling the system as to apply minimum negative pressure to one chamber of the switch when a throttle valve is open, and slightly deeper negative pressure than the aforesaid minimum negative pressure at the time of deceleration. CONSTITUTION:A fuel cut device 10 fitted to a slow fuel system comprising a slow fuel passage 8 having a solenoid valve 32, outputs a fuel cut signal from a fuel cut control circuit 31 to a solenoid valve 32 when an engine decelerates with a negative pressure switch 13 turned on, and when an engine speed is equal to or more than the predetermined value. In this case, the first negative pressure port 11 for reducing negative pressure according to an increase in the opening of a throttle valve and the second negative pressure port 12 for contrarily increasing the negative pressure are provided, and the second negative pressure port 12 is made continuous to the chamber 13b of the negative pressure switch 13. Also, the chamber 13c of the negative pressure switch 13 is applied with the shallow minimum negative pressure of the first negative pressure port 11 when a throttle valve is open, and with negative pressure slightly deeper than the minimum negative pressure during deceleration, via a working negative pressure control device 20.
