Abstract
PURPOSE: To improve the starting characteristic of an internal-combustion engine at low temperatures by supplying the starting fuel having an excellent ignitability and mixed with the main fuel by an operation of a valve sensitive to a temperature and negative pressure.
CONSTITUTION: A float chamber 23 and an intake passage 17 are communicated with each other through a main port 22 and a slow port 28, and the fuel feed from each port is provided according to the opening of a sliding throttle valve 19. A fuel passage 29 communicated with the slow port 28 is communicated with a starting fuel passage 30 communicated with a float chamber 31 for starting. The starting fuel passage 30 is also communicated with a crank chamber (not shown in the figure) through a suction pipe 7, and provided with a suction pressure valve 8 to which a pulsation pressure is applied. The suction pipe 7 is provided with a thermal valve (not shown in the figure) comprising bimetal or the like, which is opened at below a predetermined temperature in order to transmit a suction pressure to the valve 8, and by opening the valve 8 the starting fuel is supplied.
