Abstract
PURPOSE:To enhance the follow-up controllability at the time of transient state by constituting so that an intake negative pressure having been regulated by the pressure on the upstream side of a throttle valve is introduced into the pressure chamber of a LPG pressure regulator, and further to enable fuel-cut to be carried out by introducing a large negative pressure at the time of a prescribed deceleration. CONSTITUTION:In a regulator 20, a pressure chamber 24 and a fuel control pressure chamber 26 are partitioned by a diaphragm 22, and it is so arranged that a prescribed pressure is applied on the diaphragm 22 by a coil spring 28 (not shown) having been provided in the pressure chamber 24. And this pressure chamber 24 is communicated with both an orifice 32 which opens to the downstream side of a carburetor throttle valve 16 and an orifice 36 which opens to the upstream side of the throttle valve 16 and is provided with a duty solenoid valve 34. Further, the fuel control pressure chamber 26 is communicated with a fuel tank 10 through a fuel inlet 38 on which a valve device 40 is provided, and the fuel after pressure regulation is supplied to an intake pipe 14 through a conduit tube 50 via a fuel measuring part 52. The above solenoid valve 34 is controlled so as to be closed at the time of a prescribed deceleration.
