Abstract

991,964. Spray carburetters. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES. Jan. 31, 1964 [Feb. 8, 1963], No. 4276/64. Heading FIB. In a carburetter having a main throttle valve 2, Fig. 1, and a suction-actuated auxiliary throttle valve 3 which controls a fuel metering needle 16, a starting carburetter is rendered operative at cold starting to supply fuel through a duct 25 to a space connected to the induction pipe between the valves 2, 3. In Fig. 1 the starting fuel duct 25 leads into the normal fuel delivery passage 19 and is controlled by a valve 26 controlled by a bimetallic coil 40 and by a piston 32 responsive to suction downstream of the throttle valve 2. When the engine is cold the coil 40 lifts valve 26 and also sets a fast idle cam 44 to the starting position. After starting, the induction manifold suction, transmitted to chamber 35 through passage 34, pulls down piston 32 to reduce the mixture richness until ports 37 are opened, whereby the suction on piston 32 is moderated and the valve 26 remains held in a partly closed position. When the engine heats up, coil 40 closes the valve 26 to put the starting passage 25 out of action. In a modification passage 25 delivers directly into the space between throttles 2, 3 through a separate outlet and in a further modification passage 5 delivers into a by-pass as in Specification 962,093. In Fig. 3 the main fuel delivery passage 5 and the starting passage 25 deliver into a space 21 connected to the induction passage, the fuel and air mixture being drawn off by a pump 23 and forced through a nozzle 24. In Fig. 10 the starting needle 26 and fast idle control means 57 are controlled by a wax capsule 52 which may be heated by engine cooling water or lubricating oil or by hot air drawn from the vicinity of the exhaust pipe. In Fig. 15 the needle 26 is replaced by a disc valve 71 having a groove 72 which places a starting nozzle 69 into communication with the passage 74 leading to the induction passage.
