摘要： PURPOSE:To enable to prevent air-fuel mixture from becoming lean at the medium and high speed operational range of an engine, by opening a bleed air intake port at a position near a venturi on the upstream or downstream sides of the same. CONSTITUTION:An intake pipe 11 having an intake port 10 opened in an intake passage 1 is connected to a lead jet 8 at a position near a venturi 2 on the upstream side of the same, and a side portion if the intake passage 1 and the pipe 11 are communicated with each other via a small-diameter jet 12. With such an arrangement, air bubbles are produced in an emulsion pipe 9 at the time of low- speed operation of an engine since the velocity of air flow in the intake passage 1, so that atomization of fuel supplied from a main nozzle 6 is promoted. Further, since the velocity of air flow at the intake port 10 is increased as the engine speed is increased from low, medium to high, air bleeding effect is reduced and the air-fuel mixture becomes rich, so that almost no air bleeding is caused. Therefore, it is enabled to keep the air-fuel ratio at a required value and to prevent increasing of the specific fuel consumption and deterioration of exhaust gas without adversely affecting the driving performance of the engine.

摘要： PURPOSE:To decrease fuel supply by forming an aux. bleed air passage in a carburettor equipped with an emulsion tube and thereby increasing the amount of air bleeding during high speed operation. CONSTITUTION:An emulsion tube 28 is fixed by pushing from below by a main jet 32. An aux. bleed air passage 42 is in communication with a pipe 44 adjacent to another pipe 40 to make convergence aslant with a bleed air passage 36 after passing under it. This aux. bleed air passage 42 makes convergence so as to be oriented in the flowing direction of the bleed air in the bleed air passage 36. When the revolving speed of the engine increases, the liquid level in the emulsion tube 28 and a gap 34 sinks to approach the liquid level B. Accordingly the number of small holes exposed above the liquid level B in the emulsion tube 28 increases also, so that air is supplied to the gap 34 not only through the bleed air passage 36 but also through the aux. bleed air passage 42.

摘要： PURPOSE: To supply a stabilized mixing ratio, by correcting the pressure in a float chamber under supercharged condition into a proper state, while securing a proper differential pressure between the float chamber and a Venturi portion in response to a variation of an air specific weight which follows the supercharging.
CONSTITUTION: In an apparatus for supplying an air chamber 5 with the air pressurized through a comparator 3a of a turbo-supercharger 3 via an air-feeding pipe 4 while supplying a combustion chamber of an engine 1 with a gas mixture generated in a carburettor 6, the air-feeding pipe 4 is provided with a branch tube 4a. One end of this branch tube 4a is connected to sub-air chamber 5a. Both the chamber 5 and 5a are linked to each other through an air tube 8a, and the air tube 8a and the branch tube 4a are respectively provided with throttles 8a and 4b. Moreover the air chamber 5a is communicated to a float chamber 6a through an air tube 8c. Thereby, a pressure high than that within the air chamber 5 is supplied in the float chamber 6a, so that a desired effect may be obtained.

摘要： PURPOSE:To enrich the mixture for acceleration and deceleration at the time of starting and warming up and obtain thereby proper driving by arranging the stem of the carburettor's throttle valve each rically and allowing an auxiliary fuel passage to open at the stem's opposite side to the eccentricity. CONSTITUTION:Besides the main nozzle 3 in the main system and bypass holes 20, 21 in the slow system, an accelerating aux. nozzle 18 open to a venturi 19 and a decelerating aux. nozzle 17 open at the lower flow of a throttle valve 1 are provided. Both nozzles 17, 18 are in communication with a float chamber through solenoid operated valves 15 and 16, respectively, and an auxiliary jet 7. These solenoid operated valve 15, 16 are controlled by a controller unit 22 which is to receive the throttle, crank angle, pressure and temp. sensors 23-26, and the fuel is increased by opening the nozzle for acceleration at the time of warming up and the nozzle 17 at the time of deceleration.
