摘要： A double carburetor including a primary suction conduit (1) and a secondary suction conduit (2) located in a suction passage of an internal combustion engine equipped with a turbosupercharger for supplying supercharged air to a combustion chamber by means of a compressor driven by a turbine rotated by the energy of exhausts has an air-fuel ratio correcting control valve (21) for a primary main fuel system of the primary suction conduit (1) and another air-fuel ratio correcting control valve (22) for a secondary main fuel system of the secondary suction conduit (2). The carburetor also has a drive unit (17) which is operative, when the turbosupercharger is put into action, to actuate the air-fuel ratio correcting control valves (21, 22) for the primary and secondary main fuel systems to correct the air-fuel ratio of fuel-air mixtures supplied to the engine by increasing fuel flow or decreasing air flow therethrough.

摘要： PURPOSE: To obtain the proper air-fuel ratio in the whole operation range by allowing the main air bleed of a pressurization type carburetor to communicate to the inlet side of a turbocharger and controlling the amount of bleeded air according to the difference of the supercharge pressure in the upstream and downstream sides of the carburetor.
CONSTITUTION: When the air pressurized is supplied into a carburetor 3 by a turbocharger, the pressure in the upstream side of the carburetor 3 acts into the diaphragm chamber 16b of an actuator 16, and the pressure in the downstream side of the carburetor 3 acts into the diaphragm chamber 16c through a passage 18 and a check valve 17. When the pressure in the diaphragm chamber 16b becomes larger by a prescribed value or more in comparison with the pressure in the diaphragm chamber 16c, the needle valve 15 of the actuator 16 is opened to allow an adjusting passage 13 to communicate to an air cleaner on the inport side of the turbocharger. Therefore, the internal pressure of a chamber 11 lowers, and the amount of the bleeded air reduced, and air-fuel ratio can be obtained in the whole operation range.

摘要： PURPOSE: To correct the air-fuel ratio by making a carburetor function as a pressurized carburetor by opening and closing a passage connecting a chamber to a float chamber of the carburetor selectively by means of a changeover valve when an engine is operated in supercharged state and to prevent percolation by lowering the temperature of fuel when the engine is operated in non-supercharged state.
CONSTITUTION: When an engine 1 is operated under low load in non-supercharged state, the opening of a throttle valve 20 is small and a high negative pressure in the an intake passage is taken out from a port 21 and acted in a pressure chamber 14 of a changeover valve 10. Resultantly, a passage 9 is closed by the changeover valve 10 and a passage 11 is communicated with an atmospheric port 17. In this state, open air is drawn into an intake passage 19 of a carburetor 6 by the function of suction vacuum developed in the intake passage 19, so that the upper space in a float chamber 12 becomes unsaturated and vaporization of fuel is promoted. At the same time, the temperature of fuel is lowered, so that percolation of fuel is prevented. ON the other hand, when the engine is operated in supercharged state, supercharging pressure is introduced from a chamber 8 into the float chamber 12 via the passages 9, 11 and the changeover valve 10, so that the air-fuel ratio is corrected to a proper value.

摘要翻译：目的：为了通过使化油器作为加压化油器起作用，通过打开和关闭通过当发动机以超荷电状态运行时通过切换阀选择性地连接腔室到化油器的浮子室的通道来校正空燃比，以防止当发动机在非增压状态下运转时降低燃料的温度来渗透。构成：当发动机1在非增压状态下在低负载下运行时，节气门20的开度较小，并且进气通道中的高负压从端口21被取出并作用在压力室14中结果，通道9被切换阀10关闭，通道11与大气口17连通。在这种状态下，空气通过功能被吸入化油器6的进气通道19中在进气通道19中产生吸入真空，使得浮子室12中的上部空间变得不饱和并促进燃料的蒸发。同时，燃料的温度降低，从而防止燃料的渗透。另一方面，当发动机在增压状态下运转时，增压压力经由通路9,11和切换阀10从腔室8引入浮球室12，使得空燃比被校正为适当的价值。

An actuator comprises a diaphragm operatively connected to the valve and first and second chambers defined by the diaphragm. An opening is provided for communicating the first chamber with the intake passage at the upstream side of a throttle valve of the engine, and a passage is provided for communicating the second chamber with the intake passage at the downstream side of the throttle valve. The actuator is so arranged that the valve closes when the difference between the pressures in the first and second chambers exceeds a predetermined value, thereby supplying a rich air-fuel mixture.

摘要： A carburettor for air and liquid fuel under pressure for internal combustion engines has an air/fuel mixing chamber for mixing a controlled flow of air with gasoline and optionally methanol also. The fuel is disintegrated in the mixing chamber into fine droplets by impinging on a solid surface and/or on a stream of air. The mixture is passed into a vaporizer connected to the intake manifold of the engine. A rotary sleeve valve allows or prevents additional air to be added to the mixture in the vaporizer to optimize the air/fuel ratio.
