| PURPOSE:To improve fuel response characteristics by making an air diluting leak orifice opened in the direction of introducing dynamic pressure upstream of a throttle valve, in a fuel discharge portion between a sonic orifice and the leak orifice. CONSTITUTION:A mixture from a main jet 8 and a main air bleeder 9, and a mixture passing through an injector 15 and a sonic orifice 11 serve as supply source in the intermediate speed range, while a mixture is supplied from a small venturi 3 and the injector 15 in the ratio of 2:1 in the heavy load range. Further, a leak orifice upstream of a throttle valve increases the flowing velocity of a fuel discharge portion 14 the more as the lower vacuum pressure is, since the leak orifice has an opening 12a directed to the upstream side of an intake air pipe 1, thereby the distributing characteristics and as well the response of fuel atomization are improved. Further, the selection of pressure level upon heavy load state or low negative pressure state may be made by suitably selecting both orifices 11, 12. | ||||||

| PURPOSE: To feed an adequate amount of fuel to an automobile engine in its wide range operational state through the above described device, by connecting the return flow line of a fuel pressure regulator to the richer nozzle passage of a throttle main unit and opening a valve at high loaded operation of the engine at its high speed. CONSTITUTION: A fuel pressure regulator 12 is provided with a seat part on the upper side of a diaphragm supported by a coil spring, when prescribed pressure fuel passes, the seat part is sealed by a seat, however when high pressure fuel is fed from a pipe 11, the diaphragm is depressed to open the seat part, and a surplus amount of the fuel is released to a pipe 10. While in a throttle main unit 1, negative pressure is generated in a richer nozzle 8 as intake air quantity increases, and a check ball 5 is lifted by overcoming tension of a spring 6, then fuel from a pipe 4 is sucked and supplied from the pipe 10 of the fuel pressure regulator 12 through a fuel passage 14.

| PURPOSE: To atomize the fuel into fine particles and improve the distribution of fuel mixture among the cylinders at the feeding of fuel mixture being injected at a portion downstream of the throttle valve, by disposing an orifice for fuel injection in face of an orifice for injecting bleed air. CONSTITUTION: When such an amount of fuel as required by the internal combustion engine is ejected from injection valve 200, it is mixed with bleed air supplied from air bleed passage 104 and ejected from orifice 102 after it is atomized into fine particles in passing through sonic nozzle 203. Then, atomized fuel collides with bleed air supplied through air bleed passage 104' and accelerated at sonic nozzle 105, so that its horizontal velocity component becomes substantially zero. At the same time, atomized fuel is scattered in every direction in venturi 103 and drawn into the combustion chamber while being mixed with air fed through throttle valve 101. Thus, atomized fuel from sonic nozzle 203 is scattered in every direction by the bleed air from sonic nozzle 105 with its velocity being lowered by the bleed air, so that mixture can be distributed uniformly to a plurality of cylinders.

| PROBLEM TO BE SOLVED: To obtain satisfactory and stable operation by dealing with even sudden load variable without time delay, by automatically adjusting an opening degree of a solenoid valve before performing actual work after engine start and by providing a proper air-fuel ratio.SOLUTION: After an engine 7 is started, when being within a fuel flow rate adjustment rotating speed range applying a fixed load in a work rotating speed range of the engine 7 where a throttle valve 4 is opened for a fixed opening degree, a detected rotating speed is fed back with respect to a target rotating speed, a fuel flow rate is adjusted by controlling an opening degree of a solenoid valve 3 of a vaporizer 1 to control the detected rotating speed, and the valve opening degree is determined to achieve the target rotating speed. By operating at the determined valve opening degree, a combustion state of a fuel in the engine 7 is brought into best state. | ||||||

| PROBLEM TO BE SOLVED: To improve the sharpness of an injection finish of fuel when a needle closes an injection hole. SOLUTION: Flow passage area A1 of a fuel supply orifice 61 is set to be smaller than a flow passage area A2 of an injection control chamber orifice 33. Thus, in the valve closing process in which the needle 51 closes the injection hole 23, fuel pressure is supplied from a common accumulator 2 to a fuel sump 52 and an injection control chamber 3 so that pressure for supplying fuel to the fuel sump 52 is lower than that to the injection control chamber 3. In the valve closing process, therefore, force to an injection hole 23 side acting on the needle 51 can be increased, and valve closing speed of the needle 51 can be increased.

| PURPOSE: To load this device suitably for a small boat being safe and easy in manufacture and assembly by a method wherein a fuel pump, a fuel supply passage to supply high pressure fuel to a fuel injector, and a low pressure fuel metering chamber are disposed at a common body. CONSTITUTION: A supply air passage having a supply air valve opened by a cam drive mechanism is formed at the cylinder head of an outboard prime mover. Fuel from a tank is supplied to a fuel pump 26 through a metering mechanism 22 and a fuel filter 24, and after boosting, the fuel is supplied through a fuel feed passage 30 to a fuel injector in an intake passage. A fuel pressure supplied to the injector is controlled by a fuel pressure regulator 76 and excessive fuel is returned to the metering mechanism 22. Meanwhile, combustion air is supplied to the supply air passage through a throttle body 34, a supply air chamber 36, and a ram tube 38. The metering mechanism 22 is provided with a vaporized air separator 42 containing a vaporized fuel dome 88, and separated vaporized air is injected to an air passage 82 situated downstream from a throttle valve 84 through a delivery port 92.
