摘要： PROBLEM TO BE SOLVED: To lower the discharge of the harmful matter in a warm-up operation stage after starting an internal combustion engine. SOLUTION: Since evaporation of the fuel is performed at a relatively low temperature, the formed fuel steam is composed of the only easy evaporative fuel component, and in this case, the fuel steam formed in an evaporation range 30 by a fuel evaporator 19 can be supplied to the air, which is sucked by a combustion chamber 10, so as to form the air-fuel mixture in the downstream of a throttle valve.

摘要： PURPOSE:To make it possible to carry out compensation to the rich side upon full open and low speed running, enrichment upon cranking, etc., by providing, upstream of a slidable throttle type carburetter, a fuel supply valve which is electronically controlled in accordance with the operating parameters of an engine. CONSTITUTION:Upon cranking for starting an engine, such cranking is detected by a control circuit 9 which, therefore, actuates a fuel injection valve 8 for injecting auxiliary fuel that is added to main fuel fed from a main nozzle 4. Accordingly, a mixture is sufficiently enriched for smoothly carrying out the starting of the engine. Thereafter, when the engine is in the condition of complete combustion, the control circuit 9 decreases the open degree of the fuel injection valve 8 so that the overenrichment of the mixture is prevented. When an accelerator is opened during engine operation, a piston valve 3 and a jet needle 5 are raised through an accelerator arm 6 for increasing the supply amount of fuel from the main nozzle, and when the open degree of the accelerator exceeds a predetermined value, the supply amount of fuel is made constant.
摘要翻译：目的：通过在可滑动节气门式化油器的上游设置一个按照电子控制的燃料供给阀，可以在全开和低速运行，丰富的起动等方面对富油进行补偿与发动机的运行参数。构成：在起动发动机起动时，控制电路9检测到这样的起动，因此控制电路9启动用于喷射辅助燃料的燃料喷射阀8，喷射辅助燃料添加到从主喷嘴4供给的主燃料。因此，足够丰富，以顺利地执行发动机的启动。此后，当发动机处于完全燃烧的状态时，控制回路9降低燃料喷射阀8的开度，从而防止混合物的过度富集。当发动机运转时加速器打开时，活塞阀3和喷射针5通过加速器臂6升高，以增加从主喷嘴的燃料供给量，当加速器的开度超过预定值时，使燃料的供给量保持恒定。

摘要： PURPOSE:To enable safe driving of an engine and to reduce flue gas by providing a fuel with excellent ignitionability only from a carburetor while a throttle valve opening degree is small, and by providing a fuel with poor startability from a fuel supply valve when the throttle opening degree reaches a predetermined value. CONSTITUTION:In an air intake pipe 4 of a spark ignition engine 1, an air filter 8, a carburetor 9, a throttle valve 10 and a fuel supply valve 11 are arranged in order from the upper stream side. the carburetor 9 is constituted of a float chamber 12, a float 13, a fuel supply pipe 14, a nozzle pipe 15 and an air bypass pipe 16 for generating differential pressure, and the tip end of the nozzle pipe 15 is opened in a venturi part 17 of the intake pipe 4. At start of the engine, a fuel with excellent iginitionability such as gasoline is supplied from the carburetor while an opening degree of the throttle valve 10 is small. In the meantime, when the throttle opening degree reaches a predetermined value, a fuel with poor startability such as light oil, lamp oil or alcohol is supplied form the fuel supply valve 11.

摘要： PURPOSE: To promote fuel to be atomized into a fine particle and improve low temperature startability of an engine when it is in a low temperature, by providing a passage, which introduces bleed air, in a starting fuel passage of a starting fuel device supplying starting fuel to the downstream of a throttle valve.
CONSTITUTION: A device, connecting an air bleed passage 20 with a starting fuel passage 9 on its half way and opening an inlet of the passage 20 to the internal wall of a throttle body 4 in the upstream of a throttle valve 6, enables bleed air to be introduced to the starting fuel passage 9. Now the device, if an engine 1 is started by placing a solenoid operated valve 11, 12 opening and closing the starting fuel passage 9 and a bypass air passage 10 respectively in an open condition, allows starting fuel and bypass air to flow in the both passages 9, 10 being mixed in their confluent point and jetted to the downstream of the throttle valve 6 in an intake passage. Here the device mixing the starting fuel with the bleed air introduced from the air bleed passage 20 and forming the fuel in an emulsion state joining with the bypass air, enables atomization to be promoted.
