摘要： A variable venturi carburetor wherein the suction piston is fully closed with respect to the venturi section at engine stop to elevate the negative pressure at the time of cranking, and is opened to a predetermined degree at the time of idling, thereby obtaining stable driving performance at a suitable air-fuel ratio. The suction piston slides, via a spring, into and out from a suction chamber communicating with a mixing chamber via a negative pressure path and has at its head a metering needle to face a metering jet. The low negative pressure occurring in the mixing chamber along with cranking is reliably applied to the gap between the metering needle and the metering jet which is wider than the gap in their matching state at the time of idling. Hence, the engine starts operating with an over-rich air-fuel ratio. The suction piston is shaped in such manner so as to close a venturi section on the upstream side with respect to the base portion of the metering needle at the time of stop of the engine. A venturi-crossing flange is disposed at a location corresponding to the position in the venturi section of either one or both of the suction piston head and a barrel member of the above-mentioned venturi section. Alternatively, an atmospheric pressure is communicated with the negative pressure to the suction chamber in order to enable driving at a set air-fuel ratio with a suitable lift movement.

A first flat squish area is formed between the flat peripheral top face of the piston and the flat bottom face of the first raised portion. A second spherical shell shaped squish area is formed between the spherical bottom wall of the third raised portion and the spherical rear face of the second raised portion. The axis of the connecting passage is located in the extension of the second squish area.

摘要： Disclosed is an internal combustion engine with an auxiliary combustion chamber having an exhaust gas recirculating device for recirculating the exhaust gas from the exhaust system into the intake system. The auxiliary combustion chamber is connected only to the main combustion chamber via at least two connecting passages. The connecting passages are arranged so that the combustible mixture introduced into the auxiliary combustion chamber from the main combustion chamber via one of said connecting passages strengthens the swirl motion of the mixture created by the combustible mixture introduced into the auxiliary combustion chamber from the main combustion chamber via the other connecting passage.

摘要： A fuel controller has a fuel cut-off device in the form of a solenoid valve connected to an intermediate part of an air bleed commmunicating with the well of a variable choke carburetor. The fuel controller also employs a vacuum changeover valve which communicates with the engine intake manifold through a passage way and is connected to the air bleed between the solenoid valve and an air jet upstream of the solenoid valve. The solenoid valve is opened when the engine is decelerating in order to allow the well and the air bleed to communicate with each other, thereby controlling the air-fuel ratio. When the key switch is IC, the air bleed and the vacuum changeover valve communicate with the well, thereby cutting the supply of fuel to the mixing chamber.
