摘要： An air-fuel ratio control device of an internal combustion engine having a carburetor. An air bleed passage is connected to a fuel outflow passage of the carburetor, and an electromagnetic control valve is arranged in the air bleed passage. The control valve is controlled by the detecting signal of an oxygen concentration detector arranged in the exhaust passage so that the air-fuel ratio of a mixture fed into the cylinder of an engine becomes equal to the stoichiometric air-fuel ratio. After the completion of the warm-up of an engine, the opening area of the control valve is maintained within a fixed range. Before the completion of the warm-up of an engine, the opening degree of the control valve becomes larger than the above-mentioned fixed range.

摘要： Disclosed is an internal combustion engine for an automobile having at least one cylinder associated with a primary intake system and another cylinder or cylinders associated with a secondary intake system. Each of the primary and secondary intake systems comprises a choke valve, a throttle valve and a carburetor. The engine includes a throttle valve controlling device adapted for operation in response to a negative pressure fluctuating according to the degree of opening of the throttle valve in the secondary intake system for maintaining the throttle valve in the secondary intake system in the vicinity of its idling position when the throttle valve in the primary intake system is in the vicinity of its idling position and opening fully the throttle valve in the secondary intake system when the throttle valve in the primary intake system is far away from its idling position. Also included is a fuel supply controlling device adapted to close a main fuel passage in the carburetor of the secondary intake system when the throttle valve in the primary intake system is open to an extent narrower than a predetermined level, while opening the main fuel passage when the throttle valve in the primary intake system opens to its predetermined level or wider. Thus, the engine operates at medium or light loads with smaller pumping and friction losses and a smaller fuel consumption and discharges a smaller amount of harmful exhaust gas. The cylinder associated with the primary intake system may be a cylinder having an ordinary combustion chamber or alternatively, a cylinder adapted for operation with a lean fuel-air mixture and having a main combustion chamber and an auxiliary combustion chamber communicating with each other through a passage in which sparking electrodes are located.
