摘要： There is disclosed a thermal-type air flow measuring instrument which judges whether the direction of flow of a fluid, ranging from a static flow to a pulsating flow involving a reverse flow, is forward or reverse, and outputs a signal corresponding to the flow rate of the fluid, thereby measuring the flow rate with high precision. An auxiliary passage is provided in a fluid passage, and is constituted by first, second and third passageways. Two temperature sensing resistors are mounted respectively at an upstream side and a downstream side within the first passageway in close proximity to each other. Most of the fluid, flowed into the first passageway in a forward direction, flows through the second passageway. The third passageway serves to direct a reverse flow of the fluid toward the temperature sensing resistors. Results of measurement of the flow rate of intake air in an internal combustion engine indicate that a minus error due to a pulsating flow, experienced in the conventional construction, is eliminated almost completely, and that a plus error due to a reverse flow is reduced to about 1/10.

摘要： An apparatus for controlling the operation of an internal combustion engine having a carburetor which, controls the air-fuel ratio of the air-fuel mixture supplied to the engine in the steady operating condition of the engine on the basis of predetermined data determined relative to the engine crankshaft rotation speed and intake vacuum and stored in a memory. A three-way catalyst purifies engine exhaust gases, and an output signal from an O.sub.2 sensor in the exhaust system is fed back for the control of the air-fuel ratio in the engine exhaust gases. A circuit checks whether this feedback control is normally carried or not. The air-fuel ratio supplied to the engine in an unsteady operating condition of the engine is controlled by regulating the fuel and air supplied to the engine while bypassing the carburetor, by the sensed values of the intake vacuum, engine crankshaft rotation speed and engine temperature and also depending on the throttle valve position. To control the rate of exhaust gas recirculation, an upper limit and a lower limit of the rate of opening of a recirculation rate regulating valve are determined on the basis of the sensed throttle valve opening, and other predetermined data determined relative to the engine crankshaft rotation speed and intake vaccum is read out from the memory to limit the rate of opening of the recirculation rate regulating valve.
