摘要： An apparatus for controlling the operation of an internal combustion engine having a carburetor, especially, the air-fuel ratio and the rate of exhaust gas recirculation, 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 previously in a memory. A three-way catalyst is used to purify 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 is provided to check whether this feedback control is normally carried or not. The air-fuel ratio of the air-fuel mixture supplied to the engine in an unsteady operating condition of the engine is controlled by regulating the amounts of fuel and air supplied to the engine while bypassing the carburetor, on the basis of the sensed values of the intake vacuum, engine crankshaft rotation speed and engine temperature and also depending on the throttle valve position. For the control of 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 vacuum is read out from the memory to limit the rate of opening of the recirculation rate regulating valve.

摘要： On an outer peripheral portion of a rotor (1), three protrusions are provided per each cylinder. A pickup coil 2 is disposed facing to the outer peripheral portion with a predetermined distance. A rotation signal (S.sub.0) is converted to a rotation signal pulse (S.sub.1) having three pulses (A, B and C) per each cylinder corresponding to the three protrusions. According to the first signal (A) of the rotation signal pulse (S.sub.1) the cranking ignition period (A.sub.1) is determined. According to the second signal (B) of the rotation signal pulse (S.sub.1), the starting timing for flowing current to the ignition coil (8) is decided. According to the third signal (C) of the rotation signal pulse (S.sub.1), the ignition timing at cranking operation is defined by detecting time intervals (3t, t, 2t) between the three signals (A, B, C).

摘要： A method of controlling the air-fuel ratio so as to be effectively maintained at a desired air-fuel ratio of .lambda.=1 is composed of a combination of an electronic map control for effecting the air-fuel ratio control on the basis of map data read out from a data map stored in ROM as air-fuel ratio control data in correspondence to various operation parameters of an engine and an O.sub.2 -feedback control for controlling the air-fuel ratio on the basis of oxygen quantity detected from the exhaust gas. Upon the occurrence of changes in the control quantity for a predetermined number of times in the course of the O.sub.2 -control, the latter is changed over to the map control. At that time point, a control quantity for the map control is corrected on the basis of a mean control quantity during the O.sub.2 -feedback control. Unless a significant variation takes place in the engine operating conditions, the map control is continued for a predetermined time and then changed over to the O.sub.2 -control. Upon the occurrence of a significant variation in the engine operating conditions, the map feedback control is immediately changed over to the O.sub.2 -control.

摘要： A cylinder fuel injection engine controller for controlling a cylinder fuel injection engine is capable of controlling the cylinder fuel injection engine for operation at a stable idling speed regardless of the variation of engine speed and load on the cylinder fuel injection engine while the cylinder fuel injection engine is cold and stratified combustion is impossible. The cylinder fuel injection engine controller comprises: a basic fuel injection quantity determining means for determining a basic fuel injection quantity (Tp1), a reference fuel injection quantity determining means for determining a reference fuel injection quantity (Tp2) from an engine speed and an accelerator pedal position; and a target fuel injection quantity calculating means for determining a target fuel injection quantity (Tp3) by multiplying the reference fuel injection quantity (Tp2) by a desired A/F ratio and dividing the product of the multiplication by the stoichiometric A/F ratio. The cylinder fuel injection engine controller is characterized by a reference fuel injection quantity adjusting means for adjusting the reference fuel injection quantity (Tp2) for engine speed control and/or load correction during idling operation. Fuel injection quantity (Tp) to be supplied to the engine and intake air quantity (Q) are controlled simultaneously and separately on the basis of the reference fuel injection quantity (Tp2).

摘要： An apparatus for purifying an exhaust gas emitted from an internal combustion engine, particularly, immediately after starting of the engine, includes a mechanism for reducing the time required to heat a catalyst converter to the activation temperature. The exhaust gas is passed through a preliminary catalyst close to the engine and then through a main catalyst downstream of the catalyst. The engine is operated with an air-fuel mixture which is richer than the amount indicated by the stoichiometric air/fuel ratio for a period of time from when engine is started until the main catalyst is heated to a temperature at which the catalyst can sufficiently perform its purifying capability. The preliminary catalyst is enabled to function at lower temperatures by combusting the exhaust gas which is generated during a rich air-fuel mixture condition. The main catalyst can be heated with the generated combustion heat, resulting in an enhancement in exhaust gas purifying capability.
