摘要： A pull-down resistor is connected to a power source line between power source connectors and a detector circuit in an apparatus in which a power source is connected via the power source connectors to the detector circuit, which includes a temperature-sensitive resistor and which outputs a voltage signal to a control unit via signal connectors. The pull-down resistor increases current flow to the power source connectors thus to suppress oxide formation thereon. A pull-up resistor or a pull-down resistor is connected to a signal line between the signal connectors and a filter circuit in the control unit, in order to increase an electric current that flows into the signal connector terminals thereby to prevent the formation of an oxide film on the signal connector terminals.

摘要： Discrimination is effected as to which of low-pressure and high-pressure conditions the pressure of fuel to be fed to a fuel injection valve is in. If in the low-pressure condition, the fuel injection pulse widths are corrected by assuming that the fuel pressure is a predetermined reference pressure, since the detection errors of a fuel pressure sensor are large. If in the high-pressure condition, the fuel injection pulse widths are corrected based on an actual fuel pressure detected by the fuel pressure sensor.

摘要： The heavy/light grade of fuel supplied to an internal combustion engine is detected, for example with a sensor or by detecting fluctuations in combustion pressure, and a retard angle correction amount for control of an ignition timing retard angle for activating an exhaust gas purification catalytic converter during a predetermined interval after engine start-up, is set based on the detected properties of the fuel. The time required for activating the exhaust gas purification catalytic converter can thus be shortened by retarding the ignition timing, corresponding to the heavy/light grade of the fuel, to increase the exhaust temperature while maintaining combustion stability.

摘要： The air/fuel ratio of an intake mixture of an internal combustion engine becomes excessively rich due to fuel leaked from the fuel injection valve into the intake system during a period from shut-down until restart. To overcome the resultant poor starting, the amount of leakage is estimated based on the engine temperature at shut down, and an elapsed time from shut-down until restart which is determined for example based on a difference between the engine shut-down temperature and the engine temperature at restart. The start-up fuel injection amount or the start-up intake flow rate is then corrected corresponding to this leakage amount.As a result, since a suitable start-up air/fuel ratio can be obtained in spite of fuel leakage from the fuel injection valve into the intake system, good engine starting can be ensured.

摘要： The open and close frequency of an intake control valve 30 for controlling an intake amount at an open and close time proportion, is variably controlled in accordance with engine rotational speed or elapsed time. As a result, during control of fuel vapor treatment, biased supply to a specific cylinder of fuel vapor drawn into the engine from an absorption device 29 is suppressed, so that an averaged air-fuel ratio can be obtained for each cylinder. Therefore, combustion variation between the cylinders can be avoided, the increased engine vibration due to the resultant increase in combustion pressure variation reduced, and the deterioration in exhaust composition and vehicle driving performance can be minimized.

摘要： Sucked air flow quantities are preliminarily alloted and stored for respective areas of predetermined ranges of the driving state of an engine, and every time a new sucked air flow quantity is detected, the stored value is renewed based on the previously stored value and the newly detected value. In the method and apparatus for detecting deterioration of a sucked air flow quantity-detecting device of an engine according to the present invention, the engine driving state is detected and the stored value of the sucked air flow quantity in the corresponding area is retrieved, the retrieved stored value is compared with the sucked air flow quantity actually detected by the detecting device, and deterioration is judged when the difference therebetween is larger than a predetermined value.

摘要： A fuel supply control system introducing the feature of learning in assuming or projecting an intake air flow rate while an engine driving condition is maintained in a sonic flow range, in which intake air path area is maintained substantially constant and intake air flow rate is varied linearly according to variation of an engine speed. The system also detects the engine driving condition in the sonic flow range and the engine speed maintained substantially constant to derive a basic fuel supply amount on the basis of boost pressure. The assumed intake air flow rate is derived on the basis of the basic fuel supply amount and the engine speed. The system derives the basic fuel supply amount on the basis of the assumed intake air flow rate and the engine speed when the engine speed varies within the sonic flow range.
