    摘要： An improved engine fuel control detects combustion instability due to the use of high DI fuel during cold start and warm-up and compensates the fuel control for detected combustion instability through temporary enrichment of the delivered air/fuel ratio. When the engine idle speed error magnitude is less than a calibrated threshold, usage of high DI fuel is detected by identifying a surge signal based on the engine speed error fluctuation in a predetermined frequency range attributable to combustion instability due to the presence of high DI fuel in a cold engine. When the average amplitude of the surge signal exceeds a calibrated surge threshold, the presence of high DI fuel is detected. Additionally, the method is disabled for a prescribed period following commanded load transitions associated with the air conditioning system and the automatic transmission.

    摘要： An improved engine fuel control detects combustion instability due to the use of high driveability index (DI) fuel during cold start and warm-up and compensates the fuel control for detected combustion instability through temporary enrichment of the delivered air/fuel ratio. The usage of high DI fuel is detected during engine cranking by measuring the time required for the engine speed to increase from a lower reference speed to an upper reference speed, provided the engine run time is less than a calibrated value. A timer is started when the lower reference speed is achieved, and the timer value is compared to a crank time threshold determined as a function of the initial engine coolant temperature. If the timer value exceeds the crank time threshold before the engine speed reaches the upper reference speed, the presence of high DI fuel is indicated, and the air/fuel ratio is temporarily enriched.

    摘要： A combined bearing/diaphragm seal for use in a solenoid valve assembly or the like is disclosed which provides a flexible fluid seal between the solenoid sub-assembly and the valve sub-assembly. The solenoid and valve sub-assemblies communicate mechanically via a portion of a solenoid armature which translates through the combined bearing/diaphragm seal and controls elements of the valve sub-assembly for regulating outlet fluid pressure. The bearing portion of the combined bearing/diaphragm seal comprises a flat spring-plate that is adapted to resiliently deflect in response to movement of the solenoid armature. The diaphragm portion of the combined bearing/diaphragm seal is an elastomeric seal material applied to at least one side of the spring plate.
