    摘要: An EGR valve position control method controls a position of an EGR valve according to a pressure change across the valve and a desired EGR valve position. The method calculates a desired EGR valve position and generates one or more duty cycle control terms based on a difference between the desired EGR valve position and an actual EGR valve position. Additionally, the method provides feedforward control based on the pressure change and the desired EGR valve position in order to generate feedforward duty cycle control terms. The method controls the position of the EGR valve based on the duty cycle control terms.

    摘要: A power steering load compensation system for an internal combustion engine which employs a pressure sensor to monitor the output pressure of the power steering pump. The pressure sensor provides an input signal to an engine controller, and the engine controller generates an automatic idle speed output signal for controlling the idle speed motor of the engine throttle body. By varying the air flow through the throttle body in accordance with output pressure of the power steering pump, which varies with the pump load placed upon the engine, dips and surges in engine revolutions per minute (RPM) at idle and low speeds may be substantially reduced.

    摘要: The present invention overcomes these problems by providing an oxygen sensor located in the exhaust stream of an internal combustion engine, a load sensing device which generates a signal indicative of an internal combustion engine load, a central processing unit which calculates a running average of the oxygen content in the exhaust stream indicated by the oxygen sensor and a fuel injection device which supplies fuel to the combustion air in response to the central processing unit. The central processing unit uses the running average of the oxygen content in the exhaust stream, in lieu of the instantaneous oxygen content, to modify the fuel equation for determining the proper air fuel mix when transitioning from closed to open loop operation. The resulting air fuel mixture thus reflects the average oxygen value in the exhaust over a period of time. This average serves to cancel out the extreme surplus and deficiency of oxygen in the exhaust stream due to dithering.
