摘要： A circuit and method are provided for heating a dual heater oxygen sensor. One resistance element is of relatively low resistance such that the oxygen sensor is heated quickly and the other element is of relatively high resistance such that the oxygen sensor is heated and maintained at an optimal operating temperature. The circuit and associated method turn on a low resistance start heater that is in communication with the oxygen sensor given start-up conditions. Once the oxygen sensor has reached an operating temperature range a high resistance operating temperature heater is turned on and the start heater is turned off.

摘要： A method for pulse width modulating a resistance element of an oxygen sensor. The method quickly heats the resistance element of the oxygen sensor soon after start of the engine with a relatively high duty cycle yielding wide pulse widths. During a mid oxygen sensor temperature range, the method decreasing the duty cycle and thereby the pulse width modulation. And, upon the oxygen sensor reaching peak operating temperature range, the method decreases the pulse width modulated voltage signal supplied to the oxygen sensor to relatively short duty cycled pulses.

摘要： A method of adapting a linear EGR system is provided to adjust flow rates based on engine roughness. Initially, the level of engine combustion roughness is measured and quantified by a known dynamic crankshaft fuel control methodology. In response, the method adjusts the EGR valve desired position higher or lower based on the measured combustion roughness. For example, if the engine is running "smooth", then more EGR is used. If the engine is running "rough", less EGR is used. As the engine approaches a roughness target, the EGR is stabilized.

摘要： A method for improving the transient response of a multi-port fuel injection system wherein the delivery of a pulse to an injector is fragmented into a variable number of pulse fragments and the delivery of the pulse fragments to the injector is spaced throughout a respective fueling window. The magnitude and delivery angle of each of the pulse fragments is variable and depends upon the current engine operating conditions. Calculations of the magnitude of each pulse fragment are based upon a constantly recalculated total pulse width.

摘要： A method is provided for accommodating the purge vapors from an evaporative emission control system of an automotive vehicle. The method includes a means of learning changes in the mass of a purge vapor collection canister such that a mass of purge vapor in the canister can be determined. The canister model uses the output of a strategic adaption routine to learn the loading of the canister. Thereafter, the canister model uses the learned loading of the canister and tank flow rate from a tank model to compute the mass balance of purge vapor exiting and entering the canister. The concentration level is compared to the calibrated maximum in an open loop surface to determine the level of canister loading. Based on the current loading of the canister, the open loop surface of canister concentration as a function of flow rate and accumulated flow is used to predict how the concentration will change as the flow rate through the canister changes. As such, the fuel to air ratio delivered through the injectors can be adjusted in real time to improve drivability and emissions.

摘要： A method is provided for accommodating the purge vapors from an evaporative emission control system of an automotive vehicle. The method includes a means of predicting the concentration of purge vapor at the purge valve of the evaporative emission control system as a function of purge flow and accumulated flow through the canister. Purge valve flow is characterized by using a surface for air mass flow rate as a function of vacuum at the purge valve and purge valve current. The flow through the valve is used to compute instantaneous flow rate and accumulated flow rate. As such, the fuel delivered through the injectors can be adjusted in real time to improve drivability and emissions by maintaining a desired fuel to air ratio.
