    摘要： A method of feedback control for an electronic fuel injection system in an internal combustion engine includes the steps of calculating a front O.sub.2 sensor switching voltage threshold based on a signal from a front O.sub.2 sensor upstream of a catalyst in an exhaust system for the engine and from a rear O.sub.2 sensor downstream of the catalyst, comparing a voltage output of the front O.sub.2 sensor to the calculated front O.sub.2 sensor switching voltage threshold to determine if a fuel/air ratio of the engine is rich or lean, and decreasing or increasing an amount of fuel to the engine by fuel injectors of the electronic fuel injection system if the fuel/air ratio is determined rich or lean, respectively.

    摘要： Many internal combustion engines have an auxiliary means for controlling airflow into the engine at idle, such as an Automatic Idle Speed (AIS) motor to compensate for changing load requirements. A method is disclosed for controlling the AIS motor and in turn engine idle speed to compensate for changing loads due to the operation of the air conditioner. The method recognizes the relationship between ambient temperature and pressures generated within the air conditioning compressor and the compensation necessary to maintain a smooth idle speed. The method also utilizes adaptive learning to relate a "looked up" of the air conditioner to the current value of auxiliary air flow required by a warmed up engine.

    摘要： The present invention is a method of firing fuel injectors for an engine of an automotive vehicle. The method includes the steps of determining whether injection timing for firing fuel injectors has changed from one predetermined state to another predetermined state of a distributor reference signal, firing the injectors for a predetermined time period and delivering a calculated amount of fuel for the one predetermined state if the injection timing has not changed. The method also includes determining whether a need for transition fuel has ended if the injection timing has changed and firing the fuel injectors for another predetermined time period and delivering a calculated amount of transition fuel at another predetermined state if the need for transition fuel has not ended. The method further includes firing the fuel injectors for another predetermined time period and delivering a calculated amount of fuel for the another predetermined state either after completion of the firing of transition fuel or if the need for transition fuel has ended.

    摘要： The present invention provides a method for determining ethanol thresholds for a flexible fuel control system for a motor vehicle capable of operating on more than one type of fuel. Preferably, the ethanol threshold is determined from an off-idle purge-free cell from a matrix of fuel adaptive memory cells normally used to compensate for car-to-car variations in required fueling. The ethanol threshold is periodically reduced to compensate for levels of alcohol creep indicated by the amount of purge-free adaptive memory elevation. If the learned value of percent alcohol content of the fuel is less than the ethanol threshold, gasoline operating parameters are implemented for the internal combustion engine. The off-idle purge-free cell also provides a basis for interpolating an on-board diagnostic (OBDII) ethanol threshold. As such, the OBDII monitors are only enabled if the learned value of percent alcohol content of the fuel is less than the OBDII ethanol threshold.

    摘要： A method is provided for monitoring the integrity of a fuel composition sensor in a flexible fueled vehicle. At ignition-on, the fuel composition sensor is tested for electrical and rationality viability. After ignition-on, the fuel composition is periodically, non-intrusively, tested for potential rationality errors. Should the non-intrusive testing indicate that a potential error exists, the fuel composition sensor is intrusively tested for rationality errors. If the intrusive test detects that the fuel composition sensor is malfunctioning, the engine control system converts to a limp-in mode and sets the engine operating parameters based on feedback from an exhaust gas oxygen sensor system.

    摘要： The present invention provides a flexible fuel compensation system for controlling operating parameters of an internal combustion engine based on a learned value of the percent alcohol content of the fuel using an oxygen feedback system. The methodology determines a fuel composition multiplier based on the percent alcohol content and implements gasoline operating parameters for the internal combustion engine if the fuel composition multiplier is less than a first threshold value, mixed gasoline/alcohol operating parameters if the fuel composition multiplier is greater than the first threshold value, and high concentration alcohol operating parameters if the fuel composition multiplier is greater than a second threshold value for a number of comparison checks. After a predetermined period, the fuel composition multiplier is updated and re-compared to the first and second thresholds and the appropriate one of the aforementioned operating parameters is implemented. A third update of the fuel composition multiplier is made if the determined fuel composition multiplier is less than the actual percent alcohol content of the fuel by more than a given amount.

    摘要： A method of controlling a vapor storage canister for a purge control system of an internal combustion engine is provided. The method includes the steps of determining if predetermined conditions are right for controlling a vapor storage canister and maintaining normal fuel feedback operation if the predetermined conditions are not right for controlling the vapor storage canister. The method also includes the steps of determining if the vapor storage canister is loaded if the predetermined conditions are right for controlling the vapor storage canister, maintaining normal fuel feedback operation if the vapor storage canister is not loaded and modifying a duty cycle of a purge solenoid to maximize purge if the vapor storage canister is loaded. The method further includes the steps of updating a loaded canister total purge multiplier and using the total purge multiplier to vary the amount of fuel being delivered to the internal combustion engine.
