摘要： An air/fuel control system (8) and method for an engine (28) having two engine banks coupled to a single catalytic converter (50) uses first and second exhaust gas oxygen sensors (44, 55) coupled to respective first and second exhaust manifolds (56, 57) and various engine operating parameters. During a first set of engine operating conditions, air/fuel control system (8) maintains the exhaust air/fuel ratio oscillations of the two bank in phase with one another. During a second set of engine operating conditions, air/fuel control system (8) maintains the exhaust air/fuel ratio oscillations of the two bank 180 degrees out of phase with one another. When transitioning, emission impacts are minimized.

摘要： A method is presented for diagnosing a condition in the fuel vapor purge system. The engine, the fuel tank and the carbon canister are connected in a three-way connection. The engine can be selectively isolated by a purge control valve, and the fuel tank can be selectively isolated by a fuel tank control valve. The operation of both valves is coordinated by an electronic engine controller. By isolating the fuel tank, and comparing the actual rate of change of the internal tank pressure (from the tank pressure sensor) to the estimated rate of change (from engine operating conditions) it is possible to determine if a condition occurred, and whether it is in the tank or in the vapor purge lines.

摘要： A system and method for adjusting fuel vapor delivery from a fuel vapor recovery system in an internal combustion engine. An engine controller calculates a purge fuel fraction that is indicative of an amount of fuel vapor passing through the vapor recovery system relative to a total amount of purge flow, including air, passing through the vapor recovery system. A purge percent fuel parameter indicative of an amount of fuel vapor delivered to the engine from the fuel vapor recovery system relative to a total amount of fuel delivered to the engine is calculated based on the purge fuel fraction. Finally, the controller adjusts an amount of fuel vapor released from the vapor recovery system based on the purge percent fuel parameter.

摘要： A method for updating an air flow ratio of a current engine load to a maximum engine load includes calculating an approximate air flow ratio based only on throttle position changes. The approximate air flow ratio is calculated by modifying a normal, conventionally calculated air flow ratio based on a difference between two throttle position loads. The throttle position loads are ratios between sampled throttle positions and a reference throttle position. By approximating the air flow ratio rather than conducting an exact calculation, the invention method can update the air flow ratio to reflect changes in throttle position without adding significant chronometric burden.

摘要： A system and method for adjusting fuel vapor delivery from a fuel vapor recovery system in an internal combustion engine. A requested amount of fuel vapor delivery is determined based upon a desired fuel vapor delivery amount and various system constraints, which ensure continued optimal operation of the vehicle. Purge fuel ratios are calculated by comparing desired levels to actual levels of various operating parameters. The purge fuel ratios are compared to each other to determine the minimum value from among the various purge fuel ratios, which is indicative of the most limiting system constraint. The most limiting system constraint is used to calculate an amount of fuel vapor to be delivered from the vapor recovery system.

摘要： A method is provided for monitoring an emission device coupled to an engine. In one example approach, the method comprises: following a deceleration fuel shut-off duration, indicating degradation of the emission device based on an amount of rich products required to cause a sensor to become richer than a threshold. The amount of rich products required may be correlated to an amount of oxygen stored in the emission device. The indication of emission device degradation may be further based on air mass and temperature during delivery of the required rich products.

摘要： A method for selecting one of first and second cylinder groups of an internal combustion engine is provided. The first and second cylinder groups are coupled with first and second catalytic converters, respectively. The method includes identifying one of the first and second catalytic converters by comparing first and second catalyst parameters, associated with the first and second catalytic converters, respectively, to one another. The first and second catalyst parameters indicate which one of the catalytic converters is more capable of maintaining reduced emissions while adjusting an engine operational parameter. The method further includes selecting one of the first and second cylinder groups coupled to the identified catalytic converter for changing an engine operational parameter in the selected cylinder group.
