摘要： A more precise method for determining the oxygen storage capacity of an exhaust gas aftertreatment device is presented. The most accurate capacity estimate is obtained while the engine is idling or during low load operation. The capacity is determined by integrating the output of an oxygen sensor located downstream of the device during a period of time that it takes to store more than a predetermined amount of oxygen in the device. The overall LNT efficiency can then be inferred from its oxygen storage capacity. This method allows for improved emission control and fuel economy.

摘要： Various systems and method for heating an engine in a vehicle during a cold start are described. In one example, thermal efficiency of the engine is improved by heating engine coolant via a high-pressure exhaust gas recirculation (HP-EGR) system. For example, after light-off of an exhaust catalyst, exhaust gas is routed through the HP-EGR system which includes a HP-EGR cooler. Heat from the exhaust gas is then used to warm the engine coolant via the HP-EGR cooler.

摘要： An engine diagnostic system for use with an internal combustion engine coupled to a lean NOx trap with a sensor coupled downstream of the trap. The sensor provides two output signals, one indicative of an air-fuel ratio and the second indicative of a NOx concentration. Construction of the sensor insists that proper indication of NOx concentration is dependent upon proper operation of the first output signal. Degradation of the NOx concentration signal is determined when the first output signal has degraded.

摘要： A method is described for controlling fuel vapor purging and adaptive learning in a lean burn engine system. Fuel vapor purging is carried out during lean operating conditions to minimize impact on vehicle emissions, while adaptive learning is carried out during near stoichiometric conditions (oscillations around stoichiometry). This allows faster fuel vapor purging and additional adaptive learning opportunity.
