摘要： A method for adjusting fuel injection of an engine is disclosed. In one example, fuel injection timing is adjusted to account for fuels having different cetane numbers. Operation of the engine may be improved especially during conditions where combustion phase may vary.

摘要： A system for improving operation of an engine having a particulate matter sensor is presented. The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, particulate sensor degradation is indicated in response to an output of said particulate matter sensor staying below a threshold as engine temperature increases past the dewpoint temperature.

摘要： A method of operating an engine system is described in which a back-pressure valve of a low pressure EGR system can be modulated at a lower frequency during an EGR operation, and at a higher frequency when additional exhaust gas sensing is requested. Back-pressure valve modulation can therefore be used to promote exhaust gas mixing while providing EGR. Exhaust gas constituents in the mixed exhaust gas can then be sensed with higher accuracy by downstream exhaust gas sensors.

摘要： A method for diagnosing a particulate matter sensor is described. In one example, a liquid is purposefully injected into the exhaust system to verify operation of the particulate matter sensor. Reliability of particulate matter diagnostics may be improved by way of the approach, at least during some conditions.

摘要： A system for improving operation of an engine having a particulate matter sensor is presented. The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, degradation of a particulate matter sensor is indicated after a temperature of a substrate of the particulate matter sensor exceeds a threshold temperature and an output of the particulate matter sensor is below a threshold value.

摘要： A method for controlling a particulate matter sensor heater is provided. The method includes operating the heater to burn-off soot accumulated on the sensor; and adjusting the heater level based on sensor output generated during the heater operation. In this way, improved heater control can be achieved using the sensor output already available.
