摘要： Ignition timing for a combustion engine may be controlled by determining the roughness of current engine operation, comparing the determined roughness with a control roughness to determine if the determined roughness is within a threshold limit of the control roughness, and changing the ignition timing in a subsequent fuel delivery event as a function of the difference between the determined roughness and the control roughness. Preferably, the ignition timing is changed at least when the determined roughness is not within the threshold limit, although other factors may be taken into account when changing the ignition timing.

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 is provided for controlling spark advance based on a fuel modifier. Initially, engine fueling is reduced according to a known dynamic crankshaft fuel control (DCFC) methodology. As a result, the engine tends to run rougher. In response, spark advance is varied based on the overall fuel multiplier reduction from the DCFC methodology. For instance, a look-up table, or mathematical function based on the DCFC multiplier can be utilized as the basis for the spark advance.

摘要： A fuel control system is provided for enhancing the fueling strategy of a vehicle at start up when fueling is being supplemented with purge vapors from the fuel tank. The system includes monitoring the purge vapor flow rate from the purge vapor control system to the engine at start-up. A dynamic crankshaft fuel control fuel multiplier is then calculated based on engine roughness. If the engine is operating rough during purge vapor fueling, the amount of injected fuel is adjusted according to the fuel multiplier. Once oxygen sensor feedback is available, the dynamic crankshaft fuel control fuel multiplier is recalculated based on the oxygen sensor goal voltage. If necessary, the amount of injected fuel may be readjusted with the updated fuel multiplier. Once the engine is warm, the purge vapor fueling stops and the present methodology ends.

摘要： An exhaust system is provided including two catalysts and three oxygen sensors. The second catalyst is disposed downstream of the first catalyst. The first oxygen sensor is disposed upstream of the first catalyst, the second oxygen sensor is disposed downstream of the first catalyst and upstream of the second catalyst, and the third oxygen sensor is disposed downstream of the second catalyst. A goal voltage corresponding to a desired level of nitrous oxide and hydrocarbon within the exhaust is provided for the third oxygen sensor. This goal voltage is based on engine RPM and MAP. The engine controller compares the goal voltage to an actual voltage generated by sensing the level of oxygen downstream of the second catalyst. Based on this comparison, an error value between the goal voltage and the actual voltage is obtained. This error value is converted into a goal voltage for the first oxygen sensor. An actual voltage generated by the first oxygen sensor sensing the amount of oxygen upstream of the first catalyst is compared to the goal voltage derived from the third oxygen sensor. The difference between the goal voltage and actual voltage is used to modulate the pulse width of a signal sent to the fuel injectors of an engine such that the amount of fuel delivered by the fuel injectors is modified. The second oxygen sensor generates an actual voltage corresponding to the amount of oxygen the second oxygen sensor senses downstream of the first catalyst and upstream of the second catalyst. Changes in the actual voltage generated by the second oxygen sensor are compared to changes in the actual voltage generated by the first oxygen sensor. By monitoring the nature of theses changes as they relate to one another, the performance of the first catalyst can be determined.
