摘要： An approach and system for engine and aftertreatment system optimization. Emissions of an engine may be reduced by an aftertreatment mechanism. Control of the engine and the aftertreatment mechanism may be coordinated for the best overall efficiency relative to both fuel consumption and the emissions reduction. Engine and aftertreatment control may also be optimized in terms of cost function minimization. Individual efficiencies of the engine and aftertreatment mechanism are not necessarily significant by themselves. Therefore, the engine and aftertreatment mechanism should be controlled in a manner to achieve the optimality of the engine and the aftertreatment mechanism together as one entity.

摘要： Methods and systems are described for an engine with a SCR system including NOx sensors upstream and downstream of catalyst. One method includes monitoring SCR performance via calculating SCR conversion efficiency at different catalyst temperatures. Further, feedgas NOx levels are artificially increased when SCR device temperature is above a threshold to obtain more reliable readings from NOx sensors.

摘要： A control apparatus of an engine including intake and exhaust valves and a variable valve timing mechanism for varying open and close timings is provided. The apparatus includes a processor configured to execute an increasing amount controlling module for performing a fuel amount increase control in which a fuel injection amount is increased to decrease an exhaust gas temperature, and a valve controlling module for controlling, via the variable valve timing mechanism, an overlapping period in which the intake and exhaust valves are both opened on intake stroke. When the increasing amount controlling module performs the increase control, based on an increase of a temperature of the exhaust gas in the increase control, the valve controlling module determines whether a protection for an exhaust system component is required, and if the protection is determined to be required, the valve controlling module shortens the overlapping period.

摘要： Methods and systems are provided for detecting an air-fuel imbalance based on output from multiple degradation monitors. In one example, a method comprises, during feedback engine air-fuel ratio control responsive to output of an exhaust gas sensor positioned downstream of a catalyst, indicating a cylinder imbalance responsive to a catalyst transfer function determined only within a specified frequency range based on the exhaust gas sensor output after determining that the catalyst is nominal, and adjusting an actuator in response to the indicated cylinder imbalance. In this way, air-fuel ratio imbalances may be accurately identified and mitigated, thereby reducing emissions.

摘要： A vehicle includes a generator, an internal combustion engine for driving the generator, a catalytic device, and a controller for controlling the operation of the internal combustion engine. At a start of the internal combustion engine to allow the generator to start generating electricity, the controller, until the catalytic device reaches an activated state, operates the internal combustion engine in a warm-up mode such that the driving force of the internal combustion engine for driving the generator is below a value at which electricity is generated, and the controller, after the catalytic device reaches the activated state, operates the internal combustion engine in an electricity generating operating mode such that the driving force of the internal combustion engine is enhanced to the value at which electricity is generated to allow the generator to generate a predetermined quantity of electricity.

摘要： Methods and devices are described for performing engine diagnostics during skip fire operation of an engine while a vehicle is being driven. Knowledge of the firing sequence is used to determine appropriate times to conduct selected diagnostics and/or to help better interpret sensor inputs or diagnostic results. In one aspect, selected diagnostics are executed when a single cylinder is fired a plurality of times in isolation relative to a sensor used in the diagnosis. In another aspect, selected diagnostics are conducted while the engine is operated using a firing sequence that insures that no cylinders in a first cylinder bank are fired for a plurality of engine cycles while cylinders in a second bank are at least sometimes fired. The described tests can be conducted opportunistically, when conditions are appropriate, or specific firing sequences can be commanded to achieve the desired isolation or skipping of one or more selected cylinders.

摘要： An exhaust diagnostic system. The system includes a diesel engine having an exhaust system with a diesel particulate filter (DPF), a diesel oxidation catalyst (DOC), a selective catalytic reduction (SCR) catalyst, a first NOx sensor located upstream of the SCR catalyst and a second NOx sensor located downstream of the SCR catalyst. In addition, an engine control unit (ECU) is in electronic communication with the first NOx sensor and the second NOx sensor. An SCR coordinator can be included and be configured to execute a non-intrusive SCR deNOx efficiency test, an intrusive SCR/DOC deNOx efficiency test and an intrusive DOC non-methane hydrocarbon (NMHC) conversion efficiency test on the exhaust system. As a result of the conversion efficiency tests, a distinction can be made as to whether the SCR catalyst or DOC is failing.
