Methods and systems for reducing emissions of an internal combustion engine are described. In one example, a combustor is applied post shutdown to purge stored NOx from a passive NOx absorber to prepare for a subsequent engine start. The trapped NOx is subsequently reduced via a selective catalytic reduction catalyst.

Engine cold start system and method

Methods and systems for reducing emissions of an internal combustion engine are described. In one example, an electric heater and a selective reduction catalyst are positioned in a passage downstream of a combustor where urea may be injected to the selective reduction catalyst to reduce NOx emissions that may be generated by the combustor.

System and method for engine cold start

Methods and systems for reducing emissions of an internal combustion engine are described. In one example, an electric heater and a passive NOx absorber or other emissions control device are positioned in a passage downstream of a combustor so as to process emissions from the combustor before an engine is started.

A method for determining the presence of water and diesel exhaust fluid mixed with diesel fuel is disclosed. In one example, output pressure of a fuel pump may be indicative of the presence or absence of water in diesel fuel. The presence or absence of water in fuel may be evaluated in response to filling a fuel tank.

Method and system for water in fuel prognostic monitor

Methods and systems for operating an engine that includes two fuel pumps are described. In one example, a first fuel pump may be activated or remain activated in response to an engine shutdown request so that a second fuel pump may be cooled before the first fuel pump is deactivated in response to the engine shutdown request.

System and method for fuel pump shutdown

A diesel engine system includes an engine, an exhaust system connected to the engine, and a water-fuel separator. The exhaust system has an aftertreatment device, an exhaust pipe upstream of the aftertreatment device, and a fuel injector connected to the exhaust pipe. The water-fuel separator has a filter configured to separate water from fuel and a reservoir configured to store the separated water. The reservoir is in fluid communication with the fuel injector.

Automatic draining of water-fuel separator via downstream injection system

Methods and systems are provided for increasing EGR delivered to an engine. In one example, a method may include determining an EVO timing set point and an external EGR setpoint in parallel, based on an inverse model. The EVO timing may be adjusted based on a combination of the EVO timing setpoint and an EGR cylinder balancing feedback loop, thereby varying internal EGR to the engine to supplement external EGR.

Valve timing modulation for EGR balancing

Methods and systems are provided for controlling and monitoring intake and exhaust poppet valves of an internal combustion engine. In one example, the methods and system include feedback control that estimates intake and exhaust valve timing based on output of an in cylinder pressure sensor. In another example, the methods and system include compensation for feedforward control of intake and exhaust valves based on output of the in cylinder pressure sensor.

Methods and systems for engine valve timing or lift adjustment

Methods and systems are provided for improving turbocharger response in a boosted engine. In one example, a current turbocharger performance may be monitored, if meeting and operating in an optimum region for efficiency (e.g., on compressor and/or turbine maps), engine may be operated with a steady state exhaust valve opening (EVO) timing in an optimum position based on engine mapping (e.g., engine pumping work). Otherwise, the EVO timing may be advanced (opening earlier) to release more energy into the exhaust or retarded to release less, to move turbocharger to desired performance. By adjusting EVO timing to achieve desired turbocharger response and performance, faster response is achieved.

Methods and systems for a boosted engine

Methods and systems for operating an engine that includes an after treatment system are described. In one example, traffic data and navigation system data are a basis for deciding whether or not to increase heat output of an engine to ensure operation of the after treatment system. In particular, one or more actuators may be adjusted to minimize fuel consumption and/or reduce feedgas emissions while generating sufficient heat to maintain after treatment system operation.

System and method for previewing vehicle emissions

Methods and systems are provided for a vehicle wirelessly communicating with a central server. In one example, a method may include monitoring faults and sending engine conditions along with driver inputs to the central server for processing.

Method for sharing and receiving vehicle fuel quality alerts

Methods and systems are provided for identifying when an exhaust valve of an engine cylinder is not functioning as desired while the engine is being operated to raise a temperature of an exhaust system emissions control device, and in turn taking mitigating action. Thus, in one example a method comprises adjusting an amount of fuel that is provided to each of a plurality of cylinders of an engine during an exhaust stroke of the engine in response to an indication of degraded combustion stemming from a cylinder of the engine. In this way, the engine may continue to be operated to raise the temperature of the exhaust system emissions control device, while mitigating the issue of the degraded combustion.

Systems and methods for reducing exhaust valve degradation

Methods and systems are provided for calculating a fuel aging of fuel in a fuel tank. In one example, a method may include alerting a vehicle operator and/or adjusting engine operating parameters in response to a fuel aging being greater than a threshold aging.

Methods and systems for determining fuel quality

Methods and systems for operating an engine and determining relative compression ratio differences from a reference cylinder are disclosed. In one example, an engine is rotated via a starter or another type of electric machine and engine deceleration rates related to each engine cylinder are determined. The engine deceleration rates form a basis for compression ratio factors for each engine cylinder.

System and method for estimating cylinder pressures

Methods and systems are provided for estimating maximum in-cylinder pressure for all engine cylinders while reducing the number of individual cylinders required for pressure sensing. Pressure sensing is performed for a single instrumented cylinder. For remaining non-instrumented cylinders, an engine speed-dependent correction factor is applied that compensates for compression pressure variation between cylinders due to intake valve closing differences.
