Abstract:
A method for regenerating a diesel particulate filter () in the exhaust system () of an engine (). When a request to regenerate the device is issued, a control system () operates the engine to begin conditioning exhaust. The conditioning process comprises a warming phase that occurs prior to initiation of regeneration and a heating phase during which regeneration can occur. During the process, data related to the warming phase and the heating phase is evaluated. The engine is operated to terminate the process prior to having reduced the amount of trapped particulate matter to a target amount when evaluation of the data discloses that the process should be terminated.
System And Method For Calculating Loading Of A Diesel Particulate Filter By Windowing Inputs
An algorithm () in an engine control system () develops data indicative of pressure across a DPF () as a function of time and data indicative of flow rate through the DPF as a function of time, calculates derivatives () () with respect to time of the data, processes the derivatives () to confirm validity of a calculation of particulate loading of the DPF (load_pf) when a result of processing the derivatives discloses the absence of transient conditions in the DPF that would prevent the calculation from being valid and to not confirm validity of a calculation of particulate loading of the DPF when a result of processing the derivatives discloses the presence of transient conditions in the DPF that would prevent the calculation from being valid.

International Classification:
F01L001/34
US Classification:
123/090150
Abstract:
A system and method for determining an estimation of actual cam phase angle of increased accuracy are based on an observed cam phase angle derived from a cam phase sensor and a predicted cam phase angle derived from a desired or commanded cam phase angle. The estimated cam phase angle is used in the electronic control unit in computing desired settings for engine variables which depend on cam phase angle.

Abstract:
A urea injection control system () for a vehicle having an exhaust line () in fluid communication with a SCR catalyst () and a urea injector () for injecting urea into the exhaust line includes a controller () for controlling the flow rate of urea injection at the urea injector. The controller () compares an optimum urea flow rate () with a flexible urea flow rate () determined by a flexible flow rate calculator. The controller () selects the minimum value of the optimum urea flow rate () and the flexible urea flow rate (), and controls the urea injector () to inject urea at the minimum value.

Abstract:
A method of controlling a variable geometry turbocharger is provided. A predefined desired boost pressure of a turbocharger is obtained from a memory. A predefined desired mass flow rate in an intake manifold of an engine is obtained from the memory. A theoretical amount of power required by the turbocharger to generate the desired boost pressure and the desired mass flow rate is calculated. An actual mass flow rate in the intake manifold is determined. An actual amount of power required by the turbocharger to generate the desired boost pressure and the actual mass flow rate is calculated. At least one adjustable vane of the turbine of the turbocharger is adjusted to allow the theoretical amount of power required of the turbocharger to generally equal the actual amount of power by adjusting the boost pressure.

Abstract:
A method of controlling an engine based upon airflow is provided. A request for a desired torque output of the engine is received. A first amount of fuel required to generate the desired torque is retrieving from a memory. An amount of airflow required to combust the fuel required to generate the desired torque at a predefined air/fuel ratio is calculated. A first amount of EGR required to produce a predefined amount of NOx emissions is calculated. The amount of airflow required to the first amount of EGR required is added. The total of the airflow and the first amount of EGR are compared to a volume available in a cylinder. At least one of the first amount of fuel delivered and the first amount of EGR provided is modified when the total of the airflow and the EGR exceeds the total volume available in the cylinder.
Apparatus And Method For A Mobile Water-Based Cooking System
A water-based cooking apparatus onboard a vehicle includes a cooking bay and a controller. The cooking bay can be sealed with a lid so that water does not escape the cooking bay when the vehicle is in motion. The controller receives, from a computing device onboard the vehicle, cooking instructions including commands operable to perform one or more of filling the cooking bay with water, setting a temperature for the cooking bay, and adjusting a salinity of water in the cooking bay. The computing device can display cooking instructions on a display and can send status reports to a remote command center.
