Abstract
Systems, methods, and computer readable storage media for controlling oxidation of a particulate filter (PF) are closed. The oxidation of the PF may be controlled using a PF model. The PF model may be utilized to simulate operations of the PF based on various input data and/or derived data to determine an optimum time for initiating an oxidation event at the PF, and an oxidation event may be initiated at the PF based on the simulating.
Claims20
A method for controlling oxidation of a particulate filter (PF), the method comprising:
- compiling, by a processor, input data for initializing a PF model;
- executing, by the processor, a simulation of the PF model based at least in part on the compiled input data, wherein the simulation of the PF model comprises:
- calculating soot characteristics representative of soot present in the particular filter;
- and
- determining a 3-dimensional (3D) temperate estimate for the PF based on the soot characteristics, information associated with physical characteristics of the PF, and one or more reaction parameters;
- and
- initiating an oxidation event at the PF based on the simulating.
A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations for controlling oxidation of a particulate filter (PF), the operations comprising:
- compiling input data for initializing a PF model;
- executing a simulation of the PF model based at least in part on the compiled input data, wherein the simulation of the PF model comprises:
- calculating soot characteristics representative of soot present in the particular filter;
- and
- determining a 3-dimensional (3D) temperate estimate for the PF based on the soot characteristics, information associated with physical characteristics of the PF, and one or more reaction parameters;
- and
- initiating an oxidation event at the PF based on the simulating.
A system for controlling oxidation of a particulate filter (PF), the method comprising:
- an engine;
- a particular filter (PF) configured to process at least a portion of exhaust generated by the engine;
- one or more sensors;
- a memory;
- and
- one or more processors communicatively coupled to the memory and the one or more sensors, the one or more processors configured to:
- compile input data for initializing a PF model based on information received from the one or more sensors;
- execute a simulation of the PF model based at least in part on the compiled input data, wherein the simulation of the PF model comprises:
- calculating soot characteristics representative of soot present in the PF;
- and
- determining a 3-dimensional (3D) temperate estimate for the PF based on the soot characteristics, information associated with physical characteristics of the PF, and one or more reaction parameters;
- and
- initiate an oxidation event at the PF based on the simulation.
