Abstract: Exhaust generated from an internal combustion engine includes particulates and gas-phase volatile hydrocarbon condensables. The exhaust is cooled in an exhaust gas cooler from a first temperature to a second temperature such that a first portion of the gas-phase volatile hydrocarbon condensables in the exhaust condense to the liquid phase and a second portion of the gas-phase volatile hydrocarbon condensables in the exhaust condense on black carbon particles to form semivolatile brown carbon particulates. Some or all of the liquid-phase volatile hydrocarbon condensables and the semivolatile brown carbon particulates are trapped in a gasoline particulate filter or a catalyzed gasoline particulate filter located downstream of the exhaust gas cooler.

Abstract: Provided is a method for controlling a vehicle exhaust gas treatment system, wherein the system includes an engine and a selective catalytic reduction device configured to receive exhaust gas from the engine and reductant from an injector. The method comprises determining a need for a reductant injection, determining a need for reductant injector noise abatement, and subsequently conducting one or more reductant injection events during one or more engine combustion events. A vehicle combustion event comprises combustion of fuel within a cylinder of the ICE. Determining a need for reductant injector noise abatement comprises determining if an engine speed is below a threshold, if a speed of the vehicle is below a threshold, if a decibel level of a vehicle audio system is below a threshold, or if a hands-free telephone system is being utilized by a passenger of the vehicle. The engine can be a diesel engine.

Abstract: Systems and methods for controlling a valve for directing an exhaust gas stream through an exhaust duct having a first after treatment device and a second after treatment device in an exhaust system. The method includes receiving sensor signals from a sensor coupled to the second after treatment device. The method includes processing the sensor signals to determine a temperature of the second after treatment device, and determining a position for the valve based on whether the temperature exceeds a pre-defined threshold for the temperature of the second after treatment device. The method includes outputting a control signal to move the valve to a first position in which the exhaust gas stream flows through a first portion of the first after treatment device or a second position in which the exhaust gas stream flows through a second portion of the first after treatment device based on the temperature.

Abstract: Technical solutions are described for an emissions control system for a motor vehicle including an internal combustion engine. The emissions control system includes a reductant injector device, a selective catalytic reduction (SCR) device, and a controller. The controller determines a reductant energizing time for the reductant injector device based on one or more operating conditions of the SCR device. The controller further computes a diagnostic adaptation factor for the reductant energizing time based on an on-board diagnostic signal. The controller further inputs an amount of reductant into the SCR device by adjusting a reductant energizing time of the reductant injector device according to the diagnostic adaptation factor.

Abstract: A power generating set includes an engine operable in response to a flow of fuel to produce a flow of exhaust gas, a generator coupled to the engine and operable in response to operation of the engine to produce a total electrical power, and a primary load electrically connected to the generator to receive a portion of the total electrical power, the primary load having a cyclical pattern. A battery bank is selectively connected to the generator to receive a portion of the total electrical power and an insulated-gate bipolar transistor (IGBT) is positioned to selectively transition between a connected state and a disconnected state. The battery bank is connected to the generator to charge the battery bank when the IGBT is in the connected state and is disconnected from the generator when the IGBT is in the disconnected state.
