Abstract: Vehicle exhaust system uses delta pressure based estimation of accumulated soot within a diesel particulate filter. The exhaust system has a diesel oxidation catalyst and a diesel particulate filter. A fuel injector is connected upstream from the diesel oxidation catalyst and the diesel particulate filter. A delta pressure sensor measures difference in pressure at inlet and outlet of the diesel particulate filter. A controller determines when to regenerate the diesel particulate filter based on an estimated amount of soot. The controller, in a first regeneration mode, causes the fuel injector to inject fuel at a first rate into the exhaust stream, and to re-evaluate amount of soot accumulated within the diesel particulate filter under increased volumetric flow. The controller, in a second regeneration mode, causes the fuel injector to inject fuel at a second rate into the exhaust stream in order to combust soot trapped in the diesel particulate filter.

Abstract: A gas turbine engine has an accessory gearbox disposed outside of a bypass channel and connected to a housing part, which radially delimits the bypass channel, in a connection region near the housing part and in a connection region far from the housing part. A connecting element is provided between the housing part and the connection region far from the housing part. A longitudinal axis of the connecting element includes an angle in the range of 75° to 115° with a vertical axis of the accessory gearbox. The connecting element can vary a distance between the far connection region and a connection point of the connecting element on the housing part such that deformation of the housing part and a resulting position change of the connection point cause a lesser deflection of the accessory gearbox than a deflection with an unchanged length of the connecting element.

Abstract: Aspects of the disclosure relate to providing an EGR cooler including a barrier layer applied to EGR cooler components while allowing sufficient heat transfer between exhaust gases and the cooling medium. A barrier layer may be applied onto particular surfaces of the EGR cooler components to prevent deposition of hydrocarbons or soot on the EGR cooler components. In some arrangements, the barrier layer may comprise a refractory solid oxide. In other arrangements, an EGR cooler may comprise a catalytic barrier layer. The catalytic barrier layer may include a refractory solid oxide and a platinum group metal or mixed metal oxide to prevent accumulation of varnish material deposited onto EGR cooler components.

Abstract: Diesel Exhaust Fluid is metered into an engine exhaust gas aftertreatment system having a close coupled SCR catalyst and a main SCR catalyst. The DEF is injected into two injector locations, one upstream of the close coupled SCR catalyst and another upstream of the main SCR catalyst, the quantity of DEF in each injector being based on primarily the temperature at the main SCR catalyst and the mass flow of the NOx through the aftertreatment system. This method of injection enables a relatively better fuel economy outcome while meeting the regulated tailpipe NOx emission levels and the N2O formation limits.

Abstract: A DEF injector is connected to the exhaust system of a vehicle upstream of an SCR catalyst, and is further connected to the ECU or DCU. An exhaust temperature sensor and an exhaust mass flow rate sensor are connected to the ECU or DCU, and further connected to the DEF injector. The ECU or DCU controls the DEF injector based on exhaust temperature and exhaust mass flow rate when the exhaust temperature is above a certain threshold. The DEF injector itself, or a dedicated DEF injector controller, overrides and/or supplements the control logic located within the ECU or DCU to control the DEF injector to inject DEF at reduced rates when the exhaust temperature and/or the exhaust mass flow rate are lower than the threshold for DEF injection set by the ECU or DCU.

Abstract: A virtual diesel exhaust fluid (DEF) quality monitor repeatedly performs an intrusive test for disclosing use of adulterated DEF by injecting a controlled quantity of DEF into a diesel engine exhaust aftertreatment system upstream of an SCR catalyst while the engine operates and then processing certain data obtained from the test.

Abstract: A system includes one or more “BotMagnet” modules that are exposed to infection by malicious code. The BotMagnets may include one or more virtual machines hosing operating systems in which malicious code may be installed and executed without exposing sensitive data or other parts of a network. In particular, outbound traffic may be transmitted to a Sinkhole module that implements a service requested by the outbound traffic and transmits responses to the malicious code executing within the BotMagnet. In the case of shellcode attacks, unsuccessful attacks may be emulated by selecting a corresponding emulator that will receive and execute instructions, as would a successful shellcode attack. Events occurring on the BotMagnet and Sinkhole are correlated and used to characterize the malicious code. The characterization may be transmitted to other computer systems in order to detect instances of the malicious code.

Each scan list includes individual entries. Each individual entry specifies a WiFi access point network identifier collected by a client. WiFi access point networks in the scan lists are evaluated. WiFi access point handshake priorities are supplied to the client devices. The WiFi access point handshake priorities characterize WiFi access point recovery and discovery priorities.
