The invention relates to a receptacle container for supplying a fluid into a body or body component having a connected monitoring unit in order to monitor a fluid reaction.

The present invention relates to a ferritic stainless steel according to the present invention, containing, in mass %: 0.001%C0.020%, 0.05%Si0.50%, 0.1%Mn1.0%, 15.0%Cr25.0%, Mo<0.50%, 0.50%W5.00%, and 0.01%Nb0.50%, with a balance being Fe and unavoidable impurities, having a content (coarse Laves phase ratio) of coarse Laves phase having a diameter of 0.50 m or more being 0.1% or less, and having an average grain size being 30 m or more and 200 m or less.

A sealing assembly for a sensor port of a double-walled muffler. The assembly includes at least an outer plate and a washer-type element. The washer-type element has a planar portion provided with an aperture, and a tube portion protrudes from an edge of the aperture. The assembly is mounted on a sensor port provided with a boss fixed to an inner wall of the double muffler wall, and with an opening in an outer wall surrounding the boss. The tube portion is fitted over the boss, and the assembly is fixed to the outer wall. Any radial or lateral movement of the boss relative to the outer wall is able to take place without losing sealing function, due to lateral freedom of movement of the washer-type element relative to the outer plate, and due to the fact that the boss is able to move relative to the tube portion.

The invention relates to a process, consisting in cooling at least one component, such as a sensor, arranged within a compartment of an exhaust after treatment system of a vehicle. The exhaust after treatment system comprises a cooling system that is activated during active regeneration of one or more particulate filters arranged within the exhaust after treatment system compartment and that includes a pipe, for blowing fresh air on the component to be cooled or for extracting hot air present at the vicinity of the component to be cooled, so that said component is protected as a priority against high temperatures during active regeneration periods.

A fluid sensor including a guide, a float, a permanent magnet, and a magnetic angle sensor. In one example, the float is constrained at least in part by the guide to move along a vertical axis. The permanent magnet is mechanically coupled to the float. The magnetic angle sensor is configured to measure an angle of a magnetic field generated by the permanent magnet and is positioned such that movement of the float along the vertical axis varies the angle of the magnetic field generated by the permanent magnet through the magnetic angle sensor.

A system for detecting a characteristic of a fluid. In one example, the system includes a tube, a float, a sensor, and a controller. The tube is configured to receive the fluid. The float is located within the tube. The sensor is configured to sense a position of the float. The controller is configured to receive, from the sensor, the position of the float, and determine a characteristic of the fluid based on the position of the float. The characteristic may be a density or a concentration.

A controller for controlling regeneration in an aftertreatment system comprising a first leg and a second leg is configured to: determine whether regeneration is permitted by the engine based on engine operating parameters; in response to regeneration being permitted, determine whether regeneration is required in at least one of the first leg or the second leg based on operating parameters of the first leg and the second leg, and whether regeneration is inhibited in either the first leg or the second leg; and in response to determining that (i) regeneration is required in at least one of the first or second leg, and (ii) regeneration is not inhibited in either the first or the second leg, cause insertion of hydrocarbons into the engine to thereby increase the temperature of the exhaust gas to a target temperature and cause regeneration in each of the first and second leg.

A system includes an emissions control system. The emissions control system includes a processor programmed to receive one or more selective catalytic reduction (SCR) operating conditions for an SCR system. The SCR system is included in an aftertreatment system for an exhaust stream. The processor is also programmed to receive one or more gas turbine operating conditions for a gas turbine engine. The gas turbine engine is configured to direct the exhaust stream into the aftertreatment system. The processor is further programmed to derive a NH.sub.3 flow to the SCR system based on an SCR model and the one or more SCR operating conditions, to derive a NO/NOx ratio, and to derive a fuel split for the gas turbine engine based on the NH.sub.3 flow, the NO/NOx ratio, or a combination thereof.

A connection piece assembly unit, especially for an exhaust gas treatment device of an exhaust system of an internal combustion engine, includes a connection piece (30) with a base area (32) for fixing the connection piece (30) to a carrier assembly unit. A covering element (40) projects over an outside (42) of the connection piece (30).

A radio frequency system and method for monitoring an engine-out exhaust emission constituent. The system comprises a housing containing the emission constituent, one or more radio frequency sensors extending into the housing and transmitting and receiving radio frequency signals, and a control unit for controlling the radio frequency signals and monitoring changes in the emission constituent based on changes in one or more parameters of the radio frequency signals. In one embodiment, the control unit measures a rate of change in one or more of the parameters of the radio frequency signals for monitoring a rate of change of the emission constituent including for example the emission rate, accumulation rate, and/or depletion rate of the emission constituent.
