摘要： A DEF injector is configured to inject DEF into an exhaust system of a vehicle. A DEF pump includes an electric motor configured to drive a compression mechanism and pumps the DEF to the DEF injector. A pressure sensor is configured to measure a pressure of the DEF output from the DEF pump. A sampling module is configured to, based on a rotational position of an output shaft of the electric motor, selectively output samples of the pressure. A measurement module is configured to determine a measured pressure at the pressure sensor based on a present one of the samples and a last one of the samples output before the present one of the samples. A pump control module is configured to apply power from a power source to the electric motor based on a difference between the measured pressure and a target pressure.

摘要： A thermally integrated catalyst aftertreatment exhaust system includes a flow channel that directs diesel exhaust through a diesel oxidation catalyst unit that includes a diesel oxidation catalyst, by a doser that introduces DEF into the diesel exhaust, through a mixing chamber that includes a static metallic mixer coated with a DEF hydrolysis catalyst, and through an SCR unit that includes an SCR catalyst. The diesel oxidation catalyst converts a portion of diesel exhaust into water, carbon dioxide, or nitrogen dioxide. The DEF hydrolysis catalyst facilitates hydrolysis of the mixed DEF and diesel exhaust. The SCR catalyst facilitates reduction of NOx in the diesel exhaust. A first portion of the flow channel is in direct thermal contact with a second portion of the flow channel that houses the SCR unit such that heat from the diesel exhaust before the diesel exhaust reaches the doser is passed to the SCR unit.

摘要： Methods and systems are provided for treatment of an exhaust stream, comprising nitrogen oxides. The method comprises a first oxidation of compounds comprising one or more of nitrogen, carbon and hydrogen in the exhaust stream; and a control of a first supply of a first additive to the exhaust stream to prevent an accumulation of soot exceeding a soot threshold value in a catalytic filter. This soot threshold value depends at least on operating conditions for the combustion engine, which impact a level of a flow for the exhaust stream. A first reduction of nitrogen oxides is performed using reduction characteristics of a catalytic coating in the catalytic filter and the supplied first additive. Soot particles are caught and oxidized. A control of a second supply of a second additive is performed, following which a second reduction of nitrogen oxides is performed using the first and/or the second additive in a reduction catalyst device.

摘要： The catalyst unit (1) for splitting a decontamination agent introduced into a containment for a decontamination process has at least one catalyst element (21). This catalyst element (21) first consists of a carrier material made of aluminum ceramics or activated carbon, and also of a catalytically active component in the form of nanoparticles, applied to the carrier material by means of chemical plating, and made of silver or silver oxide or of a silver and silver oxide mixture. The catalytically active component on the at least one catalyst element (21) is present in the range from 0.05 weight percent to 0.5 weight percent relative to the carrier material. The at least one catalyst element (21) has a catalytically effective surface in the range of up to 320 m2 per gram of used material, as a combination of carrier material plus applied catalytically active component. With the catalyst unit (1), an non-critical concentration of non-degraded decontamination agent of lower than 0.5 ppm, preferentially a maximum of 0.1 ppm can be achieved. The containment is configured in particular as an isolator, sluice or RABS (RestrictedAccess Barrier System), as well as being of a mobile and stationary type, such as means for transportation, and spaces for treatment, isolation and/or diagnosis of patients, as well as production spaces and laboratories.

摘要： Remote transactions using transactional memory are carried out over a data network between an initiator host and a remote target. The transaction comprises a plurality of input-output (IO) operations between an initiator network interface controller and a target network interface controller. The IO operations are controlled by the initiator network interface controller and the target network interface controller to cause the first process to perform accesses to the memory location atomically.
