摘要： Methods and systems are provided for carrying out on-board diagnostics of a plurality of components of an exhaust heat exchange system. In one example, degradation of one or more of a heat exchanger and a coolant system fluidically coupled to the heat exchanger may be detected based on a first temperature estimated upstream of the heat exchanger, a second temperature sensor estimated downstream of the heat exchanger, a coolant temperature, and a pressure estimated upstream of the heat exchanger. Also, degradation of a diverter valve of the heat exchange system may be detected based on inputs of a position sensor coupled to the diverter valve.

摘要： Apparatuses and methods for reducing pollutants in a gas stream are disclosed. The gas stream is introduced into a condensation chamber to condense the gas stream. It then proceeds into a first reaction chamber adapted to electrochemically alter the gas stream. From there, the gas stream is directed into a reduction chamber adapted to reduce pollutants and a resonance chamber adapted to ionize the gas stream. The gas stream is then directed into a second reaction chamber adapted to further reduce pollutants in the stream. After treatment, the gas stream may be discharged into the atmosphere or recirculated through the apparatus to further reduce pollutants in the gas stream, the latter providing for a closed-looped system.

摘要： Pollutant removal from industrial exhaust gases such as combustion products generated by combustion of hydrocarbon fuels, such pollutant removal being characterized by refrigerating the products of combustion to remove most of the pollutants as a liquid phase. Pollutants thus removed include the water formed by the combustion process, together with those pollutants having a substantial solubility in the water in liquid phase. Precooling of the hot combustion products to about ambient temperature is highly desirable to reduce energy requirements in the refrigerating stage or stages. Single or plural stages of refrigeration and liquid phase separation are employed. Water soluble pollutants formed during the hydrocarbon fuel combustion process include formaldehyde and formic acid (which are also describable as water affinitive in the sense of forming azeotropic mixtures with the condensed water), and also hydrogen sulfide, sulfur dioxide, oxides of nitrogen, quinoline bases, and pyridine bases, for example. The pollutants removed by combining with the water condensed from the combustion products can be chemically or physically treated to neutralize and/or extract the pollutants from the water so that the resulting liquid can be discharged to the environment essentially pollutant-free. The water insoluble pollutants such as carbon monoxide which are not removed from the gaseous phase by refrigeration can be largely removed by passing the exhaust gases, after removal of the water and water soluble pollutants therefrom, through adsorber means or the like, such as a molecular sieve. By reason of the removal of the water and water soluble pollutants prior to passing of the gaseous phase through the adsorber means, the effective life of the adsorber means is increased by factor of at least 20 to 1.
摘要翻译：污染物从工业废气中排出，例如由碳氢化合物燃料燃烧产生的燃烧产物，这种污染物去除的特征在于将燃烧产物冷却以除去大部分污染物作为液相。这样去除的污染物包括由燃烧过程形成的水以及在液相中在水中具有很大溶解度的污染物。热燃烧产物预冷至约环境温度是非常需要的，以减少制冷阶段或阶段的能量需求。采用单级或多级制冷和液相分离。在烃燃料燃烧过程中形成的水溶性污染物包括甲醛和甲酸（在与冷凝水形成共沸混合物的意义上，它们也被描述为与水有亲和性），还有硫化氢，二氧化硫，氮氧化物，喹啉碱，和吡啶碱。通过与从燃烧产物冷凝的水结合而去除的污染物可以进行化学或物理处理，以中和和/或从水中提取污染物，使得所得液体可以基本上无污染物排放到环境中。通过制冷时未从气相中除去的一氧化碳等水不溶性污染物，可以通过吸附装置等除去水分和水溶性污染物之后，通过排出废气，大大地去除分子筛。由于在气相通过吸附器装置之前去除水和水溶性污染物，吸附器装置的有效寿命增加了至少20比1。

摘要： The invention concerns a method for unblocking pores in a metal zeolite based selective catalytic reduction (SCR) catalyst. The method includes filling, at least partially, the SCR catalyst with a liquid, the liquid being preferably distilled water. The method includes letting said liquid inside the SCR catalyst enough time to allow said liquid to dissolve, at least partially, the obstructions and to penetrate into the pores. The method includes heating the SCR catalyst at a temperature above the ebullition temperature of the liquid so as to vaporize the part of the liquid remained into the pores, and generate steam flows through the obstructions, the steam flows removing the obstructions and unblocking the pores, wherein no hydrocarbons are injected during the step of heating.

摘要： Provided are an exhaust pipe having turbulence wings, and an exhaust system. The exhaust pipe includes an outer pipe and an inner pipe. The exhaust pipe is connected to a scrubber of the exhaust system. The outer pipe has a gas inlet port. The inner pipe is installed in the outer pipe. A gap exists between the outer pipe and the inner pipe. The inner pipe includes a plurality of turbulence wings and gas discharge ports. The gas discharge ports are in communication with the gas inlet port via the gap. The turbulence wings project inward from the inner pipe and are disposed adjacent to the gas discharge ports. The inner pipe has an exhaust gas passage formed therein. When a gas is flowed through the gas discharge ports and over the turbulence wings, a jet layer is formed adjacent to an interior sidewall of the inner pipe. The jet layer forms a buffer between the exhaust gas passage and the inner pipe sidewalls. In this way, exhaust gases passing through the exhaust gas passage are prevented from contacting the inner pipe surface. Absorption of exhaust gas byproducts at the surface of the exhaust pipe is therefore reduced.

摘要： A silencer-separator having a cylindrical casing of circular cross section which is divided into an upper separator chamber and a lower expansion chamber. An inlet pipe directs a gas stream into the expansion chamber, and a pair of angularly disposed tubes direct the gas upward through a divider into the separator chamber with a swirling motion along the interior wall surface. A tubular central outlet extends through the upper end closure and has an entrance a substantial vertical distance therebelow. A peripheral baffle adjacent the interior wall collects entrained particles in the separator section and the collected particles are drained through a tube that may lead to the bottom of the expansion chamber. A perforated cylindrical body filled with a noise-attenuating fibrous substance is coaxially supported within the central outlet.
