摘要： A method and a device for selectively purifying the exhaust gas of an internal combustion engine using a selective catalytic reduction (SCR) catalytic converter (2), wherein a reducing agent is metered to the exhaust gas prior to entry into the SCR catalytic converter (2). An overdose of the reducing agent is added to the exhaust gas, and the exhaust gas, after exiting the SCR catalytic converter, is fed in part through an oxidation catalytic converter (5) and in part to a second SCR catalytic converter (8) via a bypass (6) circumventing the oxidation catalytic converter. In the oxidation catalytic converter (5), one half of the excess NH3 flowing out of the first SCR catalytic converter (2) is converted to NOx and reacts to form non-hazardous nitrogen after mixing with the other half of the excess NH3 flowing unchanged through a bypass.

摘要： Reverse flow heat exchangers including one or more pairs of contiguous ducts are provided. An intake duct conveys particle laden air, such as engine exhaust, to a combustion chamber and an exit duct conveys the purified air away from the combustion chamber. The exit duct is shaped such that the cross sectional area thereof varies as function of the length thereof, for example, the cross sectional area can increase as a function of distance from the combustion chamber. The intake duct can also be shaped to have a varying cross sectional area. A combustion purifier is formed by the combination of the combustion chamber with the reverse flow heat exchanger. When used in combination with an engine, the shapes of the ducts can serve to increase the power or efficiency of the engine by further reducing backpressure, as compared to a reverse flow heat exchanger without the shaped ducts.

摘要： A sealing device for a prismatic body that includes an elastic tube disposed on an inner circumference of a frame body, in which a prismatic body W, which is an object of sealing, is inserted. The elastic tube has a shorter inner circumferential length than an outer circumferential length of the prismatic body W. The frame body is formed with an air vent that connects to a backside of the elastic tube, with a vacuum source being connected to this air vent so that the elastic tube is expandable to increase its inner diameter by being sucked toward the frame body. Release of the vacuum from the elastic tube after insertion provides an instantaneous seal.

摘要： An exhaust system includes a combustion chamber and a radiation source configured to heat particles in an exhaust stream as the stream passes through the chamber. Once the particles are brought to an ignition temperature and begin to burn, the reaction within the chamber can become self-sustaining. The radiation source can comprise a resistive heating element, an infrared emitter, or a microwave emitter. The radiation source may radiate into the chamber through a radiation transparent window. The chamber may have a cross-section perpendicular to a longitudinal axis that is parabolic or partially parabolic. The exhaust system can also comprise a heat exchanger to pre-heat the exhaust before entering the chamber. Embodiments of the system can be configured to additionally perform as a catalytic converter and/or a muffler. A fuel such as urea or ammonia may be used in the heat exchanger for converting oxides of nitrogen. The exhaust system may be disposed between an engine and a turbocharger.
