Die Schalldämpfer-Anordnung umfasst außerdem eine Abgas-Bypass-Vorrichtung (2) mit mindestens einem stromaufwärts zu dem mindestens einen Auspuff-Endtopf (16, 17) angeordneten Anschluss-Stück (7, 8) zum Anschluss an eine Abgas-Krümmer-Vorrichtung (1) und mindestens einem Abgas-Bypass-Rohrkörper (13), der mit dem mindestens einen Anschluss-Stück (7, 8) in Strömungs-Verbindung steht und mindestens einen Abgas-Bypass-Auslass zum Auslassen des Abgases aus der Schalldämpfer-Anordnung aufweist.
Abstract:
An exhaust aftertreatment system for treating exhaust flow from an internal combustion engine, and associated method, allows for independent control of exhaust flow through plural exhaust legs of the exhaust aftertreatment system. The independent control of exhaust flow is carried out by adjusting a valve positioned in each the exhaust legs based on a value of a signal generated by a flow measurement device positioned along at least one of the exhaust legs. The valves can be adjusted to force a target flow in a exhaust leg, relative flow among exhaust legs, exhaust temperature in an exhaust leg, exhaust backpressure and/or imbalance within the exhaust legs.
Abstract:
The present invention relates to an Automotive Exhaust System, herein after referred to as Switchable High Performance Exhaust system, having exhaust header tubes (2) attached to the exhaust ports of a multi-cylinder engine at one end and terminating in to an expansion chamber (1) at the other end, which expansion chamber (1) is provided with two types of outlets (34). One type of outlet or outlets (3,4) is connected to the "legally Compliant Exhaust System". The other type of outlet or outlets (3, 4), called auxiliary outlet (3) or outlets (3), are openable and closeable at will, to enable the vehicle to be driven in "High Performance Mode" when the said auxiliary outlets are open. It also enables the vehicle to be driven in "Legally Compliant Mode" when the auxiliary outlets (3) are closed. Due to this system, the engine performs more efficiently, developing more power and/ or reducing the first consumption.
Abstract:
The invention relates to a fluidic switching element consisting of a feed channel (1), a Coanda tulip (5), at least two outlets (11, 12) and a displacement body (6) that is arranged in the area of the Coanda tulip (5) and is provided with an essentially even flow surface (7). A casing (8) is joined to said surface (7) in the direction of flow. The transitional area between the flow surface (7) and the casing (8) is defined by a separating edge (15).

본 발명은 배기가스의 탈질을 위한 SCR 탈질시스템에 관한 것으로, 보다 상세하게는 엔진으로부터 배출되는 배기가스의 질소산화물을 제거하는 탈질시스템에서 반응기 전단에서 배기가스의 폐열을 회수하는 열교환기에 의해 온도가 낮아진 배기가스가 탈질반응에 부적합한 온도가 되는 경우 온도보상 바이패스관을 통해 열교환기 전단의 온도가 높은 배기가스 일부를 열교환기를 통하지 않고 우회시켜 열교환기 후단의 배기관에 주입함으로써 혼합챔버 및 반응기에 유입되는 배기가스의 온도가 탈질반응에 적합한 온도를 유지할 수 있도록 하는 온도보상 구조를 갖는 탈질시스템 및 그 방법에 관한 것이다.
Abstract:
A thermoelectric power generating system is provided that includes at least one thermoelectric assembly. The at least one thermoelectric assembly includes at least one first heat exchanger in thermal communication with at least a first portion of a first working fluid. The first portion of the first working fluid flows through the at least one thermoelectric assembly. The at least one thermoelectric assembly includes a plurality of thermoelectric elements in thermal communication with the at least one first heat exchanger. The at least one thermoelectric assembly further includes at least one second heat exchanger in thermal communication with the plurality of thermoelectric elements and with a second working fluid flowing through the at least one thermoelectric assembly. The second working fluid is cooler than the first working fluid. The thermoelectric power generating system further includes at least one heat exchanger portion configured to have at least some of the first portion of the first working fluid flow through the at least one heat exchanger portion after having flowed through the at least one thermoelectric assembly. The at least one heat exchanger portion is configured to recover heat from the at least some of the first portion of the first working fluid.
Abstract:
A safety device for an exhaust gas after treatment system provides an alternative exhaust route in case of high temperatures or pressures within the regenerating particulate filter of the exhaust gas after treatment system that may cause damage to the particulate filter. The safety device comprises a valve that redirects the flow of exhaust gas from the regenerating particulate filter when specified temperature or pressure thresholds are met or exceeded.
