    • A combined EGR cooler and non-thermal plasma device has first and second fluid passageways which are in heat exchange communication with one another. One or more electrodes are located in the second fluid passageway. The electrodes are connected to a voltage source. When a voltage of sufficient magnitude is applied to the electrodes, a non-thermal plasma is generated in the second fluid passageway. The device can be constructed in the form of a shell-and-tube heat exchanger or a stacked-tube type heat exchanger, wherein the electrodes extend through the heat exchange tubes. Hot exhaust gases preferably flow through the tubes in heat exchange contact with a liquid coolant, thereby cooling the exhaust gases. The electrodes generate non-thermal plasma inside the tubes, converting at least a portion of the NO in the exhaust to NO2, which reacts with soot in the exhaust gases to generate CO2 and N2, thereby cleaning the exhaust gases.
    • 组合的EGR冷却器和非热等离子体装置具有彼此热交换连通的第一和第二流体通道。 一个或多个电极位于第二流体通道中。 电极连接到电压源。 当对电极施加足够大的电压时,在第二流体通道中产生非热等离子体。 该装置可以以壳管式热交换器或层叠式热交换器的形式构成,其中电极延伸穿过热交换管。 热废气优选通过与液体冷却剂热交换接触的管流动,从而冷却废气。 电极在管内产生非热等离子体,将废气中的NO的至少一部分转化为NO 2,其与废气中的烟灰反应,以产生CO 2, SUB>和N 2,从而清洁废气。
