Abstract

Liquid and/or particle-shaped impurities are precipitated from a stream of gas, for example, from a stream of gas that originates from a crankcase of an internal combustion engine and is directed to the engine's intake side. The stream of gas is passed through a gas discharge section between two electrodes. The stream of gas is passed between an emission electrode which is formed by electrode tips and an opposing electrode at a distance therefrom. A direct voltage which exceeds the breakdown voltage is applied to the electrodes using a direct current high voltage source, and the current which occurs over the gas discharge section between the electrodes is limited. A stable low energy direct current plasma is formed in the space between the two electrodes. The impurities are electrically charged and attracted to the opposing electrode by means of electrical field forces.
