Electrically operated separator for oil particles in a gas stream in an internal combustion engine's crankcase has emission and passive electrodes

摘要

Surrounded by an electrically insulating tubular sleeve (5), an emission electrode (1) fits inside a ring-shaped passive electrode (2). During operation, current flows through the electrode structure from top to bottom so that gas containing oil particles hits a needle-like corona area (3) in the emission electrode that links to a separator area (4) with a greater diameter.
