Apparatus and methods for separating particles from a fluid stream using an inertial effect.

摘要

To reduce the average size of fuel particles in the air-fuel mixture supplied to an internal combustion engine, particle separating means (11) are provided in the path of the air fuel mixture for removing oversize fuel particles which are then returned either to the carburetor or to the fuel supply system. The particle separating means (11) may comprise an array of elements each comprising a venturi-shaped housing (22) with a trap (24) alined with, but disposed downstream of, the throat (23) of the tube, or an array of vortex tubes (41).
