There is disclosed a device for separating oversize fuel particles in an air fuel mixture in internal combustion engines and recirculating them to the fuel supply system for reinjection and atomization by the carburetor or fuel injector. An array of low loss venturi nozzles with central traps is utilized to inertially separate the oversize particles, resulting in a fine, more uniform fuel size distribution to the engine inlet.

Apparatus for reducing the average fuel particle size in an air-fuel mixture for spark-ignition engines comprising inertial means for separating a portion of the air-fuel mixture containing fuel particles greater than a pre-determined size prior to its introduction to the cylinders of the engine, and means for returning the separated portion to the fuel supply system of the engine, said separated portion being re-circulated to the venturi portion of the engine from an area of higher staic pressure, wherin said inertial means comprises a particle separator having an array of elements, each element having a venturi-shaped housing and a centrally aligned trap disposed downstream of the throat into which the flow of fuel particles greater than a pre-determined size is inertially separated.
