Patent ID: 7604676

Claim:
An inertial impactor that uses emission gas stream flow rate to separate oil particles in internal combustion engine crankcase emissions, comprising: a housing having a top, a bottom and sidewalls extending substantially unbroken therebetween to define a hollow body having an interior with an interior surface and an exterior with an exterior surface; said top having an aperture to permit a flow nozzle to pass therethrough; said nozzle having a funnel at one end with a diameter that is larger than a diameter W of a throat portion that extends a predetermined distance T and stops a predetermined distance S from said bottom; said nozzle in fluid communication with said emission gas stream flow from said engine crankcase; said bottom in close proximity to an exhaust manifold to act as a heat source to facilitate deposition of said oil particulates on a primary impactor plate; said sidewalls further equipped with secondary impactor plates located at predetermined locations along said interior surface and extending into said interior space; one said sidewall further equipped with an orifice to permit emission gas stream flow from the engine crankcase through the housing, across the primary impactor plate, across the secondary impactor plates and out the orifice in the sidewall to a turbocharger.
