Patent ID: 7833301

Claim:
An air pre-cleaner aspirator system for an air breathing fuel consuming internal combustion engine having an air intake and an exhaust for the products of combustion at elevated temperatures, said engine having a pre-cleaner fluidly connected to and upstream of the engine air intake, said pre-cleaner preventing flow of larger contaminants into the engine air intake and accumulating such contaminants, said pre-cleaner having an outlet for such contaminants, said system comprising: an element defining a primary flow path for engine exhaust, said element having a venturi section; a tube having an outlet within said element adjacent said venturi section, said tube being fluidly connected to the pre-cleaner outlet for contaminants so that contaminants are drawn into and through said tube; and said element having at least one inlet for ambient air into the primary flow path for cooling the engine exhaust stream adjacent said element.
