Abstract:
1. A particle collector for use within an exhaust gas stream comprising: a housing having an internal chamber and having an inlet port and an outlet port in gas flow communication therewith; a collector element disposed within the internal chamber and comprising a particulate passage disposed axially therethrough wherein the particulate passage comprises a conical wall surface that decreases in diameter moving axially away from the housing inlet port; a gas passageway interposed between an outside diameter of the collector element and an inside diameter of the internal chamber wherein the outside diameter of the collector element and the inside diameter of the internal chamber increase and subsequently decrease, in a direction axially away from the housing inlet port toward the housing outlet port, to thereby configure the gas passageway as to have sufficient dimension to ensure a desired gas flow through the particle collector while producing a minimal pressure drop therethrough during operation of the particle collector; and a collection port that extends from the particulate passage to a location outside of the internal chamber for removing collected particulate matter from within the housing to a location outside of the housing.
