Engine exhaust gas recirculation particle trap

An exhaust gas particle trap for an internal combustion engine comprising:

• a housing having a first conduit having a first end defining an inlet configured for receiving exhaust gas produced by the engine and a second opposite end defining an outlet, and a second conduit having a first end defining an exhaust gas outlet of the particle trap and a second opposite end;
• a flow deflector adjacent to said second end of said first conduit and operable to deflect exhaust gas flowing through said first conduit;
• and
• an elongate chamber defining at one end an inlet receiving exhaust gas deflected by said flow deflector, at an opposite end a debris receiving portion, and an exhaust gas portal therebetween fluidly coupling said chamber to said second end of said second conduit, said portal positioned relative to said chamber inlet such that exhaust gas entering said chamber inlet is projected beyond said portal into said debris receiving portion where particles carried by the exhaust gas are collected before the exhaust gas exits said portal.

An exhaust gas particle trap for an internal combustion engine comprising:

• a housing having a first conduit having a first end defining an inlet configured for receiving exhaust gas produced by the engine and a second opposite end defining an outlet, said first conduit extending along a first axial reference, and a second conduit having a first end defining an exhaust gas outlet of the particle trap and a second opposite end, said second conduit extending along a second axial reference;
• a flow deflector adjacent to said second end of said first conduit and operable to deflect exhaust gas flowing through said first conduit;
• an acceleration region fluidly coupled to said flow deflector and configured to increase exhaust gas flow velocity therethrough;
• and
• an elongate chamber extending along a third axial reference, with said first, second and third axial references substantially parallel and offset relative to each other, said chamber defining at one end an inlet receiving exhaust gas from said acceleration region, at an opposite end a debris receiving portion, and an exhaust gas portal therebetween extending transversely between said chamber and said second end of said second conduit, said portal positioned relative to the chamber inlet such that exhaust gas exiting said acceleration region is projected beyond said portal into said debris receiving portion where particles carried by the exhaust gas are collected before the exhaust gas exits said portal.
