Abstract:
An exhaust gas particle trap for an internal combustion engine comprising:a housing defining an inlet configured for fluid coupling to an exhaust manifold of the engine to receive exhaust gas produced thereby, and an exhaust gas outlet; an acceleration region fluidly coupled to said inlet of said housing and configured to increase exhaust gas flow velocity therethrough; and an elongate 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 fluidly coupled to said outlet of said housing, 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.
