Patent ID: 8202484

Claim:
A system for purifying exhaust gases of an engine, comprising: a housing with an inlet and an outlet, the inlet in communication with at least one engine cylinder, the outlet in communication with an atmosphere; a first catalytic converter element and a first filter element arranged in the housing such that a first portion of exhaust gases that flow from the at least one engine cylinder flow to the inlet and flow through the first catalytic converter element, and a second portion of exhaust gases flow from the at least one engine cylinder flow to the inlet and flow through the first filter element; and a second catalytic converter element and a second filter element, the second catalytic converter element positioned so that exhaust gases flowing through the first filter element flow through the second catalytic converter element, the second filter element positioned so that exhaust gases flowing through the first catalytic converter element flow through the second filter element, wherein the first catalytic converter element is connected in series with the second filter element, and the first filter element is connected in series with the second catalytic converter element, such that two separate and segregated flow paths are created in the housing, and wherein the first catalytic converter element and second catalytic converter element are SCR type catalytic converters and wherein the first filter element and second filter element are designed as diesel particle filters.
