Abstract: An exhaust system that includes a catalytic converter, selective catalytic reduction system, a muffler and, for certain applications, a diesel particulate filter that each include at least one filter that has an electric heating element, a metallic coating and a plurality of metal rods extending therethrough. The combination of elements are configured to heat the internal housings of the exhaust system and disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants.

Abstract: Coated gasoline particulate filters (cGPFs) that are produced according to varied material compositions and catalyst configurations are disclosed. The cGPFs include Fe-Ce (rich)-activated Rh compositions that provide greater catalytic functionality. These cGPFs are incorporated within engine systems as components of TWC systems for controlling and reducing engine exhaust emissions. The conversion performance of these TWC systems is assessed and compared employing worldwide harmonized light duty test cycle (WLTC) protocol within a gasoline fueled internal combustion engine. These TWC systems exhibit a significant catalytic performance when compared with the catalytic performance of a PGM-based Original Equipment Manufacturer (OEM) catalyst employed in TWC applications. Further, TWC catalysts are produced including Fe-activated Rh layers comprising dopant elements. The catalytic performance of the TWC catalysts is evaluated by performing light-off and standard isothermal oxygen storage capacity oscillating tests. The TWC catalysts exhibit improved catalytic performance and significant oxygen storage capacity.

Abstract: The invention aims at provision of an engine device structured such that an attachment position of a support base (87) can be simply determined by coupling an exhaust gas outlet surface (7a) of an engine (1) and the support base (87), and it is possible to improve an assembly workability of the support base (87). The engine device of the present invention is provided with a first case (28) which removes particulate matters in exhaust gas of an engine (1), and a second case (29) which removes nitrogen oxides in the exhaust gas of the engine (1). The second case (29) is connected to the first case (28) via a urea mixing pipe (39). An exhaust gas inlet surface (34a) of the first case (28) is joined to an exhaust gas outlet surface (7a) of the engine (1), and a support base (87) firmly fixed to the engine (1) is provided. The support base (87) is partly brought into surface contact with the exhaust gas outlet surface (7a) of the engine (1).

Abstract: An exhaust gas control system for an internal combustion engine (1) includes: a first catalyst (4a) disposed on an exhaust passage for the internal combustion engine (1), the first catalyst (4a) being a NOx storage reduction catalyst; a second catalyst (6) disposed on the exhaust passage at a position downstream of the first catalyst (4a), the second catalyst (6) being a NOx selective catalytic reduction catalyst; a first NOx sensor (N2) mounted on the exhaust passage at a position between the first catalyst (4a) and the second catalyst (6); a second NOx sensor (N3) mounted on the exhaust passage at a position downstream of the second catalyst (6); and an electronic control unit (10). The electronic control unit (10) is configured to evaluate NOx reducing performance of the second catalyst (6) based on a value detected by the first NOx sensor (N2) and a value detected by the second NOx sensor (N3), when an evaluation condition is satisfied.
