Abstract: A burner for an exhaust gas treatment system includes a tubular inner housing having a closed upstream end, a reduced diameter portion, and a plurality of apertures downstream of the reduced diameter portion. An outer housing surrounds the inner housing comprising a bypass flow path therebetween. First and second tubular supports fix the upstream end of the inner housing to the outer housing and provide fluid communication between a cavity within the inner housing to a location outside of the outer housing. A plate fixes the downstream end of the inner housing to the outer housing and cooperates with the housings to partially define an aperture formed in a portion of the bypass flow path.
Abstract translation: 一种用于废气处理系统的燃烧器包括管状内壳体，其具有封闭的上游端，减小的直径部分和在直径减小部分下游的多个孔。 围绕内壳体的外壳体包括其间的旁路流路。 第一和第二管状支撑件将内壳体的上游端固定到外壳体并且在内壳体内的空腔之间提供流体连通到外壳体外部的位置。 板将内壳体的下游端固定到外壳体并与壳体协作以部分地限定形成在旁路流动路径的一部分中的孔。

Abstract: An exhaust aftertreatment system may include a first housing and a burner. The first housing may include first and second chambers. The first chamber may include an exhaust gas inlet receiving exhaust gas from an engine. The second chamber may receive exhaust gas from the first chamber and may include an exhaust gas outlet. The burner may include a second housing and a combustion chamber disposed within the second housing. The second housing may be at least partially disposed within the first chamber. The burner may supply heated gas to the second chamber. The heated gas within the burner may be fluidly isolated from exhaust gas in the first chamber. The second housing may be in a heat transfer relationship with exhaust gas in the first chamber.
Abstract translation: 排气后处理系统可以包括第一壳体和燃烧器。 第一壳体可以包括第一和第二腔室。 第一室可以包括从发动机接收废气的排气入口。 第二腔室可以从第一腔室接收废气，并且可以包括废气出口。 燃烧器可以包括设置在第二壳体内的第二壳体和燃烧室。 第二壳体可以至少部分地设置在第一腔室内。 燃烧器可以将加热的气体供应到第二室。 燃烧器内的加热气体可以与第一腔室中的废气流体隔离。 第二壳体可以与第一腔室中的排气处于热传递关系。

Abstract: An exhaust control system for a vehicle includes at least one temperature sensor, positioned within an exhaust system of the vehicle, that is configured to generate a measurement signal indicative of at least one of an inlet temperature and an outlet temperature of a diesel oxidation catalyst (DOC). An exhaust control module is configured to turn on an exhaust burner on to heat exhaust flowing through the exhaust system, determine a total stored heat within the DOC based in part on the measurement signal, subsequent to turning on the exhaust burner, turn off the exhaust burner based on an upper threshold of the total stored heat, and, subsequent to turning off the exhaust burner, turn on the exhaust burner based on a lower threshold of the total stored heat, wherein the lower threshold is less than the upper threshold.
