Abstract

The invention discloses a post-treatment integrated device and a diesel engine. The post-treatment integrated device is used for treating exhaust gas of the diesel engine and comprises a diesel oxidation catalyst, a diesel particulate filter, a urea mixer, a selective catalytic reducer and an exhaust pipe, wherein the diesel oxidation catalyst, the diesel particulate filter, the urea mixer, the selective catalytic reducer and the exhaust pipe sequentially and detachably communicate in the flow direction of the exhaust gas; and the diesel oxidation catalyst, the diesel particulate filter and the selective catalytic reducer are respectively and detachably connected to a whole vehicle. According to the post-treatment integrated device and the diesel engine, the diesel oxidation catalyst, thediesel particulate filter, the urea mixer, the selective catalytic reducer and the exhaust pipe are directly detachably connected without a transition pipeline, so that the connection mode is simplerand easy for disassembly and assembly, the arrangement space of the whole vehicle is reduced, and the cost is effectively controlled; and in addition, each catalyst is detachably connected with the whole vehicle, the connection mode is favorable for transportation and assembly, and the matching of catalytic devices and the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of diesel engine aftertreatment, in particular to a diesel engine aftertreatment integrated device and a diesel engine. Background technique [0002] As the area and degree of smog in China continue to increase, the public is increasingly concerned about air pollution. The exhaust gas emission of diesel vehicles is one of the many factors of air pollution. According to the requirements of the National VI emission regulations for heavy-duty vehicles and the European experience in meeting the Euro VI regulations, the current mainstream technical route for diesel engine exhaust gas treatment is: DOC (Diesel Oxidation Catalyst) + DPF (Diesel Particulate Filter) + SCR (Selective Catalytic Reduction device). In the prior art, the above-mentioned catalytic converters with different functions are usually connected by pipelines, and then the pipelines are connected to the adjacent catalytic converters through flang...
