Description
Technical Field
The utility model relates to the technical field of automobiles, concretely relates to thermal-insulated heat preservation cover of diesel oil aftertreatment device.
Background
With the implementation of the emission of the fifth and sixth countries, the technical scheme of DOC + DPF after-treatment is adopted by manufacturers of light diesel vehicles to meet the emission requirements of the regulations. Among them, the DOC (Diesel oxidation catalyst) Diesel oxidation catalyst uses a catalyst containing precious metal to further oxidize HC, CO, NO and volatile substances on the surface of particles in the engine exhaust, thereby reducing harmful exhaust gases such as HC, CO, NO, etc. DPF (Diesel Particulate Filter) Particulate trap, which is a Filter installed in an exhaust system of a Diesel engine, is mainly used for trapping Particulate matter in exhaust gas, that is: the PM is detected by a differential pressure sensor, and when the value of the PM meets a regeneration request, an ECM (engine control module) starts a regeneration mode to purify the PM collected by the DPF. Because both DOC (oxidation-reduction) exhaust purification and DPF regeneration (particulate matter purification) need to be performed in a high-temperature environment, the existing products of DPF and DOC do not have a heat insulation device. Peripheral parts such as pipelines and wire harnesses are easily subjected to heat radiation, so that the use and aging of the parts are accelerated, and the heat preservation of DOC oxidation reduction and DPF regeneration temperature is not facilitated. To maintain a constant high temperature, more fuel consumption is wasted, resulting in poor fuel economy.
