Technical Field
The invention relates to the technical field of automobile fuel supply systems, in particular to an extensible fuel supply and urea supply integrated module.
Background
The Selective Catalytic Reduction (SCR) technology is a treatment process for nitrogen oxides (NOx) in tail gas emission of diesel vehicles, namely, under the action of a catalyst, a reducing agent ammonia or urea is sprayed to reduce the NOx in the tail gas into N2 and H2O. The catalyst includes noble metal and non-noble metal. The technology is also widely applied to the post-treatment of the tail gas of the diesel engine, the generation of particulate matter PM is controlled as much as possible in the machine by optimizing the oil injection and combustion processes, and then the nitrogen oxide formed under the oxygen-rich condition is treated outside the machine, namely the urea is used for carrying out selective catalytic reduction on the nitrogen oxide (NOx) by using a vehicle, so that the aims of saving energy and reducing emission are fulfilled. The SCR technology is basically adopted in the truck exhaust treatment technology emitted by four or more countries, namely, harmful substances in exhaust of an engine are catalytically reduced by urea, so that a large-volume urea tank is required to be arranged on a vehicle body to store urea. While trucks typically employ diesel engines, diesel fuel also requires a large volume fuel tank for storage.
At present, integrated modules similar to those containing a urea box and a fuel box exist in the market, but all the integrated modules have the problem of poor expansibility. If the size of the accessory is changed greatly (particularly the size of the accessory is increased), the original groove cannot accommodate the accessory, and the development of a fuel tank blow mold is required again.
