Abstract
An exhaust gas treatment system to be fitted on a chassis of an automotive vehicle. The system includes a selective catalytic reduction device and a gaseous fluid supplying device. The gaseous fluid supplying device includes a tank containing a material which is capable of retaining gaseous fluid by absorption and/or adsorption and/or formation of chemical complexes, and of releasing previously retained gaseous fluid. The gaseous fluid supplying device further includes a gaseous fluid delivery system capable of causing the release of gaseous fluid by the material and an injection system for injecting gaseous fluid upstream from the selective catalytic reduction device. Additionally the system may include a particulate filtering device. The particulate filtering device, the selective catalytic reduction device and the gaseous fluid supplying device are arranged within a same frame which includes fastening means for fastening the frame to the vehicle chassis.
