摘要： Catalyst for an internal combustion engine exhaust line, characterized in that it is formed by the stack, in this order, of: an active phase (3) based on precious metals, which forms an electrode; an electrolyte (1) having an ionic conductivity, through O2- ions, of 0.01 mS/cm or higher at 200°C; and a back electrode (4), and in that the catalytic properties of said active phase (3) can be activated at 100°C through the effect of electric power of 0.1 µW/cm2 of active phase (3). Device for reducing polluting emissions including this catalyst and use of this device for the conversion of hydrocarbons, CO and NOx.

摘要： The invention relates to a device for treating the exhaust gases from a heat engine, said device comprising a particle filter that is formed of a porous material for trapping and oxidizing the soot and a catalyst for selectively reducing the nitrogen oxides deposited on the outlet surfaces of the walls of the particle filter. The invention involves selecting said selective reduction catalyst from among those having a specific surface area of at least 65 m

摘要： The invention relates to a system for treating nitrogen oxides by selective catalytic reduction (SCR), intended to be installed in the engine exhaust system (10) of a vehicle. According to the invention, the nitrogen oxides are chemically reduced in an SCR catalytic converter (12) while injecting ammonia in the form of liquid urea (14), pure or in solution, said liquid urea (14) being stored in a special tank (16) intended to be installed in the vehicle. The system includes a return pipe (11) connecting an outlet of the tank (16) to the exhaust system (10) of the engine such as to direct the ammonia vapour emitted during the breakdown of the urea in the tank (16) towards the engine exhaust system (10) upstream of the SCR catalytic converter (12).
