ARRANGEMENT FOR THE POLLUTION CONTROL OF A MOTOR VEHICLE INTERNAL COMBUSTION ENGINE

摘要

The invention provides an arrangement for the pollution control of a motor vehicle internal combustion engine, of the type which comprises an exhaust line provided with an upstream device (10) for releasing a liquid component (CL) and a downstream device (12) for evaporating said component, these devices being intended to improve the efficiency of a downstream pollution-control member, characterized in that the downstream evaporation device (10) comprises at least one plate (24), of which at least one upstream part (28) is arranged in a diffusion region (30) of the component-releasing device (10) and of which a curved downstream part (32) is intended to bring about a swirling flow (T) of the mixture consisting of exhaust gas and vaporized component.
