Abstract

Ce dispositif d'injection d'un additif liquide, comprend un réservoir d'additif (3) relié par un conduit d'additif (4) à un injecteur (5) placé dans le système d'échappement du véhicule concerné. Il est prévu, sur le conduit d'additif (4), une pompe volumétrique (6) aspirante et refoulante, comprenant un cylindre (7) et un piston (8) qui délimite dans le cylindre une chambre de mise en pression (11). Un actionneur électrique (9) est accouplé au piston (8) pour provoquer un recul avec aspiration de l'additif dans la chambre (11) depuis le réservoir (3) et une compression simultanée d'un ressort (10) agissant sur le piston. Grâce au ressort (10), l'avance du piston (8) avec refoulement de l'additif vers l'injecteur s'effectue sous pression contrôlée. Application à l'injection d'un mélange d'eau et d'urée, dans le cas de véhicules avec moteur utilisant le gasoil comme carburant.This device for injecting a liquid additive comprises an additive reservoir (3) connected by an additive duct (4) to an injector (5) placed in the exhaust system of the vehicle concerned. There is provided, on the additive duct (4), a positive displacement pump (6) for suction and pressure, comprising a cylinder (7) and a piston (8) which defines a pressurizing chamber (11) in the cylinder. . An electric actuator (9) is coupled to the piston (8) to cause a recoil with suction of the additive in the chamber (11) from the reservoir (3) and a simultaneous compression of a spring (10) acting on the piston. . Thanks to the spring (10), the advance of the piston (8) with delivery of the additive towards the injector is carried out under controlled pressure. Application to the injection of a mixture of water and urea, in the case of vehicles with an engine using diesel as fuel.
