Abstract
La présente invention concerne un dispositif d'injection de carburant avec inhibition au démarrage. Des injecteurs de carburant 10 sont reliés à une canalisation d'arrivée 14 qui est maintenue à pression sensiblement constante pendant le fonctionnement du moteur. Les injecteurs sont excités par un générateur d'impulsions de largeurs variables 80. Ce générateur 80 est associé à un circuit d'inhibition 88 connecté à un capteur de pression 90 et à une thermistance 84. Application à la diminution de la pollution par des moteurs lors de démarrages à chaud.The present invention relates to a fuel injection device with start-up inhibition. Fuel injectors 10 are connected to an inlet line 14 which is maintained at substantially constant pressure during engine operation. The injectors are excited by a pulse generator of variable widths 80. This generator 80 is associated with an inhibition circuit 88 connected to a pressure sensor 90 and to a thermistor 84. Application to the reduction of pollution by engines during hot starts.
