REDUCER INJECTION DEVICE FOR SELECTIVE CATALYTIC REDUCTION

摘要

The invention relates to a reducer injection device (20) for selective catalytic reduction in a combustion-gas exhaust line, the device including a channel (60) for supplying reducer and a tip (80) for injecting reducer into the exhaust line, the injection device also including a pump (30) for circulating the reducer in a first direction towards the injection tip (80) and for circulating the reducer in a second direction towards the supply channel (60). The invention also relates to an exhaust line and to a vehicle including the reducer injection device (20). The invention thus makes it easier to integrate a selective catalytic reduction system in a vehicle.
