Abstract
A system for injecting an aqueous solution into an injection engine, includes: a tank for an aqueous solution, a circuit for supplying aqueous solution to the tank and a filter for filtering the aqueous solution, and a circuit for recirculating the aqueous solution. The injection system also includes recirculation of the aqueous solution, and is provided with an electrovalve including a first inlet connected to a filler neck of the tank, a second inlet connected to the recirculation circuit, and an outlet connected to the supply circuit. The filtration filter is arranged in the supply circuit and/or in the recirculation circuit.
