Embodiment Construction

[0032] It should be noted that the drawings are given as examples and do not limit the invention. The drawings constitute schematic representations to aid in the understanding of the principles of the invention and are not necessarily to scale.

[0033] In particular, the shown sizes of the various elements do not represent actual sizes. The shape of the left or right rear fenders, fenders and access openings is especially non-limiting. exist Figure 4 In , the fender is not shown as a whole.

[0034] figure 1 and figure 2 has been described in the introductory part of this patent application.

[0035] In order to distinguish the present invention from the closest prior art, it will be compared figure 2 and image 3 .

[0036] as in image 3 As shown in , the invention consists in establishing directly on the fender 6 the shape of the drain groove 7a, which allows the overflow discharge of the liquid reductant overflowing in the groove 4a of the manhole 4, 4a to the...

Abstract

The invention relates to a rear wing (1) for a motor vehicle, said rear wing comprising a flap (4, 4a) for filling a tank with liquid reductant agent for a selective catalytic reduction system. The wing (1) also includes a mud guard (6) positioned at a distance from the wheel it is intended to cover. The flap (4, 4a) includes a housing (4) equipped with an overflow discharge port (5) for the liquid reductant agent, the overflow of liquid agent flowing from the discharge port (5) towards the mud guard (6). The rear wing is characterised in that the mud guard (6) comprises a longitudinal channel (7a) for directing the overflow liquid agent towards at least one longitudinal end of the mud guard (6). The invention is suitable for use in the field of motor vehicles.

Description

technical field [0001] The invention relates to a rear fender of a motor vehicle provided with a selective catalytic reduction liquid tank. Background technique [0002] Known levels of pollutants emitted by motor vehicles are subject to regulations. Among these pollutants, nitrogen oxides or NOx are more strictly regulated with increasingly stringent emission standards. [0003] To reduce NOx emission levels, NOx can be treated at the engine outlet by an aftertreatment system. Thus, the aftertreatment system of the exhaust gases of the engine comprises a selective catalytic reduction using a reducing agent, advantageously urea or other ammonia derivative, located upstream of the reducing catalyst. [0004] Such selective catalytic reduction systems are also known by the French abbreviation RCS and the English abbreviation SCR for "selective catalytic reduction". This decontamination device operates by injecting a liquid agent called liquid reductant, or RCS, into the exh...
