A motor vehicle comprising a motor - fan reversible and means for detection of a critical situation.

摘要

The present invention relates to a motor vehicle comprising a passenger compartment (5), an engine compartment (4) adjacent to the passenger compartment (5), a motor housed in the engine compartment (4), an aeration conduit (15) which connects the passenger compartment (5) to the outside of the vehicle by passing through the engine compartment (4), and a motor - fan (10) with fins (13) for the intake of outside air through the aeration conduit (15) toward the passenger compartment (5). According to the invention, the motor / - fan (10) are overlapped is reversible and the vehicle comprises means for detecting a critical situation (14), arranged in the engine compartment (4), which are connected to the motor / - fan (10) in order to reverse the direction of rotation of the motor / - fan (10) when a critical situation is detected, by means of which the air located in the passenger compartment (5) is forced towards the outside of the vehicle through the aeration conduit (15).
