Abstract
A motor vehicle ventilation system configured to ventilate a cabin of the vehicle. The ventilation system comprises a duct extending about a perimeter of the vehicle cabin, at least one air flow inducer configured to induce a flow of air through the duct, the duct comprising an air inlet to receive a bulk flow of air from the flow inducer, and a first opening that extends about the perimeter of the vehicle cabin and that receives air from the duct. The first opening is configured to expel air into the vehicle cabin. The ventilation system further comprises a second opening that extends about the perimeter of the vehicle cabin and that draws air in from the vehicle cabin into a passage extending about the perimeter of the vehicle cabin, wherein a flow through the first opening entrains a flow from the second opening.
