This invention is about an air intake system which is used to discharge the air of environment inside the vehicles such as bus, minibus, and etc. The air intake system (Figure 2) subject to this invention is consisting of an air duct placed parallel to the drive direction of the vehicle and an air intake duct which is starting from the top of this air duct and opening to the trunk of the vehicle, and at the junction point of these two ducts, it is possible to get a low pressure area by means of air current obtained from the running speed of the vehicle. By the effect of this low pressure area which is created incidentally and by taking the advantage of pressure differences in between these two environments, the air inside the vehicle can be discharged by means of the air intake duct without the need for any source of energy. |
