The invention relates to a system for reducing fuel consumption in vehicles. According to the invention, fuel consumption is reduced by minimizing the aerodynamic resistances generated as the vehicle moves forward. The inventive system conveys air to the rear or stern of the vehicle where a depression is known to form. In a preferred embodiment of the invention, the air is conveyed using a tubular casing which is fixed to the rear part of the vehicle roof and which bends slightly towards the rear end. The air is channeled from the upper part of the forward-moving vehicle and is released at the low-pressure stern area, the depression serving as a suction device which facilitates the passage of the air. The outlet is oriented towards, but does not extend to the top of the rear doors.

The invention claimed is: 1. A system for reducing fuel consumption in a vehicle by minimizing the aerodynamic resistance caused by forward motion of the vehicle, the system comprising: a tubular structure configured to be placed on a rear part of a roof of the vehicle and extending around to a top part of a rear part or stern of the vehicle, said tubular structure being configured to provide air to the rear part or stern of the vehicle where a low pressure area is created as a result of the forward motion of the vehicle, said tubular structure including an outlet directed downward and an inlet with a smaller section than said outlet to prevent high pressure, and including a top wall, a bottom wall, and horizontal walls, said top and bottom walls being connected to reinforcement ribs, said reinforcement ribs being vertical plates welded to said horizontal walls and having holes or openings to balance the pressure in tunnels or chambers formed between said reinforcement ribs, wherein said tubular structure is configured to act as a funnel by taking air from a top part of the vehicle during forward motion and channeling and balancing the air from the top part of the vehicle to the low pressure area of the rear part or the stern of the vehicle. 2. A system for reducing fuel consumption in a vehicle according to claim 1, wherein said tubular structure is permanently fixed to the vehicle.
