How they work...

This innovation uses aerospace technology to reduce the fuel consumption of motor vehicles. This is achieved by the use of specifically designed vortex generators (VG FUELSAVERS) which have been developed for the speed ranges of modern motor vehicles. These VG FUELSAVERS are attached to the rear of motor vehicles as in shown here:

Sedan	Hatchback

The VG FUELSAVERS are constructed from folded aircraft aluminium for maximum strength and durability with cost and manufacturing issues taken into consideration. They may be painted with good quality paints, this will not degrade performance of the VG FUELSAVERS.  The VG FUELSAVERS create strong vortices of air which cause the boundary layer airflow, which was previously detached and turbulent, to become reattached and laminar. This turbulent air at the rear of the motor vehicles is known as 'drag'. The VG FUELSAVERS, in creating laminar flow of the air around the rear of the vehicle reduce this total 'drag', this then reduces fuel consumption due to the engine not having to work as hard to produce the same vehicle speed.

The diagram below depicts the flow with and without VG FUELSAVERS:

The VG FUELSAVERS are affixed to the vehicles using high quality double- sided adhesive tape or  industrial silicone adhesive.  VG FUELSAVERS are precision designed vortex generators specifically tailored to the speeds of today's motor vehicles.  These units produce strong vorticies (small tornadoes) which cause the boundary layer of the airflow to stick to the back of the vehicle, this gets rid of the drag inducing 'eddys' of air and introduces smooth laminar airflow. The same applies for station wagons ,hatches , 4wds ,and other vertical backed vehicles although the airflow does not stick to the back of the vehicle it 'fills in' the low pressure area behind the vehicle reducing the drag.

This reduction in the total drag of the vehicle shows its benefit by reduced fuel consumption due to the engine not having to work as hard for the same vehicle speed as the total load is less. This technology is extensively used by major aircraft manufacturers (Boeing,Airbus,Learjet) to improve the performance of their aircraft.
