An investigation of vehicle wind turbine system

Wine turbine applications such as battery charging for auxiliary power for boats or to power traffic warning signs. Wind turbines are becoming an increasingly important source. A wind turbine is a device that converts kinetic energy from the wind into electrical power. The Generator supplies the electricity by connecting to the pulley system of engine of vehicle generally. In order to investigate energy-saving efficiency, a wind turbine of 400w was mounted to the front bumper of vehicle. In the experiment, there are two choices of charge types for vehicle. An electromagnetic clutch was designed for cutting charge system by wind turbine with a button in the car. Fuel consumption can be reduced using wind turbine. Generator is driven by engine pulley system when vehicle starts, it will be occupied about 30% fuel consumption by this type generally. The generator can be switched driven by wind turbine while the vehicle moves at a stable speed on road, fuel consumption can be reduced about 15% by the wind turbine. The charge type can be set to wind turbine system when car speed is higher than 50kilometers, and the higher, the more efficiency. While wine turbine system will self-stop when wind speed is too high at car speed more than 120 kilometers for safety. The road experiment results revealed that proposed vehicle wind turbine system saved about 15% fuel consumption when car speed is higher than 80 kilometers.
