Winds Sweep Car From ITS Surabaya, the Winner of the economical fuel in the Shell Eco Marathon Asia 2010 Championship
According to one of the creators of wind 2 Witantyo broom, in fact the key to fuel economy not only in the engine, but how to make the vehicle as light and as small as possible friction. If a heavier vehicle fuel consumption would also more wasteful. He explained the first principle to conserve fuel is to reduce vehicle weight and friction. lighter engine means cultivated. Sweep the wind using a motorcycle engine honda 100 cc revolution that has been modified. Heat engines are usually issued on hold, the goal in order to push the piston down longer, so it is not immediately discarded heat. For fuel efficient engines is how to keep the heat is not much wasted away, and engine friction is also minimized and low rotation torque is increased, so the engine is powerful enough even though the engine turns low. To design a lightweight, all the accessories that attach to the car weighed in advance, the goal for vehicle weight of not more than 100 kg. Winds Sweep 2 is made of aluminum and lightweight body used for glass fiber materials. while for the aerodynamics to the speed of 25 km / h is not too dominant. At the time of the test driver Winds Sweep 2 students majoring in Engineering FTI ITS Alfie Hudan Nuzula alarming engine overheated because the heat is retained. The cost of making both types of these cars cost around $ 300 million, which contributed 30 million campus and the rest from sponsorship and help of alumni who are concerned with the development of technology in ITS
