With growing fuel costs and problems of global warming that are being faced by our planet, automotive industry is trying its best to create cars and engines that are more fuel efficient. In a recent news release Chevrolet unveiled the working of The Air Shutter system which is going to be used in the much awaited Chevrolet Cruze Eco model giving it a decently good fuel economy of 40MPG or 17 kmpl.
Air Shutter System Working
Greg Fadler, aerodynamics engineering group manager at Chevrolet and his team developed The Air Shutter system to make 2011 Chevrolet Cruze Eco one of the most fuel efficient small cars on the market achieving almost hybrid like fuel economy without the Hybrid cost and maintenance.
This was achieved by using commonly used techniques of reducing overall weight and ride height to provide it the aerodynamic benefit.
The real innovation is the front grill which has an automatic shutter system that senses wind flow and temperature conditions with sensors which, are connected to small electric motors that open and close the shutter as and when needed. When the car is moving at slow speed (city driving) the shutters open to provide maximum air flow to the engine for cooling thus, reducing radiator power consumption. The shutter remain closed during high speeds (highway driving), providing an increase in half a mile per gallon in combined city and highway driving.
The system however doesn't compromise with engine cooling in anyway. The system in fact helps to provide maximum cooing in the worst of conditions with the advantage of increased fuel economy.
