ERODE: An academician-turned-entrepreneur in Erode has claimed to have made a device intended to improve fuel efficiency of petrol cars by about 15 per cent on normal road conditions.

S. Nehru, who worked as a faculty in a private polytechnic college, converted his idea into a product at the Technology Business Incubator at Kongu Engineering College here.


Mr. Nehru used embedded technology to develop the fuel saver for the petrol cars having the Multi Point Fuel Injection system.

“I came across this concept as the fuel prices are going up time and again, forcing people to spend more and more for transportation. I designed this fuel saving device to work with various models of all the car brands. We have fitted the device for testing in more than 25 cars manufactured by different companies and the results are very positive. The vehicle users are able to save about 15 per cent of the fuel consumption,” says Mr. Nehru. The device, Mr. Nehru says, does not tamper with the existing system in a car and it interfaces only with injectors. “The performance of the car will not affected. it only helps save fuel,” he says.

The TBI, which was a joint venture of the Department of Science and Technology, Government of India, and Kongu Engineering College, initially funded Rs. 5 lakh.

“After evaluating the progress of the project, an additional fund of Rs. 15 lakh was sanctioned,” its Executive Director S. Balamurugan says.


“We have run a number of tests such as dynamo metre test using advanced systems. We have also approached the Automotive Research Association of India for more tests and approval,” he said.

Mr. Nehru has plans to approach the car manufacturers to explore the possibilities of integrating the device during the manufacturing stage.
