On track, a locomotive designed to burn less oil
A diesel locomotive equipped for the first time in India with an electronic fuel injection system, an innovation developed by the Railways’ Lucknow-based Research Designs and Standards Organisation in collaboration with IIT-Kanpur, is expected to save between Rs 200 and Rs 450 crore annually in the fuel expenditure of Indian Railways.
After trials on RDSO’s research test beds in June and July, the locomotive was flagged off on a field trial in September. It is hauling a passenger train between Sultanpur and Lucknow and the results have been encouraging. After March 2012, when the trial is complete, EFI-fitted locomotives will go into production.
“With the electronic fuel injection system, we have stepped up from technology of mechanical fuel injection by a generation, and it is an important chapter in the history of locomotive technology development in India,” said Dr Avinash Kumar Agarwal, associate professor of mechanical engineering at IIT-Kanpur.
The diesel engine of a locomotive operates at nine notches for different speed levels, from the idle notch to the eighth that involves the highest speed. In the mechanical fuel injection system that is currently used, the fuel supply to the engine at each notch is provided at a predetermined quantity at a predetermined time, with no way of determining whether the conditions at that time are ideal for such an injection.
It is only at the eighth notch, Agarwal said, that fuel consumption in this system can be optimised. But at this notch, the train runs for approximately only ten per cent of the time. Hence the mechanical fuel injection system has only a limited effect on the overall fuel efficiency of the locomotive.

Good to see all those Photoshop images taking real shape...I was in Mumbai last year for a conference in Grand Maratha Sheraton Hotel near International Airport, it's one of the best hotel I have ever seen, it's with royal opulence but built recently!!! - Mumbai is a great city with lots of beautiful places....
