Diesel engines to turn fuel-efficient

LUCKNOW: The first diesel locomotive equipped with Electronic Fuel Injection was flagged off at diesel locomotive shed by V Ramachandran, director general, RDSO, on Wednesday. It is the first-ever retro fitment of the EFI system on an ALCO locomotive in the world. It also ranks among very few EFI applications on large diesel engines. The engine will not only optimize fuel consumption in Indian Railways but also cut down emissions. In the first phase, railway board would be upgrading at least 100 diesel engines with the EFI system "within a year".
RDSO officers explained that unlike the widely used mechanical injection system, the EFI enables injection of fuel in precise quantity and at appropriate time so as to match the demand of load, optimize fuel consumption and cut down emissions. It monitors the need of fuel on a real-time basis. Besides, EFI loco could lead to savings of more than 2% over the duty cycle of the diesel locomotive. Railways consumes some 2.5 billion litre fuel every year and spends approximately Rs 10,000 crore on it. The EFI loco may help save Rs 200 crore.
The EFI system will also do away with the black smoke. "This will not only protect environment, but also save fuel since black smoke is caused by unburnt fuel," said the DG. It will also prevent the engine from running hot and ensure faster response to driver's action and fault diagnostics.
The engine, with an estimated cost of Rs 24-Rs25 lakh, will have a longer shelf-life of over 36 years. But it will be easier to maintain as large number of its mechanical components have been removed and made into an electronic operation.
The EFI system is a collaborative effort of Research Designs and Standards Organization, IIT-Kanpur and DMW, Patiala. Indian Railways had undertaken projects for modernization of over 4,000 diesel locomotives and the EFI is a major step in the direction.
The DG, RDSO shared that a committee has been constituted by railway board to look into SIMRAN project. Rs 110 crore has been sanctioned for the project, he added.
