In order to alleviate the effect of rising fuel prices and increasing pollution from transport sector, Research Development Standard Organisation, the research wing of Indian Railways is in the process of developing a highly fuel efficient, Common Rail Electronic Direct Fuel Injection system for its fleet of diesel locomotives.
On diesel locomotives, however, this technology is beginning to be implemented world over recently. Indian Railways has taken a global lead in starting development of the CReDI for its fleet of diesel locomotives. For this purpose, an Indian manufacturer has established a joint venture with a reputed firm from Switzerland for design and development of the system under overall supervision of RDSO.
Final testing of the system will be done at the large bore engine laboratory of RDSO. Fuel savings in the range of 3 to 4 per cent and emissions reductions by about 20-30% are expected. Once the systems are implemented on the complete fleet of locomotives, savings will be about INR 500 crore to INR 600 crore annually.
