Transport Research Development Standard Organisation (RDSO), the research wing of Indian Railways in the process of developing a highly fuel efficient and Common Rail Electronic Direct Fuel Injection (CReDI) system.
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 percent are expected. Once the systems are implemented on the complete fleet of locomotives, savings will be about Rs. 500-600 crore annually.
In the long-term, complete manufacture, assembly and testing of the CReDI system shall be done in India placing India among the few countries possessing design and manufacturing capabilities for such sophisticated systems for large bore engines like locomotives, marine, trucks and battle tanks etc. Besides Railways many other Industries of India stand to gain from these developments.
Use of Common Rail systems has resulted in increasing the population of diesel passengers’ cars in Europe by more than 50%. European emissions laws are considered to be one of the most stringent across the globe.
