| Abstract | Real-Time Oil Consumption (RTOC-III™) measurements were made on a 1,500 kW EMD 16-645E locomotive diesel engine, as part of a program to evaluate commercially available cylinder kits that hold the potential to reduce lubricating oil consumption and hence reduce exhaust particulate matter emissions. The RTOC technique uses sulfur dioxide (SO2), as measured in the exhaust gas stream, as a tracer for oil consumption. The engine was operated on an ultra-low sulfur diesel fuel and commercially available SAE grade 20W40 mineral-based lubricating oil. Knowing the SO2 concentration in the exhaust, the air and fuel flow rates, the lubricating oil consumption rate can be calculated in real-time, i.e. on a second-to-second basis. Use of RTOC on the locomotive engine application has proven to be a cost-effective tool for mapping steady-state lubricating oil consumption rate. Where traditional volumetric oil consumption measurement techniques can take several days to obtain the oil consumption rate from a single operating point, the RTOC technique takes only about 10 minutes per operating mode. Applying this technique, the test duration can thus be tremendously compressed, as compared to the volumetric technique. In addition to cost savings, the repeatability of the data is much improved by applying this novel technique. In this program, steady-state oil consumption was determined at 10 steady-state operating conditions typical of North American freight locomotive operation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
