| Abstract | The depleting of fossil fuel reserves and increasing environmental concerns have continued to stimulate research into biodiesel as a greener fuel alternative produced from renewable resources. In this study, the performance and emission characteristics of biodiesel blends of 10, 30 and 50 % from waste cooking oil based on hydrodynamic cavitation were compared to diesel fuel, and found to be acceptable according to the EN 14214 and ASTM D 6751 standards. The tests have been performed using an in-line vertical six-cylinder diesel engine at different engine speeds, ranging from 1000 to 2000 rpm under full throttle load. During engine performance tests, biodiesel blends showed higher brake specific fuel consumption (2.1–9.0 %) and exhaust gas temperature (1.0–6.8 %), while lower brake power (1.6–6.7 %), torque (0.6–5.2 %) and brake thermal efficiency (1.9–8.4 %) than diesel fuel. Engine emissions showed higher carbon dioxide (8.7–38.5 %) and nitrogen oxide (4.7–19.0 %) releases, but surprisingly decreased amount of carbon monoxide (3.3–26.3 %) for biodiesel blends compared to diesel fuel. Although higher carbon dioxide amounts were emitted, the use of biodiesel greatly reduced the life cycle circulation of carbon dioxide. Waste cooking methyl ester produced by using hydrodynamic cavitation seems to be relatively easy to scale up to higher production values, is energy efficient, time saving and eco-friendly, which results in biodiesel being a viable fuel for industrial production. The waste cooking oil-based biodiesel can also be used without any engine modifications. |

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.
