| Abstract | The internal gear pump has been widely used in vehicles because of durability and downsizing, but torque and noise of rotor in the pump have been required to be improved for fuel efficiency. In this study, shape function of the rotor with multiple profiles (ellipse 1-involute-ellipse 2) was derived, and performances (flow rate, irregularity, specific sliding and pressure angle), which were related to torque and noise, were calculated by a prediction algorithm of theoretical equations. The optimal ranges of each design parameter were determined on the basis of analysis results of about 500,000 cases of rotor profiles by using the automated design and the multiple calculation programs developed. Based on the analysis results, the rotor profiles were suggested for improving fuel efficiency, and the performance tests for them were carried out for verifying the analysis. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
