This certificate certifies that five students - Milan Hazra, Kumar Shanoo, Saikat Bera, Sagnik Banerjee, and Soumen Paul - successfully completed an experimental study project on the combustion, performance, and emission characteristics of a variable compression ratio (VCR) engine under the supervision of their project supervisor Dr. Dipak Kumar Mondal. The preface acknowledges that research is an integral part of higher studies and the importance of studying internal combustion engines, which are constantly evolving. The acknowledgements thank Dr. Mondal and the mechanical engineering department for their support and guidance on the project.

3. PREFACE
Research is an integral part of any higher study. Based upon this ,the domain of I.C Engine also
changing day by day. And her our project work on research engine which is known as multi-
fuel variable compression ratio engine. It therefore becomes immensely important to study the
subject that has got important applications potentials to develop a solid foundation on
mechanical engineering department.
ACKNOWLEDGEMENT
At the very beginning We would like to express our sincere gratitude towards our respected &
honorable HOD, Dr. Dipak Kumar Mondal who devoted his time and knowledge in the
implementation of this project and gives us constant support and encourage to perform this
project. Nevertheless, the project was carefully guided by technical assistants of Mechanical
Engg. Dept. Besides it sir has given the opportunity to study & perform on this research works.
So ,all the members of this project group give their thankful acknowledgement.
