The pursuit of increasing the efficiency internal combustion engines is an ongoing engineering task that requires numerous research efforts. New concepts injection or systems require preliminary investigation work using engines. These engines, usually single-cylinder, make it possible to isolate a single variable in complex mixture preparation process, thus enabling analysis changes being made....

the current curriculum for both medical and engineering students does not include any serious program for research and technology development, by which capable students can become a man of research and a man with high-tech skills as soon as possible. however, there are opportunities for several good experiences in iranian universities such as “research student clubs,” [2,3] which show that ther...
