Abstract- The comfortability of car passengers, reduction of fuel consumption in order to reduce the emission of CO2, and increasing the efficiency of fuel usage are the main goals of car manufacturers. Therefore the combustions in internal combustion engines must be done at temperatures as high as possible. These high temperatures have negative effects such as impact, rattling status in gearbox, low-pitched sound in gearbox, and vibration of vehicles. These vibrations interfere with the comfortability of passengers. In order to reduce the unwanted vibrations as much as possible there is a need to uniform the radial velocity of the flywheel and the inlet torque to the gearbox. In this study the available methods are reviewed and a new approach is proposed which is the two-mass flywheel. The effects of this new flywheel are carefully investigated. The experimental results are compared with the numerical ones and a very good conformation is observed.
