The vehicle market is slowly adapting to the facts that there is a rising amount of consumers that would like to have real alternative cars. The vehicle concepts that would really have an influence to the CO2 output are battery electric vehicles with or without range extenders as well as vehicles specifically designed as series hybrids. A range extender (REX) is an auxiliary power source of an electric vehicle (EV) to increase travel-distance. Crank less mechanism which facilitates variable stroke length and a piston can be controlled on each stroke by proper fuel injection timing. Unlike conventional engines that the piston motion is determined by the crank system, the piston motion of Š 2017, IRJET

Boru Jia et.al (2014) had described that free piston linear generator as an alternative to conventional engines, free-piston engine generator (FPEG) is a promising power generation system due to its simplicity and high thermal efficiency. The new method to start the engine by mechanical resonance. A closed-loop control model was developed and implemented in a prototype FPEG which was driven by a linear machine with a constant driving force. Un-Jae Seo, .et al (2015) had explained that the free piston linear generator is a new range extender concept for the application in a full electric vehicle. The ISO 9001:2008 Certified Journal
