A current rechargeable battery for EV cannot provide high energy density and the operational durations required. In this study, we develope a linear engine and generator for portable power pack for RE-EV. To increase the efficiency and endurance, we made a piston and cylinder sleeve by ceramic materials. Efficiency is relatively high because linear engine don’t have crank mechanism compared with rotary engine. We made prototype engine and had experiments to know moving characteristic about the Linear Engine. It was possible to operate velocity at 50 ㎐ at the firing and pressure in cylinder was 16bar.
