Free-piston linear generator and the development of a solid lubrication system

Abstract

The free piston linear generator is a new electromechanical generator. It converts chemical energy into electrical energy by means of a combustion process, a linear generator and a gas spring. The free piston linear generator doesn´t use any crankshaft, which is responsible for a lot of losses. Thereby the technology aims to have better properties than other electromechanical generators: higher efficiency over wide range of operating points, better noise-vibration-harshness, package … This publication deals with Free-piston linear generator and the development of a solid lubrication system 2 the explanation of the concept, the characteristics of a free piston linear generator and one of the challenges in the development. In order to use a port scavenging the emission issue is the challenge and has to be solved. One possible solution is the use of solid lubricants to substitute motor oil. On this way The development methodology and one aspect of the development will be explained.
