Free piston linear generator in comparison to other range-extender technologies

The free piston linear generator is a new range-extender technology. It converts chemical energy into electrical energy by means of a combustion process and linear generator. Thereby the technology aims to have better properties than other range extenders. Therefore this publication deals with the explanation of the concept and the characteristics of a free piston linear generator and a comparison to other technologies. In order to compare the range extender systems, fuel cells, micro gas turbine and otto/wankel combustion, will briefly be presented, before being compared to the free piston linear generator

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

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. Thereby the technology aims to have better properties than other electromechanical generators. Therefore this publication deals with 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. The development methodology and one aspect of the development will be explained

Freikolbenlineargenerator Vom Proof of Concept ins Auto

Um die Grenzen der Traktions-Akkus zu überwinden, finden Range-Extender zunehmend Beachtung. Ein Forscherteam am DLR hat dafür einen Freikolbenlineargenerator entwickelt, der die Bewegungsenergie eines freischwingenden Kolbens einer Verbrennungskraftmaschine in elektrische Energie umwandelt. Als Höhepunkt der langjährigen Entwicklungsarbeit konnte das Team kürzlich den „Proof of Concept“ erbringen. Nun geht es um die Potenziale der Technologie sowie die offenen und die gelösten Herausforderungen

A new power generator for hybrid vehicles

This publication deals with the concept, the explanation, the development and the actual measurement results of a free-piston linear generator (FPLG). The free-piston linear generator is able to convert chemical energy into electrical energy by using a combustion process. In this publication the function and the characteristics of the free-piston linear generator will be explained first. Then the surrounding system and its effects on the FPLG are explained. This is important to understand the effect of every subsystem to the FPLG. In the next step the development based of the three base components, the gas spring [7], the linear generator [3] and the combustion [6] will be explained. Each chapter includes actual measurement results generated on a purpose-built test bench. At the end of the publication the current situation of the FPLG development and the further steps are presented

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

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
