Analys och utveckling av drivsystemoberoende energiåtervinning

Abstract [en]

Limitations in energy recovery technology require extended research for development of existing and alternative solutions. This thesis project has treated valuing pneumatic drivetrain independent energy recovery system as a potential solution. The prototype built during this project uses a piston compressor to transform kinetic energy into compressed air. The compressed air was then stored in two air tanks and transformed into kinetic energy with an air motor on demand. The prototype was built on a rig using a high power electrical engine to simulate energy input from the wheels during braking. The air motor was then used to rotate a Volvo S40 engine simulating energy output to the wheels. To further illustrate how the technology can be implemented in vehicles and to emphasize the variety of pneumatic energy recovery solutions a 3D CAD model was designed and other components was reflected. Such as using a screw compressor instead of piston and also using the compressor as a motor reducing the number of components optimizing the system. The system storing the kinetic energy does not mean that the vehicle can manage without an ordinary brake system. The regenerative braking effect rapidly reduces at lower speeds; therefore friction brake is still required in order to bring the vehicle to a complete halt.Analyses of strength of strained components acknowledge that limited energy recovery is possible without redimensioning the driveshaft´s. The limitation is regulated by the original dimension for engine load, with subject to the CV joint. Optimum positioning of the compressor due to the limited space in a modern vehicle is behind the gearbox in conjunction with the gearbox outgoing pinion for short energy transportation.Electrical energy recovery system is the solution with the highest potential on the market today but electrical vehicles covers just a fraction of the vehicle industry doe to technical and infrastructural limitations. Drivetrain independent pneumatic, hydraulic or mechanical energy recovery systems lay the foundation of a common ground for all vehicles and other waste energy machinery to use one energy recovery technology. The market research indicates that this type of technology is up-to-the-minute.
