Abstract
Currently automotive technology is moving more and more from conventional combustion engines to hybrid and fully electrical power drives. The low battery capacity of conventional batteries causes small operating ranges and constrains electrical support in hybrid vehicles.
One possibility to increase the range of electric cars on top of energy recuperation during braking operations is to generate electric energy directly using a generator driven by a range-extender combustion engine. Continuous reduction of emissions and fuel consumption forces the application of supercharged combustion engines with low numbers of cylinders. However, this causes undesirable torsional vibrations even in hybrid and range extender concepts.
The pCPA-concept developed and engineered at the Technische Universitiit Miinchen (TUM) is a new type of pendulum-type absorber suitable for applications in highly downsized and downspeeded conventional powertrains as well as for hybrid and range extender combustion engines. The pCP A eularges the effective range of pendulum-type absorbers and improves the effectiveness and acoustical performance particularly in transient load states and in operational areas with low rotational speeds.
