Abstract
With a conventional drive, a very large proportion of the chemical energy of diesel fuel is lost in the form of thermal energy [1]. The thermal energy is either lost to the exhaust gas or dispensed to the cooling system. It is evident that this is where supplements to the conventional drive to improve the efficiency of energy use in vehicles can be applied.

WHR = Waste Heat Recovery. If the thermal energy of exhaust gas is utilized, it is called EHR = Exhaust Heat Recovery.

The scroll expander consists of a stator and a rotor. Both have a spiral contour. The rotor is mounted eccentrically. The expansion causes the spiral rotor to move in the stator.

mWHR = mechanical Waste Heat Recovery.
- 4.
eWHR = electrical Waste Heat Recovery.

The Seebeck effect is, so to speak, the reverse process to the much better known Peltier effect, in which temperature differences are generated by means of electricity.
