Research conducted around the world shows that energy harvesting (EH)
systems can be used in modern vehicles powered by combustion, hybrid or electric
engines. The efficiency of modern combustion engines is about 40%, the rest of the energy
is lost and can be recovered to some extent. Therefore, the search is ongoing for systems
that will use this part of the energy to power specific systems or microsensors installed in
the vehicle. The article presents the possibilities of energy recovery from such vehicle
systems as: energy recovered during braking, damping energy in the vehicle suspension,
energy recovery from the exhaust system of an internal combustion engine and energy
from the vibrations of the internal combustion engine. Based on the analysis of the
literature on the presented research of various scientific centers and the author's
experiment, it can be concluded that there is a huge potential for obtaining thermal energy
from the engine exhaust system and the vehicle suspension system. A field that has not
been explored much, but according to the authors also has energy potential, is energy
recovery from the combustion engine suspension system in the vehicle\'s engine
compartment. Preliminary research shows the possibility of mounting the energy recovery
system in the engine compartment and the potential possibility of obtaining electricity in
certain operating states of the combustion engine.
