5 FAQs about [Elastic energy storage for internal combustion engines]
What is a kinetic energy recovery system?
The system was conceived to recover the vehicle kinetic energy during braking phases, to be re-used in successive vehicle acceleration phases, so as to reduce the power demand to the internal combustion engine, and, as a consequence, the related fuel consumption and pollutant emissions.
What is the difference between electrified and internal combustion engine vehicles?
Unlike electrified vehicles, internal combustion engine vehicles are not equipped with generator, electric motor and batteries of adequate power and capacity to allow the conversion of the vehicle kinetic energy into electric energy, as well as its storage and re-utilization for vehicle propulsion.
What percentage of transport energy will come from combustion engines?
Nevertheless, 85–90% of transport energy is still expected to come from combustion engines powered by conventional liquid fuels even by 2040.
How much exergy loss occurs during combustion?
However, in real engine conditions, in addition to the main exergy loss during combustion, the exergy loss in terms of heat loss, exhaust gases, and friction loss is responsible for 5–15%, 12–20%, and 4–8%, respectively [8, 10], as shown in Figure 1.
What is kinetic energy of a vehicle?
The kinetic energy of a vehicle, if recovered and not dissipated as heat by the traditional braking system, can be efficiently employed for successive vehicle acceleration phases or for general vehicle energy requirement, and could substantially contribute to lower the energy consumption of the vehicles and the pollution associated.
