“…Passenger and commercial vehicles on the road represent a large fraction of the global energy consumption. The current tendency in new developments of internal combustion engines is to make engines more adiabatic [1], increasing the indicated work and the exhaust flow enthalpy, which can be later recovered via thermoelectric generators [1][2][3][4] or Organic Rankine Cycles [5,6]. Another trend is the hybridization of vehicles [7,8].…”

Significant reduction in fuel consumption and NOx emissions can be achieved just by changing the driving along the road. In this paper, dynamic programming is employed to find two different driving profiles optimized for fuel consumption and NOx creation minimization in a diesel vehicle. Results, show that the fuel reduction driving cycle leads to fuel savings of 4% compared with the average consumption with arbitrary driving. The NOx reduction driving profile improves the emissions of arbitrary driving by a 34.5%. NOx oriented driving profile improves the emissions of the fuel-oriented cycle by a 38% at the expense of a fuel consumption penalty of 10%. This result points out the difficulty of a simultaneous NOx and fuel consumption reduction, stressing the efforts to be done in this field during the following years. Strategies followed and conclusions drawn from this paper are relevant concerning vehicle autonomy integration.

Thermal electricity generation (TEG) is a potential method to utilize energy emitted from the built environment. This work presents a prototype of the low-cost full-day power generation solar building component, which can be integrated as the building fabric or as a part of the solar panels. The size of the prototype is 0.04 m2. The overall cost is less than 25 USD. The prototype is tested in various environments to validate its performance. The first experiment tests its performance under the radiation of a high-temperature source, the prototype can generate the highest voltage of 0.8 V. In onsite experiments, it can reach a maximum value of 10 mW/m2 under sunlight. It can also work at night depending on the thermal radiation of the environment. It can also be used in different weather; the performance is even better than the nighttime. The experiments indicate that radiation heat transfer has a stronger influence on energy conversion than the convective heat transfer. The relative humidity has a certain influence on its performance, but there is no obvious effect of radiation heat transfer. Although the prototype has great potential, there are still limitations, and this article also discusses the problems. Meanwhile, this article also points out possible directions for improving design in the future. The results in this article might be helpful for zero-energy buildings and low-carbon buildings.
