If you take more data, be sure to monitor fuel air ratio, and intake manifold temperature and pressure. So you need to look at the fuel air ratio, which needs to be measured, and be sure that your data is reliable and repeatable. Your results should then obey the above relationship. But the main things active here are the fuel air ratio and the heating value, the later of which should be easily calculated. Intake density would be affected somewhat by fuel evaporation (temperature effect, as alcohols have higher heats of vaporization), depending on what kind of fuel injection you use. So the main things different are the density, fuel air ratio and heating value. The engine volumetric efficiency is a function of engine speed for a given cam, and should also be the same for all fuels, The indicated efficiency should close to the same for any fuel, unless you changed spark timing. This Special Issue will deal with innovative experimental applications and systems belonging to the solar thermal engineering field.įor full load, as you apparently have, the fmep is only dependent on engine speed, and should be the same for all fuels. Advancement in solar thermal engineering is therefore paramount to improve the efficiency, reliability, and sustainability of solar collectors and all related energy systems. The only way to meet this global thermal demand without contributing to climate change implies the utilization of renewable sources, and in particular of the solar source, which is the most abundant energy resource on Earth.

The global commercial low-temperature heat consumption is estimated to be more than 10 EJ per year for hot water production alone, while industrial energy consumption in industrialized countries accounts for 30% of the total required energy in Europe, two-thirds of this energy consists of thermal energy. Apple Software Update is a software tool by Apple that installs the latest version of Apple software. The growth in energy consumption over the past 20 years has been significant, and demand for energy will continue to grow in the future.
I would like to invite you to submit contributions to a Special Issue of Energies on the "Experimental Evaluation of Solar Thermal Engineering”.
