AB - The air pollutant emissions of a motor vehicle do not only mean the emissions from the engine used for propelling the vehicle. Another possible source is the passenger compartment heater. In the focus of our research, we investigated the effect of mixing gasoline-powered cabin air and ethanol (E10, E30, E100 on a volumetric basis) on the emissions of the equipment. Among the pollutant components examined, there were conventional components and so called not-conventional components. The chosen length of the test was 1800 s, while the intake air parameters temperature (tin) and relative humidity (h) have been kept constant (tin = 15 °C, h = 30%). Bioethanol mixing has a significant reducing effect on NOx (oxides of nitrogen) and CO2 (carbon dioxide). As for the components CO (carbon monoxide), THC (total hydrocarbons), CH4 (methane) and N2O (nitrous oxide), the values of the components reach usable values only in the start-up and burnout phases, while in the stable-operation phase, their values are outside the limit of detectability. A small part of THC is only CH4; a more significant part is NMHC (non-methane hydrocarbons). The results of the developed vehicle fleet model for calculating the GHG (greenhouse gas) emissions of a vehicle fleet equipped with such a device showed that the fleet’s GHG emissions are less than 1% of the annual emissions from the combustion of transport fuel.

This kind of heat engine transforms the chemical energy content of liquid fuels into heat energy. The combustion process and the emission of such a device is in focus in this study, which would be the first part in a greater project in the field. Therefore, some relevant parameters have been established. Relevant cycles have been chosen for the kinds of heat engines. It means a normal mode cycle for the stationary device and a WLTC cycle in the case of the direct injection gasoline engine. Fuel used was the same for both. This heat transfer process is such, that the combustion seems to be quite simple and rough in the stationary device compared to that of in internal combustion engine. This means an inhomogenous combustion with non-premixed flame at a low combustion temperature. This situation affects the emission characteristic accordingly, so causes low NOx and relatively high particle relevant emission comes out from the device. As far as the device's particle relevant emission is concerned it would be suitable for further investigation described at the end of the article.

A constantly growing trend is foreseen through 2050 worldwide as for using bio-based energy or fuels. Questions can arise before using these kinds of fuels in connection with the use of clean water or in terms of soil degradation, plant nutrients. It is also questionable whether they can be useful regarding their usage. First-, and second generation liquid as well as third generation gaseous bio-based fuels will be in focus in this article. They will be analyzed from physical-chemical properties and pollutant emission points of view.
