Abstract. The paper reviews a relevant problem of providing a higher quality of people's living in the northern regions by the application of the modern technologies within transport in order to improve its environmental performance and efficiency. The aim of the research is to substantiate methods of increasing the adaptability of vehicles to variable low-temperature operating conditions based on a neural control system of preheating and maintaining the optimum temperature of technological fluids by SHF radiation and improving diesel fuel properties by introducing a multifunctional additive. It has been found that SHF radiation influences the physical and chemical parameters of diesel fuel, as well as the engine output parameters. SHF radiation results in a reduction of fuel consumption to 7%, smoke from the exhaust to 15%, and nitrogen oxide emission to 30%. A conclusion is made that using SHF radiation for technological fuel preheating is essential. An approach has been developed that improves low-temperature properties of diesel fuels and increases engine operation efficiency under severe climatic conditions by introducing a multifunctional additive. The additive will enable a significant decrease in fuel consumption under low-temperature operating conditions and a complex improvement of fuel properties.

“…Regarding the thermal need analysis, several authors have studied it (Iskandar, 2010;Li and Sun, 2013;Marcos et al, 2014;Mezrhab and Bouzidi, 2006;Torregrosa-Jaime et al, 2015). However, they focused on air-conditioning needs (since it was the important aspect for conventional cars) but neglect heating needs.…”

Interest for cabin thermal needs has strongly increased for the past 10 years, particularly due to heating. Indeed, the development of electric and hybrid vehicles stressed the need to rethink the cabin thermal design and the HVAC, this high-consuming auxiliary, which can dramatically decrease the vehicle electric range. Thus, this paper presents a detailed transient and mono-zonal model of a car cabin in order to predict the thermal needs. The model is developed using the MODELICA language via the DYMOLA environment. It considers conduction, convection, radiation heat transfers as well as the HVAC and water vapor impacts. The different assumptions of the model are discussed and important considerations usually not discussed are highlighted. The thermal loads are also analyzed. Finally, the heating and cooling thermal needs are computed for steady state mode and for convergence mode as well as for varying recirculation ratios. This work is useful to better understand the whys and wherefores related to the cabin thermal needs.

“…[6] observed that the greenhouse-control system operated by solar battery, can be used to remove hot air from the car during idling of the engine. Torregrosa-Jaime et al [7] developed a thermal model of cabin of automotive minibus and studied the dynamics of cool-down and warm-up in outdoor conditions. They concluded that major cooling load requirement is due to the solar radiation and solar radiation plays an important role in thermal environment in the cabin.…”

Sunny conditions create the heating to the car body and rise in its average internal temperature resulting discomfort to the driver and passengers. It was observed that inside temperature of the car cabin rises up to 60 0 C -70 0 C in summer during parking conditions. Consequently, it may be fatal to the life of a child, left inside the car due to some reason as reported in various news resources. In the present investigation, air circulation and temperature distribution in car cabin was studied to address the problem of heating and ventilation in the car cabin. The possible design criteria were instigated for geometrical consideration as an inlet vent was considered below the front windshield and outlet vent at below rear windshield. In another design concern, two outlet-vent were considered; one below and above the rear windshield.It was observed that air circulation in the rear compartment was more effective in comparison to the front compartment improving the overall air circulation with increase in inlet velocity. Also an increase in the uniformity of internal temperature distribution was observed with the increase of incoming airstream velocity. The temperature difference marginally improved for modified design conditions. The accumulated heat in the car cabin can be reduced appreciably with the provision of vents in the compartment.
