Special Issue Information

Dear Colleagues,

In the face of increasing environmental pressures, especially in energy, great efforts must be made to achieve long-term development. It is universally acknowledged that long-term development can only be reached through sound environmental management, that is, sustainable development, which is especially important in fuel consumption and pollutant emission and is the title of this Special Issue.

Rapid global economic growth has led to social prosperity and an increasing demand for energy which is rapidly depleting the global reserve of petroleum fuels, making how to reduce or adjust fuel consumption a matter of urgency.

Pollution caused by emissions is one of the world’s largest health and environmental problems. The amounts and types of pollutant emissions change every year. These changes are caused by shifts in the nation's economy, industrial activity, technology improvements, traffic, and many other factors. 

Sustainable development requires the minimization of fuel consumption and the pollutants generated, as well as waste and toxic emissions of pollution, throughout the entire production and consumption process. Pollutants include carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), sulfur dioxide (SO2), and so on. There are also large amounts of compounds, which have been determined to be hazardous, called air toxics.

Furthermore, the benefits of sustainable development are also felt across a wide cross-section of human health and well-being, including reductions in pollution- and environment-related diseases, improved health outcomes, and decreased stress.

This Special Issue welcomes high-quality, process-oriented, and hypothesis-based submissions that report results from original and novel research and contribute new knowledge to help address problems related to fuel consumption and pollution caused by emissions under the sustainable development goals at a regional or global scale.  Discussions of the effects of fuel consumption and pollutant emissions under the sustainable development goals are welcome.

Research areas may include (but not limited to) the following: 

  • Low carbon fuel consumption;
  • Clean utilization of fossil fuels;
  • Hydrogen fuels;
  • Air pollution;
  • Emission reduction;
  • Harmless treatment of combustion wastes;
  • Sustainable development in fuel consumption.

We look forward to receiving your contributions.

Exhaust gas recirculation (EGR) has been an efficient emission treatment strategy employed in internal combustion engines (ICEs) to cope with NOx emission limits since the introduction of Euro 4 regulations for heavy-duty commercial vehicles. A portion of the exhaust gas is fed back into the intake port, replacing O2 in the fresh air with inert CO2 from the exhaust gas, resulting in a reduction in the combustion temperature and, hence, a reduction in NOx emissions. Considering the high exhaust temperature, this process increases the charge mixture temperature and degrades the volumetric efficiency of the engine. EGR coolers have been introduced as vital parts of EGR exhaust treatment systems with the aim of reducing the intake port temperature to increase volumetric efficiency and further reduce combustion temperatures. EGR coolers are heat exchangers (HXs) that generally employ engine coolant to reduce the EGR temperature with effectiveness values around 0.7~0.85 and downgrade with engine usage owing to soot deposition. Increasing the effectiveness of the EGR cooler has a positive effect on engine volumetric efficiency and reduces NOx, particulate matter (PM), and fuel consumption. The current study involved the design of a microchannel HX for a 500 PS heavy-duty Euro 6 diesel engine EGR cooler. The mechanical and thermal-hydraulic design calculations of the proposed HX were performed using Mathematica software. The optimum HX dimensions for the required boundary conditions were determined, and the performance of the EGR cooler was analyzed for the current and proposed options. Furthermore, Diesel-RK software was used to model the engine performance with NOx, PM, CO2 emissions, and fuel consumption predictions. The results show that the newly proposed microchannel HX design improves NOx, PM, and specific fuel consumption by 6.75%, 11.30%, and 0.65%, respectively. Full article
