- Abstract
The purpose of this research is to develop and apply an exhaust gas preheating module based on the principle of thermal induction, with the aim of reducing nitrogen oxide (NOx) emissions in diesel engines. The study explores the use of an induction coil, specially designed and integrated into the exhaust system, to increase the temperature of the exhaust gases. Thus, it improves the efficiency of the catalytic reduction process of emissions by optimizing the heating of AdBlue microdroplets, a reduction agent used in emission control technology. The induction process is achieved by placing an electromagnetic coil around or inside the exhaust piping. When an electric current pass through the coil, a variable magnetic field is generated which, in turn, induces heat in the exhaust pipe's metal. This heat is then quickly transferred to the AdBlue vapors and compressed air, effectively preheating the AdBlue solution during cold engine operation. This preheating improves the performance of the catalyst in the subsequent injection of AdBlue into the exhaust gases, thus contributing to a significant reduction in NOx emissions in diesel engines.
