Scientists from Perm National Research Polytechnic University (PNRPU) have come up with a way to increase the environmental friendliness of aircraft engines. To more efficiently burn the fuel-air mixture, it began to be heated.
Usually this happens inside the combustion chamber, but scientists at Perm Polytechnic University have proven that heating before the chamber can be even more environmentally friendly. This approach reduces carbon monoxide emissions by 24%, but also slightly increases nitrogen oxides.
Tests were carried out on a special installation, where the fuel was heated by a heater with a capacity of up to 50 kW. Temperature and pressure sensors, flow meters were used to measure the combustion characteristics, and the composition of emissions was studied using a gas analyzer.
According to scientists, optimizing the process reduces the overall toxicity of emissions compared to traditional high-temperature combustion.
