In the study, they examined the use of oxygenated biofuels mixed with diesel in a 20 percent volumetric proportion, which proved a reduction of more than 90 percent in the production of black smoke emitted by vehicles.
Francisco Javier Martos, professor at the School of Industrial Engineering of the University of Malaga, is in charge of the analysis of soot nanoparticles emitted by the engine from the different biofuels studied: bioalcohols such as butanol, pentanol, or cyclopentanol, and bioketones such as cyclopentanone.
According to experts, the main characteristics of these biofuels are that they can be made from waste obtained from residual biomass such as used oils, algae, agricultural and forestry surplus or waste, and they are under carbon.
“Our research shows that the biofuels studied, which we obtained in the laboratory, in addition to producing very little soot, have an engine behavior similar to gasoline from any gas station, which means that there is no change that needs to be made. to it for it to work properly. normal way,” explained Martos.
He added that this work opens a new path that can reduce soot emissions from thermal engines and, thus, alleviate the environmental and public health problems it causes.
“The carbon particles emitted by the machines are expelled into the environment and remain suspended, affecting the climate because they increase the greenhouse effect and public health because they are not placed on the ground; they have a high probability of being banished by living beings,” he said.
This study “opens the door to using non-petroleum fuels and reducing pollutant emissions in vehicles,” he said.
