Use of Linseed Oil Additives in Diesel Fuel to Reduce Greenhouse Gas Emissions

In the context of fossil fuel depletion and growing environmental concerns, the study of alternative energy sources, especially biofuels, is particularly significant. Given the global challenges, this work examines the effects of a blended biofuel produced by adding linseed oil to diesel on the operational and environmental performance of a diesel engine. During the experiments, the physical and chemical properties of the initial components and their mixtures were determined, followed by engine testing on the engine stand in the external speed characteristic mode and in a 13-stage test cycle. Evaluation of the data obtained showed that the addition of linseed oil reduced exhaust gas smoke opacity and nitrogen oxide emissions, while causing a slight increase in fuel consumption and in carbon monoxide and unburned hydrocarbon emissions. To balance these effects, optimisation of the blended biofuel composition using the convolution method determined the optimal component ratio, achieving the best balance between fuel efficiency and reduced harmful emissions. The results of the study demonstrate that the use of linseed oil as a component of blended biofuel for diesel engines has the potential to mitigate the environmental impacts of transport.
