Investigation of the usability of alcohol additive aspiral oil biodiesel on a diesel engine

The global warming caused by the greenhouse gas effect is now regarded as the most important common environmental problem in the world. Greenhouse gas effect; The melting of the glaciers and consequently sea level elevations lead to global warming and climatic changes. In order to find solutions to the problems, there is an increasing interest in renewable energy sources. One of the most useful of these resources and the most ideal one is biodiesel . Biodiesel is produced from renewable sources such as vegetable oils which can be used in d- motors; sustainable, environmentally friendly, non-toxic and an alternative fuel for diesel engines that can be used without modification. This study uses biofuels produced from vegetable oils instead of petroleum-based fuels in the engine without a significant change in existing diesel engines provides. The fact that plant-based oils have close properties to oil-derived diesel fuel is an important factor in making these studies. In the study, bioavailability of bio fuel obtained by pyrolysis method, which is a vegetable oil, was tested in diesel engines. In addition, as a precaution against the decrease in oil resources and price increases, an alternative fuel that has renewable share that can be used in diesel engines and which is more compatible with the environment has been determined. In this thesis, biodiesel fuel was obtained from raw safflower oil which is vegetable oil by pyrolysis method. Obtained biodiesel and chemical properties were determined. Biodiesel and ethanol mixtures were tested at different speed intervals in a test setup with diesel engine. Performance and emission results are compared with diesel fuel and the results are evaluated. As a result of the study, it was concluded that using biodiesel mixtures as an alternative fuel is positive for the environment.
