Abstract: Diesel engine is a popular prime mover applied worldwide. It is necessary to find an alternative of diesel fuel in order to run diesel engines efficiently, as well as to reduce its prolusion to the environment. Biodiesel is such an alternative, which can be obtained from both edible and non-edible plants and crops, with some chemical processes, biodiesel properties can be modified to use as blends in diesel fuel. Selected biodiesel blends boost brake specific fuel consumption and decrease brake thermal efficiency in comparison to diesel. In most cases, the biodiesel has better results in carbon monoxide and hydro carbon emissions, although high cylinder temperatures also boost nitrogen oxides emissions. This analysis comes to the realisation that these modified biodiesels with better quality can be pumped in a specific proportion into a diesel engine without modifying the engine components. Therefore, the biodiesel is renewable, biodegradable, and non-toxic.

Keywords: diesel; biodiesel; combustion; engine; thermal efficiency; nitrogen oxides.
