Extensive research has been carried out with regard to the composition of the exhaust gases of Diesel engines in operation with biodiesel in relation to the operation with the conventional diesel fuel. Producing biodiesel from different raw materials and different technological biodiesel production processes can result in different individual physical and chemical characteristics of fuel. Generally, it can be said that the use of biodiesel (and mixtures) reduces the overall toxicity of the exhaust gases in relation to the operation of the engine with diesel fuel, and this is a significant environmental potential of biodiesel as a fuel for Diesel engines. However, there is a diversity of research results, due to different factors. The paper reviews and summarizes the relevant literature on the mentioned research that can contribute to the explanation of these effects. It also points to the need for a very careful selection of biodiesel for use as a Diesel engine fuel.
