EXPERIMENTAL INVESTIGATION OF THE USE OF WASTE MINERAL OILS WITH ORGANIC-BASED MANGANESE ADDITIVE AS A FUEL IN DIESEL ENGINES

Abstract

In the world, 45 million tons of mineral oil are consumed annually, and the vast majority of these oils are made
up of petroleum-based products. Only a small part of these waste mineral oils that are produced after use are
recycled while a large part is used in blending with other fuels in the energy consuming cement, lime, ironsteel and energy sectors. The thermal values of waste mineral oils are equivalent to the thermal value of fuel
oil. However, for fuels such as density and viscosity, it is necessary to adapt to the system to be used for
critical physical properties. It is possible to improve the physical properties of waste mineral oils by pyrolysis
and cracking in conjunction with various catalysts and to use them as fuel. In this study, engine oils used in the
first 10,000 km of the vehicles were used as waste mineral oil.The collected waste mineral oil is filtered with a
paper filter to remove large particles. Pyrolysis or cracking has not been applied for waste mineral oil. An
organic-based Mn additive is synthesized to improve the properties of the waste mineral oil. The blending of
the Mn additive with the waste mineral oil at different doses (4-8-12 and 16 ppm) improved the viscosity of
the waste oil and the flash point. The resulting fuel was evaluated for emission using different loads in a 5 kW
capacity generator to compare with standard diesel fuel and to determine the effect of Mn addition. In the
experimental study, it was observed that the emission characteristics of the fuel obtained from the waste
mineral oil were worse than the diesel fuel but some improvement with the Mn addition. As a result, it appears
that the use of waste mineral oils in engines due to fuel standards is unsuitable. It is also hopeful that it can be
developed together with additives..
