Reduction of opacity in pollutant gas emissions in compression ignition engines by using biodiesel B5 and B10 based on algae. Ing. Desarro. [online]. 2020, vol.38, n.1, pp.212-223.  Epub 14-Jun-2021.

The constant search for alternative energy sources and the need to reduce the environmental impact of the automotive industry are substantial reasons for the incursion in the development of fuels that satisfy the requirements of vehicles with internal combustion engines with compression ignition, reducing negative effects to the environment. Under this scope, the present project is focused on reducing the levels of pollution of the exhaust gases through the use of mixtures of biofuels and diesel. For this purpose, algae plants (chlorella) recycled from third generation sources are used as raw material. The effects produced in the opacity indices and in the light absorption coefficient in a Mitsubishi Canter engine are evaluated, obtaining a reduction of 20,6% with B5 and 32,12% with B10, promising results for future research in the broad field of alternative energies.

Palavras-chave : algae; biofuels; light absorption coefficient; opacity.
