Biodiesel: A Sustainable Alternative to Fossil Fuels for Internal Combustion Engines

This article discusses the limitations and increasing costs of petroleum and fossil fuels for internal combustion engines, and highlights the urgent need for alternative fuel sources. It emphasizes the environmental and health issues caused by diesel fuel emissions and discusses biodiesel as a promising alternative. Biodiesel, derived from plant seeds or biomass through esterification, is a renewable, oil-free fuel that can be blended with diesel. The share of biofuels in the automotive industry has been growing rapidly due to environmental, social and economic concerns. Various approaches to using vegetable oils as biofuels in internal combustion engines have been explored, including pyrolysis, micro emulsification, and esterification. The study investigates the ignition characteristics of conventional diesel and biodiesel blends, with experimental results showing promise for reducing environmental impact and conserving resources.
