Description

Recently, environmental issues have been exacerbated by harmful exhaust emissions and increasing levels of carbon dioxide (CO2) from fossil fuels combustion. Renewable fuels are a possible substitute for limited fossil fuel resources because the use of biobased fuels will not only help mitigate fossil fuel consumption, but also reduce greenhouse gas (GHG) emissions, and therefore help to address issues related to environmental protection and sustainable development. The application of alternative fuels in internal combustion (IC) engines has gained interest over the years due to the potential for emissions reduction such as lowering particulate matter (PM) emissions. Energy crisis is among the biggest problems, leading the world to be unsafe and non-peaceful. The demand is increasing day by day. The available resources are rapidly decreasing and indication is, soon will be vanished. In such situations, more attention is needed to be given towards renewable energy sources. Fossil fuels are used on a large scale in the world, but unsustainable because they increase CO2 level and accumulate greenhouse gases which make the environment unhealthy.
