Measurement and Comparison of the Total Response of Bio-fuelled CI Engine with & without an additive

Abstract: Availability of pure air is everyone’s right, not only of the human beings but all animals living on the globe. The main source which pollutes the air is exhaust emissions from diesel engines. Also, the extensive use of fossil fuels results in its depletion and increase of green house gases and global warming. In this present context, the use of bio diesel produced from waste coconut oil is analyzed and conducted an experimental investigation of its performance and emission characteristics while using in a diesel engine with and without the additive. The additive used is 1heptanol which is readily available. The load test is conducted at different fuel injection pressure and angle and for B20, B40, B50, and B100 blends with 5%, 10% and 15% of heptanol. The doping of additive and higher injection pressure and angle gives better results, in both performance and emissions. Hence waste coconut oil biodiesel with heptanol can successfully be substituted for diesel fuel in future.
