Compression Ignition Engine Fuelling with Graphene Doped Diesel-Hybride Biodiesel Blend: Performance Analysis

In response to climate change dictating the reduction of carbon footprint, the potential of rotten coconut oil as a potential diesel blend has been explored. The choice of rotten coconut oil steers clear of the food and fuel competition. With the principle aim of no frame power loss a blend of Cotton seed oil and rotten Coconut oil in 10% by volume each and Diesel by volume of 80% is created which ensures that on volume basis the lower calorific value suffers no loss. A compression ignition engine is operated with three fuels, Diesel, Blend and Blend with Graphene at constant speed of 1500 RPM and at three injection pressures of 175 bar, 200 bar and 225 bar. It is observed that at 175 bar injection pressure, a near 10% increase in specific fuel consumption is seen to completely neutralized by adding Graphene and the baseline Diesel performance is restored. At 225 bar pressure, engine specific fuel consumption seems to improve by about 5% on shifting from Diesel to blend which on adding Graphene results in near 10% improvement over baseline Diesel performance. Graphene seems to provide a clear improvement for the blended fuel to realize neat Diesel performance.
