Effect of Load Level on Performance and Emission Characteristics of a Biogas Run Dual Fuel Diesel Engine

Energy consumption has increased steadily due to industrialization and rise in population of the world. Fossil fuel, especially crude oil, is the predominant energy source around the globe. However, the reserves of fossil fuel are limited and will be depleted in near future. Therefore, there is a great interest in exploring alternative renewable energy. Biogas, a renewable fuel, can be used in internal combustion engines for power generation. The utilization of biogas in diesel engines in dual fuel mode has colossal prospective if explored to the fullest. The current investigation unravels the influence of load level on the performance and emission characteristics of a biogas powered dual fuel diesel engine at different compression ratios. Results revealed that the performance and emission of a biogas powered dual fuel diesel engine improves at high load level. However, CO, CO2, HC, NOX emission and cylinder pressure increases at high load level.
