The demand for energy is rising daily throughout the world. Using coal and petroleum-based fuels to supply this high energy demand is exceedingly challenging. The entire world the focus on energy is currently changing to nuclear power and renewable energy of power due to the knowledge of the effects of global warming and environmental pollution the faster consumption of fossil fuels. However, the processing of raw materials and waste materials for nuclear energy needed caution, so the Renewable energy is the only choice of power. The finest alternative fuels are biogas and biodiesel. Diesel engines can consume the fuel directly, with or without modifying the current engine. In the proposed effort, investigations will be performed using a 4-stroke, single-cylinder diesel engine made by Kirloskar (AV1model). Diesel and biodiesel pilot fuel were combined with biogas as the main fuel. The experiment was carried out to measure a number of factors, including brake power, energy conversion efficiency, and emission, including the amount of CO, CO2, HC fine particles, and NOx in Exhaust gases. Additionally, the impact of replacing emissions from diesel was investigated.
