Biodiesel has become a prime source of alternative fuels and is becoming a big source of renewable energy for the future. Various alternative fuels have been studied whether partially/completely to replace diesel fuel. Soybeans-based vegetable oils are proposed as promising alternatives to diesel because they are manufactured in rural areas. Oil manufactured from soybean may provide opportunities for self-employment. The impact of biodiesel/diesel blends on engine performance and combustion, have performed experimentally at various speeds and loads. Volumetric percentage of diesel/biodiesel blends: D80B20 (80% diesel-20% biodiesel) and D70B30 (70% diesel-30% biodiesel) were ready to power a single-cylinder DI engine. The test has been done on four strokes, single-cylinder, multi-fuel, VCR engine. The prepared samples were tested at a constant speed in CI engine by varying the loads and compared with the diesel fuel additive; the engine results show a decrease in BTE and an increase in BSFC with an increase of biodiesel ratio in the mixtures. It is found out that BSFC for D70B30 is more. The engine performance in the case of 30% biodiesel blend is better. The emission of Exhaust Gas Temperature (EGT) in biodiesel blend reduces than diesel. Due to low ignition delay and low calorific value of biodiesel, the cylinder pressure is slightly reduced for higher percentage of biodiesel in the blend. At different loads, a consequent decrease in Mechanical Efficiency and Engine Speed (RPM) is observed with an increase in engine torque. All the characteristics of the engine performance are displayed graphically.
