To reduce the usage of gasoline extracted from fossil fuel resources, there is a need for a sustainable alternative fuel that has the potential to replace gasoline. In this work, the oil extracted from the leaves of Basil oil (BO), which gives a low cetane number, was investigated in the port fuel injection installed spark-ignition engine to study its feasibility as a replacement for gasoline fuel. Initially, the basil oil was taken to GC_MS and FTIR analysis to study the chemical compounds and types of chemical bonds present in it. Then three BO blends were prepared by blending BO in the ratio of 10:90, 20:80, and 30:70 with gasoline. The blends were undergone a phase separation test and the fuel properties of sole BO and its blends were measured. The blended BO fuels were tested experimentally to find out their impact on the performance, emission, and combustion characteristics of the engine. The results show that the performance of the BO blends is lesser than that of gasoline. At maximum engine brake power, the BTE of BO10 (Basil oil 10% + Gasoline 90%) is 25.08% which is 1.74% lesser than the BTE given by gasoline. The NOx emission of BO10 is 318 ppm which is about 6.4% lesser than gasoline. The levels of CO and HC emissions are increased with an increase in the blending ratio of BO in the gasoline. Though the BO blend performance is not equivalent to that of gasoline, a suitable engine modification can improve its performance.
