Abstract
To reduce the dependency on fossil fuel-derived petroleum energy sources, the vegetable oil obtained from plant-based products can be regarded as potential alternate bioenergy sources. In this work, the bio-oil with low viscosity and low cetane number is tried as an alternative to gasoline fuel to study their effect on a spark-ignition engine`s performance, emission, and combustion characteristics. The camphor oil (CMO) extracted from the woods of the camphor tree is used as a partial substitute to gasoline by blending it with gasoline in the ratio proportions of 10:90, 20:80, 30:70, and 40:60 by volume. Initially, the fuel properties are measured for camphor oil, and a blend stability test is performed on camphor test blends to study their suitability as a fuel. Then the experimental study is performed with camphor oil blends to analyze their effect on the engine characteristics. The results show that the 10% camphor oil blend`s performance is comparable to that of gasoline. The BTE of CMO10 is 26.54% at full load, which is lesser than gasoline, whose BTE is 26.82%. For the same load, the NOx emission of CMO10 decreased by about 3% whereas CO and HC emission slightly increased by about 1.2% and 2% compared to that of neat gasoline. The experimental analysis found that camphor oil can be used up to 10% as a blend with gasoline fuel. Even though the performance of CMO10 is very slightly lesser than gasoline, it can be used with slight engine modifications to give gasoline-like efficiency.
