The preparation and optimization of novel jasminum officinale biodiesel blends performance in CI engine: An experimental study

Abstract

Fuels for transportation and the need for power are two of the largest contributors to global greenhouse gas emissions. Nowadays, biodiesel has shown a ray of hope for replacing diesel to minimize the harmful emissions formed during the combustion of diesel fuel in compression ignition (CI) engines. This study has focused on the production and preparation of Jasmine oil biodiesel (JB) along with its combustion in the diesel engine. The prime contribution of the present study is to maintain the performance and reduce the harmful emissions of biodiesel blends fueled CI engine. The experiments were performed on a 1-cylinder, 4-stroke diesel engine using diesel and biodiesel blends such as (JB-25, JB-50, JB-75 and JB-100 on a v/v basis) at various loads. The findings of output and emission parameters are compared with the conventional fuel (diesel) output results. In this study, Taguchi and ANOVA analysis have been performed with experimental data to model and determine diesel engines' optimum working conditions (load, compression ratio, and blending ratio) for reduced emissions with slight deterioration of performance. The obtained results revealed that engine performance was in line with diesel with JB-25 and with other ratios, the performance characteristics deteriorated. However, the rate of heat release is slightly lower with a shortened ignition delay. The primary benefit is the reduction of harmful emissions i.e. hydrocarbon (HC), carbon monoxide (CO), oxides of nitrogen (NOx) and smoke. It can be concluded that Jasmine oil biodiesel would be a suitable fuel for reduced engine emissions without highly affecting engine performance.
