In this work, experiments were carried out in line with Design of Experiments (DOE) standards to assess the performance and emission features 5% graphene nanoparticles added linseed biodiesel. The engine was operated blends B10, B20, B30 nano additives (designated as B10G5, B20G5, B30G5). To find parameter's optimum values, Desirability Function approach (DFA), Swarm Salp single objective, Multi Objective Bat algorithm (MOBA), Response surface methodology (RSM) D-optimal design employed. Advanced machine learning (ML) techniques employed anticipate these characteristics. It found that B20G5 had a better brake thermal efficiency (BTE), when compared other samples (and around 11% higher than diesel fuel at full load). emissions Carbon monoxide (CO) Hydrocarbon (HC) lower for blended (Around 23.52% diesel). comparison (RSM), overall coefficient determination (R2) value using Artificial Neural Network (ANN) high. As result, it revealed ANN typically RSM forecasting various factors affecting performance. outcomes achieved by objective (Salp algorithm) multi-objective algorithms. According algorithm, additive biodiesel mix its maximum Brake power (BP) produced highest BTE lowest Nitrogen Oxides (NOx) emissions. shows can be used easily without making any modifications engines.
