The study incorporates sensitivity analysis to assess the impact levels of various parameters on fuel consumption, thereby highlighting the most influential factors. In addition, this study addresses the impact of noise and implements data cleaning techniques to ensure the reliability of the obtained results. To validate the accuracy of the predictions, the study performs several metrics and validation process, including comparisons with computational fluid dynamics (CFD) results and experimental data. Comprehensive comparisons are made among neural networks (NN), random forest regression (RFR), and Gaussian process regression (GPR) models, taking into account the complexity associated with fuel consumption predictions. The findings demonstrate that the GPR model outperforms the others in terms of accuracy, as evidenced by metrics such as mean absolute error (MAE), mean squared error (MSE), Pearson coefficient (PC), and R-squared (R2). The GPR model exhibits superior predictive ability, accurately detecting and predicting even individual data points that deviate from the overall trend. The significantly lower absolute error values also consistently indicate its higher accuracy compared with the NN and RFR models. Furthermore, the GPR model shows a remarkable speedup, approximately 1.7 times faster than  \n* Corresponding author  \nE-mail address: [j.xie@derby.ac.uk](j.xie@derby.ac.uk) (J.

Introduction  \nDiesel combustion is a critical process in internal combustion engines, and optimizing its performance is of great importance to achieve high fuel efficiency, less emissions and improved overall thermal performance. Traditional approaches to fuel consumption predictions mainly rely on semi-empirical formulas or physical models. However, these methods often lack accuracy and are limited in their ability to capture complex relations between engine parameters and fuel consumption [1–7]. To address these limitations, ML models have emerged as a promising alternative for fuel consumption predictions.
