The Start of Combustion Prediction for Methane‐Fueled HCCI Engines: Traditional vs. Machine Learning Methods

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this work, 11 regression models based on machine learning techniques were employed to provide a fast‐response and accurate model for the prediction of the start of combustion in homogeneous charge compression ignition engines fueled with methane. These regression models are categorized into linear and nonlinear types.
