Program Overview
This intensive program provides engineering professionals with a comprehensive understanding of combustion processes in internal combustion engines, covering the fundamentals, chemical kinetics, gasoline and diesel combustion stages, heat-release analysis, knock behaviour, combustion curve interpretation, and advanced combustion modes such as HCCI, PCCI and LTC. Blending conceptual clarity with real-world automotive and powertrain case studies, the course builds strong situational awareness around fuel properties, calibration challenges, emissions constraints, and engine design impacts on combustion quality. Participants also engage in hands-on simulations and diagnostic exercises to analyse P–θ diagrams, identify knock, evaluate combustion stability, and recommend engineering improvements. The program is designed to help teams improve engine performance, reduce emissions, optimise calibration, and solve real combustion problems faced in industry.
