Combustion System

The Combustion System course provides a comprehensive understanding of combustion processes used in internal combustion engines. Participants learn the fundamentals of fuel combustion, air–fuel mixing, ignition, flame propagation, and heat release. The course explains combustion chamber design and its influence on engine performance, efficiency, and emissions. It covers combustion characteristics of gasoline and diesel engines along with different combustion modes. Participants understand fuel injection, spray characteristics, atomization, and air-motion effects on combustion. The course introduces ignition systems, injection timing, combustion timing, and pressure development inside the cylinder. It explains abnormal combustion phenomena such as knocking, pre-ignition, and combustion instability. Participants learn methods for analyzing and optimizing combustion efficiency and fuel economy. The course also covers combustion-related emissions such as NOx, CO, HC, and particulate matter and their control techniques. Practical concepts related to combustion testing, engine calibration, diagnostics, and performance improvement are also included.
