The Diesel Engine Combustion Gas Simulator (DECGS) course is a specialized high-tech training program designed for marine engineers to master the intricacies of engine performance and emissions management. As global environmental regulations like MARPOL Annex VI become increasingly stringent, the ability to optimize combustion and minimize exhaust gases—such as NOx and SOx—has become a critical skill for the modern engineer. This DGS-approved course utilizes advanced computer-based simulators to replicate the internal combustion processes of large two-stroke and four-stroke marine diesel engines, allowing engineers to experiment with variables that would be impossible or dangerous to adjust on a real ship.
The curriculum focuses on the relationship between fuel injection, air supply, and combustion quality. Trainees learn to interpret "Indicator Diagrams" and combustion pressure curves to identify technical issues like worn fuel injectors, incorrect timing, or poor air-fuel ratios. The simulator allows students to see the immediate impact of these faults on engine power, fuel consumption, and gas emissions. A significant portion of the course is dedicated to "Performance Tuning," where engineers learn to adjust engine parameters to achieve maximum efficiency while staying within legal environmental limits. This training is essential for those operating the latest generation of electronically controlled engines (ME and RT-flex engines).
Completing the DECGS course provides a significant technical edge in the maritime industry. It transforms an engineer from a basic operator into a technical specialist capable of saving shipping companies thousands of dollars in fuel costs and avoiding heavy fines for environmental non-compliance. This qualification is highly valued by technical superintendents and is an excellent asset for engineers aiming for senior management roles. By mastering the science of combustion through simulation, marine engineers ensure that the heart of the vessel beats with maximum efficiency and minimum environmental impact.
