- Our team focused on raw files with an RPM of 80 for analysis.
Discovery/Insights from Our System
- For the Doosan-Sulzer 12-cylinder 2-stroke engine, our Engine Condition Monitoring System found that although the overall health parameters at 80 RPM were satisfactory, there was slight deterioration as shown by the mechanical health indicator.
- On further investigation, we identified that when the damper gets fully excited at about 80 rpm, it adds a non-linear delay (twist) to the crankshaft.
- This leads to a change in fuel injection timing, causing a small imbalance in the combustion conditions of a few cylinders.
- As a result, the fuel efficiency decreased by over 1.2%.
- Taking the damper’s delay into consideration while changing valve setting and fuel regulation timing could lead to over 1% in fuel consumption savings, which is to the tune of 400 to 500 tonnes of fuel per year for an engine this size.
