This was validated by performing the measurement on an actual engine on an engine test bed, the company claimed.
As a performance yardstick for low-speed turbochargers, the industry applies the turbocharger efficiency benchmark given by MAN Diesel & Turbo (MDT).
The test took place earlier this year on a Hyundai test bed in South Korea. Three ABB A180-L turbochargers, produced by Hyundai under license, were fitted on an 8G95ME-C9.5 engine and the turbocharging efficiency was measured accordingly. The measurement was performed with wireless measuring equipment to ensure highest data accuracy.
For marine operations, the additional 2% efficiency increase achieved by the turbochargers would mean annual fuel savings of up to $35,000 per vessel, depending on fuel price and load profile. This efficiency increase was also confirmed and verified by MDT, ABB said.
Arie Smits, senior general manager, product group low-speed at ABB Turbocharging, said, “The result of the measurement on an actual engine is a confirmation of our promise and commitment to continue to push for highest efficiencies and value for our customers. Promised, delivered and proven.”
