MAN Energy Solutions has added variable turbine area (VTA) technology to its TCA turbochargers for the MAN 51/60 engine type, marking the first time that VTA technology has been approved as standard for a large-bore MAN four-stroke engine.
Stefan Terbeck, project manager for the MAN 51/60 engine series, said, “VTA turbochargers are becoming more and more important, especially when it comes to gas engines. VTA has already been applied from our licensee at Kawasaki Heavy Industries, who has reported excellent performance and high reliability on their engines.”
Under the VTA concept, the volume of charge air can be precisely matched to the quantity of injected fuel at all points in an engine’s load and speed range. The benefits of this include significant fuel savings and greater dynamic performance.
“We collected more than seven years of operational experience before approving VTA technology as standard,” added Terbeck. “As a result, our 51/60DF engine is getting a proven, field-tested product.”
