MAN’s VTA technology improves turbocharger performance

MAN Energy Solutions’ Variable Turbine Area (VTA) technology, which enables charge air volumes to be matched precisely to the quantity of fuel injected at all points in an engine’s load and speed range, is now standard on the company’s large-bore, four-stroke engines.

Turbochargers with VTA systems on engines in the MAN 51/60DF range mean that the company is the only turbocharger manufacturer to offer axial turbochargers with VTA as standard for any engines in the large-bore, four-stroke segment.
The company claims that VTA systems typically pay back in 18 to 24 months and have a range of benefits including significant fuel savings and operational flexibility, improved dynamic performance and a better response to load fluctuations.  
MAN is now planning to make VTA systems standard on its 51/60G gas engine types and has introduced new VTA-specific training courses at its PrimeServ Academy.
