The 70,000-ton, shallow-draught tanker Stena President is powered by two MAN B&W 6S46MC-C engines. For comparison, one engine is fitted with a TCA55 turbocharger featuring the VTA adjustable vane nozzle ring and the other with the standard, fixed nozzle ring | |
| ||
|
After 10,000 operating hours in the TCA55-2V turbocharger with VTA technology, the bearing surfaces of both the adjustable nozzle ring vanes and their seats were still within their original works dimensional tolerances | |

|
VTA turbochargers from MAN Diesel & Turbo feature a nozzle ring with adjustable vanes. Seen here is the axial variant for the TCA axial turbocharger. The system is modular and occupies the same position as a fixed nozzle ring. It can be retrofitted to turbochargers already in the field | |

The MAN Diesel axial TCA55-2V turbocharger with VTA technology on a six cylinder, 46 cm bore MAN B&W type 6S46MC-C two stroke engine aboard the shallow draught tanker Stena President. The VTA turbocharger recently achieved 10,000 operating hours. A thorough inspection revealed excellent findings | |

Ideal technology in times of high fuel prices and tightening emissions legislation: in 2007, TCA and TCR turbochargers were equipped with VTA “Variable Turbine Area” control to allow the air quantity compressed by the compressor wheel to be precisely varied for optimised combustion. | |

Man Turbocharger 1940 – trendsetting from the first: MAN Diesel pioneered the use of inboard plain bearings to support the turbocharger rotor shaft. Today all manufacturers use this design; MAN Radial NR12 – in 1955 MAN Diesel began development of high-efficiency turbochargers with radial turbines. | |
