Sequential turbo charging (STC)
The new MAN Diesel & Turbo Sequential Turbo Charging System operates with high efficiency turbochargers. The benefit of this system is the option to switch the second turbocharger at low load operation off. This enables a low thermal signature, decreased smoke emission, low vibrations and reduced partload fuel consumption.
New turbocharger – TCA 33
Twin, high efficiency axial turbochargers have been specially developed for the V28/33D. These tuned axial turbocharger indicates low weight and compact design, provided for easier maintenance and have extended service life time. High efficiency at full and part loads results in substantial air surplus and thorough combustion without residues and low thermal stress of the combustion chamber components. Good part load operation due to very high turbocharger efficiency.
