New Generation of Turbochargers Announced
TCT turbochargers best overall package for two-stroke engines
MAN Diesel & Turbo has announced the development of a new turbocharger series specifically matched to the requirements of two stroke engines.
For the first time ever, MAN Diesel & Turbo will develop a turbocharger series
exclusively for two-stroke engines that is especially designed and optimised to fulfill
Tier III requirements. Compared to the TCA turbocharger range, successfully
introduced by the company during the last decade, TCT efficiency shows an increase
of 5% through using newly-developed compressor and turbine-wheel geometry,
consequently increasing waste-heat-recovery potential by 30%. The TCT range will
also deliver a 10% greater air flow at a turbocharging pressure 25% higher, while
being 30% smaller and 40% lighter than the existing TCA range. MAN Diesel & Turbo
reports that the first TCT turbocharger is expected to reach the market in 2016 after
an extensive validation and field-testing programme.
Dirk Balthasar, Head of Sales and Promotion – Turbocharger Business Unit – MAN
Diesel & Turbo, said: “Modern turbochargers must meet many demands, including
meeting technical requirements – such as Tier III compliance – at the most
competitive price, having small dimensions to facilitate installation in cramped spaces,
not to mention characteristics such as high operational reliability, low maintenance
frequencies and a long working life. The conflict of objectives is obvious.” He
concluded: “In developing the TCT range, it was important to MAN Diesel & Turbo to
balance the individual demands of the different groups of customers to achieve an
optimum overall result. Ultimately, we feel we have achieved this and believe the TCT
range to be the best overall turbocharger package for two-stroke engines.”
Advantages
MAN Diesel & Turbo reports that individual TCT turbochargers will cover a wider
range of engine ratings, and that engine manufacturers will be able to use just one
size for turbocharging different numbers of cylinders. It also states that individual
adaptation of the turbocharger to the engine will be by the established method of
using a variety of exchangeable parts within the turbocharger, while TCT production
costs can be controlled by dispensing with the alternatives required for four-stroke
engines. The requirement of Tier III engines – featuring EGR technology – for wide
compressor maps to cover different EGR flow rates will be met with the development
of specific compressor-wheel geometries with wide compressor maps.
The new TCT range provides shipowners and installation operators with significant
advantages. Customers familiar with the TCA ranges will find that TCT turbochargers
still provide them with proven solutions, such as the patented Super-Bolt compressor
wheel mounting that saves maintenance time. The life of expendable parts has also
been extended by using high-performance components, as reflected in lower servicing
frequencies. In line with established MAN maintenance philosophy, servicing can be
undertaken either by the operator itself or by MAN PrimeServ, MAN Diesel & Turbo’s
service division.
