Wärtsilä introduces latest addition to its RT-flex48T engine portfolio
(Thomson Reuters ONE) -
Wärtsilä Corporation, Trade & Technical press release, 1 December 2011
The new engine is designed to power small bulk and tanker vessels. The flex
common-rail technology lowers emissions and fuel consumption.
Wärtsilä, the marine industry's leading solutions provider, successfully started
up its new 6-cylinder Wärtsilä RT-flex48T engine on 24 November 2011 at the
facilities of Wärtsilä licensee QMD (Qingdao Qiyao Wärtsilä MHI Linshan Marine
Diesel Co Ltd.) in China. This new engine is the result of further development
of the existing Wärtsilä RTA48T engine. With the introduction of this new
engine, Wärtsilä completes its work in adapting its range of low-speed RT-flex
engines for all bore sizes. The engine type is also available in other cylinder
configurations.
The Wärtsilä RT-flex48T is designed to power small bulk and tanker vessels,
including the Handysize and Handymax range. With the implementation of the RT-
flex common-rail technology, the conventional and well-known RTA48T engine has
been upgraded to feature electronically controlled fuel injection, and exhaust
valve activation for greatly reduced emissions and fuel consumption. One great
advantage is its smokeless operation at all engine load levels.
"We are extremely pleased to add the Wärtsilä RT-flex48T engine to our portfolio
of common-rail low-speed engines. We now have this industry-leading technology
available for all bore sizes in our current low-speed engine portfolio," says Mr
Martin Wernli, President, Wärtsilä Switzerland and Vice President, Product
Centre 2-stroke.
The key features of the Wärtsilä RT-flex common-rail system are the precise
control of fuel injection, and the high injection pressure at all speeds which
together give steady running. The electronically controlled exhaust valve
opening/closing allows the best engine tuning for each individual engine rating.
To further develop the common rail version of the RTA48T engine, the rail unit
and supply unit were taken from the well-known and successful RT-flex50 type
engine. It consists of one common rail pipe for fuel injection and another
common rail pipe for the system oil driving the exhaust valves. Both are
integrated within the rail unit where all pipe works and components are easily
accessible from above. The rail unit is located just below the cylinder covers
along the complete engine length.
