Д49

PJSC «Kolomensky Zavod” is a designer and a leading producer of modern 4-stroke medium-speed turbocharged intercooled engines of type Д49 (ЧН26/26). Diesel engines ЧН26/26 have 8, 12 or 16 cylinders in V-version.

Depending on the engine speed (750 ... 1100 rpm), the number of cylinders and brake mean effective pressure the engines are rated from 588 to 4412 kW. The main application of engines ЧН26/26 is for railway transport of Russia. The engines are also used in CIS, Baltic countries, Germany, Bulgaria, France, Mongolia, Syria, Pakistan, Cuba and others. They are widely used as main and auxiliary propulsion plants for civil and military ships, emergency sources of power supply as well as power plants for heavy-duty dump trucks, mobile and stationary power stations for extraction and exploration purposes on land and sea, for PJSC “Gasprom” included (see section “Power Stations and Self-contained Power Equipment”).

Over 14000 diesel engines of this type have been produced since full-scale production started. Over 30% of these have been exported. Long-term programs of diesel engine development adopted by Transmashholding in cooperation with PJSC “Russian Railways”, the Navy of the Russian Federation, the Ministry of Nuclear Energy and foreign companies allow Kolomensky Zavod to realize investment projects aimed at renovation of the production basis and R & D efforts with a view to improve technical and economic characteristics of the diesel engines.

In 2005—2006 Kolomensky Zavod developed and produced a unique marine diesel-diesel aggregate ДДА 12000 for the Navy of the Russian Federation. Two diesel-diesel aggregates ДДА12000 rated 24000 hp were included in the main propulsion plant of the type corvette “Stereguschiy” of the latest generation. Diesel-diesel aggregate ДДА 12000 is intended for driving fixed-pitch propeller and includes 2 modern diesel engines 16D49 rated 6000 hp each. It also includes 2-speed reduction gear with noise isolating coupling providing combined and separate operation of diesel engines, local microprocessor-based control and protection system.

The microprocessor-based control system permits to adjust engine load, to provide reverse operation modes and to shut off one of the engines if necessary.

Kolomensky Zavod takes an active part in the process of revival of the Russian fleet. Diesel engines Д49 are being installed in submarines "Lada" and "Amur" – the most advanced projects of the XXI century.
