Diesel-generator 3-26

For replacement of diesel engines 3-9 2 whose service life has expired in diesel locomotives 114 (the locomotives are in service in tropic conditions) Kolomensky Zavod is developing 4-cycle 12-cylinder diesel engine based on the engine family 49.

Installation of diesel-generator 3-26 in locomotives 114 will permit to provide improvement of technical and economic parameters of the locomotive, reduction of load axle as well as harmful emissions, smoke, maintenance and repair costs, increase of overhaul intervals.

Examples of application

Project Environmental compatibility

Use of diesel-generator 3-26 in locomotives 114 permitted to considerably reduce harmful emissions, smoke and sound pressure.
