Diesel-generator 5-26

For replacement of diesel engine 1440 (1223/30) whose service life has expired in diesel locomotives M62 diesel-generator 5-26 including diesel engine 1226/26 is used. The design of the diesel-generator allows to use the same auxiliary and electric equipment.

Installation of diesel-generators 5-26 featuring the latest design solutions in locomotives M62 allows to improve locomotive operational efficiency and to reduce:

Period of recovering locomotive modernization costs (including installation diesel-generator 5-26) is about 2,5 years.

Examples of application

Locomotives 62 equipped with diesel-generators 5-26 have been in service on Oktyabrskaya railway since 1996. Since 2002 diesel-generators 5-26 have been supplied to Belorussia and Mongolia, since 2003 to Lithuania. In 2006 supply of engines to Korean Democratic Republic started.

Diesel-generators are supplied complete with improved two-stage air cleaning system (with multi-cyclones and paper filters).

Environmental compatibility

Diesel-generator 5-26 has improved environmental impact as compared with diesel-generator 14 and complies with regulations 51250-99, 51249-99.
