Diesel-generator 5-26ДГ

For replacement of diesel engine 14Д40 (12ДН23/30) whose service life has expired in diesel locomotives M62 diesel-generator 5-26ДГ including diesel engine 12ЧН26/26 is used. The design of the diesel-generator allows to use the same auxiliary and electric equipment.

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

• maintenance and repair costs;
• fuel consumption up to 20%;
• fuel consumption at idling by a factor of ~ в 1,8;
• oil consumption by a factor of ~ в 1,5.

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

Examples of application

Locomotives М62 equipped with diesel-generators 5-26ДГ have been in service on Oktyabr’skaya railway since 1996. Since 2002 года diesel-generators 5-26ДГ have been supplied to Belorussia and Mongolia, since 2003 – to Lithuania. In 2006 году 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 5-26ДГ has improved environmental impact as compared with diesel-generator 14ДГ and complies with regulations Р51250-99, Р51249-99.
