Diesel-generator 1А-9ДГ (version 3)

Based on the family of unified diesel engines Д49 diesel engine 16ЧН26/26 has been developed and is produced for use as a component of diesel-generator 1А-9ДГ (version 3) intended for replacement of power plants including obsolete 2-cycle diesel engines 10Д100 installed in diesel locomotives 2ТЭ10.

Operation of 56 locomotive sections (of type 2ТЭ10) equipped with diesel-generators 1А-9ДГ (version 3) showed reduction of fuel consumption by 15,5% and of oil by a factor 1,9 to 2,8. Design solutions implemented in the diesel-generator 1А-9ДГ (version 3) allowed to provide compliance with modern requirements for harmful mission limits, smoke and sound pressure and to reduce maintenance and repair costs, to improve economical parameters and to increase overhaul intervals.

Period of recovering costs for major overhaul/reconditioning including installation of 1А-9ДГ (version 3) covers from 5 to 6 years maximum.

Examples of application

Installation of diesel-generators 1А-9ДГ (version 3) in locomotives of type 2ТЭ10 during major overhaul/reconditioning is carried out by Ussuriysk Locomotive repair Plant. Locomotives 2ТЭ10 equipped with diesel-generators 1А-9ДГ (version 3) are in service on Severnaya, Oktyabr’skaya, Moscovskaya, Gor’kovskaya, Pryvolzhskaya, Dal’nevostochnaya railways (Russia) and in Uzbekistan.

Environmental compatibility

Diesel-generator 1А-9ДГ (version 3) shows reduced smoke, harmful emissions and sound pressure complying with GОSТ Р51249-99, GОSТ Р51250-99.
