Diesel engines 10D100 of diesel locomotives 2TE10 are replaced by diesel engines 16ChN26/26 included in diesel-generators 1A-9DG (version 3). Ordinary operation of 56 sections of locomotive 2TE10 equipped with diesel-generators 1A-9DG (version 3) shows reduction of fuel consumption by 15,5% and oil consumption by a factor of 1,9 …2,8 as compared with diesel engines 10D100.Design solutions implemented in diesel-generator 1A-9DG (version 3) permit:
- reduction of maintenance and repair costs;
- improvement of economical parameters;
- extending of overhaul intervals.
Payback interval for locomotive reconditioning including installation of diesel-generator 1A-9DG (version 3) is no more than 5-6 years.Application examples
Installation of diesel-generators 1A-9DG (version 3) in locomotives 2TE10 during locomotive reconditioning is being carried out by Ussuriysky diesel locomotive repair plant. Diesel locomotives 2TE10 equipped with diesel-generators 1A-9DG (version 3) are operated in Severnaya, Oktyabr’skaya, Moskovskaya, Gor’kovskaya, Privolzhskaya and Dal’nevostochnaya railways as well as in Uzbekistan.Environmental compatibility
Diesel-generator 1A-9DG (version 3) has improved parameters (exhaust toxicity, smoke and sound pressure) complying with GOST.
