4-36DG

4-36DG

Diesel engine 8ChN26/26 included in diesel-generator 4-36DG was developed to replace obsolete Czech diesel engine К6S310 in shunting locomotive CHME3.

Installation of diesel-generator 4-36 DG in locomotive CHME3 permitted:
  • to reduce fuel consumption by 10%;
  • to reduce oil consumption by a factor of 2,8;
  • to double major overhaul interval;
  • to increase top end overhaul interval by a factor of 2,5.
Application examples

The first locomotive with diesel-generator 4-36DG has been in operation at depot Pechory since 1999. A batch of diesel-generators 4-36DG intended for installation in locomotives CHME3 was supplied to Uzbekistan. Diesel-generators 4-36DG continue to be supplied to Russian Railways.

Environmental compatibility

Installation of diesel-generator 4-36DG in locomotives CHME3 permitted to considerably improve ecological parameters (exhaust toxicity, smoke and sound pressure).
