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