8GDG, 8 GDG -N
Gas/diesel-generators 8GDG, 8GDG-N rated 1650 kW and created on the basis of diesel engines ChN26/26 are intended for generating electric and thermal power in power stations of all types, providing consumers with electric (3-phase a.c.) and thermal energy.
The main fuel is diesel fuel or rude oil. Using natural or associate gas is also permitted with pilot fuel (diesel fuel or rude oil) amounting to 12%-15%.
Power plants may be supplied as stationary or transportable modular plants.

Design features
- versatility and safety (automatic transfer to diesel mode when interruptions in gas supply occur or gas leakage detector is triggered );
- easy access during overhaul (major overhaul included), without removal from engine room;
- low cost of maintenance and oil used;
- reliability and wear resistance of parts and assembly units;
- modular engine design, providing high operation and overhaul efficiency;
- parts standardization (80%);
- optimal consumption of domestic fuel and oil;
- long overhaul intervals and low maintenance;
- cylinder block of dry type (no contact with cooling water and, as a result, no corrosion);
- smoke, harmful emissions and noise comply with Russian and European standards.
Total running time of multi-fuel power plants produced by PJSC “Kolomensky Zavod” is over 1 million hours.
