Diesel engine 7-6Д49

Modern 4-cycle 8-cylinder diesel engine 7-6Д49 (26/26) is intended for replacement of engines 3АЭ-6Д49 whose service life has expired in shunting and industrial locomotives ТГМ8 and ТГМ6 operated in climatic conditions Т2.

With the main locomotive parameters being the same (power, design speed and и tangential traction force) considerable improvement has been achieved in:

• fuel and oil consumption;
• harmful emissions;
• smoke ;
• overhaul intervals and maintenance costs.

Examples of application

Locomotives ТГМ6 equipped with diesel engines 7-6Д49 are in service on Russian railways, at industrial enterprises of the Russian Federation and CIS.

Replacement of the engine can be carried out directly on site as special complicated equipment and highly qualified personnel are not required to do the job.

Environmental compatibility

Installation of diesel engines 7-6Д49 in locomotives ТГМ8, ТГМ6 provided considerable reduction of harmful emissions, sound pressure and smoke.
