8缸和12缸的Д49型柴油机目前已用在苏联的ТГМ6А、ТГМ8、ТЭМ2М、ТЭМ7和ТЭМ12型工矿和调车内燃机车上。用于ТГМ6А型工矿内燃机车上的8缸Д49型柴油机已经生产了1700多台,使用时间已超过8万小时。通过与苏联铁路上的其他同用途的17ПДГ-2、ПД1М、K6S310DR、211Д-3和MT53Б型柴油机相比,这种柴油机的燃油消耗率最低,比这一指标较好的ПД1М和K6S310DR 型柴油机还要低9～12％;临修次数为0.03件/千小时,名列前茅;比重量相当
The 8 and 12-cylinder Д49 diesel engines are currently used in the Soviet Union’s ТГМ6А, ТГМ8, ТЭМ2М, ТЭМ7 and ТЭМ12 mining and shunting diesel locomotives. For ТГМ6А industrial and mining diesel locomotive Д49-type diesel engine has produced more than 1,700 units, the use of time has more than 80,000 hours. This diesel engine has the lowest fuel consumption rate compared with the other 17ПДГ-2, ПД1М, K6S310DR, 211Д-3 and MT53Б diesel engines on the Soviet railway, and the engines of the ПД1М and K6S310DR diesel engines which are better than this indicator Lower 9 to 12%; temporary repair times of 0.03 pieces / thousand hours, among the best; the same weight
