ТЭ3型内燃机车运用中,起动时牵引发电机经常出现大电流冲击现象,即内燃机车猛冲起动。当其速度提高到25～30km/h时,就出现冒黑烟。柴机油的转速不提高(喷油泵齿条在控制器9～10位的止挡上),其功率不会超过850～900kW。随着内燃机车速度提高到30～35km/h以上时,柴油机的转速就逐步增加;功率提高到16位时的1100～1200kW,排气变为正常的颜色。所有这些都表明,牵引
In the use of ТЭ3 diesel locomotive, the traction generator often has a large current impact phenomenon at start-up, that is, the start-up of a diesel locomotive. When its speed increased to 25 ~ 30km / h, appeared black smoke. Diesel engine speed does not increase (injection pump rack in the controller 9 to 10 stops), its power will not exceed 850 ~ 900kW. As the speed of diesel locomotive increases to more than 30-35km / h, the speed of the diesel engine will gradually increase. When the power is increased to 1100-1200kW at 16, the exhaust gas will become normal color. All of this shows that traction
