意大利国家铁路接收了装用直流发电机的D345型和装用交流发电机的 D445型干线电传动内燃机车,完成了长期以来的购置计划。意大利机车制造业在发展标准型内燃机车方面是卓有成效的。带有单电机转向架的 D343/D443型系列机车也是其中一例。D445型内燃机车的特点体现在三相交流发电机上,它通过变流器换流,最后以直流牵引电动机工作。机车采用菲亚特公司生产的带增压空气冷却的12缸四冲程增压柴油机作为动力机组。这台柴油机同功率为1490千瓦的交流
The Italian National Railroad received the D345 model with a DC generator and the D445 mainline electrically driven diesel locomotive with an alternator, completing a long-term acquisition plan. The Italian locomotive manufacturing sector has been fruitful in the development of standard diesel locomotives. One example is the D343 / D443 series locomotive with a single-motor bogie. D445 diesel locomotive features reflected in the three-phase AC generator, which commutates through the converter, and finally to the DC traction motor. The locomotive uses a 12-cylinder four-stroke turbocharged diesel engine produced by Fiat with charge air cooling as a power unit. This diesel engine with the same power of 1490 kilowatts of exchange
