自从日立公司1931年制造第一台内燃机车以来,已制造出了大约300台电力传动内燃机车和1200台液力传动内燃机车以满足用户的需要。日立公司于1978和1979两年又为山区提供了两种具有 B_0-B_或 B_0-B_0-B_0轴式的、功率大、重量轻的电力传动内燃机车。在此期间,它还制造了三种新型标准内燃机车,该机车采用 ALCO 公司生产的中速柴油机并配备有半导体控制装置的无触点交流发电机,它引进大量的先进技术和吸收了多年的丰富经验。
Since Hitachi manufactured the first diesel locomotive in 1931, about 300 electric drive diesel locomotives and 1200 hydrostatic drive diesel engines have been manufactured to meet the needs of users. In 1978 and 1979, Hitachi also supplied two kinds of power-driven diesel locomotives with B_0-B_ or B_0-B_0-B_0-axis, large power and light weight for mountainous areas. In the meantime, it has also manufactured three new standard diesel locomotives that use ALCO’s medium-speed diesel engine and a contactless alternator equipped with a semiconductor control device. It introduces a large number of advanced technologies and has absorbed many years Experienced.
