DF8B diesel locomotive, as the mainline freight diesel locomotive with the highest power for single diesel engine in China, is the ideal traction power for speedup of heavy mainline freight transportation. Equipped with 16V280ZJA diesel engine, JF204D synchronous main alternator and ZD109C traction motor, the locomotive has speed of more than 90km/h at maximum constant power. It was awarded “Second Prize of MOR Scientific & Technological Progress” and Jiangsu Province Excellent New Product “Golden Ox Prize”.
New technologies such as microcomputer control system, large-screen color liquid crystal display, dynamic brake unit for self-load test at full power and etc., are utilized in this locomotive. It is modern in electric control technology and excellent in dynamic performance.
DF8B diesel locomotive is widely used in state railway and industrial and mining companies, this locomotive is designed by taking DF8B diesel locomotive as prototype. It has been exported to Venezuela, Iran, Guinea and so on.
