The first generation DF8 was powered by the original 3310 kW 16V280ZJ engine.
The second generation DF8, the DF8B, is powered by an updated 16V280ZJA engine with 3680 kW. Production started in 1997 and lasts until today. Qishuyan, Dalian and Ziyang manufacture 0, 3000 and 5000 series of DF8B respectively.
12 DF8Bs were exported to Venezuela and are called DF8Bven, however they are identical to the domestically used DF8B. [1]
Ziyang made a special DF8B which was originally intended to be used on the Qingzang line and was numbered DF8DJ-0001. The special model is powered by a Caterpillar 3516 engine (6,500 hp) and six AC traction motors. The Chinese Ministry of Railways rejected the proposal and it was renamed DF8B-5672. It's now running on Xiyan Line in Shaanxi.
The DF8BJ, which uses the 16V280ZJG engine (4,000 kW), GTO VVVF inverter and AC traction motors, is produced by Ziyang [2]. It was designed for Qingzang Railway. Before arrival of GE locomotives for Qingzang, it was named NJ2.
The DF8CJ version is produced by CSR and has a 16V280ZJB engine (maximum power 4.4MW) and AC inverter traction drive.[1]
The DF8DJ version has a CAT 3616 engine of rated power 4.8MW and AC asynchronous traction motors.[2]
The original DF8 was manufactured in Qishuyan by CSR Qishuyan Locomotive and Rollingstock Co.,Ltd., the DF8B is also manufactured in Qishuyan by CSR Qishuyan Locomotive and Rollingstock Co.,Ltd. and in Ziyang by CSR Ziyang Locomotive Works.
