Type GKD3B diesel locomotive is a new type of economic and environmental protection shunting and transfer locomotive which is provided for all the users in and out of railway. Its wheel arrangement is Co-Co, axle load is 23t or 25t and max. speed is 100k

In the locomotive is installed a type 12V240ZJ diesel engine rated at 2000kW in vehicle. There are electronic injection and mechanical injection methods for users to choose. When adopt the electronic injection, the diesel engine cancel the velometer, the speed becomes more stable, and the inertia speed can be adjusted from 400r/min to 350r/min, so finally reduce the oil consumption with no-load service. The pressure charging system adopt pulse pressure charging, so the diesel engine has a good following performance. It is very useful to the shunting, because most of shunting locomotives under low-load service can achieve good economic efficiency and emission performance. The locomotive adopts the programmed control and adds a logical control and color LCD screen display. The microcomputer control is more perfect, compared with the shunting locomotive made before, the content is more, the range is wider, operation is more reliable.

The main generator adopts brushless excitation, cancels the exciter and rectifier, so the main generator become more advanced and reliable.
