The DL Series Doosan wheel loaders (DL200, DL250, DL300, DL400 and DL500) feature a common rail electronic engine that produces optimal horsepower and torque while meeting Tier III emission standards. The free-wheel stator in the torque converter on the DL400 and DL500, as well as the variable-displacement pump, improves power train efficiency to ensure optimum fuel economy. The variable-displacement piston pump and the Parker control valve produces higher working pressure and allows multifunction capability of the boom and bucket.
Features of the DL Series include communication between the engine and fully automatic transmission for smooth operation and traction in all working conditions; extended component life as a result of lower internal rpms; improved power train efficiency for optimum fuel economy; and a cab design that accommodates all operators.
