DF11G double-heading quasi-high speed passenger diesel locomotive
is specially developed for the 5th great speed-acceleration of
railway. It is equipped with 16V280ZJA diesel engine, JF204D
synchronous alternator, ZD106E traction motor, imported
MTU12V183TB12G auxiliary diesel engine for power supply and
LSA47.1L11-4P generator. High traction power: Service power of diesel engine 2×3610kW,
residual acceleration still remains 0.0245m/s2 when hauling 20
passenger cars at the speed of 160 km/h. Function of power supply to passenger car: Equipped with auxiliary
diesel generator set with the Max. power supply 2×400kW, supply
system AC380V. Advanced technology: Microcomputer Lonworks network control new
technology is applied, which has complete logic control for
locomotive, train communication network technology, perfect
breakdown diagnosis function and remote monitoring & diagnosis. Perfection and reliability: It is based on reliable and advanced
technology of DF11、DF11Z locomotive, and critical parts are
imported. Good adaptability: Bearing type fuel tank with large capacity,
fire-alarm and fire extinguishing equipment, as well as service
switches setting in the cab are employed in order to adapt to extra
long louting and single operator. State-of-the-art design and manufacture: Absorb and draw on all the
achievements of upgrading manufacture level, and improve the design
and manufacture level in all aspects. Streamline car body and
standardized pipe layout are adopted. | Performance Parameters: | | | Purpose | Quasi-high speed passenger transportation on artery | | Gauge | 1435mm | | Axle arrangement | 2Co-Co | | Wheel diameter | 1050mm | | Axle load | 23t | | Service weight | 2×138t | | Max. operation power of diesel engine | 2×3610kW | | Nominal power | 2×3040kWTransmission ratio of traction gear 76/29 | | Locomotive speed | a Max. operation speed170km/h half wear out of driving tire | | b Continuous speed83.5km/h half wear out of driving tire
