121 Serial Diesel Engine, manufactured under world leading technology - 3300 Series product, is elaborately tailor-made to engineering machinery with a global   possession number of over 1,000,000 and continuously supported by World   leading in technology. Besides, Shanghai New Power Automotive Technology Company Limited.   introduces World leading's main component processing equipment and   product test equipment, adopts America's advanced technology and pays   special attention to component reliability in design and manufacture,   thus making 121 Diesel Engine known as a generally accepted trump power   of engineering machinery for its high quality and reliability.
High Reliability
The exquisite design of the parts and the entire machine   follows the design conception of high reliability and long durability,   and the sameness of durability between the main parts and the entire   machine. The important friction pairs are much reliable and durable.   According to the statistics of actual auxiliary application, equipped   with a Shovel Loader or dozer, it has a general average breakdown   interval of over 4,000h and an overhaul period of over 10,000h. Under   severe environmental condition, D7G (160kW/2,000r/min) Crawler Dozer has   an average breakdown interval of over 4,167h and an average overhaul   period of over 11,500h. 
Strong Power
         121 Serial Diesel Engine has a power displacement of 10.45L,   larger than its competitors, and a coefficient of torque reserve, as   high as 1.5. Besides, it is easy to operate with supernormal dynamic   performance and good responsivity 
High Efficiency
         In comparison with its competitors, 121 Serial Diesel Engine   is 23% higher in efficiency and 10% lower in fuel consumption rate of   unit work amount (more, faster, better and cheaper).
Strong Adaptive Capacity to Plateau
         The power of the diesel engine is not prone to loss on a plateau at altitude of 4,500m.
  Easy Maintenance and Simple Repair 
  Adequate Reserve of Parts
         All parts are homemade with a reasonable price of part repair and are available nationwide for convenient purchase.
