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 Diesel Engine Co., Ltd. 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.
