Bauma China 2014—Dongfeng Cummins(I)

Bauma China 2014 will be host in Shanghai on November 25^th – 28^th, 2014, Dongfeng Cummins along with Cummins (China) investment Co., LTD will participate in exhibition on C72 booth in outdoor. Dongfeng Cummins will exhibit its tailored engine for excavator, loader and other construction machinery.

In Dongfeng Cummins booth, visitor can close feeling technical strength of DCEC engine, also can learn the Dongfeng Cummins leading-edge technology, swimming in the feast of science and technology.

In Dongfeng Cummins booth, you will feel:

Derived from classic

Mechanical Ⅲ stage products derived from Cummins industrial classical B and C series engine, keep more than 80% of the parts commonality, service, repair, maintenance are convenient.

Electric control Ⅲ stage products derived from Cummins construction QSB and QSL series engine, research and optimization of its key components by Cummins, proven by European and American markets, the quality is excellent.

Electric control Ⅲ products are ability to upgrade to the non-road emissions Ⅳ products.

Exclusive custom

According to the application characteristics of customer equipment, key optional features, expected optimize the engine performance curve, electric products can be matched best and ensure exclusive engine to customer.

According to the client different application and areas, electric engine can be set optimal curve to matching the local situation, protect economy and reliability of end user equipment.

According to the environmental and operation condition, electronic control system of Mechanical Ⅲ stage product can switch work mode intelligently, and also possess self-diagnosis, alarm and limp home function.

A variety of options

According to different flow direction, application field of equipment, choose different technical route, optimizing the allocation of resources, to keep product diversity.

Both the matching feature and meet customer needs, has a variety of choice, depend on customer.

More than 2.2 million sets of the engine, 1500 service station, supply above 1 billion Yuan of spare parts, to give customer choice.

At the same time, you can also have a close contact with DCEC engine, feeling its advanced science and technology:

B3.9/5.9

80～205HP（60～153KW）

China stage Ⅱ、Ⅲ emissions.

■Advanced design and excellent manufacturing, adapt to the harsh working conditions, have good capacity for high strength, heavy duty operation.

■Cylinder block, cylinder head adopts integrated design, to eliminate the phenomenon of leaking water and oil, parts about 40% less than other similar engines, greatly reduce the failure rate.

■Using forged steel camshaft and crankshaft, high strength of cylinder block design, many parts casting on the cylinder block, big stiffness, have good ability to resistance to high pressure, good reliability and long service life.

■Cylinder holes using cobweb honing design, perfect geometric structure prevent the leaking oil effectively, and adopt advanced technology such as the new type piston ring components and seal roll rim mould pressing, reduce oil wastage.

■Adopt Holset turbocharger with monolithic exhaust bypass valve, have good low speed response and dynamic property.

■According to the environmental and operation condition, electronic control system can switch work mode intelligently, and also possess self-diagnosis, alarm and limp home function.

QSZ13

380～575HP（286～500KW）

China stage Ⅲ、EU Stage ⅢA emissions.

■Adopt Cummins advanced XPI ultrahigh pressure fuel systems, pressure OF fuel injection up to 2400 bar. Through accurate combustion control, the minimum specific fuel consumption up to 186 g/kW.h, its low fuel consumption area is wide, much more fuel efficient.

■Excellent machine configuration, has a lighter weight and more compact structure in similar products, the maximum output power up to 500 kilowatts, it is energetic.

■Integral piston design with whole steel, cylinder block and crankshaft with high strength material, can bear the super detonation pressure of 2300 bar, harsh parts test, higher engine intensity, has excellent reliability.

■Adopt Cummins advanced electronic intelligent modules, monitor the engine running state at any time, precise control the fuel injection, to keep the engine also can reflect by itself.

■No need any cold start auxiliary device, start easily minus 15 ℃ ambient temperature; With auxiliary device can be started at minus 30 ℃.

■The engine adopts the optimized design of combustion chamber and high piston ring, advanced four valve structure, lower eddy ratio of cylinder head and air passage, high injection pressure fuel systems, smoke intensity is almost zero, to achieve the perfect combination of emissions and economy.

■Adopts advanced design, the engine maximum ratio of litre and power, up to 34.6 kw/L.

C8.3

145～260HP（108～194KW）

China Stage Ⅱ、Ⅲ emissions

■Advanced design, excellent manufacturing technique, reliable and durable, ability to operation of high strength, heavy duty under harsh conditions.

■Adopt super high pressure fuel pump, burning more fully under the high injection pressure, less energy loss, more powerful, fuel has well-adapted, lower emissions.

■Adopt Holset turbocharger with monolithic exhaust bypass valve, have good low speed response and dynamic property.

■Cylinder block adopts integrated design, parts about 25% less than other similar engines, greatly reduce the failure rate, maintenance more convenient.

■Cylinder liner using platform cobweb honing design and pistons adopt Ni-resist honing material, greatly reduce the loss of oil, enhance the durability, has longer service life.

■Advanced design, higher engine ratio of litre and power, up to 23.4 kw/L.

■According to the environmental and operation condition, electronic control system can switch work mode intelligently, and also possess self-diagnosis, alarm and limp home function.
