Chongqing Cummins QSN and K50 high horsepower engine new products unveiled BMW China show
At the Cummins booth of the Shanghai 2010 International Construction Machinery Exhibition, an all-electrically-operated 14-liter QSN engine attracted attention. This is a new engine developed by Chongqing Cummins in 2010 and has independent intellectual property rights. It uses Cummins advanced technology. The CELECT electronic control system can fully meet the requirements of GB20891-2007 China National Standards for non-road mobile equipment at different stages of emission levels, and meet the third and later stages of European and North American off-road emission standards (Tier3) requirements.
The main advantage of the epc
1. The shape of casting size precision, good repeatability, has the characteristics of precision casting;
2. The casting surface finish high;
3. Cancel the sand core and core xiaohong, eliminated due to core, the core of casting defects and waste;
4. Out of box, not modulus, greatly simplifying the molding process, to eliminate the casting defects caused by modulus, tanks and waste;
5. The binder, water, dry sand molding without any additives, eliminated due to moisture, additives and binder caused by all kinds of casting defects and waste;
6. Greatly simplifies the sand processing system, the sand can be repeated use, all cancelled &industry sand preparation and waste sand treating section;
7. Shakeout extremely easy, greatly reduces the shakeout workload and labor intensity;
8. Castings without flash burr, make clear the burnish workload by more than 50%;
9. Can be set up in an ideal position reasonable shape of the riser, is not subject to classification, the restriction of traditional factors such as modulus, reduce the internal defects of casting;
10. Negative pressure casting, is more advantageous to the liquid metal filling and feeding, improved the casting organization density;
11. A combination of pouring, a box, greatly improving the casting craft production rate and production efficiency;
12. Reduce the machining allowance, reduces the machining cost;
13. Automatic assembly line production, easy to realize mechanization production line elasticity, can implement different alloy on a production line, different shape, different size of casting production.
14. You can cancel the draft Angle;
15. The use of metal die life can reach more than 100000 times, reduce the mold maintenance;
16. Reduced the dust, smoke, and noise pollution, greatly improved the working environment of foundry workers, reduce the pain
Dynamic strength, mainly men can become predominantly female industry;
17. Simplified the process operation, on the degree of skilled workers required is greatly reduced;
18. The shape of the parts is not restricted by the traditional casting process, the liberation of the mechanical design workers, to make it according to the using performance of the parts, free to design the ideal shape casting;
19. Can reduce the casting weight;
Reducing the production cost; 20.
21. Simplified the factory design, can reduce 30 ∽ 40% of investment in fixed assets, covers an area of area and construction area
30 ∽ 50%, reduce power consumption can reduce 20%; 10 ∽
22. The epc technology widely used, not only suitable for cast steel, cast iron, more suitable for cast copper, cast aluminum, etc.;
23. The Epc Casting process is not only suitable for simple geometry, more suitable for ordinary casting to attack rolled edge, core, geometric shape of complex castings;
24. The Lost Foam Casting process can realize microtremor state pouring, promote the formation of the special requirements of metallographic organization, to improve the inner quality of casting;
25. Combined on the dry sand casting, easy to take off the sand, temperature, therefore can make use of waste heat to heat
Richard.Especially high manganese steel castings water edge processing and heat resistant steel solid solution treatment, the effect is very ideal, can save a lot of energy, shorten the processing cycle;
26. The use of epc process, can according to melting ability, complete any size castings.

Another engine exhibited by Chongqing Cummins is the 50-liter K50 engine, which is one of the lowest-maintenance, most durable engines in the world's high-powered engine family. It is also Cummins's most powerful engine for local production in China. The mature technology and reliable quality K50 engine is now widely used in mining equipment, drilling equipment, ship power, track equipment, port equipment, construction machinery, generator sets and other equipment. At present, the domestic market is in great demand. Chongqing Cummins has been gradually increasing the production and sales of K50 engines since 2010 to meet the needs of users.
In 2009, it was the most difficult year for Chongqing Cummins to develop. Due to the impact of the global financial turmoil, the situation in which the company’s products were in short supply has changed dramatically. The demand for products in key markets has been greatly reduced, and users’ requirements for product quality and delivery time have been greatly reduced. More stringent, but also facing foreign brands to compete in the domestic market competition, the introduction of new products, becoming the main direction of change in Chongqing Cummins in 2010. Chongqing Cummins, on the basis of careful digestion and absorption of Cummins engine technology, produces high-quality diesel QSN electronically controlled engines adapted to the Chinese market. Its emissions have reached the third stage emission standards for off-highway diesel engines, and its performance has been greatly improved, thus prolonging. The life cycle of the original NT855 series engine has made its dominant position in the domestic construction machinery market more stable.
