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.
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.
