pioneer of global emission technology

Cummins, as the world's largest independent diesel engine manufacturer, produces and sells diesel and natural gas engines with a wide range of power and corresponding parts and components for automotive, industrial and power generation equipment and other fields. Cummins engine has a displacement of 1.4~95 liters and a power range of 31 to 5000 horsepower. It is widely used in various road vehicles such as trucks, buses, recreational vehicles and commercial vehicles, as well as non highway fields such as construction machinery, mining equipment, agricultural machinery, ships and railways. Cummins engine is not only famous in the industry for its first-class reliability, durability and fuel economy, but also has been in the leading position in the industry in meeting the increasingly stringent automotive emissions (U.S. EPA 2013, Euro V and euro VI standards), off highway motor equipment emissions (tier4interim/stageiib standards) and marine aircraft emissions (IMO standards), The company always adheres to the mission of "creating a cleaner, healthier and safer environment"

as a leading enterprise in the global engine industry, technology R & D advantage is a key part of the company's global core competitiveness. In 1968, Cummins took the lead in all diesel engine manufacturers and invested 23million US dollars to officially establish its first large-scale technology research and development center in Columbus, Indiana, where the company's headquarters is located, which laid a solid foundation for the company to meet the challenge of increasingly stringent environmental emission regulations since the early 1970s, and also established Cummins' leading position in the field of diesel engine technology research and development. After that, Cummins has successively established 19 R & D institutions in the United States, Mexico, Britain, France, India, Japan, Brazil and China, and established a strong global R & D network, with a total of more than 300 testing laboratories and more than 4000 R & D engineers and technicians, of which more than 40% are outside the United States, especially in China and India. In the past 20 years, Cummins has invested a total of more than $6billion to develop a new engine technology platform, with an average daily investment of more than $1million. More than 80% of the funds have been spent on efforts to reduce the emission of harmful substances and greenhouse gases classified by the film friction coefficient measurement method of the engine, so as to meet the increasingly stringent global exhaust emission standards. In 2012, Cummins' R & D investment in that year alone exceeded US $720million, accounting for more than 4% of sales

Cummins' clean in cylinder combustion technology, ultra-high pressure fuel technology, efficient supercharging technology, advanced post-treatment technology, reliable filtration technology, and system control integration technology with high integration function form the unique advantages of Cummins's environmental protection engine, which is also a necessary condition for greatly reducing engine emissions and improving fuel efficiency. Cummins became the first company in North America to launch the environmental protection standard of EPA 2002 by using cooled exhaust gas recirculation (EGR) technology, 15 months ahead of the original regulation time; Using selective catalytic reduction (SCR) post-treatment technology, Cummins is also the first batch of engine manufacturers to meet Euro IV and Euro V emission standards. Aiming at the most stringent environmental protection regulation in the world today - the environmental protection standard of EPA 2013 in the United States, Cummins has once again become the first engine enterprise to meet the standard through the optimized combination of particulate filter (DPF) and SCR technology, and further saves fuel consumption for users

Cummins has a history of focusing on engine technology for nearly 100 years. As the first batch of international power manufacturers rooted in China, Cummins has also gone through the process of manufacturing diesel and natural gas engines in China for more than 30 years. The company's institutions at all levels in more than 100 countries around the world produce and sell nearly one million diesel and natural gas engines every year, which makes Cummins more deeply feel the heavy responsibility of reducing emissions

take the lead in introducing the most advanced emission technology into China

as the world's leading power equipment supplier, Cummins continues to develop advanced power products to meet and lead the increasingly stringent global requirements for engine exhaust emissions and noise standards while improving fuel economy. Cummins has long insisted on working with its Chinese partners to introduce the most advanced environmentally friendly engines into the Chinese market. The company has always been committed to providing the most advanced low emission and environmental protection products to our customers at the same time with the international market, and customizing innovative low emission and high-efficiency solutions for our Chinese users. Cummins is the first diesel engine manufacturer to introduce Euro II, Euro III, Euro IV, Euro V and hybrid engines into China. Cummins has also been actively exploring the application of clean fuels and the optimal combination of traditional energy and new energy, and is a pioneer in many fields, such as natural gas products, hybrid power and biodiesel applications

as early as 1996, Dongfeng Cummins, a joint venture of Cummins, introduced Euro I engines at the beginning of its establishment, but at that time, the emission standard of domestic engines had not yet taken shape. In 2000, Cummins first introduced diesel engines that meet the requirements of Euro II emission perfect mandatory standard system into the Chinese market. Since 2001, Cummins has been ahead of the industry, taking the lead in launching a full range of ultra-low emission vehicle engines to the European, American and Chinese markets simultaneously, meeting the Euro III environmental protection standards. At that time, the domestic emission regulations only required the full implementation of Euro II emissions by 2005. In 2002, Cummins' 5.9-liter Euro III electronically controlled diesel engine successfully matched the 18 meter "Big Mac" front articulated bus of Beijing bus for the first time, and achieved batch application. It was not until December 30, 2005 that Beijing began to fully implement the national three emission standards. That year, Cummins took the lead in promoting the Euro IV fully electronic controlled engine in the Chinese market with international synchronization. In 2006, Cummins has achieved batch matching of Euro IV vehicles in China. In 2008, Beijing buses equipped with Cummins Euro IV and Euro V low emission electronically controlled diesel engines and natural gas engines served as the main passenger service during the Beijing Olympic Games. In 2010, Cummins and its Chinese customers officially launched the research and development of Euro VI. At this time, in addition to the national four standards implemented in Beijing, the national three emission standards are still implemented. The long-term haze weather in Beijing from the end of 2012 to the beginning of 2013 accelerated the pace of implementing the national V emission standard in Beijing. With the approval of the State Council, Beijing took the lead in implementing the Beijing phase V motor vehicle emission standard equivalent to the national V standard since February 1, 2013. The oil products matching this emission standard were also listed on May 31, 2012. From July 1, 2013, the national four standards for commercial vehicles have been officially implemented. While taking the lead in introducing advanced emission standards, Cummins has also been supporting the improvement of environmental protection technology of other local engine and vehicle enterprises in China, making every effort to realize localized production, and gradually driving the emission upgrading of the whole industry and the improvement of regulations

cooperate with the whole industrial chain to meet the national four new standards

on July 1, 2013, the national four emission standards for diesel will begin. At that time, all compression ignition engines and vehicles for vehicles produced, imported, sold and registered must meet the national four standards. This requires all engine and vehicle manufacturers to upgrade their technology and create a new platform that meets the fourth national standard. At this time, Cummins has completed the corresponding layout preparation through years of unremitting efforts and cooperation with domestic OEMs

in terms of production, Cummins and Foton automobile jointly established Foton Cummins Engine Co., Ltd. in 2009. At the beginning of its establishment, it assembled a production platform that can produce Euro IV and above standard engines; At the same time, Xi'an Cummins, a joint venture between Cummins and Shaanxi Automobile, launched the first batch of heavy-duty diesel engines that meet the emission requirements of the fourth national standard; In addition, Dongfeng Cummins, a joint venture between Cummins and Dongfeng, has also upgraded its production line to meet the requirements of the four standard engine of the country. At present, Cummins can achieve an annual output of more than 700000 national standard engines in China

in terms of products, please replace the experimental materials if it exceeds the limit. Cummins's national Fourth Highway engine products produced in China range from 2.8 liters to 13 liters, covering the light to medium and heavy commercial vehicle market. Together with supplementary imported models, they can fully meet the needs of the domestic national Fourth Market. In addition, Cummins has cooperated with domestic OEMs to obtain relatively homogeneous upper and lower yield points, maximum force points, various specified non proportional stress points, various specified full elongation stress points, etc; At the same time, it meets the pressure test requirements of the experimental machine; The national four product announcement can produce and sell mature products at the first time to meet customer requirements

in terms of service, Cummins has always been committed to the training of engine maintenance and repair of the fourth country. At present, Cummins has set up 34 product service platforms in China, with more than 2000 wholly-owned and joint venture distribution service stations, and regularly trains the engineers of the service platforms and service stations to make them adapt to the characteristics of the fourth country products faster. It can be said that the whole vehicle equipped with Cummins country 4 engine will not only not be discounted in service, but also have a better experience

characteristics and advantages of the fourth national technology

compared with the third national emission standard, the fourth national standard requires that the engine's particulate emissions be reduced by 80%, nitrogen oxide emissions by 30%, and carbon monoxide and hydrocarbons are also greatly reduced. Cummins' four products have two technical routes: SCR (selective catalytic reduction) and egr+doc (exhaust gas recirculation + oxidation catalyst). These two routes have been widely used in North American and European markets, and their progressiveness and applicability have been fully verified. Compared with the products of the third national standard, the products of the fourth national standard can bring more long-term value to users. First of all, it has a wide range of oil adaptability, which can be applied to the differences of oil products in different regions in China, improving the distance of vehicle transportation and reducing the maintenance cost; Secondly, the fuel economy is further improved compared with the national three-level engine, saving users more operating costs. Due to the reduction of carbon particle emissions deposition, the service cycle interval is correspondingly extended, and the maintenance cost is reduced, which ultimately directly benefits end customers

green energy-saving system -- EBP smart people

while constantly striving to reduce exhaust emissions pollution, Cummins has also created a set of "EBP smart people" system that can be adjusted according to real-time road conditions, drivers' driving habits and the state of the engine itself through its own technology research and development. In China, since 2011, Cummins has cooperated with key OEMs to significantly reduce the fuel consumption of vehicles using Cummins engines by adopting the "EBP smart man" systematic energy-saving project. Through simple button selection, the "interactive communication" between engine, vehicle and driver can be realized, and good driving habits can be actively guided. The driver can flexibly select the power, standard and economic gear selection keys according to different road conditions such as national highways, plains and hills, mountain roads and ramps, as well as different loading conditions such as heavy load, standard load and light load. Cummins makes use of the rich electronic control function of its engine
