Cummins ISF is expected to become the main driver of the light-duty diesel vehicle IV market
The haze weather sounded the alarm for the people's environmental awareness, the motor vehicle emission standards were focused on the lock, and the diesel car was once again pushed to the cusp. The twists and turns of the implementation of the National IV emission standard looks more like an environmental protracted war. On July 1, 2013, it was a clear and loud assembly. The implementation of the National IV emission standard has almost become a "stubborn" fact, but July 1 does not seem to be a full stop but a question mark or an ellipsis. As the national IV emission standard is a key link, what is the preparation status of the engine company? The China Truck Network reporter went to related departments to understand the situation on this issue.
Engine companies go all out to meet the country IV
The Ministry of Environmental Protection's “Announcement on the Implementation of National Phase IV Standards for Vehicle Combustion Engine and Vehicle Pollutants Emissions†states: Since July 1, 2013, all vehicles produced, imported, sold, and registered have been compression-ignited. Engines and cars must meet the requirements of the National IV standard. The internal combustion engine industry has begun to go all out to meet the implementation of the National IV.
In fact, in order to reduce tail gas pollution from commercial vehicles, the Ministry of Environmental Protection has planned to implement IV emission standards for commercial vehicles nationwide on July 1, 2011 and January 1, 2012. However, due to problems in the company's technical reserves and oil quality, it has repeatedly been postponed. . At the recent meeting of the secretary general of the internal combustion engine industry branches, Xing Min, executive vice chairman and secretary general of the China Internal Combustion Engine Association, said that he takes the lead in advocating the implementation of the National IV emission standards. The whole industry of the internal combustion engine has a very big overall concept and has a clear-cut attitude towards the implementation of the National IV emission standards, indicating that preparation work is well-established. For more than a year, the backbone enterprises in the internal combustion engine industry have also used their actions to enhance their respective strengths. Engine manufacturers are pushing new products one after another.
The reporter learned from the market visit that many users have concerns about the implementation of the new national standard IV. Apart from questioning the upgrading of oil products, the main issues are whether the quality of the Chinese IV engine can be reliably guaranteed. In recent years, Cummins ISF series of environmentally-friendly engines have performed well in domestic and foreign markets and have won widespread trust from users both at home and abroad. Mr. Chen from the Shenzhen area said in an interview with reporters that his truck is always equipped with the Cummins ISF Series IV engine, and there is no concern about the current implementation of the National IV standard, and the quality of the Cummins ISF Series IV engine is trustworthy.
It is understood that the Cummins ISF series of light flagship power emissions standards ahead of many similar domestic engine products, while having excellent quality performance. The rigorous road reliability test, modular design, and Bosch high-pressure common rail technology were unanimously approved by the end-user experience. Its 500,000 kilometers did not overhaul users' search activities, and even raised a high-quality banner in the hearts of truck drivers.
The National IV Forward March The Cummins ISF continues to optimize the implementation of this emergency march in the National IV. The major engine companies can be said to have full confidence and the number of China IV products introduced is not limited. Compared with many engine products, as early as in 2009, Cummins ISF IV engine has been put on the market, technology and product quality after nearly three years of market testing, to meet the national IV standards of technology upgrades can be described as a well-known road.
In the face of the diesel IV emission standards to be implemented on July 1, the Cummins ISF is by no means an unprepared battle. Cummins ISF IV products have been put in place since the end of 2009. Therefore, strict emission standards have not yet been implemented in China and the sales volume of China IV products is limited. However, in areas that are relatively strictly enforced, ISF's China IV products have been leading and accumulated a lot. Practical application experience and ensure continuous optimization of the product.
At present, the Cummins ISF product line already covers products from Euro III (State III) to Euro V. Users include Futian, Jianghuai, Chery and many other domestic vehicle manufacturers, as well as Russia-based GAZ, which is dominated by Euro IV. Users of the Brazilian Volkswagen Man, South Korea's Daewoo Bus and Australia, Europe and other higher emission standards markets. At present, Euro VI products that are mainly sold in European and American markets are also in the project stage and are expected to be put on the market soon. As of June 2013, the total number of ISF countries IV and higher standard products put on the market has exceeded 50,000 units. Among them, the Russian market has sold more than 20,000 units; the Brazilian and South Korean markets have sold a total of nearly 30,000 units, and the product application covers trucks and buses.
At the moment of the implementation of the National IV Standard, the excellent performance of the Cummins ISF engine, advanced emission technology, excellent reliability, and a perfect match with the OEM will surely win a broader market prospect.
Widely adapting to the end-user benefit of oil products According to various sources, we can understand that there are numerous technical problems behind this long-running implementation of State IV. The specific implementation effect of the State IV still needs time to answer. However, in the implementation of the National IV, engine and oil are the two most important factors. Fu Chengyu, chairman of Sinopec, said: While improving the quality of oil products, we must also increase the technical level of the engine. If the car engine fails to meet the standards and eats "fine grain," it will still not meet the emission standards and will not achieve the environmental protection effect. As the spear points to the engine, how will the engine company respond? Cummins ISF products exhibit extensive adaptability to differentiated oils.
Cummins ISF Euro IV (National IV) products compared to the country III standard products, the National IV products can bring users a more long-term value. First of all, it has a wide range of oil adaptability, which can be applied to the differences in oil products in different regions of the country to improve the distance between vehicles and reduce the cost of maintenance; Secondly, the fuel economy is further increased by 5-10% compared to the national level III engine. Saving more operating costs, due to reduced carbon particle emissions, correspondingly prolonged service intervals, reduced maintenance costs, and ultimately benefited end customers directly.
In addition, Cummins ISF IV products use fuel system pre-injection to make combustion more fully, further improve NVH, and make driving more comfortable.
Mature post-processing technology Cummins IV products have been upgraded to China IV by favored emission standards, which is a turning point for diesel engines. Starting from the national IV emission standards, in addition to the use of electronically controlled high pressure common rail technology to optimize the combustion process, it must also increase the external post-processing equipment to meet the emission standards. At present, Europe mainly uses two technical routes: First, SCR (Selective Catalytic Reduction) technology, that is, by optimizing the fuel injection and combustion process, as much as possible in the machine to control the generation of particulate matter, in the off-machine post-processing process, the use of urea solution Nitrogen oxides undergo selective catalytic reduction. The second is the EGR+DPF (Exhaust Gas Recirculation plus Particle Catcher) technology, which is based on exhaust gas recirculation, which suppresses the generation of nitrogen oxides in the machine. Particle traps are used to capture particulate matter in the off-machine post-processing process. According to industry insiders, although the gap between the technological level of Chinese auto companies and their foreign counterparts has narrowed, it is still difficult to reach the international advanced level. Experts believe that from the National II emission standards upgrade to the national III emission standards, the controversy surrounding the technical route continues, the fundamental reason is that China's auto and parts and components companies do not have the relevant core technology, do not make the appropriate preparations.
Faced with such severe domestic post-processing technology status, Cummins ISF IV products performed well. Cummins ISF Euro IV (National IV) products have two technical routes, SCR (Selective Catalytic Reduction) and EGR+DOC (Exhaust Gas Recirculation + Oxidation Catalytic Converter). These two routes have been widely used in North American and European markets. Their advanced nature and applicability have been fully verified.
Since China did not limit the technical route for national IV emissions after treatment, various post-processing technologies of Cummins ISF IV products were favored by the host plant. With the implementation of the global higher emission standards and the timetable for the EU-EU VI standards, the ISF is becoming an export weapon for overseas high-end light commercial vehicles and China's light commercial vehicle companies. At the same time, with the introduction of increasingly stringent emission regulations in the country, ISF products with mature Euro IV platform technology and rich application experience are expected to become the main driving force in the domestic light diesel vehicle market.
In addition, Cummins ISF fully considered the future emission upgrades at the beginning of design, and National IV is the starting point for product platforms. The same platform can be easily upgraded to Euro V and future Euro VI standards.
