In 2010, the domestic heavy-duty engine market received exciting statistics: Only the national sales volume of heavy trucks soared from 630,000 units in 2009 to 1 million units, an increase of more than 50%; and large-scale infrastructure projects such as airports and high-speed rails. It also provides more space for construction machinery, a heavy-duty engine application. The second largest expressway network in the world, with a total length of 74,000 kilometers, enables the intensive utilization of heavy trucks in logistics to be better played; the hottest infrastructural infrastructure in the world has enabled the construction machinery market to flourish. Under this general trend, the domestic diesel engine manufacturers have moved up the power section of the original product. This segment of the market, known as "gold displacement," has begun to bring real profits to the manufacturers.
Industry experts at the internal combustion engine exhibition asked the staff about the status of the Z series engine
A few days ago, the reporter learned from Dongfeng Cummins Engine Co., Ltd. that its Z-series 13-liter engine with power ranging from 400 to 550 horsepower has been successfully launched since the advent of the 2009 market, and has successfully matched many companies in 2010. Trucks and construction machinery have been recognized by users for their application in a variety of complex conditions.
The cooperation between Dongfeng Cummins Automotive ISZ engine and truck manufacturers is mainly reflected in the tractor. After testing under a variety of complex conditions, this engine reflects a good overall machine matching performance and adaptability. In many truck and logistics exhibitions, the Dongfeng Cummins ISZ 13-litre heavy truck combines powerful power, atmospheric appearance, good handling comfort and fuel economy, attracting the attention of industry professionals and end-users. The Dongfeng commercial vehicle makers said that the strong performance and stable performance of Dongfeng Cummins ISZ engine provided strong support for its forward-looking heavy-duty platform and will become the mainstream heavy truck for Dongfeng Commercial Vehicles in the next 3-5 years. The market's important dynamics match.
In the construction machinery market, Shanghai Gudeng Construction Machinery Manufacturing Co., Ltd., one of the construction machinery manufacturers that maintains close cooperation with Dongfeng Cummins, highly praised the Dongfeng Cummins QSZ 13-liter engine. In 2010, the company installed the Dongfeng Cummins QSZ engine on the non-excavation rig for the West-East Gas Pipeline related project. “This is a national key project. The construction environment is complex, and the geological conditions are very poor. The 10 QSZ engines are very stable in operation, and they are also very dynamic. The fuel consumption is also very good.†The company staff said. It is not only the reliable quality of QSZ that satisfies them, but also the after-sales service guarantee of Dongfeng Cummins: As a new product, Dongfeng Cummins dispatched service engineers and manufacturers to communicate with each other carefully during the machine fitting period to understand the user during use. The various demands that may arise, prepare in advance and respond to user problems as soon as possible after the machine is put into use.
The reason why Dongfeng Cummins has paid so much attention to the 13-liter project is, of course, based on market demand: The expansion of the market size of “gold displacement†makes the horsepower segment with the highest profit margins available to both vehicle manufacturers and engine manufacturers. More space; Secondly, Z series engines have special strategic significance for Dongfeng Cummins: It was commissioned by Cummins Inc. of the United States by Dongfeng Cummins. Dongfeng Cummins has completely independent intellectual property rights and its products are globally competitive. It is both Dongfeng Cummins Inc. The manufacturing and marketing functions are a key step in the development of R&D, manufacturing, and marketing, as well as a breakthrough in strategic technology products for heavy-duty engines in China. It can be said that the 13-liter heavy truck project will, to a certain extent, guide the direction of Dongfeng Cummins' future technology and product development.
Such a heavy-duty product, of course, must be world-class in the core technology sector: in terms of emissions, it uses Cummins Emissions Processing Systems (CES)'s selective catalytic reduction technology, which not only meets the country's four emissions, but also faces the European V and the US EPA 2010. The smooth upgrade capability of the above regulations, and its backward extension, can greatly reduce the follow-up upgrade costs of vehicle manufacturers. Cummins Engine reliability, which is praised by users, is also ensured through Cummins' global product development process: In the test, the cumulative operating time of the 13-liter engine reaches 30,000 hours, and more than 20,000 hours of effective bench tests will reach 6 million kilometers. The road test has also undergone extreme environmental experiments such as high altitude, high temperature, cold, and high humidity to ensure its reliability and power in harsh environments.
The advent of celebrity products has also attracted the attention of many media and industry players: At the 2010 China International Journal on Internal Combustion Engines (Beijing), the internal components of the 13-liter engine and its operating mode at slow speed were dynamically anatomized. Presenting it, it has caused many people in the industry and the media to stop watching and researching. It has also become a bright spot in this exhibition.
In recent years, some of the heavy-duty truck engines in the European market have exceeded 700 horsepower, and the torque also exceeds 3000 N·m. Engine emissions can meet Euro V. Looking at the domestic market, with the further increase of freeway mileage and the leap in logistics conditions, the proportion of heavy trucks in the truck market pie will increase significantly in the future. The relevant person in charge of Dongfeng Cummins Engine Company stated that: Z series heavy-duty engines are the strategic decisions made by Dongfeng Cummins based on the development trend of “lighter, lighter, and heavier lighter†in the engine market, which is to expand the product line and improve the competitiveness of the company. As one of the key steps, with the further “fermentation†of the heavy-duty engine market, Dongfeng Cummins will invest more resources in 2011 and jointly develop Z-Series engines with the host manufacturers as a strategic product.
PVC Resin
PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.
PVC Resin usually inculde carbide based and ethylene based. K66-K68 PVC RESIN, K59-K55 PVC RESIN, K71-K73 PVC RESIN. PVC RESIN SG5, PVC RESIN SG3, PVC RESIN SG8.
According to the different application scope, PVC can be divided into: general-purpose PVC resin, high polymerization degree PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a crosslinking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
According to the method of obtaining vinyl chloride monomer, it can be divided into Calcium Carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. Suspension process polyvinyl chloride is the largest variety in output, accounting for about 80% of the total output of PVC. Suspension method PVC is divided into six models according to absolute viscosity: XS-1, XS-2--XS-6; XJ-1, XJ-2--, XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-compact type.
