It is reported that according to the regulations of the State Environmental Protection Administration and the General Administration of Quality Supervision, Inspection and Quarantine, the new domestic heavy truck model will formally implement the national III standard from next Tuesday, that is, on January 1, 2008, and the heavy truck that fails to meet the national III emission standard will not be listed. Sales. The state will also implement the national IV standard on January 1, 2010 and the implementation country V standard on January 1, 2012.
In response, Guo Huanan, head of the Propaganda Department of China National Heavy Duty Truck Group, believes that implementing country III will increase the price of heavy trucks. It is expected that the heavy truck products will be adjusted upwards by 10% to 15%. Therefore, as soon as possible to develop a new type of engine and try to reduce the cost of manufacturing technology, it will become an urgent problem for major companies to solve.
According to reports, the essence of State III is to make the engine change from mechanical to electronic. The most important of these is to upgrade the engine fuel injection system. At present, this technology is limited to the internationally-available electronically controlled high pressure common rail. Due to the shortage of resources, the cost of the engine will be greatly increased due to competition. Secondly, in the short term, the oil adaptability cannot be matched. If the State III vehicles use the fuel of the State II for a long period of time, it is very likely to damage the vehicle performance and affect the service life of the engine. Thirdly, the State III vehicles use foreign technology electronic engines. Once more complicated breakdowns occur, maintenance is very troublesome.
In order to break through these major bottlenecks and seize the commanding heights of the National III engine competition to meet the needs of the national automobile emission regulations, this year, major domestic heavy truck companies have rushed to introduce advanced engines and push new products. FAW, Dongfeng, and CNHTC took the lead with the advantages of vehicle and engine integration, and launched the “King Prince†series of heavy-duty engines of the State III; Shaanxi Automobile was dominated by Weichai Power WP10N and WP12N III engines. The company has successfully developed a full range of trucks, dump trucks, tractors, and special-purpose vehicles. It claims that it has solved three major bottlenecks: fuel injection technology, professional service support, and oil product adaptability; Beiqi Foton has already established a joint venture with Cummins. Factory; Chongqing Zhongqi and SAIC, Iveco joint venture, the engine production is also within the scope of the joint venture. The rest of the heavy truck companies are also looking for partners to research and develop new engines and are ready to face the new market competition in 2008.
Glossary
What is State III?
State III, the third phase of national motor vehicle emission standards. For heavy-duty vehicles, it is precisely defined as that the exhaust emissions of heavy-duty vehicles reach the “Limits and Measurement Methods for Exhaust Pollutants for Compression Ignition, Gaseous Fuel Ignition Engines and Vehicles (Class III, IV, V)†The third stage emission control requirements in (GB17691-2005). Specifically, the concentration of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), PM (particles, soot), etc. in vehicle exhaust that meet the National III emission standards is higher than that of the national II emission standard. Vehicles are 30% to 50% lower.
