In this regard, people with passenger car companies told reporters that most of the current gasoline vehicles, especially passenger cars, have been able to achieve the national five emissions, so almost all can meet the requirements, but to meet the new standards, diesel vehicles may be more under pressure. According to the reporter's understanding, compared with the national four, the national five gasoline vehicles are mainly stricter emission limits of nitrogen oxides, and new hydrocarbons other than methane and particulate matter concentration detection standards for gasoline vehicles directly injected into the cylinders have been added. For diesel vehicles, the requirements are relatively higher, not only the nitrogen oxide emission limit is stricter by 28%, the hydrocarbon and nitrogen oxide total is also stricter by 23%, and the particulate matter concentration limit for diesel vehicles is increased. 82%. Not only that, but there is also a measure of the amount of particulate particles specifically for diesel vehicles.
However, an insider of FAW Xichai told the "First Financial Daily" reporter: "For large engine manufacturers, the advance upgrade of emission standards is also good." According to its introduction, upgrading from the national four to the national five In fact, from a technical point of view, the route from the third country to the fourth country is almost identical. On the one hand, the high-pressure common rail technology is adopted to improve the fuel efficiency of the engine and the combustion is more complete. On the other hand, the catalytic reduction technology is used to treat the exhaust gas at the rear end, and the particle trap DPF is added in the post-processing. Of course, due to the addition of new technologies and the use of precious metals in the DPF, there will be an increase in costs associated with electronic control systems, EGR (exhaust gas recirculation) upgrades, and combustion optimization.
Yang Honghai, the public relations director of SAIC Commercial Vehicles, told reporters that the cost is about 15,000 to 20,000 yuan. Nonetheless, in the above-mentioned FAW Xichai insiders, in the current context, in fact, the purchasers of commercial vehicles, especially large logistics companies, have not valued the cost of a single car at the front end. "On the contrary, they More emphasis on the efficiency of the delivery and the cost of use throughout the life cycle." In his view, if companies can be prepared in these areas, the increase in costs will not have much impact on the end market. Not only that, but the strictness of standards is also conducive to the survival of the fittest in the entire industry.
"So we actually hope that the emission upgrade can be implemented in advance and can be strictly implemented." Yang Honghai told reporters. "On the one hand, SAIC commercial vehicles already have the technical reserve of the National Five. Not only that, but its products for overseas markets have already reached the standards of Euro 6. Now two sets of domestic and foreign standards, for enterprises, whether it is assembly Or the cost of materials will increase." Prior to this, a technical person from Suzhou Jinlong also expressed similar views to reporters when he talked about the postponement of the implementation of the standard of commercial vehicles. He believes that "the real thing that companies are worried about is not the implementation of standards, but the standards are not implemented." The reason for this is that although commercial vehicles in most parts of the country are still in the state of the fourth stage of emissions, Beijing will increase the implementation of the national fifth-stage emission standards by adding heavy-duty diesel vehicles before the end of this year. This means that commercial vehicle companies must meet this standard in order to enter the local market, and invest in the corresponding costs of research and development, verification, and testing. Because it is only for the local market, this cost is difficult to be spread in the short term. Sales, so companies are a headache for this "double standard."
Unlike most European models, which use diesel vehicles, the domestic models are mainly gasoline vehicles, and diesel vehicles have been carrying the nickname of “high pollution and high emissionsâ€. In the above-mentioned insiders of FAW Xichai, the important reason for the pollution of diesel vehicles is that the oil standards vary from place to place and the standards are not met. Therefore, if they can be unified and supply qualified diesel, perhaps the diesel car will usher in spring. Because according to the reporter, at present, the electronically controlled high-pressure common rail system provided by Bosch for diesel vehicles can save not only 25%~30% of fuel consumption, but also 30% lower than gasoline vehicles. CO2 emissions. If this is the case, in the new round of emission upgrades, foreign-funded parts companies with core technologies may benefit more.
