In the truck industry, China IV has become a hot topic, and all kinds of positive or negative information have come. However, when discussing State IV, one thing should not be overlooked. What is the status of implementation of the State III standard (implemented in one year in some regions) implemented in 2008? After all, many problems exposed by the State II State III have important implications for the new round of emission upgrades.

Some people may think that the State III that has been performing for many years should have “nothing to say”, but the reporter’s investigation found that in the field of light trucks, the implementation of the State III is really unsatisfactory.

It is still changing medicines. “In rural areas in Hebei, the light trucks sold by distributors have all been announced by the State III, but I always feel that it is actually not up to the national III level. I suspect they are actually products of State II.” The brand light truck dealer Mr. Zhang told Commercial Automotive News: “This is not my guess. The current state III heavy truck generally adopts supercharging technology, while the light truck products do not use this technology, let alone high pressure common rail and EGR. It's up."

Mr. Zhang holds the same view as Mr. Zhang, a light truck dealer in Henan.

"Although light trucks have already implemented the National III standard a few years ago, it seems to me that they are actually changing the market. It is difficult to see the real State III products on the market. At least, most of the light trucks we sell now are used. II engine." Mr. Ren introduced: "Do not say anything else, just look at the fuel injection pump will know. State I light truck is a naturally aspirated engine; State II engine has a turbocharger, can use the exhaust gas Up, the use of a mechanical pump; State III is a revolutionary improvement, the State III engine using EFI technology, fuel injection accuracy is higher, more fuel-efficient; to the national IV stage, more than the State III, a urea tank, this It is to reduce the emission of nitrogen dioxide. Therefore, the oil pump of State II simply fails to reach the level of State III."

On the one hand, the National III standard for light trucks has already been implemented; on the other hand, the market has been flooded with national II products. In order to "balance" this contradiction, falsification came into being.

“Although the light truck products are actually the national II level, they all use the national III certificate. Even if it is necessary to go on-line to detect exhaust gas, it can almost pass.” Mr. Ren said: “This is not a question of a certain brand, but everyone In this way, because no one has come to supervise, it will only take money to get things done. Therefore, despite the fact that State III has been performing for such a long time, the market is still filled with this kind of “hanging things and selling dog meat”. There is no strict enforcement of laws and regulations, or strict requirements in some places, and some places are not strictly required. In short, I do not think that State III of light trucks has been strictly implemented."

In the interview, the manufacturer also stated that the light truck country III emission standard has not been strictly enforced. This phenomenon has existed for a long time. At present, when discussing the implementation of lighter diesel vehicle IV emission standards, it is better to strengthen supervision, and truly put the country III. Standards are implemented.

Multiple factors leading to poor implementation <br> <br> reason why there is such a dilemma, a substantial increase in costs is an important reason. "The State II light trucks are 20,000 to 3 million cheaper than the country's light trucks," and the dealer's words reveal the truth.

According to reports, in order to meet the national III emission standards, the following types of technical routes can be used: First, electronic control + high pressure common rail; second, electronic control + monomer pump; third, electronic control + pump nozzle. Assembly of electronically controlled high pressure common rail system, the total cost of the engine increased by more than 10,000 yuan; the use of electronically controlled + monomer pump technology and electronic control + pump nozzle technology, engine costs will increase 5000 ~ 6,000 yuan. In various types of vehicles, the cost of light diesel vehicles has increased most significantly. For rural users who purchase low-end products and have limited economic capacity, the unified implementation of State III will undoubtedly make them feel beyond their control.

"A light truck was only a few tens of thousands of yuan. After upgrading to the National III, it increased so much at once. This increase exceeds the user's expectations and acceptance." Mr Ren said.

The second big issue is oil products. "I have sold Mercedes-Benz from Germany before. Since the domestic oil products are not up to standard, I can only add oil separators and filter the diesel oil again so that it can be used only. However, the oil-water separator on the back of the light truck is unrealistic because oil and water Separator to 6000 ~ 7000 yuan, light trucks only 30,000 to 40,000 yuan, it is worthwhile.Not up to standard oil damage to the engine, especially for the injector, a brand previously produced engine can not run 10,000 Kilometer has to change the nozzle, a set of 10,000 yuan, who can stand it?” Mr. Ren told reporters.

Manufacturers Call for Strict Implementation of State III

Although there are still many problems, but in the era of increasing awareness of environmental protection and increasingly stringent environmental regulations, whether it is users or manufacturers, distributors, everyone is looking forward to find a good way to effectively solve the pressure of pollution and costs.

"From the user's point of view, their needs are two-sided. On the one hand, users do not want to pay too much for the upgrade of emission standards; on the other hand, the past few years have seen severe haze. More and more stringent, users are increasingly concerned about the level of vehicle emissions, because it involves the use of time limit, if it is characterized as yellow standard car, the vehicle can not enter the city." Mr. Zhang analysis said.

"As distributors, we also hope to strictly implement the State III. Manufacturers have the same desire, because emission standards will be upgraded sooner or later." Mr. Ren said: "For manufacturers and distributors, as long as they stand at a starting line, it does not matter. For example, this brand provides the market with the products of State III, and other brands do not provide it, what should be done?The time passed and the accounting was finished at the end of the year. Both sales and market share Obviously different, who can afford the consequences? In this way, who would dare to be a 'crab-eating person'? However, if everyone expects other people to come out first, then the end result is that no one else has his head. Therefore, the State III Strict enforcement also requires strict laws and regulations and strong supervision."

On this basis, the experts suggest that, in view of the domestic demand for high, medium and low-end models, on the one hand, it can continue to advance advanced high-pressure common rail systems to achieve better comfort and better emission levels; On the other hand, we also need to adopt other solutions that suit our specific national conditions in terms of prices and usage conditions.

"To realize emission upgrading, we must apply new technologies. Who should bear the costs arising from this? From the perspective of international development laws, most countries are taking the path of government purchases, enterprises tapping potential, and consumers taking part. The situation in our country is that the government has not provided relevant preferential policies and supporting policies, and consumers do not want to pay more. It is unreasonable to put the burden on the shoulders of diesel engines and car companies. This is the deputy secretary of the China Internal Combustion Engine Industry Association. Wei Anli said: "The fiscal and taxation policies should be adopted to encourage the diversification of technology and to mobilize the enthusiasm of the enterprises. In order to encourage the engine and vehicle companies to save energy and reduce emissions, the VAT refund method is generally used to compensate enterprises in the world. If China can also learn from VAT refunds and other means to achieve 'government pay, enterprises tap potential, consumer burden', then companies will be more active and initiative to achieve the goal of energy conservation and emission reduction, rather than trying to find a way out."

The sales and registration of regional N-type light-duty diesel vehicles can be transitioned for one year.
