Since the implementation of the "National IV" diesel engine , it has been a surprise step forward in all kinds of doubts and concerns since its implementation, from the erratic implementation time to the oil quality problem, to the "Fake Country IV" caused by The industry is awe-inspiring, "National IV" has always been a word without missing a topic. Today, the national authorities have used facts to tell everyone that the country is coming.

A few days ago, the Ministry of Industry and Information Technology issued an announcement stating that in order to implement the “12th Five-Year Plan for Energy Saving and Emission Reduction” and the “Air Pollution Prevention Action Plan” to promote air pollution prevention and control, reduce automobile exhaust emissions and protect the rights and interests of consumers, the Ministry of Industry and Information Technology is scheduled to On December 31, 2014, the "Announcement" on diesel vehicle products applicable to the third phase of the State's automobile emission standards (hereinafter referred to as Guosan) was abolished, and on January 1, 2015, the state-owned diesel vehicle products will not be sold.

At the same time, the announcement also requires all production companies to actively prepare for the production of products that will be upgraded and discharged, reasonably arrange the sales of the products of the National Diesel Engine Group, and do a good job in the consistency management of vehicle production. The official announcement of the announcement shows that China National Diesel Engine has already ended its historical mission and the country has ushered in a truly national era.

Completed after wave of twists and turns

From the time when the National 4th Standard was proposed to the formal announcement of the exit of the National Diesel Engine from the market, it was a series of twists and turns. From the very beginning, according to the plans formulated by the relevant national ministries and commissions, it was announced that the National 4th Standard would be fully implemented starting from January 1, 2011. However, on December 21, 2010, 10 days before the implementation was expected to be implemented, the relevant departments announced that the plan that was scheduled to be implemented on January 1, 2011 was postponed until January 1, 2012. Afterwards, due to the failure of oil products, they were postponed until January 1, 2012 and July 1, 2013.

However, on July 1, 2013, the fourth national standard was postponed for the third time, and the reason was still oil products.

In the process of repeated official and repeated delays, four engines of fake countries have emerged in an endless stream. Some unscrupulous manufacturers have converted the engines of State Three or even State Two into four engines of the State for sale for sale, exploiting policy loopholes and seeking benefits. .

At present, the oil products of the Fourth National Government have been brought to the market. There has been no problem with the oil products that have been criticized. The real national standard will also be officially implemented next year. The implementation from the country two to the country three can be said to be relatively smooth, but the implementation from the country three to the national four can be said to see the rainbow after experiencing the storm.

According to industry insiders, the lower fuel quality restricts the use of vehicles and the effects of emissions; China's commercial vehicle and heavy-duty diesel engine manufacturers have their own brands and their technology reserves are insufficient; commercial vehicles and heavy-duty diesel engines that meet higher emission standards are often required to increase The cost of tens of thousands of yuan is not acceptable to users. Among them, the oil problem is considered to be the main reason.

The implementation of national standards, the use of common rail technology in the rear of the vehicle to add SCR (selective catalytic reduction), now common rail technology and SCR are mostly in the hands of foreign companies, it should be on the common rail and SCR, there is no way to meet the domestic car Enterprise requirements. In addition, the installation of SCR requires the addition of urea to the gas station. The current number of road stations in the urea supply point is still insufficient.

It is so difficult for the transformation of the country from country 3 to country 4. This reporter deliberately made an understanding. It is understood that the technical upgrading of the engine of the State II upgrade to the national standard is relatively small, simply said that the improvement of the fuel injection system and the installation of the electronic control system on the basis of the original State II engine will enable it to meet the State III emission standard. This technological improvement has little increase in the cost of the engine.

It is not so simple to upgrade the country three to the national four, because China's national four upgrade emission standards implement the SCR technology line, which requires the addition of a complete set of exhaust gas after-treatment system on the basis of the original engine, and this cost is Relatively high, at the same time, because the post-processing system uses urea as a catalyst, in order to meet the national IV emission standards, there is also a certain requirement for the exhaust gas before processing, and this involves the problem of engine oil products, because There is no opportunity for oil products in the process of the country’s second national upgrade. The cost of the engine, the neglect of the oil problem and other factors have made the implementation of the National IV difficult.

Industry self-regulation is the key

The introduction of policies and regulations is to purify the industry air and make the industry develop healthier. However, a good method cannot be effectively enforced, and even knowing the law is illegal. It is like the Pearl darkcast and has no effect.

Not long ago, a number of companies in the industry were exposed to the "Fake Country IV" incident in which three engines were used instead of the four engines. After this incident was exposed, it attracted the attention of the industry to various issues such as the implementation of national standards and industry self-discipline.

Subsequently, the China Association of Automobile Manufacturers held a special press conference for “Fake Country IV”, announcing that the major domestic truck manufacturing companies will implement industry self-discipline and resolutely implement the four emission standards for heavy-duty diesel vehicles. At the press conference, on behalf of the member companies of the China Trucking Manufacturers Association, the China Automotive Industry Association released the “Self-discipline Promise for the Implementation of the Fourth Emission Standard for Heavy-duty Diesel Vehicles by the Member Companies of the China Trucking Manufacturers Association”.

At present, the members of the organization are FAW Jiefang Automobile Co., Ltd., Dongfeng Commercial Vehicle Co., Ltd., Shaanxi Automobile Group Co., Ltd., China Heavy-duty Truck Group Co., Ltd., Beiqi Foton Motor Co., Ltd., SAIC Iveco Hongyan Commercial Vehicle Co., Ltd., and Anhui. Jianghuai Automobile Co., Ltd. and Dongfeng Motor Co., Ltd.

This commitment is to ensure that the state-four heavy-duty diesel vehicles designed, produced, and sold all use electronically-controlled oil supply systems. They do not adopt atypical technical lines that cannot continuously meet stringent standards, and are likely to cause market confusion and affect market supervision, reflecting technological progress. The state-four heavy-duty diesel vehicles guaranteed to be produced and sold meet the National IV emission standards and eliminate the country's three-and-lower emission standards for vehicle-applied country-four certification sales. Ensure the consistency of production control, and actively cooperate with the supervision and inspection of relevant departments. Strengthen industry self-discipline and jointly maintain the reputation of the trucking industry. Seriously accept and actively cooperate with the supervision and inspection of government departments. To strengthen mutual supervision, if found that the defaulting company first conducted an open written inspection in the Joint Committee, and once again violated, disqualification of member units.

From the terms of the commitment, it can be seen that its most severe clause is only "disqualification of the member organizations of the Joint Council," and the China Automobile Association also acknowledges that there is no more severe penalty, but for the members of the joint committee, it is like this. The “disqualification” of the industry organization will also be a scandal that shocks the industry.

Dong Yang, executive vice president and secretary-general of the China Automobile Association, said that the relevant companies must strictly follow laws and regulations to conduct business management, and the company’s actions to sell the country’s three vehicles instead of the country’s four vehicles will be immediately rectified.

Deeper contradictions remain

Some commentators pointed out that at present, domestic fake cars and four cars have an average price of more than 10,000 yuan compared to the four cars in the real country. Moreover, the four cars in the country are demanding for oil products, and they also need to add urea, which will not only increase the cost but also obtain urea. Inconvenient, therefore, the revenue from the sale and use of Fake Kokubu is much higher than that of Fukuda IV. In addition, from the perspective of costs, the proportion of investigations and handling of Fake Kumamoto is very small, and the penalty amount is very low. These are the reasons why the fake four cars must appear on the market.

It is not just the “Fake Country 4” incident triggered by higher returns. More deep-seated contradictions are looming behind this incident. For example, in the case of domestic companies failing to solve advanced engine technologies such as high-pressure common rails, it involves the supply of national four engine resources. Dong Yang revealed: "Now there is a certain amount of resources to ensure that there is no matching problem, there has been a certain degree of inequality, discrimination." Dong Yang stated that the China Automobile Association will coordinate handling, but also admitted that the National IV engine technology "restrained by people."

At the same time, the China Automobile Association also disclosed earlier this year that as of April, the China Automobile Association’s survey on sales of 672 gas stations in 18 provinces and 2 municipalities showed that none of the 672 gas stations had special applications. For injection equipment, only 2% of gas stations supply small packages and bottled products; in 145 large auto parts service companies in 73 prefecture-level cities in 18 provinces, the supply rate of bottled urea is only 58%. At the same time, the supply of national standard diesel is only 10%.

The problem of unclear ownership of supply and supervision of urea in the automotive sector. Regarding the possibility of oil companies collaborating with diesel, Dong Yang thinks that it is not feasible. At present, the general technical level of the urea industry is not high, it is difficult to guarantee the supply of urea and the use of consumers, and oil companies cannot be held liable. And in the future, issues such as monopoly and procurement discrimination may arise.

In response to the heavy lifting of the issue of China's four standards, the system, technology, and standards that the internal combustion engine companies faced in the process were resolved under the attention of the government, society, and companies.
