On July 1, diesel vehicles will implement the National IV emission standards as the "heart" of the vehicle. Will there be any problem with production consistency of the engine? The reporter conducted a survey.
Car prices are as deep as
The National IV emission standard was postponed for nearly 30 months. During this period, all domestic engine companies have devoted themselves to research and development and strengthened their technical reserves. Many measures have also been taken to improve product consistency.
However, the reporter was puzzled that when calling various engine companies, the relevant responsible persons only clearly stated that the National IV products were ready, and all of them asked for consistency in product consistency. It seems that the issue was very sensitive during this period. This attitude of engine companies is worth pondering.
In this regard, some people in the industry believe that there are two main reasons why engine companies adopt such an attitude. “First of all, some companies’ national IV product consistency has not reached a very high level, so they do not want to make too many statements about the implementation of State IV. Second, companies with higher production consistency will also worry about the actual implementation of State IV. The actual effect of engine operation, after all, oil and urea are the actual problems. How much these factors affect the engine in the end, we must see through the practice to see." Industry analysts said.
It is worth noting that during the interview, relevant responsible persons of the engine companies mentioned the problems of post-processing, which further highlighted the importance of post-processing production consistency in the National Phase IV.
Country III is a lesson
"The implementation of the National IV will be on the horizon. Almost all engine companies claim that they are ready and have made technical reserves. But what exactly is the true effect? ​​Only when the vehicle is in operation can it be reflected." Insiders believe that in addition to oil and External factors such as urea and engine production consistency are also the key to the implementation of State IV emission standards.
Therefore, the person in the industry is concerned that due to the drive of interests, the State IV will repeat the mistake of “False Country IIIâ€. "When the State II upgraded country III, commercial vehicle companies adopted the route of high-pressure common-rail, but this caused the total vehicle cost to increase by 30,000 to 50,000 yuan, which caused a decline in sales to some extent. Because of the increase in tolls and car costs, it is more likely to choose cheaper vehicles, which will result in lower cost EGR technology.
Although it was quite controversial at the time, in the face of interests, many companies still followed suit regardless of the maturity of the technology, leading to a serious drop in engine production consistency. Facts have also proved that this technology is difficult to meet the national III emission standards, indirectly hindering the implementation process of State III.
In addition, at that time, even more tactics were adopted to tamper with the certificate, which severely disrupted the market order and further impaired the production consistency of engine products. “Industry sources told reporters that after upgrading the engine IV, due to the addition of a post-processing system, the cost will inevitably increase. In addition to the impact of oil products and urea, some companies may also “snapping the road†and then appear again like “false State III's situation.
To this end, the personage inside the industry suggested that the state should introduce a standard regulatory system and conduct a rigorous random inspection of engine companies. At the same time, companies should also shoulder the responsibility of energy-saving emission reduction, establish a corresponding quality assurance system and testing system, and strictly control the process to ensure product consistency.
