On May 25, Great Wall Motors issued a statement stating that Great Wall Motors submitted reporting materials to the Ministry of Ecology and Environment, the State Administration of Market Supervision and Administration, and the Ministry of Industry and Information Technology on April 11, regarding BYD Qin PLUS DM-i (product model: BYD7152WT6HEVC2), Song PLUS DM-i (product model BYD6470ST6HEV2) uses atmospheric fuel tanks, suspected of sub。

  

The problem of Great Wall Motors beating snakes and seven-inch high-pressure fuel tanks is a weakness that BYD can't get around.

    

What is a normal pressure tank?？According to professionals, the so-called "atmospheric fuel tank" is relative to the "high-pressure fuel tank."。

In a traditional fuel tank, in order to balance the pressure inside the fuel tank and prevent it from being deflated or expanded, the fuel tank needs to be connected to the atmosphere. In order to minimize the gasoline vapor in the fuel tank from being discharged into the air, the traditional approach is to install an activated carbon canister in the connecting pipe between the fuel tank and the outside to absorb the gasoline vapor, and then use vacuum to desorb it into the engine for combustion to avoid being discharged into。

For the atmospheric fuel tank system, the trigger threshold of the valve of the activated carbon canister is 4-7kPa, that is, when the fuel vapor pressure in the fuel tank reaches 4-7kPa, the fuel vapor valve on the fuel tank will open and the fuel vapor will be released Into the activated carbon tank, start adsorption work。

However, for DM-i hybrid vehicles (plug-in hybrid), because they mainly rely on electricity rather than fuel during driving, and the engine will not start in pure electric mode, resulting in activated carbon The chance of canister adsorption is greatly reduced, increasing the risk of gasoline vapor escaping from the exhaust port。In this case, the general practice is to upgrade the atmospheric fuel tank in the hybrid vehicle to a high-pressure fuel tank, and the fuel vapor will continue to be enclosed in the fuel tank under high pressure, and then enter the manifold through the carbon canister when the engine is running.。

It is reported that the high-pressure fuel tank can generally withstand a vapor pressure of 35-40kPa, and the pressure-bearing capacity is nearly 6 times that of the atmospheric fuel tank。It is estimated that if the high-pressure fuel tank is upgraded, the cost of the vehicle at this stage will be about 1,000 yuan higher.。

According to the "Limits and Measurement Methods for Pollutant Emissions from Light-Duty Vehicles (China Phase 6)" implemented on July 1, 2020 (GB 18352.6-2016), the country has made mandatory requirements for the evaporative emissions of volatile organic compounds from vehicles, and the high-pressure fuel tank is an important part of making up for the natural disadvantages of hybrid vehicle emissions。

Some people in the industry said that at present, whether it is independent or joint venture, except for some BYD plug-in hybrid models, all other car companies use high-pressure fuel tanks.。It is worth noting that the two BYD models named by Great Wall Motors this time are the star products of its plug-in hybrid series.。

Looking back at the report of Great Wall Motors, it again caught the weakness of BYD's partial hybrid that did not use high-pressure fuel tanks, and moved out of the "National VI" as its platform, which is quite a bit of a snake beating seven inches.。

   

Great Wall Motors has a long history of resentment BYD domineering response: test report is invalid

   

In fact, Great Wall Motor's "grudge" against BYD has been evident before.。In mid-May this year, at the launch of the Haver Xiaolong series, Great Wall Motor President Mu Feng repeatedly hinted that a car company was keen to control public opinion and focus on sales, while ignoring its own quality problems.。He said, "Some car companies regard 'controlling public opinion as the primary productive force', some car companies' spontaneously ignite while driving, but the A-pillar is deformed but silent ', and some car companies' win sales and lose the bottom line.'。At that time, there was a view that Mu Feng's speech was actually "insinuating" BYD.。

According to BYD's 2022 annual results announcement, BYD's annual cumulative sales during the reporting period exceeded 1.86 million vehicles, up more than 150% year-on-year, winning the new energy sales champion in China and the world in one fell swoop.。Entering 2023, BYD's sales growth momentum remains unabated, according to its published data, in the first quarter of 2023 alone, BYD's cumulative sales reached 55.210,000 vehicles, up 89% year-on-year.47%。During the 2023 Shanghai International Auto Show, Li Yunfei, general manager of BYD's brand and public relations department, also put down his rhetoric, saying that BYD is targeting sales of 3 million vehicles this year.。

On the other hand, Great Wall Motor, which was once a leader in its own brand, is currently in the throes of its transition to electrification.。According to its announced plan, the sales target of Great Wall Motors in 2023 is 1.6 million units, of which the proportion of new energy vehicle sales target is 40%, that is, 600,000 units.。For now, there's little hope of achieving that goal.。According to data, from January to April this year, the cumulative sales of new energy vehicles of Great Wall Motors were only 4.270,000 vehicles。

According to the latest data released by the China Automobile Association on May 26, BYD continued to be the champion of new energy vehicle sales in April 2023, with sales of 210,000 vehicles in the month, up 98% year-on-year..5%; while Great Wall Motor sold only 1.50,000 vehicles, significantly behind BYD。

In the face of the disparity in strength in the field of new energy, BYD's response is also quite confident, saying that Great Wall Motor vehicles do not meet the requirements, the test report is invalid:。Strictly speaking, the test vehicle does not meet the requirements of the national standard inspection status, that is, should be sampled, kept and submitted by a third party, and required to complete the 3000 km run-in test, while the Great Wall inspection vehicle mileage is only 450-670 km。In view of the above, we believe that the test report is invalid, the Great Wall can not be used as a basis! "

At the same time, BYD said in a statement that it firmly opposes any form of unfair competition and reserves the right to legal proceedings.。BYD products and related testing in line with national standards, in the national authority through certification, welcome the relevant departments at any time to come to investigate, evidence and testing。

In addition, Li Yunfei, general manager of the brand and public relations department of BYD Group, also fought back strongly on social media: "Blowing out the lights of others will not make you brighter; blocking the way of others will not make you go further."。"

However, BYD did not respond in a statement on whether to use atmospheric fuel tanks.。However, according to relevant information, on March 30, 2021, BYD applied for a patent project of "Oil and Gas Management System and Vehicles with It." It was mentioned in its background technology that due to the volatility of gasoline, the fuel in the fuel tank The gasoline will generate steam due to volatilization, which will increase the pressure in the fuel tank。If the fuel vapor in the fuel tank is not processed, a high-pressure fuel tank needs to be set up to meet the demand, which will increase the cost。

Affected by the reported incident, Great Wall Motor, BYD May 25 afternoon stock prices both plunged, as of the close, Great Wall Motor fell 6.17% to 24.8 yuan, its Hong Kong stocks fell 7.31% to 8.HK $37; BYD down 2.41% to 255.6 yuan, Hong Kong shares of BYD fell 5.4% at 234.HK $6。

   

Great Wall Motor drunkard is not interested in wine The essence behind the "high-pressure fuel tank" problem is the problem of hybrid market competition.

   

At present, the Great Wall Motor reported BYD, it seems that behind a lot of their own calculations。

On the one hand, Great Wall Motor, as the king of the local oil car, this time the first "lead war" can indeed re-expose itself to the spotlight, and even get higher than BYD's short-term heat, in the new energy track to expand its exposure.。In addition, after the first bullet, the follow-up BYD will also usher in the relevant departments of quality inspection and investigation, and even self-inspection spot checks, when the Great Wall may take this opportunity to launch another round of public opinion offensive, the market will also be highly concerned about this event.。

On the other hand, Great Wall just released its own hybrid products Haver Xiaolong and Haver Xiaolong MAX in mid-May this year, both of which are divided into three models, positioned as compact SUVs and medium-sized SUVs, and the prices are within 200,000 yuan.。According to industry insiders, whether it is the technical route or price range of Haver Xiaolong and Haver Xiaolong MAX, the target products are BYD's Song PRO DM-i and Song PLUS DM-i.。

In retrospect, the two models that Great Wall attacked BYD this time, the Qin PLUS DM-i and the Song PLUS DM-i, have both performed brilliantly recently.。In February this year, BYD Qin PLUS DM-i launched the 2023 championship version to 9.The starting price of 980,000 yuan broke through the last line of defense for joint venture fuel vehicles, and the price of DM-i models dropped to less than 100,000 yuan for the first time, and in April directly won the car sales crown; and BYD Song PLUS DM-i also in April this year with 2.Sales of 060,000 vehicles ranked fourth in compact SUV sales, making great contributions to BYD's opening up the market for this series of SUVs。

It is worth noting that, according to media reports, before 2022 Great Wall Motor's Haval H6 had dominated the domestic SUV market for many years, but BYD Song, once it came out, directly pulled it down from that position, and reached the top of the SUV market that year.。In addition, the Great Wall statement disclosed to the three departments to "submit reporting materials" time for April 11, but until May 25 to disclose to the public, and this day, is the BYD Song Pro DM-i champion version of the plan to go public time。It can be said that BYD's Song series is really a thorn in the heart of Great Wall Motors.。

From this point of view, Great Wall Motors named and reported BYD this time. On the surface, it wanted to use the high-pressure fuel tank problem to beat BYD, but in fact, it is likely to match the offensive launched by Haver Xiaolong to make it in the current hybrid The car market has shown some deeds, and it is really a drunkard's intention to kill a carbine.。

Last night, Great Wall Motor issued another announcement, saying that the company released the Statement on the morning of May 25, 2023 through Great Wall Motor's official WeChat public number and other channels.。If the follow-up progress of the relevant matters involves the need to fulfill the obligation of information disclosure, the Company will fulfill the obligation of information disclosure in a timely manner in accordance with the requirements of laws, regulations and listing rules.。

In addition, the Great Wall also revealed the current operating conditions of the company in this announcement.。The company said that as of now, the company's operating conditions are sound and there have been no significant changes.。In terms of revenue, in the first quarter of 2023, operating income was 290.3.9 billion yuan。In terms of sales, the company achieved 6.20,000 vehicles, 6.80,000 vehicles, 9.0 million, 9.30,000, up 73 in April.14%。In terms of exports, the company's cumulative overseas sales from January to April were 7.40,000 units, up 99.1%。

For BYD, the current situation has been a bit of a tiger.。On the one hand, at a time when public opinion is highly sensitive, any caliber of its "soft underbelly" high-pressure fuel tank problem will presumably be weighed.。On the other hand, if the two models of BYD really fail to pass the quality inspection, the company's reputation will be hit, the company will also face fines, recalls, technical improvements and a series of problems, its manufacturing costs will also be affected.。Especially after the National VI B New Deal boots landed, BYD's high-pressure fuel tank problem may really be a time to be resolved.。

In November 2021, BYD had generously transferred the "Wei" trademark to Great Wall Motors, at which time the two were still sympathetic to each other.。At the time, BYD said: "BYD submitted an application for registration of the 'Wei' trademark in January 2016 and decided to transfer it to its partner Great Wall Motor this year.。Meanwhile, Great Wall Motor transfers other registered trademarks to partner BYD。The two sides will work together to achieve the common progress of Chinese brands。"

Now it seems that the two are against each other and are not very sad.。
