Original title: Automobile Pressure-stabilizing Oil Saver: High-tech or Big Fool?
In the era of high oil prices, how to save fuel has become the focus of car owners' attention. As a result, various energy-saving products came into being, such as gasoline detergent, oil-saving ointment, oil-saving pills, oil-saving essence and so on. Recently, an electronic stable economizer for automobile cigarette lighters is emerging. Searching online, there are many brands of this kind of voltage-stabilizing energy saver, and the price ranges from tens of yuan to several thousand yuan. Most of them advertise that their products have a fuel-saving effect of 5%-30%. Among them, several brands of economizer claim to have the test report of Tongji University Automobile College, which makes people more eager.
However, according to the reporter's investigation, Tongji University Automobile College is very upset about this matter. They only tested two kinds of fuel savers, and the difference in fuel consumption can only reach about 5% under extreme experimental conditions. Where does the 30% fuel saving rate come from? Experts say that all kinds of automobile fuel-saving products on the market are basically ineffective.
Tongji only tested two kinds of economizer.
"One tank of oil runs more 100 km, and the fuel saving rate reaches 9%-22% ..." These data are all advertisements from the fuel economizer of Jinmaichi automobile. Official website, another Carkani economizer which also runs 65,438+000 kilometers per box, has also made a vivid statement: "5%-30% fuel saving, 30% emission reduction ..." There are also brands such as Dapuli and Banghang.
These automobile pressure-stabilizing and fuel-saving devices inserted in lighters all claim to have the test report of Tongji University Automobile College.
Is it really Tongji University Automobile College that endorsed these fuel savers?
"It makes us very uncomfortable. We have also posted an announcement on the website of the Automobile Association to explain this matter. I don't know how these people can brag so much. We don't do this test now. " When receiving a phone call from a reporter, Zhou Yi, director of the new energy automobile engineering center laboratory of Tongji University Automotive College, complained.
Zhou Yi told reporters: "We only tested two types of economizer, namely Koenigsenke economizer in Shanghai in 2008 and stable economizer in Calconi, Xiamen in 20 10. These two fuel savers were made on new cars first, and they didn't work. Even if we find an old Santana 2000, we can't do it. Even if you keep accelerating and decelerating for ten cycles, you only make a fuel consumption difference of 100 kilometers twice, which is about 5.0%. However, when driving on the actual road, it is impossible to continuously accelerate and decelerate as during the test. "
Exaggerated myth of fuel saving rate
"Generally, we don't judge whether it is fuel-efficient, but for the first time our staff was inexperienced and wrote him a price difference of 5.0%. As a result, they went out to promote Tongji University and said that they could save fuel, which made us very embarrassed. " Zhouyi is very helpless. "In the second test, we were more cautious. What we are testing is an old car that can't meet Euro 3 standards. I just wrote all the emission values on the test report. "
The reporter obtained the test report of Xiamen Calconi Company's stabilized oil economizer from Tongji University, and all the emission values in the report were "unqualified". The experimental conclusion is that "HC, CO and Nox all exceed the specified standard values. Does not meet the Euro 3 standard. "
An old Santana whose exhaust emission can only reach Euro II standard has a fuel consumption difference of about 5% per 100 kilometers under extreme conditions of constant acceleration and deceleration. In the promotion of energy saver, it is said that the highest can reach 30%.
"I don't believe these things. I never use an energy saver. If the economizer can really reduce fuel consumption 15%, or even 30%, then the automobile factory has already used it, so why wait for them to sell it? 30% is impossible, and their fuel economizer manufacturers have to test it, saying that the fuel saving rate is 30%. If it is true, Americans will not have to fight Iraq. " Zhou Yi said humorously.
Test report of "wandering" everywhere
In addition to "kidnapping" Tongji University for exaggerated publicity, what is even more "wonderful" is that the test report made by Tongji University "wanders" on the websites of many fuel-efficient brands, which has become a magic weapon for many brands to attract funds.
Whether Kakoni's inverter, voltage regulator and economizer are "the latest Japanese technology, saving 5%-30% of fuel", Dapuli's automobile voltage regulator and economizer are "the world's first, German technology, reducing fuel consumption by 25%", or "all products are shipped from the original factory in Taiwan Province Province, and famous brands in Taiwan Province Province help us with inverter, voltage regulator and economizer", all the contents and data in their reports are the same as those in Tongji University 20.
"We have also seen these test reports online. As long as each page of the test report issued by our laboratory has a riding seal, these reports I have seen have no our seal from the second page. " Zhou Yi said. He said that Tongji is only responsible for the samples tested, and Tongji does not recognize the test report without a seal.
Stranger still, except for the same test report, the utility model patent certificate and the design patent certificate issued by these three economizer are exactly the same. Kakani has the latest Japanese technology, and Dapuli is German technology, which helped our bank to come from Taiwan Province Province. However, according to its patent number 200920 1365 17.8, the reporter learned from China National Intellectual Property Administration that the automobile fuel economizer pointed to by this patent number was invented by Zheng Wansen and Qian Xiaosi, and the patentee was Lin Tianlin of Huli District, Xiamen.
If these three fuel-saving devices are "copied" too obviously, then another well-known brand Jin Maichi, which is committed to "entering the 10 billion market", is "smart". It didn't list the patent certificate and test report in official website, but it mentioned in its advertisements that it had passed the actual road test of Tongji University Automobile College.
"We didn't test Goldmic gas at all." Zhou Yi made it clear, "But some media got their test report for me. From the second page, this report did not have our seal."
All the contents and data of the test report of Jinmaichi obtained by Zhou Yi are the same as those of the test report made by Tongji University for Konisonic economizer in 2008, except that the name of the sample was changed from "Konisonic economizer oil consumption" to "Jinmaichi automobile regulator economizer" and the name of the manufacturer was changed from "Shanghai Yusheng Economic and Trade Co., Ltd." to "Hong Kong Xinjiye Enterprise Group". "Our report says that once it is changed, our report will be invalid." Zhou Yi told reporters.
The reporter repeatedly called Jin Maichi's contact information on official website-China Xinjiye Holding Group Beijing Warner Baichuan Technology Co., Ltd., and the other party said that the relevant departments would reply to the reporter. However, as of press time, we have not received any response from the company.
Fuel saver "I lied to you, no discussion"
"This is definitely a scam, and it doesn't make sense in principle." Lin Jian, a senior engineer at the Automotive Engineering Development Research Institute of the Department of Automotive Engineering of Tsinghua University, told the Science and Technology Daily reporter that "the voltage of a car is stabilized by generators and voltage regulators, and it will never be stabilized by stuffing things into cigarette lighters."
"The new technology continuously developed by automobile companies can save 3% fuel. Fuel saving involves all aspects of automobiles. Starting with changing the small links of a system, it does not have much effect on fuel saving of the whole vehicle. If this equipment can really achieve the fuel-saving effect of 15%, then the car company has already adopted this equipment. " Lin Jian further explained.
"I lied to you, no discussion!" Zheng, a technician of Beijing Kuangbaotang Automobile Modification Club, blurted out. He told reporters that the generator is self-regulating, and the load of the generator will increase only when the battery is dead and high-power electrical appliances are used. A thing plugged into a cigarette lighter won't affect it.
"This kind of energy saver basically has no effect. If it was a car more than ten years ago and its working voltage was unstable, it can be stabilized by external equipment to improve the working effect and save fuel. The current car voltage is very stable, and there is no principle that voltage stabilization can save fuel. " Zheng believes.
"The economizer is not new, and now it is heavy." Lin Jian said, "When automobile EFI technology first entered China, many things were claimed to be fuel-efficient. Some claim to have energy and can access the oil circuit; Some people say that the air intake of the engine can be improved; There are more mysterious things. But in fact, the experiments we have done show that these so-called fuel-saving products are basically ineffective. Even a little impact is caused by slightly different road conditions in the test. "
Lin Jian said that many products that claim to save fuel are imported. It was popular in the United States decades ago, in Australia twenty or thirty years ago, and in Taiwan Province province 10 years ago. Now they can't fool people in those places, and there are more and more cars in the mainland, so these things are starting to have a market. (Guan Jingjing)
