For most car owners, testing their own vehicles with a horsepower machine may not be realistic. After all, most people buy a car for daily commuting or traveling with the whole family. However, as more and more horsepower machine tests appear on the Internet, it still arouses the curiosity of many people. For example, some time ago, a certain company conducted a huge luxury brand SUV horsepower machine test, and even generated a great response online.
After all, as long as it was about a certain manufacturer’s engine false mark, there would be a lot of noise on the Internet. Besides, who doesn’t want to know the true level of the power of the car they drive, but testing with their own car must be distressed. It doesn't matter if someone else tests it. But there is a peculiar phenomenon in the entire industry, that is, as long as there is a horsepower machine test result, there is absolutely a bunch of people around certain auto manufacturers spraying their engine virtual standards, as if this has become the unspoken rule of the industry?
Why does the horsepower engine test often lead to the controversy of engine false standard?
According to the results of a previous test, it can be said that the agreement between the test data on the horsepower machine and the nominal power exceeds 90%. However, the agreement between the nominal power and actual power of most models is about 80%. In the face of this situation, most people generally understand that it may belong to the virtual engine standard, but it is not.
So the question is, what is the engine virtual standard? In fact, many people don't even know the total power of the engine and the net power of . What do these conceptual names mean? Generally speaking, the engine has two terms: total power and net power. In fact, this is easy to understand, because in addition to the engine itself, it also has accessories that consume energy such as radiators, exhaust systems, and fans. If these accessory configurations are removed, what remains is the total power, which is what we often call the rated power.
Of course, this is only an ideal state, because in fact the engine cannot do without radiator, exhaust system, fan, etc., and these accessories all need to consume the power of the engine.Therefore, add these power consumption, that is the net power of the engine. It is not difficult to see that the net power is definitely smaller than the total power. And sometimes, we see some models on the Internet that publicize the total power, so the data must be better than the actual data, but after the test, it is prone to false standards. So, can you say that this is a virtual engine standard? Let's go on.
If you want to know the net power of your vehicle, you can directly check the data on the vehicle nameplate. Here, we think it is necessary to emphasize that, in general, if automakers dare to declare the power to the Ministry of Industry and Information Technology or mark it on the nameplate, it is basically unlikely that there will be false engine bids. Because, if a manufacturer dares to arbitrarily mark this power, it involves false propaganda, and the most serious may face a penalty of one compensation for three. If you think about it with your toes, you should know, which car manufacturer is so stupid and puts such an obvious loophole for you to catch? However, some auto media just show off their cleverness, mislead consumers, and directly disrupt the atmosphere of the entire industry. It can be described as "a mouse shit makes a pot of soup!"
The virtual engine standard is inseparable Individual self-media guides
indiscriminately. In fact, in our opinion, some auto self-media opened their mouths and said that the car manufacturer’s engine is imaginary, and shutting up is the auto manufacturer’s engine. But in fact, I have no idea why the engine power advertised by the manufacturer is different from the actual test power, and this is precisely a "touchstone" that can test whether the car's self-media is professional.
In the past, when some national models were declared, most of the total power was declared, but the net power was only declared after the later standards were revised. And some self-media do not know the historical situation, and often just look at the test results of the horsepower machine and directly start the spray. What is the difference between such a self-media and the "keyboard man" who don't understand anything on the Internet?
Of course, there are some special situations. Some automakers haveIt is also the total power that is often advertised to the outside world, so there will be occasional rollovers. But if you want to say whether it is a false bid or not, then you still have to look at the net power of the engine seen on the application information of the Ministry of Industry and Information Technology or on the nameplate. As long as there is no fraud, there is no such thing as a false standard according to the engine power data obtained by the GBT 19055-2003 standard test.
Of course, there are still some people who cannot reach the manufacturer's nominal net power when testing on a horsepower machine. What is going on? In fact, this is not difficult to understand. After all, the various test data provided by the manufacturer are in an ideal state, or in a laboratory environment, the environmental conditions are quite harsh. This is actually similar to the mobile phone test. For example, the official running scores, which ordinary users can't run on their own, are actually for similar reasons. The car side is more complicated.
For example, when testing engine power, because there is no mention of oil product differences, after all, different oil products have a considerable impact on the final result. For example, if there are two different engines with the same net power, one with No. 95 oil and the other with No. 92 oil, the oil will definitely affect the power performance under high load. But it might be more intuitive if you change to one oil.
In addition, as far as we know, the horsepower testing methods in different regions are also different. For example, Japan uses the JIS standard, the United States uses the SAE standard, Germany uses the DIN standard, and there is an ISO international standard. These standards themselves are also different. For example, the ISO standard for intake air temperature is 25°C, while the DIN standard is 20°C, but the difference of 5°C is also crucial to the impact of turbocharged engines. In addition, the on-wheel transmission efficiency is actually mainly related to the gearbox type and adjustment, which is easier to understand. This is like ZF gearbox, why is Land Rover inferior to BMW.
So if you don’t figure out the theoretical knowledge points, you’ll just follow the rhythm. Some auto media have either kneel down for too long.Can't stand up; otherwise, I'm willing to line up with "Keyboard Man", squirting and rhythmic.
is written at the end
In our opinion, it doesn’t make much sense to test a car model driven by ordinary people with a horsepower machine. You don’t get off the track, right? If it's some performance cars, it's still quite a gimmick to test, and then some luxury cars. Ordinary cars are generally sufficient to measure the maximum horsepower on the wheels and the actual transmission efficiency. In fact, whether they run fast or not has much to do with family cars.
So, for those self-media who are okay to tune in and talk about the false engine standard of auto manufacturers at every turn, we have to advise, "If there is no evidence, it is a price to spread rumors!" If it is really a false engine power standard, then it is natural. Relevant agencies and departments will punish the car manufacturers involved. But if there is no problem with the power on the nameplate, the unscrupulous self-media people who want to get the attention of people and attract traffic, just wait to receive the lawyer's letter from the manufacturer!
