Why is a three-cylinder engine a technological retrogression?
Everyone thinks that the 3-cylinder engine is a step backwards, mainly because the 3-cylinder engine is not a new technology, and it is really not as good as the 4-cylinder engine. This is like: In the past, 10 yuan could buy four salted eggs, but now 10 yuan: "Sorry, three eggs, but the salt pays for itself." "Huh?" Right?

Cylinder 3 was not introduced in recent years.

First of all, the three-cylinder engine is not a new technology developed in recent years and has a long history. As early as the last century, Subaru's Justy, Saab 9-3 and Alfa Romeo 33 all had a glorious three-cylinder history. Li Xia was produced by us in 1980s and 1990s, equipped with a three-cylinder engine code-named "TJ376Q". At the same time, Alto in that era used F8B engine, which was also a three-cylinder engine.

Later, due to congenital defects such as noise and jitter, the 3-cylinder engine began to be gradually abandoned by car companies. Although the current 3 cylinders are much more advanced than before, it will inevitably make people feel: Hey, are you ... is this retro? Or reform? Or what? It has been rebuilt, reset version, right? HD 4K reset versions are all here, aren't they? Do you think it's a technological retrogression?

It has always been the pursuit of more cylinders and greater displacement.

At the same time, everyone has been pursuing that the more cylinders, the greater the displacement, the better. Using three cylinders is the opposite direction. Of course I feel, "Did I lose?"

Feng's paper was published in China Science and Education Innovation Herald, discussing China's immature automobile culture. It says: When people buy a car in China, they like to regard buying a car with a small displacement as an act of losing value. They think that the greater the displacement, the more cylinders, the higher the face and value. After using three cylinders, the number of cylinders is less. Compared with four cylinders, the displacement is getting smaller and smaller. Needless to say, technology is declining. I feel ... my value is also declining, and I buy less things at the same price.

Three cylinders are not as good as four.

In addition, in actual use, the experience of three-cylinder machine is really not as good as that of four-cylinder machine. Similarly, it will also strengthen the cognition of "feeling that technology has regressed".

Cylinder 3 doesn't save much oil when used.

Fuel consumption, right? Many people think that with fewer cylinders, the fuel consumption will always be lower, right? One tank is missing. But in fact, the fuel consumption has decreased, but it is really minimal. The paper "Development and Optimization of NVH for Turbocharged Direct Injection Three-cylinder Gasoline Engine" published by Shen Yuan and others in the magazine "Automobile Safety and Energy Saving". It says: With the same engine displacement, the 3-cylinder engine is lighter and has less friction loss, which can save about 10% gasoline.

Sounds "gee, not bad", doesn't it? However, judging from the actual use of our car owners, the degree of fuel consumption reduction of three-cylinder engines is not so great. For example, the average fuel consumption of Civic 3-cylinder version is 7. 13L/ 100km, while that of Civic 4-cylinder version is 7.47L/ 100km, which has not decreased by 5%. Converted into money, opening 100km will probably save 2 yuan 30 points.

Experience is not as good as 4 cylinders.

This little reduction in fuel consumption is at the expense of experience. As we have said in the video before, the 3-cylinder engine may have poor coherence, some models will shake, some models will have noise, and some models will have problems such as high-speed power attenuation.

Take jitter as an example: the ignition interval of a three-cylinder engine is 240, even if the internal interaction force can be balanced, it cannot be balanced in the direction of force. It's a bit like: your washing machine at home, think about it, when it is dehydrated, does it hum like this? This is actually unstable, isn't it?

This is the shake, but the washing machine you put in the car. Of course, this is a bit exaggerated and everyone can understand it. Even if the current manufacturers use eccentric mass flywheel, balance shaft and other methods to optimize, but this "buzz" is just not as big as before, right?

It can even be similar to a four-cylinder car, but there are still some concerns about its long-term effectiveness. For example, in terms of isolation jitter, the level of manufacturers is uneven, some are doing better, and some are called "average". Anyway, I just think that the 3-cylinder machine may be similar to the 4-cylinder machine, but I feel uncomfortable just listening to it, what's more, sometimes it's really not as good as the 4-cylinder machine, right?

The advantages of 3 cylinders are not concerned by consumers.

Why use a three-cylinder machine? Three-cylinder machine certainly still has the benefits of three-cylinder machine, but most of the benefits and advantages of three-cylinder machine are not concerned by our consumers. According to the "20 19 China Automobile Consumption Trend Report" jointly released by Huge Engine, the main factors that automobile consumers consider when buying a car are appearance, safety, price, configuration and brand.

To put it bluntly, the advantage of "three-cylinder machine is relatively more environmentally friendly" is not at the forefront when our consumers buy a car, and even some friends completely ignore it. Just like: You only know that Houttuynia cordata is bitter and doesn't taste good, but you don't know that Houttuynia cordata has antibacterial, anti-inflammatory, disinfection and diuretic functions. Anyway: "Hey, what have I not eaten with Houttuynia cordata?"

3-cylinder is not a new technology, and the experience is not as good as 4-cylinder.

Generally speaking, people think that the three-cylinder engine is a retrogression. On the one hand, it is not a new technology, and it has long been eliminated. I brought back the HD reset version for you. I feel uncomfortable both psychologically and cognitively. On the other hand, a three-cylinder engine saves fuel, but it saves less fuel. In the case of not saving much, the car is louder and more rocking.

Driving a car with 1.5 million feels like 1.2 million, and it feels like 1 10,000. Don't I lose money? Experience is not as good as 4 cylinders. Coupled with environmental protection: "Oh, look at the brand first, look at the configuration first. Environmental protection is not in front of that. " Some friends haven't decided yet. "Business people." Wait a minute.
