The saying "You can buy self-priming but not turbines" is indeed a bit outdated for ordinary household fuel vehicles. Now, it may be more appropriate to say that "it is better to buy a turbine but not a self-priming."
is like 10 years ago. I said that I should choose a standby time for 7 days when I bought a mobile phone, which can be replaced with the battery, but it will not break even if it falls. There is no problem. Now, it is a bit strange to look at this sentence, right?
For ordinary household oil cars, this sentence is outdated.
- The advantages of self-priming themselves are no longer obvious.
Friends used to say that if you can buy self-priming, don’t buy a turbine because the turbine is not durable and has hysteresis. Now these two points have been optimized quite well. The
turbine component can basically live with the same life as the car due to the use of newer and better materials.
Beijing Institute of Technology Zhao Hongqiao has a master's thesis, "Analysis of Turbine High-cycle Fatigue Failure and Lifespan-Reliability Assessment Methods". Analyzing the microstructure changes of turbine materials on
, and found that after the simulation was used for 600,000 km, the turbine still had 85.8% reliability.
Simply put, it is: after driving 600,000 km, there is basically no problem, it is very likely that the car has been replaced by 3 units.
As for the problem of turbo hysteresis: just step on it and wait a while before leaving, this thing. Now the engines of mainstream car companies are basically optimized.
includes Mercedes-Benz , BMW , Audi , Volkswagen, Toyota , Geely , Great Wall, etc. Joint ventures, independent brands, all of which are OK, and they all use small inertia turbines.
is a bit like using a lighter and smaller paper windmill. It uses lighter force to blow the windmill, and it also makes it easier to rotate, start faster, and the hysteresis is significantly reduced.
If you don’t believe it, go test drive and take a look. We may not feel the hysteresis.
- Turbine trucks will be better driven
In addition to solving the old problems before, turbine trucks will be more powerful for transportation in cities. Let’s take Honda’s two models as an example.
Fit 1.5L naturally aspirated engine , 4600 rpm, torque 155N·m. The same Civic , 1.5T turbine engine , can output 180N·m maximum torque from 1700 to 4500 rpm.
is open in the city, but it will not be open 4 or 5000 revs all the time.
So, if the turbine is driving in the city, the advantage comes out. If you step a little, you can basically reach a better peak range and the car speeds up faster.
So, the current self-priming engine is basically the same in use compared to turbine engines, and it cannot be said that it has great advantages.
- only pursues self-priming and will miss some favorite models
At the same time, we should also note that even if we really want to choose from a priming car, it is difficult to buy it now.
Guohai Securities There is an industry research report in 2021, "The small industry of turbocharger ushers in great development", there is a data statistics in it.
Currently, the penetration rate of turbochargers has reached 50%, and due to the increase in sales of energy-saving cars and hybrid cars, it is expected that the average annual compound growth rate will reach 12% in the next few years. Don't remember
. To be honest, there are fewer and fewer naturally aspirated cars themselves, which is a bit similar to the manual transmission that many friends like. It is difficult to buy a manual transmission now.
For example, if you want to buy a priming bike, except for Toyota, Nissan , and Mazda , other brands are basically not very good at choosing. Among domestic cars, cars with a price of around 100,000 yuan are basically 1.5T engines. When buying
, you insist on choosing to aspirate naturally, and there is a possibility that you will miss the model you like.
For hybrid car , it is not necessarily
. What we mentioned earlier is pure fuel vehicles. So for hybrid cars, is there any reason for "can buy self-priming but not turbines"?
In fact, from a market perspective, in the field of hybrid vehicles, self-priming engines and turbine engines currently have a 55% share.
Shuish Shijin from the National Key Laboratory of Automotive Safety and Energy Conservation at Tsinghua University and Beijing Electric Vehicle Collaborative Innovation Center.
published a paper in the journal Journal of Automobile Safety and Energy Saving, "Outlook on the Energy Saving Technology Route for Hybrid Passenger Vehicle Engines".
said: Currently, the engines of hybrid cars are divided into naturally aspirated high-expansion ratio gasoline engine route led by Japanese car companies, and the direct injection supercharged gasoline engine route led by German car companies.
On the market, self-priming engines are used relatively more, please listen. Honda's hybrid power is basically a 2.0L self-priming engine, and Toyota uses more 1.8L naturally aspirated and 2.5L naturally aspirated. Among the domestic brands of
, BYD Qin DM-i, destroyer and other models also use naturally aspirated engines.
Recently, among the domestic brands, the newly launched Great Wall Lemon DHT and Geely Thor Hybrid use turbo engines. The engine's thermal efficiency is quite high, and the fuel consumption and power performance are also good.
So, in hybrid power, there is no obvious difference in market share between self-priming and turbines. If you plan to buy it, don’t worry too much. You can choose both of them.
Older used cars, this sentence is more suitable for
So, is there any use of the sentence "can buy self-priming but not turbines"? Some are, too.
can be used as a reference when buying a used car with relatively older age.
If the budget is tight on hand, you have to buy a used car that is more than 10 years old to carry it. If you don’t want problems often, you are even more recommended to choose a naturally aspirated model, because 10 years ago, the turbine was indeed not very mature.
I just talked about is not durable and has a lot of hysteresis. Isn’t that batch of cars just now?
10 years ago, the auto market is just the opposite of now, and naturally aspirated engines are the mainstream.
Nowadays, models such as Civic, Accord , Focus, etc., with 1.5T engines, were all 1.8L, 2.0L, and 2.4L at that time, and were all naturally aspirated engines.
So when buying a used car, choosing from self-priming may be more wise than a turbine. It is indeed a wiser choice. The models that can be selected from self-priming will be richer.
only buys ordinary household fuel vehicles. This sentence is outdated.
In general, if you only buy one ordinary household car, a gasoline car, then the sentence "can buy self-priming but not a turbine" is indeed a bit outdated. Turbines may be a better choice now.
But if you say that the car age of used cars is relatively older, for example, 6 years, 7 years, or 8 years, what I just said is still of some reference value.
Why has the automatic transmission not eliminated the manual transmission?
Now, you can buy a car naturally aspirated and turbocharged . In fact, it is a bit similar to manual transmission and automatic transmission.
. There is no need to buy a manual transmission car or a naturally aspirated car for reasons such as stability, fuel saving, etc.The key to
is to experience it yourself and use it comfortably. After all, the car is not used to transport goods, do business, or run, and 10 cents are all money, , right?
Some friends may also have doubts when they hear this: "The automatic transmission is so reliable now, so easy to use, so don't just do anything about manual transmission. What are you doing if you stay with ? "
people who are still insisting on manual transmission, What are they thinking about?
talks about a lot of natural aspiration and turbocharger. Please, from an outdated perspective, new energy is the future development direction. The country strongly supports it, and there are many good cars. Is ? Is there any manual transmission of new energy vehicle ?
- Keywords: Manual transmission
If you want to know these, follow "Spare tire talks about cars", and reply to the keyword " Manual transmission ".
will give you a piece of practical car stuff every day, has text, audio, video, , just choose the version you like, "Spare tire talks about cars" is waiting for you to play.
