Although the actual power of the minivan is not very good, it is really possible to drive more interesting than some automatic family cars.
It's like saying: Although some people look thin and small, their strength is still quite large, you let him come to 2 barrels of mineral water, help the girl change, don't be too strong.
Most vans come with manual transmissions
The first reason minivans feel energetic is that most vans are manually operated.
Li Shaoyi of Wuhan University of Technology has a paper, "Structural Optimization Design of External Control Mechanism of Mini Car Transmission", which has been discussed.
Automobile companies will choose the corresponding transmission according to different model positioning, product needs, and market demand.
The manual transmission has the characteristics of low cost and high efficiency, and it is very suitable for the market positioning of mini cars such as mini cars such as mini cars that pay attention to cost performance and pursue low fuel consumption.
Therefore, manual transmissions are also very common in this type of car, and the application is also very extensive.
The high efficiency of the manual transmission not only saves fuel, but also means that the power is transmitted from the engine all the way to the tire, and its loss is small.
Therefore, even if the engine itself is not particularly powerful, the final performance of the power is still good.
And the manual gear shift is operated by the driver according to the actual situation, when the power is needed, it is possible to postpone the timing of this upshift, and keep the engine in the high power output speed range.
"Ah" This goes up, and the power reserve of the engine can be fully utilized.
It's like: in the past school sports day, although I didn't run very fast, every time I ran a race, I did my best to run, which may be faster than some students who didn't run at full strength.
People see you as so fat, but in order to run the 1st place, or to win the favor of the favorite girl, this is... I passed out after running. Others may just run over there easily, and who is no one is really not sure.
The van itself is light
The second reason why the minivan gives people a more violent feeling is that the van itself is lighter.
Therefore, although the general horsepower is not good, if you do not pull goods, the power-quality ratio is not bad compared with the general family car, and it is not lost.
Changhe Suzuki Big Dipper, for example, 1.4L naturally aspirated engine, the maximum output can only be 97 horsepower, 100 have not arrived, but the curb weight is only 900kg, 1 ton is not enough.
The power-to-mass ratio is 107 horsepower per ton, that is, the weight per ton of vehicle is pushed by 107 horsepower.
Take the family car for comparison, Nissan Xuanyi although the horsepower is a little stronger, but the power quality ratio is not as good as it, only 104 horsepower per ton, volkswagen Jetta VA3 only 100 horsepower per ton.
You see, the Big Dipper is still strong, so from this point of view, although the engine is weaker in horsepower, the weight of the car is lighter, and the power of the Changhe Suzuki Big Dipper is slightly better.
It's like saying: You have a lot of strength and a lot of weight, you can't do a push-up to do 2 or 3 times, like me doing sit-ups, it may not be enough.
But the light weight pull-ups, "Oops" 10, 20, 30... There's a lot to come.
Low torsion is better
The third reason why minivans feel good power is that the engine is generally targeted.
Guo Peng et al. published a paper in the journal "Small Internal Combustion Engine and Motorcycle", "The Effect of Intake Main Tube Length on the Performance of Mini Car Engines", which is discussed in it.
Urban mini-car engines commonly used in the working speed of low and medium speed, and is frequent start and stop, often waiting for traffic light intersections, right? The torque requirements for low speeds are relatively high.
Therefore, the engine will also be adjusted and optimized for the torque output of low speed accordingly.
For example, in the paper just now, it is how to optimize the length of the intake tube, even this kind of place has to use the brain, you think it is a program adjustment? The design is a brainstorming.
It allows the engine to achieve better torque output in the daily low-speed range, and bench tests and analysis are also carried out.
Come, the common Wuling Hongguang example, a well-known domestic automotive portal conducted a test of this acceleration performance.
Wuling Hongguang S1 zero hundred acceleration is 14.1s, which sounds far slower than the average family car, right?
But the maximum acceleration at the beginning can reach 0.6g, what is the concept of 0.6g? Similar to the start of the 2.0T Volkswagen Golf, 2.0T Golf.
As I said in my previous videos, the feelings of acceleration people above 0.5g are already more obvious, plus van drivers are usually hard-working, diligent, running life and doing business, right?
That is more willing to step on the accelerator than the driver of a family car, time is money, right?
If you had a chance to sit in the van, you'd find "Oh" and you'd go out, wouldn't you? Of course there's a good sense of motivation, right?
It feels good because the manual transmission is light and low twist
Therefore, in general, this feeling mainly comes from the high efficiency of the manual transmission, the focus on low-torque explosion engines and lighter bodywork, as well as the supporting vehicle design, all of which have this relationship.
Don't look down on it, this thing is really fierce, no strength, no level, how to pull goods? Right?
The power is not strong, whether it looks at the horsepower or the torque
When it comes to the power of the car, some sales when buying it say: "This car has great horsepower, good, and the power is very good." Another salesman said: "You don't listen to his blind talk, torque is the last word." ”
Since the torque is very good, why is there still horsepower to talk about? What is the point of being strong or not being strong?
All are 2.0 displacement, why do some cars look fierce? Some cars can't "meat"?
How much horsepower does a family car have to be called "enough"? Every day this sentence, buy a car is enough to use, how much in the end? I have calculated for everyone, and I have also found it for everyone, which may not be the same as what you think.
Keyword: motivation
Pay attention to my WeChat public account "spare tire said car", reply to the keyword "power", you can know immediately.
My public account, every day will give you a piece of car practical small dry goods, text, audio, video have, you pick your own convenient version on it, "spare tire said car" waiting for you to play Oh.
