Volkswagen was the first manufacturer to commercialize turbocharged engines on a large scale. In the early days, Volkswagen was under considerable pressure. After all, at that time, Volkswagen's turbocharged engines often had problems, including "burning engine oil". But time has proven that Volkswagen's move at the time was very successful.
Because the current automobile market has long been dominated by turbocharged engines, and even a considerable number of consumers say that Volkswagen's 14T engine is better than many 20L or even better. The 25-liter naturally aspirated engine is stronger, but is it really? Today we are going to talk about this topic.
Driving in the city, the speed is within 80 per hour, the throttle response is self-priming, the foot feeling is very good, you can step on it as much as you want, and it is very comfortable. Mostly stop-and-go, following cars. More comfortable than turbocharging. The turbine has good high-speed performance. This can be more controversial. The high-speed performance I want to express is not who is better than whom.
Scenario assumptions, for example, are cruising at 120 mph on a highway. Although the speed limit is 120 mph, my speed is reduced to 135-140 mph when I overtake. After a while, it regains its cruising speed. During this period of acceleration, self-priming, let alone floor oil, is no longer effective even at 4000 rpm.
The feeling inside the car is bad, the engine roars, and overtaking is slow at low speeds. It is very oily and must be carefully maintained. Think about the psychology of car passengers. In fact, you just want to overtake another car quickly. Others think you're jogging with your family. Do you feel about this? Not to mention self-priming 20.
But for a turbo car, whether it's 14t or 15t, try increasing the revs from 120 to 140 and then press the throttle deeply. When the speed is lower than 3000, the power increases. There is no overtaking or noise in the car, and overtaking makes people feel comfortable. It feels good! And high-speed cruising is more fuel-efficient than 25.
For daily low-speed driving, the self-aspirated engine model is more "stable", some people may say that the 14T Magotan 0-100 acceleration in 86 seconds, faster than the 20L gasoline version of the Accord. The maximum torque is also higher, and the power delivery should be perfect, but in fact it is not. When driving at low and medium speeds in daily life, one of the most important indicators is to drive well and "follow the foot".
The power is always available, the car responds to the speed change in time, the speed can be adjusted very finely, and the power output is smooth, this point, if it is a 20L Accord and a 25L Camry, it is well adjusted, but the 14T Magotan because its basic displacement is too small, the gearbox dual-clutch is used, and it is good when driving smoothly at low speeds.
But when encountering slightly higher speeds. When they change some of the required rpm, the engine usually climbs to around 2000 before it can be used. It shows the performance of "pressing the accelerator lightly without pulling it open, but when you press the pedal deeply to a certain position, the power suddenly explodes". 1 3 after a sudden flashpoint. Therefore, it is not easy to control the throttle and speed precisely.
Parking and following the car are more tiring, and in addition, reversing often requires the coordination of accelerator and brake, which is also very inconvenient. Power = (torque * speed) 9550, this formula is very important. In simple terms, power is actually the product of torque and speed. From this formula we can see.
Power (power at a given time, not limited power) and torque are actually the same thing! When the speed is the same: who has more torque, more power, and more acceleration (this derivation is the origin of the current saying that torque determines acceleration, it can't be wrong, it can only be said that it is not rigorous)! In the case of the same torque: whoever has the highest rev will have more power and acceleration.
This derivation explains why the torque limit of many large-displacement self-priming vehicles is not as good as 20t, but 01. It's also better than 20. the reason for the high speed of the T-car; Because the revs are good enough, although the engine torque is insufficient, if the revs can be increased by a thousand rpm, it is actually enough.
Because speed is measured in thousands, and the difference in torque is only a few tens of Nm at most! Based on these two derivation steps, we can really understand whether Volkswagen's 14T engine is better than 20L and 25L; What are the highlights of the 14t machine? The highlight is that the peak torque is large and the peak torque comes early!
