Why is the low torque of large row self-priming engine not good?
It is normal that the low torque of large displacement naturally aspirated engine is not good, because this is the power output characteristic of this engine, and it needs to reach medium and high speed to output relatively large torque.
The power output characteristics of a small displacement turbocharged engine are different from those of a large displacement naturally aspirated engine.
The small-displacement turbocharged engine can output the maximum torque at a relatively low speed, which is why many consumers like this engine.
But many riders like large self-priming engines.
When the large exhaust self-priming engine reaches the high-speed area, it will give the driver a feeling of continuous power, which is very good.
When the small-displacement turbocharged engine reaches the high-speed zone, the feeling of stepping on the accelerator pedal is not very good, which is why many consumers don't like turbocharged engines.
If you haven't experienced a real large-row self-priming engine, I suggest you try it.
The large displacement naturally aspirated engine has better running smoothness and richer sound.
Even if the exhaust pipe is modified, the small-displacement turbocharged engine cannot make rich exhaust noise.
In this era, naturally aspirated engines with large displacement are becoming less and less common.
What is the charm of large displacement naturally aspirated engine?
Many riders scoff at small-displacement turbocharged engines. Although most cars are using small-displacement turbocharged engines, many riders prefer large-displacement naturally aspirated engines.
What is the special charm of large displacement naturally aspirated engine? This will tell you.
The power output mode of small displacement turbocharged engine is different from that of large displacement naturally aspirated engine.
Small-displacement turbocharged engine can output maximum torque at low speed, which is why many riders like small-displacement turbocharged engines.
But before the turbine intervention, the turbocharged engine has nothing to do with it. When the turbine intervenes, the power of the engine will suddenly explode. At this time, the driver felt that someone suddenly kicked himself behind him.
Some drivers like this feeling very much. These people find it exciting. However, some drivers don't like this feeling. These people think that the power output of small-displacement turbocharged engines is not linear enough, which will affect the driving experience and comfort.
Small displacement turbocharged engine also has a fatal disadvantage, that is, high-speed pressure drop. Generally, some small-displacement turbocharged engines will lose pressure at high speed, so most small-displacement turbocharged engines will only go when stepping on the accelerator at high speed.
The power output mode of large displacement naturally aspirated engine is just the opposite of that of small displacement turbocharged engine. This engine has low power and low torque in the low speed range. But in the middle and high speed area, this kind of engine can give drivers a continuous sense of power, which is also the biggest reason why many people like large-displacement naturally aspirated engines.
Moreover, the power output of naturally aspirated engines is more linear, and the power output of some good large-displacement naturally aspirated engines can be described as silky, which improves the driving experience, ride comfort and luxury of the car. So many people like large displacement naturally aspirated engines.
Although small-displacement turbocharged engines are being widely used, large-displacement self-priming engines will never be slaves.
