Turning on the air conditioner in summer really affects the power of the car. But different cars have different degrees of influence. It's like the exam questions become more difficult, and the top students should take as many exams as possible. But the students who are a little worse, originally 60 points, are now 55, failing.
How does air conditioning affect power?
The air conditioning of that car is independent. In other words, some energy needs to be separated from the engine to achieve the purpose of refrigeration. As soon as the air conditioner is turned on and the compressor turns, the power of the engine moves a little, and the power transmitted to the tires is small.
It's like I bought a hand-grabbed cake with 10 yuan, so I can have a good meal. But mom called suddenly, and she said, "Well," she brought a bottle of coke. Well, I only have seven dollars. You can't add tenderloin today, and adding eggs is probably not enough.
The smaller the displacement, the worse the power and the greater the impact.
Therefore, it has a great influence on the air conditioning of cars with small displacement and poor power. You can feel it when you speed up the climb. Taking the test data in the paper as a reference: 1 vehicle matching 1.5L naturally aspirated, and the output power of 1500 rpm is only13.3kw.. The loss caused by air conditioning is 2.6kW. That consumption is 19.5%, and the 20% discount is gone. So if you can't turn on the air conditioner, the difference is really obvious.
For the same displacement, the influence of turbocharging is generally less than that of self-priming. Those are all small displacement, and some friends drive turbo cars. The influence of air conditioning is less than that of natural inhalation. Because small-displacement turbocars now use low-inertia turbines.
You can understand that this fan blade is lighter and better. Friends who like to install computers, go and see the owl fan. At that low speed, the turbine works and the engine output is very strong.
For example, Chevrolet Explorer's 1.5T engine, 1500 rpm, 70kW output and 220Nm torque. Then your air conditioner uses 3kW and 4kW, which are basically negligible.
What if the motivation is affected?
Well, if we just turn on the small displacement, naturally inhale. I usually turn on the air conditioner and feel a little fleshy and uncomfortable. What should I do? In fact, most cars have enough power reserves as long as they step on the accelerator more.
Air conditioning has a serious impact, at most in the low speed range.
What do you want? Overtake, speed up and step on the accelerator a little deeper. For example, LaVida 1.5L naturally inhales. 1000 rpm, power only 28kW, torque 1 10Nm. But at 3800 rpm, there is a peak torque of 150Nm. As soon as you speed up, the influence of air conditioning on power immediately comes down.
