Hello everyone, I'm Xiao Li. Many people usually don't care much about fuel consumption when driving, but now that the price of oil is getting higher and higher, they are starting to care more and more about the fuel consumption of their cars. Just started to study how to drive more fuel-efficient, just like my friend, I always knew that the fuel consumption of driving on the highway would be relatively low, but I didn't notice the problem that the fuel consumption of driving on the highway will be higher and higher, and I have been driving for 12 years, and now the fuel is expensive, I learned the skills of driving on the highway to save fuel.
In fact, when driving in the urban area, no matter how high the thermal efficiency of the engine is, it is useless, the speed is too slow and the performance of the stop-and-go engine can not be played at all, the thermal efficiency of 40% of the car, generally can play 15% to 20% of the engine, so the fuel consumption of urban driving is very high. But many people say that the fuel consumption of driving on the highway is lower, that is not to know what others say and follow it, some cars on the highway after the need to master the skills to reduce fuel consumption, otherwise the faster the speed, the more fuel is consumed. For some large displacement cars, the performance of the engine can only be exerted after the high speed, so the fuel consumption will be lower, but for some small displacement cars, as long as it exceeds its economic speed, the faster the fuel consumption of the car, if you do not know how to master some fuel-saving skills, then the fuel consumption of you driving on the highway is not low on the national highway.
- The throttle is more fuel-efficient when you press and loosen it
When driving at high speeds, you can also reduce fuel consumption by pressing and loosening the accelerator, but many people don't know how to operate it. It is not difficult to find that the characteristics of these two functions are to achieve the purpose of fuel saving by keeping the car at a constant speed as much as possible, and in the process of constant speed, as long as you do not step on the brakes and do not step on the accelerator, it will not automatically exit, and the fuel consumption in the process of fixed speed is relatively low. Therefore, in the process of driving at high speed, we should step on the brakes as little as possible, and use the accelerator pedal to control the speed as much as possible, so as to achieve the purpose of fuel saving.
In the process of driving on the high speed, don't accelerate the floor oil as soon as you see the gap, otherwise you will find that just after accelerating, because there is a car in front of you to slow down, you need to brake to slow down, so that the oil burned will cancel out the friction of the brake. We must learn to observe the quotations and predict the movement of the car in front, just like we go to the market to set up a stall, we must learn to predict that it is the students and uncles and aunts who will go out to shop tonight, and it is easy to sell the goods in a targeted manner. Seeing that the road conditions in front are better, we must know in our hearts, after I step on the accelerator to accelerate, under what circumstances do I need to throw off the accelerator in advance to let the car slow down naturally, how much time in advance to throw off the accelerator in order to maintain a safe distance from the car in front of me without stepping on the brakes, which is within the range of prediction.
For example, if the front car in front is empty, most of the car in front will maintain a constant speed for a long time after accelerating, and at this time we can accelerate to keep up with the same speed. But there are a bunch of cars in front of the car in front, but he suddenly accelerates, then he must accelerate to overtake, if you accelerate to keep up, you will soon step on the brakes, which is a waste of fuel. Learning to predict is the premise of learning the fuel-saving technique of stepping on the accelerator and releasing it.
- Maintaining a reasonable speed is more fuel-efficient
After the current new energy vehicles are on the high-speed, we all know that it is the most energy-efficient to maintain a speed of about 100, right? But on the highway to judge the emergency speed of the method is not the same as our national highway shell, the national highway you can drive about 60 speed, it is already considered the economic speed to arrive, but on the highway, you press 60 to drive, that is not a moving roadblock? The method of judging the economic speed of the vehicle on the highway is to look at the speed of the engine, the higher the speed, the more fuel is consumed.
Whether it is a self-aspirated car or a car with T, there is a speed at maximum power, such as the Vios I drove before, the speed at maximum power is 6600 rpm, but we, if we really step on 6600 rpm, the fuel consumption of the engine will be absolutely high. The most fuel-efficient speed at high speed is the speed at which the engine outputs one-third of its power, and the corresponding speed at this speed is the most fuel-efficient speed. For example, the Vios I drove myself, when it was about 2200 to 2500 rpm, the speed of the car reached more than 100, and the fuel consumption at this time was relatively low, but if I drove to 120, the engine speed would increase by more than 1,000 rpm, and it would come directly to more than 3500, and the fuel consumption at this time would be relatively large.
Like the Toyota 2.5 Camry, the speed reaches 120 at 1800 rpm, but the fuel consumption of this kind of car can reach 5 to 6 liters when driving at a speed of 120, which is relatively low. The speed of 1800 rpm is about one-third of 5600 rpm. Therefore, when we drive on the high speed and control the speed at one-third of the speed at the maximum power output, the corresponding speed is the most fuel-efficient, which fully meets the speed limit requirements on the highway, and it will not be a turtle speed, but the fuel consumption is indeed the most ideal electricity bill.
The above are the 2 tips for driving on the highway to save fuel, and novices learn not to suffer. If you think what I said is helpful to you, don't forget to give me a thumbs up and thank you.
