The economic fuel consumption of each car is not the same, sometimes watching other people's cars run 100km/h is the most fuel-efficient, but their own car running 100km/h is incomparably fuel-intensive, so today's knowledge point is how to measure your lowest fuel consumption with a trick.
Let's start with the results and practices:
The minimum speed in the highest gear must be the engine state with the lowest technical fuel consumption, be sure to put your gearbox in the highest gear, and then start to drive down, when the gearbox starts to downshift, remember this speed, and then gently press some throttle.
Remember, this state is the lowest fuel consumption.
For example, if you are driving a 6AT automatic car, at a speed of 60km/h and the engine starts to drop to 5 gears at 1500 rpm, then you need to gently increase the speed, which is the best fuel consumption of your car.
At this time, it is necessary to pay attention, because the road conditions are not a single highway or country road, so at this time I am not talking about "speed" and "speed", but the state of the vehicle.
Because if you encounter a ramp with a very long uphill, then the speed and speed will definitely be affected, be sure to remember the lowest speed of the engine in the highest gear, this big principle is unchanged.
Generally speaking, the best economic speed of the car with a slightly larger displacement will be higher, but basically it will not exceed 80km/h, such as the old crown car, the economic speed of 70km/h is the most comfortable, on the one hand, the gearbox is not much, the fast transmission takes the lead in reaching the gear limit, and the speed needs to increase the engine speed and output more power.
The same is the 6th gear, your speed is 3000 rpm, my speed is 1500 rpm, the same time you do more work than I do, naturally need more fuel. Often the result is that for a long time you run down 9L fuel consumption, I run down 7L fuel consumption.
The economic speed of the car with a larger displacement will be higher, because the displacement is large, the number of cylinders is large, the best economic speed is 1500 rpm, and the more work is done, so the faster the car runs.
On the contrary, the 1.0L van because of the small engine displacement, small cylinder capacity, do the reason for weak functional force, once hung to 5 gears, if the speed is controlled at 1500 rpm, it is possible that the speed is 40km/h, in fact, for the van, the economic speed is really only around 40-50km/h.
So what we see is that the most suitable road condition for vans is the provincial road, and running at a uniform speed of 50km/h is really incredible. But for a car like the Range Rover, running 90km/h on the far right of the highway can also find its own economic fuel consumption.
In fact, we can see the vast majority of family cars, the speed of 90km/h has put the engine in a crazy output workmanship state, will not give you a very fuel-efficient feedback.
The most opened in this period is the EA888, a high-powered volkswagen 2.0T engine.
The best economic fuel consumption of this car is about 65km/h, 7 gears, the speed control at about 1500 rpm can run out of about 6.5L fuel consumption, but at a high speed of 100km/h, fuel consumption can be as high as about 8.5L.
If most highways in your city have a speed limit of 100km/h, you can try it at 90km/h, and be sure to be more comfortable than running 100km/h.
