Driving fuel-saving tips

I believe that the majority of driving friends are worrying about the high price of oil! Today Xiaobian brings you a little trick to drive fuel.

The most fuel-efficient way to drive a car is what many people often talk about. The ideal fuel consumption announced by the depot is always based on the results obtained when driving at a constant speed; the old driver from the carburetor to the EFI always considers that the neutral position is the most fuel-efficient; the new voice says that the use of gears Sliding instead of neutral is a more economical method; others say that now that engine technology is advanced, high-speed engines are not necessarily very fuel-consuming... All kinds of arguments are inconsistent, so we planned a special experiment to drive the public Kadi into the darkness once more. Solve all mysteries with practice and numbers.

Endurance Journey Cadiz used for this test is a very suitable prop. As a working vehicle, fuel economy is an important selling point. Like the Fit fuel-efficient game, this test was selected in the middle of the night when the traffic volume was relatively small, and was carried out on the ring road with the least traffic lights. In order to imitate the daily operating conditions, considering that we are driving a work vehicle, we have added 14 boxes of “car guides” to its boot and have a total weight of 260 kg. It's a good thing. Fourteen magazines are easy to load. There's no shortage of strength at the start. After using the leaf spring suspension, the Caddy bounces more when empty, but with more than two hundred kilograms plus the weight of two adults, the total weight of the whole vehicle exceeds two tons. The leaf spring shows its strong bearing. force.

We use the four methods described above to test. Each round took about one and a half hours, so four rounds down, a total of more than 400 kilometers, the day has also been bright. Don't stick your tongue out. Whoever calls the "Car Herald" is a bunch of guys who can't do without the throttle?

The first simulation of cruise control and high-speed travel is the test method of the factory data. That is, try to keep driving at a constant speed at a constant speed. Kaidi's cruise control system provides great convenience for accurate testing. When the speedometer is pointing at 80km/h, it starts cruising, and the tachometer pointer stops at about 2700rpm. The cabin is quiet and comfortable, and it almost feels that the computer evenly delivers the gasoline with enough accuracy into the cylinder. It took 110km to run in 1 hour and 39 minutes and consumed 7.6L of fuel.

The following rounds of tests are based on this time, in order to achieve a similar average speed. Kaidi is a working vehicle. We must pay attention to efficiency. It is impossible to use time to exchange fuel economy.

The second round is the high rotation test. The speed is still maintained at 80km/h, but with the 4th gear, it is maintained at 3000-3500rpm. One of the benefits of high-speed driving is that the car will have better power. Volkswagen's engine's low-twist performance has been relatively flat, and Kadiko's high turn gives a more spiritual feeling. However, the refreshing power comes at a price, which is the 9.6L fuel consumption result. Today's engine technology is naturally not the same, and it will not be a problem to cope with the long-term high-speed operation, but the fuel consumption it brings is still not low.

Neutral? Drag?

The third return is a neutral coast test. This is a traditional fuel-saving method, which will increase the speed of the vehicle and then remove the gear to let the inertia move forward with the car. When the speed is reduced to a certain level, it will be re-arranged and accelerated. The hand-held Caddy makes this kind of movement very easy, without the slightest labor intensity. To be honest, it's very relaxing to let go of a stop-and-go vehicle. It's just for safety. But the result of this method is really good: Only 7.3L of oil was added.

The last item is gear-stop taxiing. This is a new fuel-saving method after the emergence of EFIs, especially among taxi drivers. Also add some oil and let go of the throttle to allow the car to slide, but the car always catches the block during taxiing. The fuel-saving rationale of this method is that the computer sets the fuel injection amount to zero when dragging on the gear, and if there is a neutral gear, the engine has idle fuel consumption. However, after a round of driving, the result of 8.7L surprised us all.

In principle, when the neutral gear is in neutral, the vehicle coasts completely; on the contrary, there is a power link between the engine and the drive system and the drive wheel when the gears of the gearbox are engaged. The drive wheel slows the speed of the speed drop, and the slowly falling speed slows down. The speed of the car, so the engine oil consumption is zero during the taxi, the distance to taxi is greatly reduced. In addition, the increased load that we put on the car also increases the inertia of the car, increases the distance of the neutral coast, but adds to the burden on the engine when the power is connected, making the difference between the two more than our estimate.

According to the test results, Kaidi can indeed use energy conservation as one of its selling points. In the first round of the most fuel-efficient operation, the fuel consumption converted to 100 kilometers is only 6.63 liters, and this is the result with a load of over 300 kilograms. . The 101hp horsepower needed to make this car run faster on the road, but the fuel consumption level shown under heavy load was indeed satisfactory.

As for the comparison of methods, it can be seen that the lowest fuel consumption figures are still obtained with the oldest air gap method, but it is well known that safety is compromised when coasting; and today, as more and more automatic cars are used, this method does not reality. As can be seen from the data, the difference between the fuel consumption of a constant speed and the lowest value of a neutral taxi is only 0.3 litres/hundred kilometers, and it is obviously not worth paying a safe price for these slight gaps. Therefore, we believe that the best way to save fuel is to mimic the way of cruise control, keep the speed and speed as steady as possible, and use the most uniform and subtle power to continue to step on the throttle.

The above is the driving skill brought to you today. You may wish to check the use of these tips when driving.
