Where's the fuel consumption? A few simple details of fuel-efficient driving

● Choose the correct vehicle configuration in advance.

Sharp tools make good work. It is very important to choose the appropriate configuration according to your own working conditions for truck fuel saving. For a simple example, let the fast horse of the post station go to the mill to pull the mill, and let the donkey of the mill run to the post station to deliver the letter. In this case, it is obviously not good to pull the letter. Then such a basic principle is also very suitable for truck fuel saving. This article mainly talks about the details that we are easy to ignore.

Improper use, high fuel consumption, choose the right lubricating oil.

Engine oil is the most familiar thing, and improper selection will have an impact on vehicle fuel consumption. Engine oil has the functions of cooling, lubricating, cleaning and sealing. From the simple function of lubrication, engine oil can make all the relative moving parts of the engine get good lubrication, reduce friction and reduce motion resistance. If the oil is poorly lubricated, the movement resistance will increase and the fuel consumption will also increase. In addition, the oil will slowly deteriorate after working for a long time, thus reducing viscosity, lubricating coefficient and friction. It is also important to change the oil in time.

At present, there are two misunderstandings in the use of engine oil. One is blind pursuit of high quality, and the other is excessive pursuit of low cost. In fact, neither of these behaviors is desirable. It is recommended that you choose the oil according to the requirements of the vehicle manual. In addition, with the promotion of the current national fourth product, the national fourth engine has different requirements for engine oil quality, which needs careful attention.

● Don't ignore the problem of wind resistance. The trailer also needs attention.

Nowadays, people pay more and more attention to the influence of wind resistance on automobile fuel consumption. At present, many new models in China have begun to come standard with diversion components, especially tractors and vans. This seemingly simple thing not only makes the vehicle more beautiful, but also makes the vehicle more fuel efficient. There is also the wind resistance and fuel consumption brought by high-speed window opening, which is higher than that of air conditioning, and the air conditioning with high-speed window closing can also reduce fuel consumption.

However, the problem of trailer wind resistance is often ignored. At present, the saddle position of many tractors is adjustable. Choosing the right trailer, adjusting the saddle position properly and reducing the gap between the main trailer and the trailer are helpful to reduce fuel consumption.

At present, the application of pneumatic components of trailers has been paid more and more attention. We can see the application of the trailer air guide assembly used in this Mercedes-Benz fuel consumption test. Although it has not been widely promoted in China at present, we can help reduce the fuel consumption caused by wind resistance by changing the load distribution of goods and the binding of tarpaulins.

● A journey of a thousand miles begins with the influence of a tire on fuel consumption.

As the saying goes, a journey of a thousand miles begins with a single step. For trucks, the tires are the feet, and whether the shoes are suitable or not will also have a great impact on vehicle fuel consumption. For example, when driving for a long distance, you can get a better fuel-saving experience by choosing energy-saving tires with low rolling friction. When choosing tires, we should fully consider various factors that affect fuel consumption, such as tire patterns.

In addition, the tire width will also have a certain impact on fuel consumption. The trailers used in this Mercedes-Benz fuel consumption test are all Goodyear super singletons, which have certain advantages in fuel consumption compared with the traditional twins. There is also the correct tire pressure. According to statistics, about 30% trucks have increased fuel consumption due to insufficient tire pressure when driving. I suggest you get into the habit of checking the tire pressure frequently.

● Reasonable use of instantaneous fuel consumption. Don't give up eating because of choking.

With the large-scale popularization and application of electronically controlled engines, truck instruments are also undergoing earth-shaking changes, and many of them have begun to have the function of reminding instantaneous fuel consumption. However, it is precisely this instantaneous fuel consumption that, while convenient to use, also brings some interference to drivers. Just staring at the instantaneous fuel consumption to control the vehicle is a joke.

● Cruise is not once and for all. Sometimes the human brain is more reliable than the computer.

Constant speed cruise can be said to be a breakthrough in vehicle technology. When driving on the highway for a long time, the driver does not need to control the accelerator pedal when using this function, which reduces fatigue and unnecessary speed change and can save fuel. At present, many heavy vehicles and even light trucks in China have this configuration.

● Reasonable use of auxiliary braking is not only safe but also fuel-efficient and economical.

Auxiliary braking system is becoming more and more common in heavy trucks. Aside from the hydraulic retarder, the engine braking system alone will not only be safe, but also have a certain fuel-saving effect. Because the engine brake will stop fuel injection when working downhill. In addition, it also has many advantages in reducing the wear of brake pads and tires.

However, compared with the current situation in China, although many heavy trucks are equipped with engine braking system, and even some models are equipped with engine braking system as standard, there are still many card friends who report that engine braking is not easy to use, and even worry that this equipment will damage the engine. This phenomenon is not only a waste of resources, but also a lack of pre-sales training for trucks.

● Predicting driving is very important. Remember the three-second rule.

Seeing from all directions, listening from all directions, these eight words sound very simple, and everyone understands the truth, but it is very difficult to do in practice. Here we briefly talk about predictive driving. In the eyes of drivers, some people can see the range of 300 meters or more, while others can only see the taillights of the front car and the rear car. Some people use fart cars, others use their brains to drive. It sounds vulgar, because it involves predictive driving.

Low fuel-efficient driving strategy, haste makes waste, groping for.

For example, under the same road conditions, two cars travel at 80 km/h and 90 km/h 100 km respectively. The car with 90km/h is only 7 minutes faster than the car with 80km/h, but the fuel consumption will be different by 10%. On the contrary, the two cars are traveling at 40km/h and 50km/h 100 km respectively under high-speed road conditions. A 40 km/h car will be 30 minutes slower than a 50 km/h car, but the fuel consumption is not much different.

This is also the most profound experience of following the car at the scene. When climbing a road section, it is necessary to accelerate the vehicle in advance through foresight, so that the vehicle can rush uphill as quickly as possible at high-grade and low speed, and the straight road section can drive at a relatively stable speed, so that fuel consumption and timeliness can be well expressed. At present, the habit of many card friends is to climb slowly at low speed and high speed when encountering a slope, and run hard at high speed when encountering a flat road. The fuel consumption gap caused by these two driving habits is very large. How to balance this needs to be explored constantly in driving. Through the pressure difference inside the magic capsule, the process of fuel atomization can be accelerated, so that it can be atomized in advance and the combustion is more complete. After the magic capsule is installed, the most intuitive effect is that the fuel burns fully, effectively reducing pollutant emissions, purifying tail gas and reducing engine carbon deposition.
