As we all know, in the vast number of truck users, the truck has another name - "oil tiger." Nowadays, with the continuous rise of domestic oil prices, how to make “oil tigers†no longer have bloody mouths at all times, it has become the most concern for truck users. After a period of investigation, the Fangde.com reporter found that for fuel-efficient, the majority of truck users gave three answers: relying on the engine, relying on vehicles, and relying on driving technology. So what is the most effective fuel saving method in today's form?
â— Â Traditional fuel economy: rely on engines, vehicles
In a large logistics market in Beijing, the reporter encountered a lot of drivers. For the reporter's question “What do you think is the most important fuel-efficient truck?â€, the answer given by most truck drivers is: rely on the engine and the vehicle. Master Wang and Master Li are two of them.
According to Master Wang, he used to use trucks from many domestic brands. “I used to buy cars to look at the brand, because at that time, the money was relatively cheap, and the focus on buying a car was durable; but now I’m buying a car, with domestic oil prices. The rise, like many people, I began to focus on fuel consumption." Referring to fuel consumption, Master Wang said that he is most concerned about the engine. "The engine is the heart of the entire vehicle. The quality of the vehicle, that is, the level of fuel consumption, is of course reflected through the heart."
Unlike Master Wang, Master Li believes that the configuration of the vehicle is the key to fuel economy. "Mainly the vehicle configuration, engine horsepower, transmission and rear axle ratio, these are the most important. The configuration of the vehicle is not reasonable, for example, the high-powered engine pulls a small-tonnage vehicle, or the small-horsepower engine pulls a large tonnage. Vehicles will be very costly.†Therefore, according to Master Li, vehicles must have a more scientific configuration in order to achieve a good fuel economy.
However, the reporter's investigation also found that neither the engine nor the vehicle is considered to achieve a good fuel-saving effect.
“The domestic engine brand,†said Master Wang, sighed. “I used almost all of them, but I still didn’t find brands that made me more satisfied.†For reasons, Master Wang analyzed, “Not dissatisfied, correct. That said, it should only make me satisfied for some time, because after this time, all engine brands will gradually increase their fuel consumption. For example, my car often pulls 30 tons of cargo, at the beginning, The engine oil consumption can be maintained at about 34L per 100 kilometers, but after a period of time, it will be as high as 37~38L and sometimes even 40L."
In the same way, Master Li, who values ​​the vehicle configuration, is not very satisfied with the fuel-saving effect of his vehicles. "Will be right, it cannot be denied that some vehicle allocation technologies cannot be achieved by domestic truck companies. Therefore, compared with foreign vehicles, there are still some gaps in the fuel efficiency of domestic trucks."
â— Â High-end fuel economy: good driving habits
So, as they say, if you drive a domestic truck, you can't achieve a good fuel economy? The answer, obviously, is negative. Why do they not get a good fuel economy? Today, what is the more "high-end" fuel-efficient way?
“To make drivers develop good driving habits,†said a logistics owner in Shanghai, “The same 30 tons of cargo, so that different drivers transport, there are different fuel consumption data, and this data gap can be as large as about 10% Later, after we had allowed these drivers with good driving skills to follow up and guide the drivers who had high fuel consumption for a period of time, our company's fuel consumption level was reduced by a fairly low level, like our driver is now transporting 30 tons of fuel. Goods, fuel consumption per 100 kilometers can be reduced to below 33L." Visible, good driving habits, have a great help to reduce fuel consumption.
Similarly, a domestic heavy truck brand technical staff also said that the decisive role of fuel economy in addition to the performance of the car itself, the driver's driving habits are also very important. “If you control the speed and engine speed within the economic range, not only the power output of the vehicle is strong, but also the most economical fuel consumption can be obtained. For example, on an uphill slope, some drivers are accustomed to stepping the throttle down to a speed of 2800. Turning to the above, it sounds like the engine is very "rigid". In fact, the climbing power of the vehicle is reduced, but the fuel consumption will be doubled.
If the engine speed is controlled within the economical speed range, a greater climbing force can be obtained. This is the basic reason why some drivers report that some cars are erratic on slopes and the slopes are high in fuel consumption. In addition, he also believes that when the engine speed exceeds the economic speed zone when adding and subtracting gear, you must select the best shift point; in the premise of adapting to traffic conditions, as far as possible safe and uniform driving, repeated acceleration or deceleration, fuel consumption will There is a clear increase.
In addition, the data from the truck fuel-saving competition that is held every year in the country can also provide a good illustration of this point. It is reported that this domestic truck company has almost participated in the fuel-saving competition, the final results show that the same tonnage of the models, the domestic fuel consumption of various companies, the gap is only about 5%, in recent years, this gap has been reduced The smaller, but the same model of the game, the difference in fuel consumption of different players may reach 10% or more.
Therefore, it is not difficult to see that good driving habits are the most effective fuel-saving methods today when the quality of vehicles is comparable.
Foreign truck companies seem to have noticed this very early. According to statistics, although truck companies in foreign countries have advanced products, they also attach great importance to fuel economy. Volvo and Scania still hold competitions for fuel-saving driving every year. In addition to the energy saving of the products themselves, they attach importance to people. , that is, the role of drivers in fuel conservation.
