The National Development and Reform Commission recently announced that since 24:00 on the 11th, domestic gasoline and diesel prices have risen by 120 yuan and 115 yuan per ton, respectively. This is the second consecutive increase in the price of gasoline and diesel after the country set the “floor price†for refined oil prices on January 13. On a national average, the equivalent of No. 90 gasoline rose by 0.09 yuan per liter, No. 0 diesel rose by 0.1 yuan per liter, No. 92 gasoline rose by 0.09 yuan per liter, and No. 95 gasoline rose by 0.1 yuan per liter. The reporter took a look. After the price adjustment, the 50-litre fuel tank was filled with a box of oil, which cost about 5 dollars more. Up to now, this year's gasoline and diesel prices have gone through nine rounds of price adjustment cycles, including one down, two upswings, and six adjustments because international oil prices are lower than the “floor price†of US$40 per barrel. Since the beginning of this year, the price of gasoline has been increased by 145 yuan per ton, and the diesel price has been increased by 140 yuan per ton. Seeing such news, the car owners do not feel tired or love. Now driving is trying to find ways to save fuel. Many of today's car features claim that they can save fuel, but which one is more reliable? Today Xiao Bian came to chat with you, in the end these so-called fuel-efficient features in the end there is no use. Cruise control Also known as cruise control, speed control system. It is possible to maintain a fixed speed at the driver's requested speed without having to step on the accelerator pedal. Comments: The best economic speed means that the fuel consumption of the vehicle is the best when maintaining this speed. Different cars have different economical speeds because of their different weights. Therefore, in theory, if a car can maintain the best economic speed from beginning to end, this is the most fuel-efficient driving method of the car. However, this is only theoretical, if you can maintain or close to the best economic speed as possible, it is undoubtedly able to save fuel, and at this time the cruise control function is very helpful. In addition, because this function can reduce unnecessary speed changes, it can also save fuel to a certain extent. However, it does not mean that you must use the cruise control function to save fuel. If you set the speed to very low, or to a level as fast as 120 kilometers per hour, you can't save much oil. Turbocharged This is a technique for driving an air compressor driven by exhaust gas generated by the operation of an internal combustion engine. Simply put, the turbocharger can increase the horsepower output of the internal combustion engine by utilizing the heat and flow rate of the discharged exhaust gas. Comments: It is often the case that manufacturers use the "T" engine, which is a turbocharged engine, to flaunt their own models. However, after careful research, you will not find that this technology is actually only for increasing power, but it has nothing to do with fuel saving. In fact, this is the reason that the original intention of turbocharging is to increase the power level by utilizing the heat and flow generated by the exhaust gas under the condition that the engine displacement is constant. However, with higher and higher oil prices and more and more urgent requirements for environmental protection, people have found that models with similar horsepower have smaller displacements, which means that they are relatively more fuel-efficient. This point, the major car companies certainly will not let go, and is constantly being amplified to emphasize. Because of this, the illusion that turbocharger can save fuel will be available. However, the advantages of small turbocharged models and powerful power are worthy of recognition. Engine start-stop technology This technology refers to automatically stopping the engine when the vehicle is stationary, so as to achieve the purpose of saving fuel; and when the vehicle is ready to drive, the engine is automatically started immediately. However, "engine start-stop technology" is just a general technical name. Each car manufacturer has its own name, such as "Start-Stop Engine Start-Stop System". In fact, the meaning is the same. Comments: When the car stops, the engine stops immediately, which of course will have the effect of fuel saving. In the past, some masters and teachers will impart some old experience. For example, when the parking time is too long, the active flameout is to save fuel. The engine start-stop technology is designed to automatically shut down the engine each time the brake is depressed, and then automatically start the engine when it is started. This is equivalent to a fully automatic “fuel-ignition and fuel-saving†technology, which can effectively prevent the vehicle from stopping. Excessive fuel consumption occurs at idle, so it is possible to achieve a fuel-efficient effect. But what kind of fuel-efficient effect can you achieve? This is actually impossible to come up with real numbers. Because this is closely related to the driver's driving habits, road conditions, etc. If you are running on a freeway, there is no chance of shutting down the engine at all, except when you enter and exit the toll booth or when you temporarily park. If it is on a congested downtown road, it will be useful. Therefore, according to the proportion of road conditions that you normally take, you can probably know if this function on your car has played a role. This function has both advantages and disadvantages. Because the engine is continuously turned off and started, people's driving pleasure will be affected, and most of them will have different degrees of delay and vibration. Some owners simply turn off this feature because they are not used to it or they do not like it. Energy recovery system The energy recovery system includes a generator, a battery, and a smart battery management system that can monitor battery power. The principle of the energy recovery system is to recover the excess energy released by the vehicle during braking or coasting, or even driving, and convert it into electricity through a generator and store it in the battery for later acceleration. Comments: The so-called "flood and water does not flow outside the field" may be a true reflection of the energy recovery system. Whether it is the driver releasing the accelerator pedal or braking, it actually generates energy. The function of the system is to recover this energy as much as possible and store it in the battery for later use. This technology is commonly used in some models that use new energy technologies, such as pure electric vehicles, will be equipped with this feature. Because it is just a matter of excess energy recovery and stored in electrical energy, it does not produce any direct fuel savings. But from another point of view, if more energy is used to generate electricity or to drive, it will also save fuel as much as it can, and therefore it can also play a role in fuel-saving assistance. ECON mode The so-called economic, fuel-efficient model, its setting is specifically for fuel-efficient. Its role is that the vehicle achieves the effect of saving fuel and reducing emissions by intelligently adjusting the opening of the throttle and the conditions of electrical appliances such as air conditioners. Comments: Many owners, especially newcomers, will find that although the official fuel consumption of their own cars is there, or that people can drive very fuel-efficient, how can they not achieve that level and the actual fuel consumption is always higher. Why is that? This is related to the driver's technology and is also related to driving habits. Some owners like to slam on the throttle, but they don't have the essentials. The greatest role of the ECON mode is to reduce unnecessary throttle opening and closing, and even ECUs, engines, and transmissions will all be operated in accordance with low fuel consumption, such as faster shifts, intelligent adjustment of cooling conditions, and so on. Of course, after this mode is turned on, it will affect the output feeling of the power more or less. You will feel that power cannot always be promoted quickly. This is inevitable, or how to save fuel? However, many of these owners do not feel deeply because these functions are carried out unknowingly and are not obvious. Hybrid power system From the current level of technology, as long as the technology of two kinds of power sources is adopted, so-called hybrid power. Currently the most popular, it can be divided into weak hybrid MILD HYBRID (also known as mild hybrid, soft hybrid, micro-hybrid, etc.), moderate hybrid, heavy hybrid FULL HYBRID (also known as full hybrid, Strong hybrid, etc.), plug-in hybrid PLUG IN HYBRID. Of course, there are other such as fuel cells, solar cells, etc., but they are still not mainstream. Comments: Nowadays, many hybrid models are used, and the types used are also varied and have their own characteristics. Obviously, the higher the degree of hybrid power, the higher the fuel-efficient index, because the car is driven more by electricity. From the current point of view, if you want to save fuel, there is no doubt that hybrid power is the most fuel-efficient technology. If you ask pure electric? Excuse me, simply do not use oil technology, you do not have to compare it.
