The fuel consumption of HNA Mazda 323 is on the high side, reaching 1.5 yuan per kilometer. What happened?

If you pay more attention to your driving and car habits, it is not a problem to reduce fuel consumption to the most reasonable range. The following are the reasons why 10 may increase fuel consumption. I believe this will help you. First, the warm-up time in the morning is too long or the driving distance is too short. I believe many car owners have a good habit of warming up their cars in the morning, but just waiting for the speed to drop to normal or the water temperature to rise to normal is tantamount to finding trouble for their wallets. Experts suggest that car owners in most parts of China can shift gears about half a minute after the vehicle starts, and drive at 1 for a certain distance before driving normally. For some northern cities, when it is too cold in winter, the hot train time can be appropriately extended. In addition, when the engine water temperature is too low, the computer will control the fuel injector to inject more fuel, so if your commute distance is close, the winter weather is cold, and the water temperature is not easy to rise to normal, then your car may become a typical example of high fuel consumption. 2. Abnormal tire pressure or replacement of large tires. Experts say that when tires are under-inflated, it will affect fuel consumption. When the tire pressure is too small, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally waste more oil. Similarly, if the same displacement, the same model, the same load and other cars. Assuming that car A uses original tires and car B uses wider tires, car B will consume more fuel than car A because of the increase of vehicle driving resistance. Of course, if the owner inflates the tires in Dachuan and replaces them with narrow tires, it will increase the possibility of puncture and eccentric tire wear and reduce driving comfort. Thirdly, if you don't plan the route, drive on crowded roads and change lanes frequently, traffic jams will occur in many big cities, and some experienced drivers will choose the least crowded route between the starting point and the destination. In this regard, it is recommended that car owners plan their driving routes in advance, pay attention to local traffic information and road conditions, and avoid congested road sections. Because you reduce the start and stop of vehicles and drive at an economical speed, this is equivalent to saving fuel for you. Also, many car owners often change lanes on the road. At this time, you not only have to accelerate and decelerate, but also the driving distance is not as short as the straight-line distance, so this is one of the reasons for the increase in fuel consumption. Fourth, friends who "clean" their cars from time to time suggest that the appearance of vehicles should be cleaned frequently, and waxing regularly is also a good way to save fuel. The biggest resistance when the vehicle is driving comes from the air. If your vehicle has had an accident and its body is deformed, it may affect the aerodynamics of the vehicle. Even a slight bump or depression will affect fuel consumption, and too much mud on the car body and snow on the car body in winter are also the burden of the vehicle. Fifthly, when idling for a long time without turning off the fire or frequently striking the fire, it is suggested that the owner can choose to turn off the fire when waiting for a long time without moving the vehicle. We can often see that taxi drivers choose to turn off the engine cart when waiting in line. In fact, this is the best way to save fuel when encountering the same situation. You might as well turn off the engine when you are waiting for a friend and there is a traffic jam. Whenever the engine is started, there will be more computer-controlled fuel injection, so starting the engine frequently for a period of time will definitely increase the fuel consumption of the vehicle. Auto repair experts also said that starting the engine frequently is a sign of "car abuse". Sixth, when driving, it is recommended to refuel hard and brake frequently. It is very undesirable to slam on the accelerator with your big foot before starting in the movie. After all, the stop line is not the starting line of the track. Starting, refueling and shifting gears at a normal speed can save a lot of oil over time. If it is not necessary to drive on the road, it is best not to overtake frequently. Driving at a constant speed can reduce fuel consumption. In addition, mastering the following distance between you and the car in front and minimizing unnecessary braking actions can also bring you fuel-saving happiness. Seventh, the vehicle increases the load without reason. Many friends who just bought a car like to put all kinds of decorations and exterior decorations on the car, and even worse, they simply move their offices and homes into the car. Blindly installing large enclosures, tails, winches and luggage racks on the vehicle will also increase the fuel consumption of the vehicle. The fuel consumption of vehicles will increase with each additional weight, so it is suggested that car owners decorate their cars within a reasonable range. Friends who have entered the misunderstanding of over-decoration should "reduce the burden" on their cars as soon as possible. Eighth, the viscosity of engine oil is the main index of engine oil. For example, 15W-40, where "w" stands for winter, and the smaller the number in front of it, the thinner the viscosity of the engine oil, the better the fluidity, the lower the available ambient temperature and the better the engine protection ability during cold start; The number after "W" is the index of high temperature resistance of oil. The larger the number, the better the protective performance of oil at high temperature. Too much choice of engine oil with high viscosity will increase the resistance of engine parts, which will not only consume power, but also increase fuel consumption. The ninth kind of low-speed or high-speed low-speed driving may happen to new drivers. In many cases, the vehicle speed is already very high and you don't have a corresponding upshift, so the fuel consumption naturally soars with the increase of engine speed. You may want to select the appropriate shift timing by referring to the reasonable speed and gear of the vehicle. The other is that the speed is too low, but the gear is still high. The most obvious feature of this situation is that the engine and body have started to shake and may turn off at any time. At this time, some friends will choose to increase the throttle, and increasing the throttle means increasing the fuel injection. The best solution to this situation is to downshift. In the tenth summer, the windows are all air-conditioned when there is traffic jam. In summer, people in air-conditioned cars will naturally be much more comfortable to drive, but with the increase of engine load, fuel consumption will also increase. At this time, some car owners choose not to turn on the air conditioner and open all the windows to cool down, but the driving resistance increased by opening the windows when the vehicle is driving will even be greater than the power consumption of the air conditioner compressor, so it is appropriate to open the windows to cool down at low speed, and it is more cost-effective to turn on the air conditioner at medium and high speed. Also, the fuel consumption of vehicles with traffic jams will increase. If the air conditioner is turned on ... So if the temperature is acceptable in traffic jams, car owners who want to save fuel may wish to turn off the air conditioner!
