The new car ran 13000 km. What is the reason for feeling more and more expensive?

Hello, I'm Feng Zi, and I'm an auto mechanic. The new car ran 13000 km, and it felt more and more expensive. This problem has encountered many similar problems in our daily maintenance. To tell the truth, 13000 km is a new car for one year at most, and it will take less than one year to run diligently. What happened to the one-year-old car? Tell the maintenance master it's a waste of gasoline. When you meet a good master, I will patiently explain it to you. If you meet a bad master, I will give you a full set of cleaning, nozzle, spark plug and throttle. After washing, I will fool you and make you feel beautiful. In fact, the fuel consumption is still the original fuel consumption, but I spend money to comfort myself.

In the market environment of high oil prices, fuel consumption has always been a topic of concern to every car owner. Many car owners will talk about fuel consumption during the chat. In contrast, how can they find that their fuel consumption is higher than others? But one problem is that many car owners are comparing different brands of cars with different displacement. Can this be compared? We have encountered many such problems. We usually calculate the fuel consumption of a car several times. Fill up the fuel tank every time you turn on the fuel gauge light. Next time we turn on the oil meter light, we can calculate the fuel consumption and mileage, and then we can get the average fuel consumption of this tank of oil. After repeated calculations, we can roughly calculate the fuel consumption of your car.

Generally, the fuel consumption of vehicles within 60 thousand kilometers changes little because of the factors of the vehicles themselves, and a large part of them are caused by driving habits and road environment. So good driving habits not only affect driving safety, but also affect the ticket in your pocket. We don't need to be careful in the daily use of the car. A car is just a means of transportation. As long as it is maintained on time, there is no need to repair the conventional engine oil if it is basically within 654.38+10,000 kilometers. This car is not as expensive as we thought. My name is Feng Zi, and I am an auto mechanic.

If your car only runs 13000 kilometers, the mileage is not too much. Therefore, from the maintenance point of view, carbon deposits such as spark plugs, gasoline filters and cylinders can be temporarily ignored. This kilometer should be kept at least 1 time, right?

Another mechanical cause of this phenomenon is the electronic throttle. Now all vehicles use electronic throttle instead of the traditional cable throttle. At present, the air intake of the engine is judged simultaneously by the throttle opening and the intake pressure sensor. Because there is sludge and carbon deposit in the flip position of electronic throttle, it will lead to insufficient air intake (even idling in serious cases). When the computer detects that the throttle is inconsistent with the data of several sensors, it will increase the fuel injection and lead to an increase in fuel consumption.

The sludge at the throttle position mainly comes from the mixture of impurities not completely filtered in the air cleaner and oil vapor at the air inlet. There is no way to avoid this, only to clean the throttle every time according to the situation.

Because the throttle itself is a sensor, many cars need to initialize and return to the initial position after washing the throttle. If there is no carbon deposit, it will naturally save fuel.

There is also a part: if you often warm your car in the same place, turn on the air conditioner for a long time, and often use the big foot throttle, the fuel consumption will also increase.

If the same driver drives, the problem of driving habits can basically be ruled out. First, whether the road conditions of recent trips are congested or short-distance driving is mostly ruled out. It is normal that the fuel consumption will be relatively high if you mainly commute in the urban area.

Can you look at the average speed in the instrument? Generally speaking, the lower the average speed, the higher the fuel consumption. Try to find out the average fuel consumption, keep the economic fuel consumption at a constant speed, or run at a high speed, and see if it drops to a few fuel consumption, and you will know whether your car's fuel consumption is high or not. The main factors affecting fuel consumption are driving habits and road conditions, such as low-speed driving in pure urban sections and high fuel consumption, especially in urban congested sections.

1. Generally, it takes 30-60 seconds for the original floor heater of the cold car. If you add 1-2 minutes in extremely cold weather in winter, driving at low speed will save time and fuel.

2. When the outdoor environment temperature is low, the heating time of the hot car can be shortened by not turning on the heating after the cold car is started;

3. Avoid stepping on the accelerator again when starting, and each foot can reduce the instantaneous fuel consumption to outside the chart;

4. You can't slide in neutral when driving the automatic gear, and it costs more oil to slide in neutral with the EFI engine.

5. Maintain the clean air filter regularly, and check the tire pressure regularly. If the tire pressure is too low, the tire contact area will be large and the friction will be large, so the engine will have to increase its power and the fuel consumption will naturally increase.

Fuel consumption is affected by many factors, including driving habits and road conditions, including the oil used, whether the tire pressure is normal, whether there are faulty lights, and the change of manned load.
