What's wrong with the high fuel consumption of cars?

First, the relationship between driving habits and fuel consumption. Different people drive the same car, some people drive more fuel-efficient, and some people drive like "angry tigers", which is related to everyone's driving habits. Under normal circumstances, people who open the field like to step on the gas pedal and enjoy the unique feeling of being pushed. But in fact, this did not make the car run faster, but the fuel consumption doubled. Similarly, slamming on the brakes instead of collecting oil naturally will double the fuel consumption.

In addition, some people think that manual gear is difficult to open, which is mainly reflected in gear shifting. When some drivers speed up overtaking, they are often accompanied by the roar of the engine, which sounds more enjoyable, but in fact this is because the car itself does not have the acoustic effect brought by shifting gears, which will bring unnecessary fuel consumption increase. The speed must be consistent with the gear. Generally, 1 or gear 2 is used when the speed is below 20km/h, gear 3 is used when the speed is 20-50km/h, gear 4 is used when the speed is 50-70km/h, and gear 5 is used when the speed is 70-80km/h, which can maintain the fuel consumption normally.

Second, car failure and fuel consumption. Excluding the problem of man-made driving, the fuel consumption is still relatively high, which may be the problem of the car itself. D+ car guards believe that there are several main reasons:

1, spark plug. If the spark plug is broken, the ignition ability will be greatly reduced, and the mixture combustion will be insufficient and incomplete. Under normal circumstances, the life of ordinary spark plugs is only 30,000-50,000 kilometers, and iridium materials are about 50,000-80,000 kilometers. Therefore, when the fuel consumption increases sharply, car owners can check whether there is a problem with the spark plug.

2. Carbon deposition. With the increase of automobile service life, carbon deposits are easily formed in the engine, fuel injector, throttle and other parts, which leads to the decrease of combustion efficiency in the combustion chamber and the lack of automobile power. In this case, in order to maintain the normal running of the car, the fuel consumption will increase accordingly.

3. tires. The low tire pressure leads to the increase of friction between the car and the road surface, which makes the car have to increase the fuel supply and fuel consumption.

4. air conditioning. If the cooling and heating effect of the air conditioner is not good, in order to achieve the predetermined cooling and heating effect, the fuel consumption of the car will increase continuously.

Therefore, on the one hand, the increase in fuel consumption may be a problem of man-made driving habits, or it may be that the car has one or more of the above problems. Car owners should pay more attention in the daily driving process, develop good driving habits and do good maintenance, which can not only make the car more fuel efficient, but also prolong the service life of the car.
