Solutions for high fuel consumption of Excelle 13 models

The methods to solve the high fuel consumption of Excelle are: cleaning the carbon deposit in the engine, checking the state of oxygen sensor, replacing the three filters regularly, and checking whether the electronic control unit is normal. Clean up the engine carbon deposit: Too much carbon deposit in the engine is a very important reason, mainly due to the use of inappropriate oil products. It is recommended to add a certain amount of detergent when refueling. If the effect is not obvious, it means that the engine has a lot of carbon deposits. In this case, the car must drive to the 4S shop, and the professional technicians will clean up the carbon deposits in the engine. Moreover, it is best to drive at high speed after cleaning, which is helpful to increase the exhaust volume and let the stronger airflow bring out larger carbon particles.

Check the oxygen sensor:

As the internal control unit of automobile, oxygen sensor mainly monitors the air-fuel ratio of engine. Once damaged, the air-fuel ratio of the engine will be unbalanced, and the fuel consumption will definitely increase suddenly. The oxygen sensor is damaged, and the exhaust pipe will emit dark exhaust gas when the vehicle is driving, so the oxygen sensor should be replaced. Replace the three filters regularly: the oil filter, air filter and gasoline filter must be replaced regularly during the use of the vehicle. If it is not replaced for a long time, it will become dirty and greasy, which will affect the use and send an error message to the engine control unit, resulting in insufficient fuel combustion and increased carbon deposition in the engine. Check the electronic control unit: although the electronic control unit of the engine is highly reliable, some faults will inevitably occur in those cars with long service life. For example, a manifold block is damaged, the bolt is loose, the solder joint of an electronic component is open, and the resistor-capacitor component fails. Problems with the engine control unit will directly lead to difficulties in starting the vehicle, increased fuel consumption, poor power performance, black and thick exhaust and so on.

How to reduce the fuel consumption of cars;

1. In the era of high oil prices, fuel consumption has become the most concerned topic for many car owners. When the fuel consumption of a car is high, the owner should not blindly judge that the fuel consumption of the car is increasing and do a lot of unnecessary maintenance. If you feel that the fuel consumption of a car is increasing, first think about whether your recent driving habits and driving roads are different. If you are not sure, you can also go to the maintenance station.

2. Correctly grasp the long time or driving distance of the hot car in the morning. I believe that many car owners have a good habit of warming up their cars in the morning, but blindly waiting for the speed to drop to normal or the water temperature to rise to normal is tantamount to a problem with their wallets. Experts suggest that car owners in most parts of China can shift gears about half a minute after the vehicle starts, 1 and then drive normally after a certain distance. For some northern cities, when it is too cold in winter, the heating 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 short and the water temperature is not easy to rise to normal in cold winter, then your car may become a typical example of high fuel consumption.

3. Keep the tire pressure normal or replace large tires, because too low tire pressure will affect fuel consumption. If the tire pressure is too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally become more waste oil.

5. Wash the car regularly. Conditional friends suggest cleaning the appearance of cars frequently and waxing regularly is also a good way to save fuel. The biggest resistance in the process of vehicle driving comes from air. If your vehicle is deformed in an accident, it may affect the aerodynamic performance of the vehicle. Even a slight bump or depression will affect fuel consumption. In winter, too much mud and snow on the car body is the same burden for the vehicle.

6. Don't turn off the engine or ignite frequently when idling for a long time: When the vehicle is not moved for a long time, it is suggested that the owner can choose to turn off the engine. In addition, auto repair experts also said that starting the engine frequently is a kind of "car abuse". @20 19
