What is the reason why ix35 consumes more and more fuel?

Why is the fuel consumption of ix35 getting higher and higher?

The causes and solutions of high fuel consumption of ix35 are as follows:

1. Due to the influence of temperature, the increase of fuel consumption is normal. Generally, when the temperature is low in winter, the fuel consumption will increase, which is similar to that in summer. This is because the heat emitted by the engine has increased. Secondly, it takes a long time to warm up the car in winter, and it takes some time and more gasoline from starting to normal water temperature.

The vehicle has not been maintained for a long time. Dirty oil and air filtration will also lead to an increase in fuel consumption. Dirty oil will lead to poor lubrication, which will lead to an increase in the resistance of all moving parts of the engine. More energy is needed to overcome the resistance, which will lead to an increase in fuel consumption. Vehicles requiring regular maintenance;

3. Spark plugs. Spark plugs are easily overlooked. Some vehicles have not been replaced after driving more than 6,543,800 kilometers, and the service life of spark plugs has also reached. Although it can still be used, due to insufficient ignition energy, it will delay ignition and miss the best ignition time. For example, when the piston is near the top dead center, gasoline should have been ignited. Due to insufficient ignition energy and delayed ignition, the piston began to move down before ignition. This will lead to a part of power loss, a lot of energy is not used to do work, and it will also lead to incomplete combustion, further increasing fuel consumption, and the spark plug needs to be replaced.

4. Insufficient air pressure. Insufficient air pressure will increase the contact area between the tire and the ground and increase friction, that is, the driving resistance will increase and the fuel consumption will increase. Insufficient air pressure will also shorten the life of tires, and high-speed driving will also increase the chance of puncture. Tire pressure should be checked regularly, at most once every two months. If there is tire pressure monitoring, you can check it directly. If there is no tire pressure monitoring, each tire should be measured manually with a tire pressure gauge.

5. Some sensors have incorrect data, such as water temperature sensor and oxygen sensor. The sensor is not completely damaged, but the data is inaccurate, and the fault light will not light up, so it is difficult to find out whether the data stream is detected by the computer. For example, if the temperature from the water temperature sensor is low and the oxygen content displayed by the oxygen sensor is too high, the computer will control more fuel injection, which will eventually lead to incomplete combustion and increase fuel consumption. It is necessary to check the sensor data regularly.

6. There is too much carbon in the car. The places where carbon is deposited are throttle, fuel injector, air inlet and piston crown. Excessive carbon deposition anywhere will lead to incomplete combustion, which will lead to increased fuel consumption. It is necessary to clean up the carbon deposits on vehicles.
