It is well known that the longer the car is used, the higher the fuel consumption. Many drivers will attribute the increase in fuel consumption to the aging of the car, in fact, the increase in fuel consumption of the car has a lot to do with the driving habits and the aging of parts, especially the following parts are the culprits that lead to the increase in fuel consumption.
First, the battery
Why is the increase in fuel consumption of automobiles related to batteries? This is because the circuit, as an important part of the car, has a very close relationship with the oil circuit. As a consumable with a service life of only 2-3 years, the battery will be used for too long to produce power loss, resulting in insufficient starting voltage. The battery starting voltage is insufficient, the motor can not drive the engine, the spark plug can not jump out of the strong and powerful spark, the ignition energy will become lower and lower, and the fuel consumption of the car will become higher and higher. Therefore, do not think that the battery is not broken to continue to use, in order to reduce the fuel consumption of the car, you must replace the battery in time.
Second, spark plugs
If the engine is the heart of the car, then the spark plug is the heart of the engine. Without spark plug ignition, the engine would not work. The life of the general OX spark plug is 20,000 kilometers, the life of the platinum spark plug is 50,000 kilometers, and the longest life of the iridium spark plug can reach 60,000 to 80,000 kilometers. When the spark plug is damaged or the ignition efficiency is reduced, the air in the cylinder cannot be fully burned, and the fuel consumption of the car will also increase. Therefore, when the fuel consumption of the car suddenly increases, be sure to check whether the spark plug is malfunctioning or aging.
Third, tires
Tires, as the only parts on the car that are in direct contact with the ground, are one of the important factors that determine the level of fuel consumption. When the tire pressure of the car tire is too low, it will cause the contact area of the tire with the ground to increase, and the resistance will also increase, so the fuel consumption of the car will become higher and higher. In addition, when the car tire wears seriously, it will cause the tire to slip, resulting in power loss, so that the fuel consumption of the car will also increase. Therefore, we must regularly check the tire pressure and tire wear degree to avoid affecting the fuel consumption of the car.
Fourth, the engine
In fact, it is not the engine that affects the fuel consumption of the car, but the carbon deposit of the engine will cause the fuel consumption of the car to increase. Car use for a long time will inevitably produce carbon deposits, long-term addition of poor quality fuel and long-term overheating of the car will lead to carbon deposition. Carbon deposits will thicken the intake pipe wall, affecting the quality of the intake and mixing gas, and the fuel consumption of the car will also increase. Therefore, it is necessary to clean up the carbon deposit regularly, and the owners can clean up the carbon deposit every 20,000 to 40,000 kilometers to prevent the fuel consumption of the car from rising.
Fifth, oxygen sensor
When it comes to oxygen sensors, most car owners are probably unfamiliar. The oxygen sensor is a ceramic element located on the exhaust pipe of the engine, whose role is to check the concentration of oxygen in the exhaust. When the oxygen sensor is used for a long time, various failures may occur, resulting in inaccurate oxygen-fuel ratio values, the gas mixture in the engine will become more concentrated, and the fuel consumption of the car will increase. Therefore, it is best to replace the oxygen sensor every 8-110,000 kilometers.
