In fact, there are many easily overlooked details of car maintenance caused by increased fuel consumption. Car age and fuel consumption is not necessarily linked. As long as we usually do some maintenance and replacement parts, fuel consumption will decline. Today Xiaobian To talk to you, which parts change, you can let the fuel consumption down.
1, pay attention to oil, clean up carbon deposition
Poor quality of gasoline will make the engine more carbon deposition, and excessive coke will make the intake pipe wall roughness, affect the intake effect and the quality of the mixture.For example, usually 1 liter of oil can produce kinetic energy at this time to 1.5 liters Oil can be achieved, which allows a sharp rise in fuel consumption, so the quality of gasoline can not be ignored, while if the vehicle's engine that there is carbon deposition suspect, timely clean-up.
2, regular replacement of spark plugs
Do not underestimate a small spark plug, its role is to use high-voltage electric spark ignition mixture.If the damage will make the ignition energy, mixed gas combustion is not uniform, resulting in slower car speed, fuel consumption rise.
Ordinary spark plug life of only 3-5 million kilometers, iridium spark plug life of about 5-8 million km, platinum spark plugs can reach 100,000 km of life.
3, see the tire pressure and tire wear
Tire pressure is too low, will increase the friction between the tire and the ground, the resistance becomes larger, the fuel consumption will rise.We in the daily driving found that the car's taxi distance is significantly reduced, it should check the tire pressure is in line with the pressure standard.
Our normal tire pressure is how much? Open the vehicle's fuel tank cover, the above are marked. (Varies from vehicle to) the normal normal tire pressure in about 2.5bar, the summer may be appropriate to reduce. Now more and more models have Tire pressure monitoring configuration, easy to grasp the situation in real time.
Also remember to check the degree of tire wear, if the tire wear serious, it will often slip phenomenon, the same fuel consumption will increase.
4, timely replacement of oxygen sensor
What is an oxygen sensor? In a nutshell, this is a ceramic component located on the exhaust pipe of the engine to detect and control the oxygen to fuel ratio. After a long period of use, the electronic fuel injection system computer can not exhaust The oxygen concentration in the tube, the gas mixture in the engine tend to be high, fuel consumption will increase.
The above methods have tried, but the fuel consumption is still not back to the previous fuel consumption, you can go to check the status of the oxygen sensor, the oxygen sensor usually need to check in the 8-11 million km replacement, it is indeed one easily overlooked by everyone Car parts.
