1. Car maintenance "three filters" first
"Three filters" meansair filter,Oil filterAnd gasolineFilterIt is a checkpoint that air, oil and gasoline must pass. It provides clean oil and gas for the engine, thereby protecting the engine and improving the working efficiency of the engine.
1. Air filter
⑴ When cleaning the air filter, take out the filter element and use a soft brush to brush the dust on the surface of the filter element along the crease direction, and gently tap the end surface to remove the dust. At this time, pay attention to block the ends of the filter element with a clean cloth or rubber plug to prevent the dust from entering the inner surface of the filter element.
⑵ Be careful not to clean the filter element with water, diesel or gasoline, because the dust will block the pores of the filter element when wet, making it self-defeating, and increasing the air resistance, and the diesel is easy to be sucked into the cylinder, causing it to start running after installation.
⑶ If the filter element is found to be damaged, or the upper and lower ends of the filter element are warped and uneven, or the rubber sealing ring is aging, deformed or damaged, a new one should be replaced.
2. Oil filter
Generally, the engine oil should be changed every 7,500 kilometers, and the oil filter should be changed every 15,000 kilometers.
3. Gasoline filter
⑴Pay attention to the use of 93# standard engine oil, because unqualified gasoline will causeFuel SystemMalfunctions and premature damage to the engine.
⑵ When it is found that the fuel supply is insufficient, the engine power is reduced, and the vehicle is running weak, check whether the filter element is blocked.
⑶ It is generally required that the gasoline filter should be replaced every 15,000 kilometers.
2. Routine maintenance of the lubrication system
⑴More oil is not the better
The amount of oil in the oil pan should be controlled within the upper and lower scale lines of the oil dipstick, and should not be too much or too little.
If the engine oil is too much, the frictional resistance of various parts of the engine will increase, and the engine power will be lost. In addition, too much oil will jump into the combustion chamber, the engine burns oil, the oil consumption increases significantly, the carbon deposits inside the engine increase, and even pre-ignition, knocking, cylinder pulling, and serious damage to the engine are really lost. Soldiers.
On the contrary, if there is too little oil, some parts of the engine cannot be lubricated enough, causing abnormal wear of the parts.
⑵Inspection of engine oil
Regularly checking the oil level is an important task in daily maintenance.
⒈When checking the oil level,carYou must keep the horizontal position. After the engine stops, wait a few minutes for the oil to return to the oil pan.
⒉Take out the oil dipstick, wipe it dry with a clean cloth, and then reinsert the dipstick until it is stuck to the end.
⒊Then take out the oil dipstick again and observe whether the oil level is between max and Dmin.
If the oil level is below the mark below, you should add the same type of engine oil that meets Chery specifications according to the requirements in the user manual or the recommendations of the service station. About one liter of engine oil can make the oil level on the dipstick reach online.
⑶ Inspection of engine oil quality
While checking the oil level, you can also check the quality of the oil by observing words, colors, nose and hand, so that you can always know the lubrication status of the engine.
