【Owner's home car knowledge】With the passage of time and the progress of the times, cars have quietly entered the homes of ordinary people. A car is no longer just a means of transportation, it is more like our friend, and even integrated into our family, becoming an important member of the family. We take great care of our car, even reaching the level of "love", of course we cannot ignore the details of our car. Even if you really "love" it, you can't love it too much. For example, in order to better protect the engine, you overfill the engine oil, these are all wrong! Let me introduce how to better "love" the car instead of "harming" the car.
Misunderstanding 1: More oil is better than less
Do not add more or less oil in the crankcase. Excessive oil will increase the rotational resistance of the crank connecting rod mechanism and increase the amount of oil splashed on the cylinder wall. Excessive engine oil will lead to increased carbon deposits in the combustion chamber and reduced engine power, which will affect emissions. When the car owner checks or adds oil, he should add it according to the scale on the oil scale. The highest oil level should not exceed the upper limit of the scale scale, and the lowest level should not be lower than the lower line of the scale scale. The oil level is usua

The highest oil level should not exceed the upper limit of the scale scale, and the lowest level should not be lower than the lower line of the scale scale. The oil level is usually added to the upper middle of the two scales. More appropriate.
Myth 2: Tire pressure should be high rather than low
Some car owners like to inflate the tire pressure very high, thinking that it can overload and save fuel, which is wrong. If the tire pressure is too high, the ground contact surface of the tire will be reduced, the tread wear will increase, and the braking effect will be reduced, which will affect driving safety. Too low tire pressure is not good either. In addition to affecting driving safety and braking effect, too low air pressure will accelerate the wear of the tire shoulder and increase the fuel consumption of the vehicle. When the car owner uses the air pump to inflate himself, he should inflate according to the air pressure specified by the manufacturer. The tire pressure label is usually located on the body or the fuel tank cap.
Misunderstanding 3: The wheel screws are tighter than loose
The bolts of various parts of the car have corresponding regulations on the tightening torque according to different diameters, pitches and uses. If the specified torque is not reached, the bolts will loosen, and the bolts will be stretched if the tightening torque exceeds the specified torque. Before tightening each component, it is necessary to know the tightening torque of each bolt, such as wheel bolts. Usually, the tightening torque of household car tire bolts is between 100-130N·m.
Misunderstanding 4: The accessory belt should be tight rather than loose
Some car owners think that increasing the tension of the accessory belt can improve the cooling effect of the compressor and the power generation of the generator, so they keep increasing the tension of the belt, but they do not know that this approach is wrong. The accessory belt should maintain a proper tension, because if the belt is too tight, the bearing load will be too large, which will shorten the service life of the components and cause the belt to break, which will eventually affect the normal use of the vehicle.
