Misunderstanding 1: The engine oil is more than necessary
The oil in the crankcase cannot be added or added. Excessive oil can increase the rotation resistance of the crank linkage and increase the oil splashed on the cylinder wall. Excessive oil can cause increased carbon deposits in the combustion chamber and reduce engine power, which can affect emissions. When the owner checks or adds oil, it should be added according to the scale above the oil scale. The maximum oil level cannot exceed the upper limit of the scale. The minimum must not fall below the scale scale. The oil level is usually added to the center of the two scales. More appropriate.
Misunderstanding 2: tire pressure can not be high
Some owners like to charge the tires with high air pressure. They think that it is both overloaded and fuel-efficient. This is not true. Excessively high tire pressure will reduce the tread area of ​​the tire and increase the wear of the tread, reducing the braking effect when braking, which will affect the safety of driving. Tyre pressure is also not good, and low air pressure will not only affect the safety and braking effect, but also accelerate the wear of the shoulder and increase the vehicle's fuel consumption. When the owner uses the air pump to inflate, it should be inflated according to the manufacturer's prescribed air pressure. The tire pressure label is usually located on the body or the fuel tank cover.
Myth 3: Wheel screws are tight
The bolts of various parts of the car, according to the diameter, pitch and the use of the different, its tightening torque has a corresponding provision, can not reach the specified torque bolt will loosen, beyond the tightening torque bolt will be elongated. Before tightening the components, it is necessary to first grasp the tightening torque of each bolt, such as the wheel bolts. Generally, the fastening torque of the tire bolts of household cars is between 100-130 N·m.
Myth 4: Attachment belts will not loose
Some owners think that increasing the tightness of the accessory belt can improve the cooling effect of the compressor and the amount of power generated by the generator. Therefore, it will be hard to increase the tightness of the belt. They are unaware that this is wrong. The accessory belt should maintain a proper degree of tension, because over-tightening of the belt can cause excessive bearing load, shortening the service life of the component, and causing the belt to break, which will eventually affect the normal use of the vehicle.
