Cars are becoming more and more popular and new drivers are constantly joining. However, many drivers do not understand the car, but there are many errors in driving. We will ask experts to solve the misunderstandings one by one.
The tighter the bolt, the better. There are many fasteners on the car that are connected by bolts and nuts. It should be ensured that it has enough pre-tightening force, but it cannot be tightened too tightly. If the tightening is too tight, on the one hand, the connection member will be permanently deformed under the action of external force; on the other hand, the bolt will be permanently deformed by tension, the pre-tightening force will be reduced, and even a sliding buckle or breaking phenomenon will occur.
The tighter the drive belt, the better the water pump and generator of the automobile engine are driven by the V-belt. If the belt is tightened too tightly and easily deformed, the pulleys and bearings are liable to cause bending and damage. The belt tension should generally be adjusted so that when the belt is pressed in the middle, the amount of sinking is preferably 3% to 5% of the center distance of the pulleys at both ends.
The more the oil, the better. If there is too much oil, the crankshaft shank and connecting rod will stir violently when the engine is working, which will not only increase the internal power loss of the engine, but also increase the oil that splashes on the cylinder wall, resulting in the burning of the oil malfunction.
Therefore, the amount of oil should be controlled between the upper and lower mark lines of the oil dipstick.
Occasionally using a low-grade oil does not have to use a low-grade oil once, which may cause permanent damage to the engine. Low-grade oil has poor wearability, is easily oxidized and acidified, and has strong corrosion. It can easily leave carbon deposits and sludge in the engine and clog filters and oil passages.
