Misunderstanding 1: Always fill the tire pressure very high. Many drivers like to adjust the tire pressure to a high level. They feel that this can save fuel and overload. In fact, if the tire pressure is too high, the ground contact area of the tire will decrease, and the tread wear will be severe, which will reduce the brakes. Braking effect, no doubt this will affect the safety of driving; but the tire pressure is too low, the tire pressure is too low will accelerate the wear of the shoulder, it will increase the fuel consumption of the vehicle, it will also affect the safety of the vehicle and the vehicle. Braking effect.
Misunderstanding 2: Always add the engine oil is very full, many drivers are always worried that the engine oil is not enough, always give it full, but many people do not know that the excessive oil will increase the crank connecting rod The rotational resistance of the mechanism also increases the amount of oil splashed onto the cylinder wall. Excessive oil can also cause carbon deposits in the combustion chamber to increase, and engine power to drop, thereby affecting emissions. In fact, the amount of oil should not be too large, but it should not be too small. Under normal circumstances, it should be added according to the scale on the oil scale. The oil level should not exceed the upper limit of the scale. The minimum can not be lower than the lower limit of the scale. The level of the oil is on the upper side of the scale.
Misunderstanding 3: Fix the bolts of the vehicle too tight. Under normal circumstances, the bolts of various parts of the tanker truck have corresponding tightening torques according to their diameter, pitch and use. Will loosen, the bolt will be stretched beyond the tightened torque. We need to know the tightening torque of the bolt when tightening the bolt.
Misunderstanding 4: I always feel that the belt of the accessory is tighter than that of the belt. Many owners of the tanker think that increasing the tension of the accessory belt can improve the cooling effect of the compressor and the power generation of the generator. In fact, this is wrong. of. The accessory belt should maintain proper tension, because too tight a belt will overload the bearing, shorten the service life of the part, and cause the belt to break, which will eventually affect the normal use of the vehicle.
