Four Common Misunderstandings After Aviation Seat Modification

Aviation seat modification misunderstanding 1: More oil is indispensable

The oil in the crankcase cannot be added more or less. Excessive oil will increase the rotation resistance of the crank-connecting rod mechanism and increase the amount of oil splashed on the cylinder wall. Too much oil will increase carbon deposits in the combustion chamber, reduce engine power, and affect emissions. When the owner checks or refuels, he should refuel according to the scale on the oil gauge. The highest oil level cannot exceed the upper limit of the scale, and the lowest oil level cannot be lower than the lower line of the scale. It is usually appropriate to add the oil level to the middle of the two scales.

Aviation seat modification misunderstanding 2: Fetal high pressure should not be low

Some car owners like to inflate the tires with high air pressure. They think it can overload and save fuel. This is incorrect. High tire pressure will reduce the ground contact of the tire, aggravate tread wear, reduce the braking effect during braking, and affect driving safety. Too low tire pressure is not good. Too low tire pressure will not only affect driving safety and braking effect, but also accelerate shoulder wear and increase vehicle fuel consumption. When the owner uses an air pump to inflate the tire by himself, it should be inflated according to the air pressure specified by the manufacturer. The tire pressure label is usually located on the body or fuel tank cap.

Misunderstanding 3 of aviation seat modification: wheel screws should be tight rather than loose

According to the diameter, pitch and use of bolts in different parts of the car, the corresponding tightening torque is specified. Bolts that do not reach the specified torque are loose, and bolts that exceed the tightening torque are lengthened. Before tightening each component, it is necessary to master the tightening torque of each bolt, such as wheel bolts. The tightening torque of tire bolts for family cars is generally between 100-130N.m.

Misunderstanding 4 of aviation seat modification: seat belts should be tight rather than loose

Some owners believe that increasing the tightness of the belt can improve the cooling effect of the compressor and the power generation of the generator. Therefore, they made great efforts to increase the tightness of the belt, but they did not know that this practice was wrong. The connecting belt should be kept properly tightened, because tightening the belt will cause bearing overload, shorten the service life of components, cause belt breakage, and ultimately affect the normal use of the vehicle.
