The wrong way of semi - trailer maintenance. Semi-trailer is a kind of large vehicle used for long-distance transportation, its use has been more and more widely, the use of semi-trailer is inseparable from the maintenance, but there are many people in the process of using the maintenance method is not right, the following is about the wrong method of semi-trailer maintenance.
1. Remove the engine thermostat blindly
Some drivers think that the driving engine temperature is high or not low, so blindly remove the engine thermostat, coolant can only be a large cycle, can not adjust the cooling strength, so the engine often works in low temperature conditions, resulting in the loss of power, wear, fuel consumption increase, and so on. In fact, low temperatures are bad for engines. Vehicle specifications should be limited at normal temperatures to ensure engine life.
2. The tighter the fan belt, the better
Tight is not better. Belt too tight will not only make it stretch or damage, shorten the service life of the belt, but also because of too much pressure, resulting in bending deformation of the generator shaft, pump shaft and bearing early damage. Loose semi-trailer engine fan belt should meet technical requirements, generally normal belt assembly deviation of 10 to 15 mm is appropriate.
3. Engine idling
Many drivers know that the car is just starting and if the engine speed is too high it will damage the engine due to poor lubrication. However, few people know that if used idle for a long period of time to heat up, due to low speed, the oil pump cannot quickly press down the lubricating oil for all lubricated surfaces, and all moving parts of the engine will work under dry friction or semi-dry friction conditions. At the same time, due to poor atomization of low-temperature fuel, the unburned fuel enters the crankcase, washes off the oil film of the cylinder wall, and accelerates the wear of parts. Therefore, in low temperature conditions, after the engine starts a few seconds, should improve the idle speed fast heating, improve the engine lubrication conditions.
4, tire pressure, and high not low
Some drivers like to call tire pressure high, thinking it can overload and save energy. This is not true. Tire pressure is too high, will reduce the tire ground, wear, but also easy to breakdown. At the same time, because the tire pressure is too high, it can reduce the tire adhesion coefficient, reduce the brake braking effect, increase CeHua, and cause greater harm to driving safety. Similarly, low tire pressure is not good, will cause the tire shoulder, put the tire, fuel consumption increase, and so on. So, the right thing to do is to press the pneumatic tyre indication at standard pressure, and you are generally more appropriate at standard plus or minus 5%.
