The wrong way to use the vehicle training equipment and the correct repair
Nov 12, 2021
People in the use and maintenance of cars in the long term to use the concept has become the wrong. These misconceptions sometimes seem to be correct, but in fact they are not. They are very harmful and may cause the loss of the vehicle and the threat to the safety of the person.
1, blindly remove the engine thermostat
If the thermostat is removed blindly due to the high temperature of the engine, the coolant can only be used for large circulation, and the cooling intensity cannot be adjusted, which makes it difficult to ensure the engine to work at a more appropriate temperature. Instead, the engine often works at a low temperature, causing the engine power to drop, wear to speed up, and fuel consumption to increase. If the engine temperature is still high after maintenance or replacement of the engine thermostat, other parts of the cooling system should be inspected and maintained, and the thermostat should not be removed. The right operation method: if blind demolition due to high engine temperature thermostat, cooling fluid can only to large cycle, can't adjust cooling intensity, it is difficult to guarantee the engine work under the appropriate temperature, on the contrary make engine often work in low temperature condition, cause the loss of engine power, wear and tear, fuel consumption increase. If the engine temperature is still high after maintenance or replacement of the engine thermostat, other parts of the cooling system should be inspected and maintained, and the thermostat should not be removed.
2, the engine temperature fear high fear low
Some people think that the engine temperature is not afraid of high or low when driving. In fact, the engine temperature is very dangerous. The service life of the engine should be guaranteed by running at the normal temperature specified in the operation manual.
3, pump fan belt as tight as possible
The tighter the belt, the better. Belt too tight will not only make it elongate or break, shorten the service life of the belt, but also because the tension is too large, resulting in the generator shaft, water pump shaft deformation bending and bearing early damage. The tightness of automobile engine fan belt should meet the technical requirements, and the deflection of normal belt assembly should be 10-15mm.
4, the engine with idle speed heating
With idle speed heating up, due to the low speed, the oil pump can not quickly put lubricating oil into the lubrication surface, oil pressure is also low, so that the engine moving parts in dry friction or semi-dry friction state of work; Due to the poor atomization of fuel at low temperature, the unburned fuel will escape into the crankcase and wash away the oil film on the cylinder wall, which will also accelerate the wear of the parts. Therefore, a few seconds after the engine started, the application of fast idle temperature rise, improve the engine lubrication conditions.
5. Bake oil base with torch
In winter with the torch baking oil bottom, not only will make the additives in the oil chemical changes, lost the original performance, but also will make the oil cement, oil bottom deformation, easy to cause fire. The best practice is to choose the appropriate oil according to the local winter minimum temperature. Where possible, it is best to park your vehicle in a garage with insulation.
The more advanced cleaning methods are ultrasonic cleaning and nuclear cleaning, but the most commonly used and simplest methods are physical cleaning and chemical cleaning. You can use both methods.
