Sales when buying a car often open the car hood，Many consumers see complex equipment in the hood，I will be confused and I can't see any doorway，Then you can only follow the sales of the sale，At this time, sales control the initiative of the concept of car，This is very unfavorable for consumers to buy a car for a car。So when we buy a car, we pass the car engine warehouse，What can we see，Not just the full advantages in the sales mouth，The seemingly good engine book data，Mastering a certain tips and us can see to a certain extent that a car is in the process、Material、and design aspect，Can it reach the level of a good car，This is undoubtedly helpful for us to choose a car and buy a car。

Many consumers now buy love cars，All will observe whether the engine compartment workmanship is neat，A fair workmanship can eliminate the wear between pipelines and the transition of high temperature zones to a certain extent，But the cockpit design that emphasizes neatly，However, the layout of the high temperature zone of different engines was ignored，will greatly reduce the design of the design and use。To cater to consumers，Some car manufacturers will use the engine cover，There are a variety of materials for these covers，Most of them are plastic material to add sound insulation cotton，To a certain extent, it can cover the messy engine compartment to play a certain heat insulation and sound insulation effect。But in some low -end models，Manufacturers will not increase costs to use high -quality engine cover，So it's just a decorative board，Without a substantial effect, it will affect the engine heat dissipation，High -quality engine cover will also be with the high temperature of the engine，Cultivation of melting odor。Especially during maintenance，Due to the vibration of the engine, the interface of the engine cover is deformed，Difficult to disassemble the engine seabet mymaintenance，It is difficult to install it when it is removed.。and because of the decoration of the engine cover，Some manufacturers are not so careful about the lines and layouts inside the engine.。

Consumers' layout of the engine warehouse，Should grasp a principle: It is best to open the engine cover for the low -end models when purchasing，Let's observe the internal engine，Whether there is a pipeline contact is too close，and whether the engine cover is only decorative。

The layout of the car engine compartment has a certain installation standard at the beginning of design，But some small manufacturers do not have too high requirements for artificial installation，As a result, the installation accuracy between different batches of different batches is very different。This has also caused many brake oil pipes or oil pipes and engine lids or other components in the engine cabin to be very serious。Conventional engine compartment internal pipeline design，It should be used to open the pipes, especially the oil pipes in the use of tie or covers，There is a certain wear distance，So if consumers observe the engine compartment, if the pipeline is overlapped or worn with parts，So pay attention。

Observe whether the liquid in the new car water tank has yellow impurities，It is also judging whether a car occurs in the transportation and storage process or a powerful standard for inventory cars。For during transportation，Vehicles that have occurred in the engine compartment，Due to damage to the internal pipeline of the car，Causes some rust，Cooling water flows back to the water tank，Causes the dirt and liquid yellow in the water tank (of course, the color of the antifreeze is yellow)。Followed by the inventory car because of the long -term launch，Extremely easy to form scale in the water tank，So observe the severity of the scale within it, you can determine whether it is an inventory car。

For the scale in the new car water tank, you can use a special cleaner，Then start the vehicle idle，Put the water in the water tank out of seabet appthe water tank for a while，Put a new antifreeze。

Open the engine compartment，It can also be found that the most significant vehicle process feature is the layout and process of the welding point of the vehicle，Now the welding of the vehicle body mostly use industrial robot welding，There are certain requirements in the accuracy and strength of welding，Not high welding accuracy and strength can cause the body to produce a large deformation under extreme conditions，and severe abnormal noise。

Conventional engine compartment welding may be welded，Especially new car，It is basically no rusty，If the welded joints in the engine cabin are covered with rust rusty，So you should doubt whether this car has been in water during transportation or preservation.，Even the original process of the original factory did not meet the manufacturing requirements。

Whether there are sound insulation cotton and sound insulation boards on the hood，It is also an important standard for measuring a car in workmanship and materials，The noise of more than 30 % of the car comes from the engine warehouse，So the sound insulation of the engine compartment is particularly important。Many manufacturers, especially low -end models, will reduce the sound insulation cotton of the engine compartment，Although through the optimization of sound source，Change the thickness of the hood can replace the sound insulation cotton to a certain extent，But the improvement of sound insulation cotton is understandable for the quality of the vehicle。In addition, the whole car modified sound insulation cotton is also a good choice，After all, the original sound insulation cotton still looks thin。

The insulation and sound insulation of the engine compartment and the cockpit，major car manufacturers have their own solutions，But most of the solutions used by most intermediate vehicles are thermal insulation tiles and thermal insulation pads，and most of them are aluminum materials。The thickness of the heat insulation tile and thermal seabet mypad has a great effect on the calorie of the engine compartment，If the consumer is driving for a long time，Feeling the changes in the foot of the feet is greater, then it means，Some manufacturers have been reduced in this part of the manufacturer，Among them, some sports cars with low shapes are particularly serious。

How to be the same as the old driver，Open the engine compartment elegantly and have its own unique insights on the layout and workmanship of the engine compartment when buying a car，can be a qualified old driver。
