When the car sales will often open the car hood, many consumers see the complex equipment in the hood, will be very confused and do not see what Road, it can only follow echoed sales, then sales for the car to master the concept of the initiative, which for consumers to buy cars talk price is very unfavorable. Then we through the car engine compartment, we can see that when buying a car what do, not just sales mouthful advantage of the mouth, seemingly good book engine data, and acquire a certain amount of tips we can to some extent seen on a car in the technology, materials and design, whether the car can reach a good level, which we have chosen for car buyers will undoubtedly have a huge help.
does not necessarily have a good car engine cover
Now many consumers buy the car, the engine will be observed whether neat cabin work and just work can put an end to a certain extent of wear and high temperature zone of transition between the lines, but only emphasizes neat cockpit design, while ignoring the high temperature zone layout of different engines, it will greatly reduce the design life . In order to cater to consumers, some car manufacturers will use the engine cover, which cover a wide variety of materials, mostly plastic add noise cotton, to a certain extent, can cover the engine compartment messy play a compartment thermal insulation. But in some low-end models, the manufacturers will not increase the cost of using high-quality engine cover, it is only a decorative plate, but no substantive action affects engine cooling, engine cover also poor quality with the high temperature of the engine, which produces melting odor. Especially in the maintenance of the engine because the engine vibration plate interface deform, causing the engine disassembly maintenance difficulties, it is difficult to be removed to install a secondary need to be replaced. And because of the engine cover decorated, some manufacturers for the internal layout of the engine exhaust line and it will not be so hard not conducive to the quality of the car.
Consumers select the layout of the engine compartment, we should grasp the principle: for the low-end model in the engine cover is preferably open in the purchase, to look inside the engine are there too close contact with the pipeline, and the engine cover whether merely decorative role.
Brake tubing or pipe from abrasion to grasp
layout engine compartment of the car early in the design of the installation there is a certain standard, but individual small firms for the accuracy of manual installation is not too high demands, so led to the mounting accuracy between the different vehicles of different batches is very different. It also caused a lot of wear of the engine compartment and the engine brake hoses or hose cover or other components is very serious. Conventional engine compartment pipeline design, should be used to tie or cover each conduit tubing especially arranged to open, there is a certain distance from wear, so consumers when viewed in the engine compartment if the line overlap each other, or and component wear, we should pay attention.
in the tank the liquid no yellowing no impurities
whether the liquid in the observation car tanks with a yellow impurity, is to determine a the car accident occurred or whether belonging to a powerful standard stock car during transport and during storage. For during transport, maintenance vehicle collision occurred in the engine compartment, because the conduit repair damaged car, resulting in some rust, the cooling water flows back into the tank, causing the tank scale and yellow liquid (of course, part of the antifreeze color is yellow). Second, because the long-term for the stock car does not start, the tank is extremely easy to form scale, so the observed severity scale within it can determine whether a stock car.
For scale may be used in the car tank special cleaning agents, and then start the vehicle is idling, the water in the tank after a time release, i.e., load a new antifreeze can.
in the engine compartment welding point of view manufacturers process
opening the engine compartment, may also be found in the most significant vehicle process is characterized by the vehicle welds layout and process, and now vehicle most of the body’s use of industrial welding robot welding, weld strength and accuracy in all have certain requirements, weld strength and accuracy is not high can cause the body to produce large deformation in extreme conditions, and abnormal sound serious.
Conventional welding point in the engine compartment, in particular car, is substantially free of rust, if the joints around the engine compartment covered with rust, then it should be doubt whether the car during transportation or savedProcess into the water, and even the original process did not meet manufacturing requirements.
whether there is noise on cotton
hood
whether a cotton noise insulation plate and
the hood, is an important criterion to measure the materials and workmanship of a car, the car has more than 30 percent of all the noise from the engine compartment, so it is particularly important for sound insulation of the engine compartment. Now many manufacturers, especially the low-end models will be less with cotton insulation of the engine compartment, although optimized for a sound source by changing the thickness of the hood cotton insulation may be substituted to some extent, but the quality of cotton noise for enhancing the sense of the vehicle is understandable. Also late whole car modified cotton insulation is a good choice, after all, cotton insulation factory still look thin.
the front of the cockpit tiles
of the noise insulation of the engine compartment and cockpit, the major car manufacturers have their own program, but most of the middle of the vehicle used in the program are tiles and insulation pads, and most of them are made of aluminum material. Tiles and the thickness of the insulating mat for heat insulation of the engine compartment has a great role, if consumers in the long driving process, the foot feels it shows large temperature changes, carried out a number of manufacturers in this section Save with which to compare some of the low sports car styling is particularly serious.
and how old drivers as gracefully open the engine compartment and the configuration and layout work for the engine compartment when the car has its own unique insights, in order to become a qualified old driver.
