很多车主在清洁爱车的时候，通常只会对漆面和内饰进行保养，却很少去打理发动机舱，一到水少的时节，发动机舱容易积聚尘土，如果长期不打理，里面的肮脏程度堪比“垃圾堆”。下面
济南奔驰汽车保养人员为您分析：
Many car owners usually only take care of the paint and interior when cleaning their cars, but rarely take care of the engine compartment. When there is little water, the engine compartment is prone to dust accumulation. If left untreated for a long time, the level of dirt inside can be comparable to a "garbage dump". The maintenance personnel of Jinan Mercedes Benz will analyze for you:
灰尘是如何进入发动机舱的？
How does dust enter the engine compartment?
所有的发动机舱都会进灰尘，而进灰尘量的多少也取决于这辆车的造价，越贵的车密封性自然越好，灰尘也就不会那么容易进去，而越是廉价的汽车，发动机舱的密封性越差，灰尘就更容易进入发动机舱，那么问题来了，究竟这些灰尘是怎样进入发动机舱的？
All engine compartments enter dust, and the amount of dust also depends on the cost of the car. The more expensive a car is, the better its sealing will naturally be, and dust will not easily enter. The cheaper a car is, the worse the sealing of the engine compartment, and the easier it is for dust to enter the engine compartment. So the question is, how does this dust get into the engine compartment?
其实灰尘进入发动机舱只有两种途径，一种是通过进气格栅进入，而进气格栅本身也有一定的滤尘能力，所以这种途径进入的灰尘量较少；另一种途径便是通过底盘进入灰尘，由于大部分车型出厂时并没有安装底盘护板，行驶时轮胎带起来的灰尘会透过底盘缝隙进入发动机舱，第八代凯美瑞“泥浆门”的导火索也是如此。
Actually, there are only two ways for dust to enter the engine compartment. One is through the intake grille, which also has a certain dust filtering ability, so the amount of dust entering this way is relatively small; Another way is to enter dust through the chassis. As most car models are not equipped with chassis guards when leaving the factory, the dust carried by the tires during driving can enter the engine compartment through the gaps in the chassis, and the fuse for the eighth generation Camry's "mud door" is also the same.
不清理发动机舱，后果有多严重？
How serious are the consequences of not cleaning the engine compartment?
灰尘的种类有很多，泥土、砂石和灰土等各种外来物质形成污垢后，一方面会导致机舱散热能力降低，直接降低发动机的能效，另一方面是加速零部件和线路的老化，金属零部件容易生锈，也增加了电线发生燃烧的风险。
There are many types of dust, and various foreign substances such as soil, sand, and ash can form dirt. On the one hand, it can reduce the heat dissipation capacity of the engine compartment, directly reducing the energy efficiency of the engine. On the other hand, it can accelerate the aging of components and circuits, making metal parts prone to rust and increasing the risk of wire burning.
而某些灰尘在高温环境下还会化身成为易燃物质，粘附在发动机零部件上，可谓是一枚移动的定时炸弹，加上灰尘覆盖在零部件表面，车主在做日常检查时很可能会忽略一些线路破损，管道漏油的情况，给爱车留下一个巨大的隐患。
However, some dust can also turn into flammable substances in high temperature environment and stick to engine parts, which can be described as a moving ticking time bomb scenario. In addition, the dust covers the surface of parts, so the car owner is likely to ignore some circuit damage and pipeline oil leakage during daily inspection, leaving a huge hidden danger to the car.
We have already explained the process and consequences of excessive dust entering the car engine again. We hope to provide you with good help. For more information, please come to our website http://www.lutongqixiu.com consulting service
