福特福克斯噪音大什么原因

　　1、发动机噪声。除发动机体发出的机械声外，还包括进气系统噪声，即高速气体经空气滤清器、进气管、气门进入气缸，在流动过程中，会产生一种很强的气动噪声。发动机噪声主要由挡火墙和驾驶室的前底板部位传入驾驶舱。

　　2、轮胎噪声。轮胎噪声主要由三个部分组成：一是轮胎花纹间隙的空气流动和轮胎四周空气扰动构成的空气噪声；二是胎体和花纹部分振动引起的轮胎振动噪声；三是路面不平造成的路面噪声。

　　3、空气噪声。一是风噪，是由车身周围气流分离导致压力变化而产生的噪声。二是风漏，也叫吸出音，是由驾驶室及车身缝隙吸气而与车身周围气流相互作用而产生的噪声。三是其他噪声，包括空腔共鸣等。

　　4、车身结构噪声。车身结构噪声主要受两个方面因素影响，一是车身结构的振动传递方式，二是车身上的金属构件由于在里外作用下产生振动而发出的噪声。

　　2012新福1.6的是多点电喷，一个高转速型的发动机。

　　【英文介绍/For English】：

　　1. Engine noise. In addition to the mechanical sound emitted by the engine body, it also includes the noise of the intake system, that is, the high-speed gas enters the cylinder through the air filter, the intake pipe and the valve, and a strong aerodynamic noise will be generated during the flow. Engine noise is mainly introduced into the cockpit from the firewall and the front floor of the cab.

　　2. Tire noise. The tire noise is mainly composed of three parts: one is the air noise caused by the air flow in the tire pattern gap and the air disturbance around the tire; the second is the tire vibration noise caused by the vibration of the carcass and the pattern; the third is the road noise caused by the uneven road surface.

　　3. Air noise. One is wind noise, which is the noise generated by pressure changes caused by the separation of airflow around the body. The second is the air leakage, also known as the suction sound, which is the noise generated by the interaction between the cab and the body gap and the interaction with the air flow around the body. The third is other noises, including cavity resonance.

　　4. Body structure noise. The noise of the body structure is mainly affected by two factors, one is the vibration transmission method of the body structure, and the other is the noise emitted by the metal components on the body due to the vibration generated by the inside and outside.
