Old driver who still remember the year you learn in driving school car, the two lines will normally be in the front coach cabin cover car put reference materials, we go straight, turn, parallel parking, storage is going to be loud in the side shouting "identify the point ... the point" At this time we will align the reference line of sight was like target practice and pavement markings pointing to three-point line to determine body position. Two lines seemingly simple cabin design is actually a great value exists, almost every car has, then I listen to you explain its use.
Two lines acting on the car hood: two lines actually stiffener panel, to enhance the strength of the steel sheet, is pressed against the relatively large area of ??the iron plate without these two ribs, the pressing will cause stress concentration at stress points subsidence, but if pressed with the ribs would not be so easily deformed, so it simply is used to increase the degree of resistance to deformation.
The hood is made of rubber and foam materials made of aluminum, while reducing engine noise, on the other hand due to the heat generated when the isolated operation of the engine cover effectively protect paint surface, prevent aging.
Also play a secondary line of sight of the driver, the vehicle is running, the front reflected natural light and realize the driver determines the road ahead is critical, the reflected light can be effectively adjusted by the shape of the hood to reduce the effects of light on the driver .
It is also undeniable aesthetics, tough lines give the car to create a more three-dimensional sense of muscle.
