The old driver has the following sentence: The bad car first rots, so many drivers will choose to install the engine undercarriage to protect the bare chassis. However, some people think that the lower guard plate has limited effect and may also affect the engine sinking in the event of an accident. . Adding the engine guard will not affect the safety? What material under the guard plate cost-effective? This issue will see the car school to talk about the engine under the guard board.
Dirt, rainwater, and sand fly will cause varying degrees of erosion of the exposed chassis, and uneven road surfaces may also damage the oil pan.
At this time, it is very necessary to install an engine guard plate. It can effectively prevent the sediment from being caught in the chassis and protect the oil pan from being damaged by stones or raised pavement.
Of course, if you have a big stone and you want to open it, you will only be on the shield of the US team.
In addition, the lower guard can also optimize the aerodynamic performance of the car, especially when running at high speed to reduce wind noise and fuel consumption.
Most high-end models come with their own guards. Some family cars do not have mounting holes.
'I heard that under the shield will affect the engine sink.'
The engine sinking technology. If the front of the car hits, the front engine may be pushed into the cab, causing personal injury. With the sinking design, the engine can move downwards in front of the collision, without directly pressing the driver or passenger. Instead of dropping the engine directly on the ground, it dipped a few centimeters along the track of the support frame and was stuck by the chassis.
The front edge of the lower guard plate is mounted on the lower frame and can be lowered together with the engine. The trailing edge screw can also be directly detached. The regular guard plate will not affect the engine safety.
There is no need to worry about heat dissipation. The lower guard usually has many small holes. When the car is driving, the air flow enters from the front of the car and flows out through the small holes, which will not affect the heat dissipation of the engine.
'Then I quickly installed a protective shield. How much is it?'
Plastic or resin is the cheapest, light but easy to damage; Aluminum alloy has high hardness, light weight, and the most expensive price; Steel or manganese alloy lower shield has strong impact resistance, but it is relatively heavy.
Often take a bad road to install a manganese steel shield, often driving in the city, plastic shield is enough.
