"How is the engine compartment cover so thin, I feel that a slight heavy object will sink down", "The manufacturer is also too cutting corners", "The quality of this product is not good", etc., these complaints about the engine compartment cover should be often heard by everyone.
Many people will also wonder, why is this engine compartment cover so soft? Did the manufacturer cut corners?
Many people think that the car, should be the harder the quality of the more resistant to manufacturing, today Meow brother will take you to discuss, to see if the engine compartment cover is really harder the safer.
structure
Our common car engine is basically front-mounted, and a car is the engine compartment, cockpit, and luggage compartment from beginning to end.
The engine compartment is located at the forefront of its function can not be ignored, the engine compartment cover can keep the engine compartment clean, prevent the road area water, dust and other debris into the engine compartment, so that the engine can work normally;
Prevent the car from hitting the engine with sand and hard objects rolled up due to tire crushing during driving, so as to ensure the integrity of the engine; it can also prevent bumps and bumps on the road surface and hard objects from scratching the engine.
From the perspective of protecting the engine, the hardness of the cover plate seems to be a little harder, which is also the level of most thinking. But does that mean the harder the better? Not necessarily.
cause
First of all, vibration is inevitable when the engine is working, if your engine compartment cover is relatively the one hand, it will directly transmit vibration to the cab, resulting in a great reduction in comfort.
Especially for passengers in the front row, if you drive a long distance, your body may not be able to stand it.
On the other hand, the cover plate is too hard and easy to produce resonance and abnormal sound, which has a relatively large impact on the comfort of the ride and the life of the mechanical hardware.
Secondly, when a frontal impact accident occurs, the impact is transmitted from the front engine compartment to the back cockpit, if your engine compartment cover is too strong at this time, the impact can not hit the cover or sink, then the cover will transmit the impact to the cab, which is equivalent to causing secondary damage to the cab.
In layman's terms, if the engine cover is too strong, there is no way to absorb the impact generated by the impact, and it will also transmit injuries and aggravate the severity of the accident.
To the cockpit it is like a flying knife coming sideways, and to pedestrians it is like a sharp blade. When an accident occurs, it not only causes economic losses, but also greatly improves the injury of personnel.
summary
On the whole, the engine canopy is by no means the harder the better, every design will have its design reason, the harder and safer depends on what angle to stand.
If someone says, "The engine cover is too soft, it's not safe to sink down when you press it," then you can tell him that this is specially designed to absorb energy to protect pedestrians and passengers.
