New car to buy back to install the engine guard it
Engine protection has advantages and disadvantages, about the engine protection of the sound is more, the installation of the engine protection plate, you can safely protect the engine, reduce the vehicle fuel consumption; However, some people say that the engine protection plate will affect the engine sinking, affecting the safety of the vehicle, the installation of the metal screen will be enough?
In fact, this is not the case, after all, the protection plate is to be installed in the car, and the protection plate in the installation of the car will have to transfer the force to the body and suspension system, if the original car is only designed to be a piece of plastic protection plate, so the choice of mounting holes is more arbitrary, as long as it can be fixed on the line, a good plastic shroud will be able to do it, and do not need to have a very strong load-bearing capacity.
At this point, it wouldn't be building a building on the beach if you put a gold data protection on it, the engine shroud also controls airflow, allowing more air to flow through the engine, increasing engine cooling, and it's part of the car's aerodynamic package.
It combines with the rest of the chassis cover to form a relatively smooth surface that improves the flatness of the chassis, reduces drag and turbulence in the airflow, lets the air circulate and float faster, and reduces the car's wind resistance coefficient, improving stability at high speeds.
So instead of calling it an engine shroud, automotive engineers call it a "deflector" or "windshield," and some luxury and performance cars wrap the entire underside of the engine compartment tightly, inserting a "shroud" where they can. Some luxury and performance cars wrap the entire underside of the engine compartment tightly, adding the entire chassis where you can insert "fenders" to make it look like a big flat plate, just to give good aerodynamic performance.
The so-called "engine sinking technology" refers to the larger engine displacement in the event of a large vehicle collision. At this time, the release bracket will drop a few centimeters, relying on the steel frame of the engine chassis to block it, preventing it from squeezing into the front row of the main passenger compartment, as far as possible to protect the safety of the personnel.
Car at the factory, the manufacturer has reserved holes for the skid plate, as long as it is a standard skid plate, installed correctly, is not going to affect the engine sinking, now the car, for safety reasons, basically use the engine to lower the design, which is a low-cost products.
But it can effectively avoid damage to the cabin and injury to the passengers in the car, because in a collision, the huge kinetic energy will lead to the engine breaks through the engine compartment into the cockpit, and the engine itself is very important, in the huge kinetic energy, it will cause a very tragic accident, because sinking that engine is a must-have design for almost all modern cars.
Hard plastic resin protection plate is the cheapest engine protection material, hard plastic resin protection plate in addition to effectively preventing small stones hit the engine, but also to keep the engine clean, Pros: the lightest weight, the cheapest price, plasticity, small collision back to the position of the deformation is not large, can withstand gravel and sand damage caused by the chassis.
Disadvantages: poor heat dissipation, low material strength, easy to aging brittle, encountered large stones or the bottom is almost useless, basically need to change the new. Another point to note when installing the engine shroud is the weight, if the engine shroud is too heavy, it will increase the weight of the vehicle, which will increase the fuel consumption of the vehicle and limit the performance.
So if you are going to install an engine guard, it is recommended that you use a lightweight material such as aluminum alloy or reinforced resin, and avoid heavy cast iron plates. As far as slightly more expensive cars are now equipped with skid plates, it can be concluded that this skid plate will never hurt the car, so if this skid plate can be installed, then it is installed, and the price is not expensive.
That said, the shielding plate may not really do much to protect, but you will feel comfortable with it installed. In fact, many people spray armor for peace of mind to add a skid plate I do not know if it is okay, at least more and more cars have skid plates, peace of mind to install one can be installed, install a plastic one. After all, there is still some help!
