Modification trends by changing the exterior of the car, the modifiers are increasingly loved. Sometimes we as car owners want to modify the exterior of our car so that it has its own characteristics that become the identity of our car. One thing that is usually done in car modification is by adding accessories to certain parts. For example, installing a diffuser on the bumper of a car.
Function of the Diffuser
The diffuser itself has a special function, where usually this component can be found in racing cars attached to the bottom of the car bumper , both at the front and rear. The main function of the diffuser is basically to add aerodynamic value to the car when traveling at high speed.
The design of the diffuser will determine the velocity of air flowing through the car. The faster the air flows, the lower the air pressure under the car, which gives the car high downforce . This system will also determine the traction of the racing car on the track, and also the speed of the car. The system works similar to an airplane wing or a car rear spoiler .
In the world of racing, the use of a diffuser is adjusted to the size that has been adjusted by the FIA. From the results of the FIA study revealed that the use of a wider diffuser can make the car half a second faster per lap in races. When the car is driving on the highway, air at high speed flows under the car with a low pressure force. When low pressure air reaches the rear of the car, through the diffuser which is behind the car, it expands in the expansion space in the body of the car.
However, in its development, diffusers are also widely installed in daily cars with the aim of more to the appearance or cosmetics of the car body. Installation requires several conditions that must be met in order for the diffuser to work properly, namely the vehicle must go fast enough.
For those of you who like speed and are accustomed to running at speeds above 100km / hour. Diffusers can be designed according to your needs, but what must also be considered is the aesthetic value. Diffusers are generally installed on flat cars and usually use a diffuser for cars that are equipped with a body kit.
Diffuser Parts In Cars
- Front Splitter
On the front bumper of the car, the diffuser is known as the Front Splitter. Using a front splitter is a cool way to give the lower end of the front bumper of our beloved car a more stylish look. For cars with a low suspension, front lip is usually added to emphasize the character of the car. The front splitter is also functional, because it functions to support aerodynamic functions, especially when the car is driving at high speed.
In addition, diffusers are also commonly found on the side of the front of the car. That part is commonly known as the canard . This part serves to help control the spread of air separated by the front splitter .
The addition of a canard to a car is indeed a modification that is often underestimated by most people. In fact, besides functioning to decorate the car, the canard also adds other functions to the car. Because in principle, the canard helps rearrange the direction of the air on the side of the car, where the air will be stored and allowed to flow to all parts of the car.
- Rear Diffuser
The rear diffuser is one part of the body part that is attached to the rear bumper of the vehicle. Interestingly, the diffuser itself has a special function, which usually this component can be found in racing cars.
Diffusers are basically used to add aerodynamic value when traveling at high speeds. However, because this component is increasingly in demand by car enthusiasts, many new car manufacturers are also using a rear diffuser as part of the body part of standard cars.
Use of a Diffuser on a Car Daily
If you are a modifier and are interested in using a diffuser on a daily car, this is commonplace, regardless of whether the daily car you use has high performance or not. Modifying the exterior in addition to using a body kit, the use of a diffuser has also been increasingly adapted.
This is also apart from the many aftermarket brands that issue diffuser variants for various types of cars. Like the aftermarket brands Varis, Voltex, Kansai, APR, Novitec, Liberty Walk and also Rocket Bunny which issued a body kit variant with a diffuser as part of the body kit used.
It’s good before you decide to use a diffuser in a car, you have to find a complete reference for what kind of diffuser is suitable to be installed on your car. Don’t be careless when choosing the shape of the diffuser you want to use because it will ruin the overall aesthetics of your modified appearance.
The use of a diffuser must also be motivated by the modification concept that you are carrying. If the concept used is street racing and JDM, it seems appropriate to use a diffuser as an addition to the flow of modification. But it is different if you apply the concept of elegance or stance, it seems less suitable if you add a diffuser.
Installing a diffuser also cannot be done carelessly, discuss it first with a workshop that is used to installing the part. Because the diffuser installation also has to measure and do the fitting process first.
So that the diffuser that you have purchased matches the shape of the existing bumper , make sure you don’t let the nut / diffuser hook onto the bumper not meet. Make sure the shape also matches the shape of the bumper so that the diffuser looks match in ‘not colliding with the bumper shape of your car.
