Whether the deflector is aesthetical or to reduce wind resistance

Reduce the drag coefficient of the tractor to improve fuel economy

There are numerous factors that affect the fuel consumption of a tractor, but people often focus their attention on the three major components of the vehicle. As a result, they pay less attention to the fuel consumption caused by air resistance when the truck is traveling at high speed. Air resistance accounts for a very large proportion of the total driving resistance, far exceeding the resistance caused by other factors. Thus, it can be seen that wind resistance has a significant impact on fuel consumption.

According to an experimental data from abroad, when the operating speed of a truck is 50 kilometers per hour, installing air deflector components can effectively reduce the vehicle's wind resistance coefficient and improve its fuel economy. Therefore, the rational use of air deflector components to reduce wind resistance should be taken seriously by everyone, which is of great help in reducing the fuel consumption of trucks.

Is the deflector for aesthetic purposes or to reduce wind resistance

For a truck, reducing the drag coefficient of the cab is not an easy task as it not only needs to meet the comfort requirements brought by the spacious cab but also ensure the safety of the driver and passengers in the event of a collision. After years of research and development, truck manufacturers have changed the previous square-head design elements of trucks and started to adopt streamlined designs for the cab to achieve a lower coefficient of drag. In addition, by installing a deflector on the cab, the exterior design of the cab can be made more fluid, thereby reducing the drag coefficient of the tractor. When the vehicle is in motion, it can reduce air resistance and improve its fuel economy.

What are the deflector covers for trucks that can reduce wind resistance?
The main deflector components used on trucks include: the top deflector of the cab, the side deflector of the cab, and the side skirts of the vehicle body, etc. When these deflector components are used in conjunction, they can effectively reduce the vehicle's drag coefficient and improve its fuel economy when the tractor is in motion.

Truck drivers have insufficient understanding of the deflector

In China, the installation of a tractor deflector is not mandatory. Whether a vehicle is equipped with a deflector is entirely up to the owner's choice. Due to issues such as price, vehicle height and user perception, many people do not choose to be equipped with a fairing. As the understanding of vehicles among a large number of car owners has increased, many people now recognize the importance of the deflector of the tractor and choose to install it later.

Many people are not very familiar with aerodynamics and think that installing it can play a role in guiding the flow and reduce the vehicle's fuel consumption. They do not adjust the height of the deflector according to the height of the trailer. In this case, although a deflector has been installed, the wind resistance the entire vehicle encounters during operation is still considerable. The deflector merely serves a decorative purpose, making the appearance of the tractor more attractive, but it does not bring about the best fuel economy for the entire vehicle transportation. Therefore, it is also very important to adjust the height of the top deflector correctly.

Some people still believe that the height of their semi-trailer is lower than that of the tractor, and installing a deflector will increase the overall height of the vehicle. This not only affects the vehicle's passability but also increases the windward area of the tractor, and thus cannot improve the vehicle's fuel economy. This statement is obviously incorrect.

Installing and using the deflector correctly can help you save more money

When installing a vehicle deflector, the matching degree between the tractor and the semi-trailer should be taken into account. Specifically, the height of the deflector on the top of the cab should be adjusted to be comparable to that of the semi-trailer, changing the direction of the wind to prevent it from hitting the cargo box and reducing the driving resistance caused by the chaotic airflow between the tractor and the semi-trailer. There will be a certain gap between the tractor and the semi-trailer. Installing a side deflector of the cab ensures the smooth flow of air and reduces the wind resistance caused by the lateral wind.

Some people may think that some tractors have side skirts on both sides, and the side skirts are not merely for decorating the vehicle. When the vehicle is in motion, the side skirts can make the airflow direction on both sides of the tractor better, reduce air turbulence, and achieve the purpose of lowering wind resistance and improving the fuel economy of the vehicle. The deflector makes the entire vehicle look more proportionally harmonious and aesthetically pleasing, making the vehicle more aerodynamic. It reduces wind resistance during high-speed driving and can achieve better fuel economy. Therefore, it is recommended that all car owners choose a deflector when purchasing a tractor. Because the deflector is not only for decoration, but also can help you save more money if used well!
