The air entrainer above the racer's head is one of the most prominent elements of modern F1 cars.
The air inlet hole located just above the driver's head dictates not only the shape of the bonnet but also the flow of air into the engine itself. The air system regulates the maximum amount of air drawn by the engine, the amount of fuel it can burn, and the level of power that the engine can produce. The air intake seen above the driver's head is the tip of the iceberg throughout the engine's intake system, which is hidden inside the F1 car.

Operation of F1 car air system
High-speed air enters the hole above the driver's head and travels down into a hollow horn-shaped tube that opens at the bottom of the system, where air filter. The air enters the air filter at a pressure higher than atmospheric, which is a result of the dynamic pressure generated by the speed of the racing car. An efficient air system will maintain as much of this dynamic pressure as possible before the air meets the air filter.
The job of an air filter is to prevent all particles or foreign matter, such as sand or grain, from entering the engine. Clean air is ingested into the eight “trumpets” where the flaps are located. If the throttles are open, the air will continue its course and be mixed with fuel. In the end, this mixture of fuel and air passes through the valves into the combustion chamber, where it is ignited by the spark plug and drives the piston down, creating torque.
Why is the air system so important for the operation of the F1 car?
Air – or rather oxygen – is an essential part of the combustion process, and if the system has sufficient airflow at maximum pressure, the amount of torque produced is increased. Ensuring this optimum effect therefore depends on the components of the system. First, the shape of the air intake determines how much air can be introduced into the motor unit. If the supply is too small, the engine will have less power. However, if it is too large, the engine will not be more efficient on a linear scale – more air does not mean more power; This refers to achieving as much overall pressure as possible. In order to achieve this, we must maintain the maximum dynamic pressure created by the speed of the car itself.
The air filter must be very robust at the same time. With a strainer, discontinuance can result in impediment to oxygen flow and a drop in total pressure. Lack of air filters can lead to foreign bodies entering the engine, which can cause permanent damage to the piston and other internal parts of the engine. As a result, engine suppliers swear by the proper “tightness” of the air filter, as well as its ability to hold waste.
