Ram Air is a system used in vehicles, particularly in aircraft and high-performance cars, to enhance engine performance. It works by directing outside air into the engine at higher speeds, increasing the amount of oxygen available for combustion. This can lead to improved power output and efficiency. In aircraft, Ram Air is often utilized in the design of the engine intake. As the aircraft moves forward, the speed of the air increases, creating a pressure difference that forces more air into the engine. This principle helps maintain optimal performance at various altitudes and speeds.
