luftdrossel

Luftdrossel, meaning "air throttle" in German, refers to a device or mechanism used to control the flow of air in a system. These devices are commonly found in internal combustion engines, particularly in older carburetor systems, where they regulate the amount of air entering the combustion chamber. This controlled air intake, in conjunction with fuel, is crucial for achieving the correct air-fuel mixture required for efficient engine operation.

In practical terms, the luftdrossel is often a butterfly valve or a similar adjustable aperture. When the driver presses the accelerator pedal, it typically operates a linkage that opens the luftdrossel, allowing more air into the engine. Conversely, when the pedal is released, the luftdrossel closes, restricting airflow and reducing engine speed. Beyond automotive applications, luftdrossel mechanisms can be utilized in various industrial processes, HVAC systems, and pneumatic controls where precise regulation of air volume is necessary. The term emphasizes the function of throttling or restricting air, distinguishing it from devices that solely direct airflow.
