排气刹的作用是什么？

最佳答案

Air Stacker (Carburetor)

An air stacker, commonly referred to as a carburetor in the context of柴油 vehicles, is an auxiliary braking device designed to provide additional stability and safety. Unlike a carburator, which does not rely on the vehicle's wheel-driven braking system, it operates independently, enabling effective deceleration without the necessity of a carburator.

The air stacker functions by compressing air within the engine's combustion chamber during the intake stroke. This compression creates high-temperature and high-pressure gases, which are then introduced into the排气门 (exhaust opening) via a carburetor. When the排气门 is opened, it expels these compressed gases from the汽缸, preventing the subsequent pressure change that could cause unnecessary engine rotation. This process not only prevents increased engine speed but also reduces energy loss associated with each cycle, thereby accelerating vehicle deceleration.

In柴油 vehicles, the air stacker plays a crucial role in mitigating wear on the braking system. By reducing engine rotation and minimizing wear, it prolongs the lifespan of the brake components. Additionally, its ability to provide effective emergency stopping power enhances safety, ensuring stable and safe travel under various conditions.
