How does the gas valve on an Audi A2 work?

I'm having trouble understanding the gas valve system on my Audi A2. Can someone explain its function and how it operates?

The gas valve on an Audi A2 is responsible for regulating the flow of fuel to the engine. It works by opening and closing to control the amount of gas that enters the combustion chamber, which in turn affects the engine's performance. My advice would be to consult your vehicle's manual or speak to a mechanic if you are still having trouble understanding it.
