When a poppet valve is opened, the output capacity of a system changes based on the flow characteristics introduced by the opening of the valve. Specifically, opening a poppet valve allows air to flow more freely through the system, which means that the output capacity is not simply reduced. In fact, when the valve is opened, it creates a pathway for additional air to flow, potentially increasing the flow rate depending on the system's overall design and operational conditions.

The dynamics involved with poppet valves typically include the concept of back pressure and flow resistance. When a poppet valve is closed, the system may be under higher pressure, which implies that when it opens, there is a reduced resistance to flow. This leads to an increase in output capacity as the air can pass through more liberally, thus enhancing the volumetric output for that system.

Therefore, the nature of the poppet valve’s function does not support the idea that output capacity is consistently reduced; rather, it is more aligned with increased flow and capacity as the valve opens up opportunities for better air movement in the system.
