Szívónyomás

Szívónyomás, which translates to "suction pressure" or "intake pressure" in English, refers to the pressure within a system during its suction or intake phase. This concept is particularly relevant in the context of pumps and engines. In a pump, szívónyomás describes the pressure at the inlet port as the pump attempts to draw fluid into its chamber. A lower szívónyomás, meaning a more significant drop in pressure from the surrounding environment, indicates a greater pull by the pump. Conversely, a higher szívónyomás suggests less resistance to flow.

In internal combustion engines, szívónyomás relates to the pressure within the intake manifold during the intake stroke of a piston. As the piston moves down, it creates a partial vacuum, drawing the air-fuel mixture into the cylinder. The szívónyomás in this scenario is typically below atmospheric pressure. Monitoring szívónyomás can provide insights into engine performance, such as the condition of the intake valves or potential air leaks. In both pump and engine applications, understanding and managing szívónyomás is crucial for efficient operation and performance optimization.
