Which component senses atmospheric pressure and adjusts the throttle butterfly in a supercharged engine?

Explanation:
An aneroid capsule senses atmospheric pressure and automatically adjusts the throttle butterfly in a supercharged engine. The capsule is a sealed chamber with a flexible diaphragm that expands or contracts as outside air pressure changes. Its movement is linked to the throttle mechanism, so as altitude changes and ambient pressure falls, the capsule shifts the throttle to maintain proper air flow and boost. This automatic adjustment is what keeps the engine breathing correctly at different altitudes. The other parts mentioned don’t sense ambient pressure or control the throttle: fuel injectors control fuel flow, spark plugs handle ignition, and the oil pump circulates lubrication.
