throttle
The Spanish word 'acelerador' translates to 'throttle' in English. In the context of a vehicle, a throttle is a device controlling the flow of fuel or power to an engine. When you press the accelerator pedal with your foot, it opens the throttle, allowing more air into the engine. The engine control unit (ECU) then increases the amount of fuel injected into the engine, which increases power output. Hence, 'acelerador' is used in Spanish in the context of an engine's acceleration mechanism.
