Throttle control systems are mechanisms that regulate the amount of air or fuel entering an engine, which directly affects its power output. These systems can be mechanical, using cables and levers, or electronic, utilizing sensors and actuators to optimize performance. In modern vehicles, electronic throttle control (ETC) is common, allowing for precise adjustments based on driver input and engine conditions. This technology enhances fuel efficiency, reduces emissions, and improves overall vehicle responsiveness, making it a crucial component in contemporary automotive design.
