Role of Part 3931527 Throttle Lever in Engine Systems

The Throttle Lever, identified by part number 3931527, is an integral component within the throttle kit, designed to modulate the engine’s power output by controlling the airflow into the engine. This lever is directly connected to the throttle body, which is a pivotal part of the engine’s air intake system.

When the throttle lever is actuated, either manually by the operator or through an automated system, it adjusts the position of the throttle plate within the throttle body. This action regulates the amount of air that can enter the engine, which in turn affects the fuel mixture and the engine’s RPM (revolutions per minute).

The throttle lever’s interaction with the throttle body is essential for maintaining the desired engine performance across various operational conditions. It ensures that the engine receives the appropriate amount of air for combustion, which is necessary for efficient operation and power delivery.

In automated systems, the throttle lever may be connected to an electronic control unit (ECU) that uses sensors to monitor engine conditions and adjust the throttle position accordingly. This integration allows for precise control over the engine’s performance, enhancing both efficiency and responsiveness.

Overall, the throttle lever plays a significant role in the coordination between the engine’s air intake system and its power output, ensuring that the engine operates within its optimal parameters ¹³.
