Product Overview

    These part numbers (e.g., 13548624190) are for the Throttle Body components compatible with various BMW models. The throttle body is a critical electronically controlled component in the engine's air intake system. It acts as the engine's "throat," controlling the airflow entering the engine, which directly impacts engine power output, fuel economy, and smooth operation.

Key Features

1. Electronic Control: Modern BMWs use electronic throttle bodies, directly controlled by the engine computer (DME) for precise and rapid response.

2. Precision Engineering: The internal throttle plate and shaft are manufactured to high-precision tolerances, ensuring accurate airflow control at all opening angles.

3. Integrated Design: Typically integrates a position sensor and an actuator motor for closed-loop control, ensuring the plate position matches the computer's command.

4. Durable Materials: The body is often made from aluminum for lightweight and heat resistance. The throttle plate features low-friction, durable coatings.

5. Plug-and-Play: Designed as direct replacements for OEM parts for full compatibility. Installation usually requires a matching/adaptation procedure.

Primary Uses

• Regulate Airflow: Precisely controls the amount of air entering the engine based on the driver's accelerator pedal input and various engine operating conditions (e.g., cold start, acceleration, deceleration).

• Maintain Idle Stability: Fine-tunes the throttle opening at idle to keep the engine running smoothly.

• Deliver Power Demand: Translates the driver's acceleration demand into actual engine power.

• Aid Emission Control: Works in concert with the entire engine management system to help reduce harmful emissions.

Production Process

Throttle body manufacturing is a precision process, primarily involving:

1. Die Casting/Machining: The aluminum body is die-cast and then precision-machined using CNC machines to ensure smooth and accurate mounting surfaces and air passages.

2. Throttle Plate Manufacturing: The plate is stamped or forged and treated with surface coatings to reduce friction and prevent carbon buildup.

3. Assembly: The drive motor, gear assembly, return spring, and sensors are assembled into the main body. This is often an automated or semi-automated process in a cleanroom environment.

4. Functional Testing: Each unit undergoes rigorous testing for electrical performance and mechanical operation before leaving the factory.
