Bosch 0280750467 Throttling Device

Bosch 0280750467 Throttling Device

The Bosch 0280750467 Throttling Device is a precision‑engineered component designed to regulate airflow into an internal combustion engine. It serves as the heart of the vehicle’s throttle system, translating driver input into controlled air intake for optimal power delivery and fuel efficiency.

Key Functional Characteristics

• Airflow Regulation: The device modulates the volume of air entering the combustion chamber by adjusting a valve that opens or closes in response to throttle position signals.
• High‑Temperature Resistance: Constructed from advanced alloys, it withstands operating temperatures exceeding 400 °C without deformation or loss of performance.
• Rapid Response: Designed for quick actuation, ensuring minimal lag between driver input and engine response—critical for high‑performance and luxury vehicles.
• Durable Seals: Equipped with premium O‑rings that maintain a tight seal under varying pressure conditions, preventing air leaks that could compromise efficiency.

Engineering Design & Materials

The throttling device features a compact cylindrical housing that houses the valve mechanism. The valve itself is a rotary or slide‑type actuator, depending on the specific application, and is driven by an electric motor or vacuum system integrated into the vehicle’s electronic throttle control (ETC) architecture.

Materials used include:

• Stainless Steel Alloy: Provides corrosion resistance and structural integrity.
• High‑Temperature Plastic Components: Reduce weight while maintaining thermal stability.
• Advanced Ceramic Coatings: Protect critical surfaces from wear and oxidation.

Compatibility Overview

The Bosch 0280750467 is engineered to fit a wide range of Mercedes‑Benz models, including but not limited to:

• C‑Class (CL203, W204, S204)
• CLK Series (A208, C208, A209, C209)
• E‑Class (W211, W212)
• S‑Class (C215, C216)
• SLK and SLK‑R Series (R170, R171)
• Sprinter Van (W906, 5‑T, 3‑T)

Its universal design allows seamless integration with both mechanical and electronic throttle systems across these platforms.

Installation & Maintenance Guidelines

1. Removal: Disconnect the battery to prevent accidental engine start. Carefully detach the throttle linkage or electronic connector, noting the orientation of any sensors.
2. Inspection: Check for wear on seals and valve surfaces. Replace any damaged components before reassembly.
3. Installation: Align the device with the engine’s intake manifold, ensuring proper seating of all mounting flanges. Reconnect electrical connectors or vacuum lines as specified by the vehicle’s service manual.
4. Tuning: After installation, perform a throttle response calibration using an OBD‑II diagnostic tool to confirm correct sensor mapping and actuator behavior.

Performance Benefits

• Improved Throttle Response: The device’s rapid actuation reduces lag, providing drivers with immediate power delivery.
• Enhanced Fuel Efficiency: Precise airflow control optimizes the air‑fuel mixture, lowering fuel consumption and emissions.
• Reduced Engine Wear: By maintaining consistent airflow, it minimizes combustion irregularities that could lead to engine knock or component fatigue.
