Bosch 0280750149 Throttling Device

Overview of the Bosch 0280750149 Throttling Device

The Bosch 0280750149 Throttling Device, also known as a throttle body or actuator, is an essential component in modern internal combustion engines. It regulates airflow into the engine’s intake manifold, enabling precise control of power output and fuel efficiency. Designed for a wide range of applications—from light-duty tractors to off‑road vehicles—this device delivers reliable performance under demanding conditions.

Key Features

• High-Precision Actuation: The throttle body uses an electric motor to move the butterfly valve with exactness, ensuring smooth acceleration and optimal engine response.
• Robust Construction: Made from durable materials that resist corrosion and high temperatures, it maintains integrity in harsh operating environments.
• Compact 40 mm Design: The 40 mm diameter fits a broad range of engines while keeping the overall size minimal for easy installation.
• Drive‑By‑Wire Compatibility: Integrated with electronic throttle control systems, it supports modern drive‑by‑wire (DBW) architectures for improved safety and efficiency.
• Multi-Port Injection Support: Works seamlessly with multi-port injection (MPI) engines, providing precise fuel metering in conjunction with the throttle position sensor.

Technical Specifications

Applications and Compatibility
