A1611413025 Benz M276 Series Of Engines Throttle Body Assembly

1. Vehicle Compatibility Table

The part number A1611413025 is primarily compatible with a wide range of Mercedes-Benz models equipped with the M276 series of engines, which was a very commonly used engine.

2. Product Introduction (Features)

This throttle body assembly is a critical component of the Electronic Throttle Control (ETC) system, designed specifically for Mercedes-Benz vehicles. Its main features include:

• Precise Electronic Control: Utilizes electronic sensors and an electric motor, replacing older cable-operated throttles for more precise control and faster response.

• High-Strength Materials: The body is typically made from aluminum alloy, ensuring lightness and good heat dissipation. The throttle plate (butterfly valve) is made from high-strength engineering plastic or specially coated metal for durability and smooth operation.

• Integrated Design: The assembly integrates the Throttle Position Sensor (TPS) and the actuator motor internally. It's a unit designed for easy replacement, often plug-and-play without need for adjustment.

• OEM-Quality: The part number A1611413025 generally represents a high-quality replacement part that meets original Mercedes-Benz standards, ensuring perfect compatibility with the vehicle's ECU and performance.

• Core Functional Component: Acts as the "throat" of the engine's intake system, directly controlling the volume of air entering the engine.

3. Technology & Principle

• Technology Type: Electronic Throttle Body (ETB), also known as "Drive-by-Wire."

• Working Principle:

  1. When you press the accelerator pedal, the pedal position sensor sends a signal to the Engine Control Unit (ECU).

  2. The ECU calculates the optimal throttle opening angle based on a comprehensive analysis of current engine speed, load, temperature, and other data.

  3. The ECU then sends a command to the miniature motor inside the throttle body. This motor drives a gear mechanism to precisely rotate the throttle plate, opening or closing the air intake passage.

  4. A dual-track throttle position sensor mounted on the throttle shaft continuously feeds the actual throttle plate angle back to the ECU, forming a closed-loop control system to ensure accurate operation.
