The BMW Part Hot-Film Air Mass Meter is important for your car’s engine. It measures how much air comes into the engine. This helps the computer that controls the engine figure out how much fuel to use.
By getting this just right, it keeps the engine running smoothly, reduces pollution, and makes the car perform better.
The BMW Part hot-film air mass meter 13627520519 is a sophisticated component designed to measure the mass of air entering the engine. Here are the technical aspects:
Housing: The sensor is housed in a durable casing that protects the internal components.
Measuring Cell: At the core of the sensor is a measuring cell made from a semiconductor substrate. This cell includes a diaphragm with temperature-sensitive resistors.
Evaluation Electronics: Integrated within the sensor is an evaluation electronics module, which processes the data from the measuring cell.
Flow Rectifier: The sensor includes a flow rectifier, typically a combination of plastic and wire mesh, to ensure uniform airflow over the measuring cell.
Air Flow Measurement: Air flows over the heated sensor membrane in the measuring cell.
The temperature difference between two defined measurement fields on the membrane is recorded by resistors.
Temperature Difference: As the air current strength varies, the temperature difference between the measurement fields changes.
Calculation and Transmission: An integrated electronic module calculates the air mass from this temperature difference and transmits the result to the engine control unit (ECU).
High Precision: The hot-film air mass meter provides highly accurate measurements, ensuring precise air-fuel mixture control.
Adaptability: It can adapt to various operating conditions, maintaining accuracy throughout its service life.
Integration: The modular design allows for the integration of additional sensors, such as humidity, pressure, and temperature sensors.
Reduced Pulsation Error: The sensor’s design minimizes pulsation errors, improving measurement precision.
Optimal Air-Fuel Ratio: By providing accurate air mass data, the sensor ensures the engine receives the optimal air-fuel mixture, leading to efficient combustion.
Enhanced Fuel Efficiency: Precise control over the air-fuel ratio results in better fuel efficiency and reduced emissions.
Improved Performance: Accurate air mass measurement contributes to consistent engine performance and responsiveness.
