ilmamassamittari

Ilmamassamittari, also known as a mass airflow sensor (MAF sensor), is a crucial component in modern internal combustion engines. Its primary function is to measure the amount of air entering the engine. This information is then relayed to the engine control unit (ECU), which uses it to calculate the precise amount of fuel to inject into the cylinders for optimal combustion.

There are two main types of MAF sensors: hot-wire and hot-film. The hot-wire type uses a heated wire that is cooled by the incoming air. The ECU measures the amount of current needed to keep the wire at a constant temperature, which is directly proportional to the airflow. The hot-film type works similarly, but uses a heated film instead of a wire.

A faulty MAF sensor can lead to a variety of engine performance issues. These can include rough idling, poor acceleration, decreased fuel economy, and illuminated check engine lights. In some cases, a malfunctioning MAF sensor can even cause the engine to stall. Regular maintenance and diagnostics can help identify and address MAF sensor problems before they become severe. Cleaning the MAF sensor with specialized MAF cleaner is a common troubleshooting step.
