The working principle of New Mass Air Flow Sensor MAF for Mercedes-Benz

In order to obtain the best concentration of the mixture under various operating conditions, the electronically controlled gasoline injection engine must accurately measure the amount of air sucked into the engine at each moment, which is the main basis for the ECU to calculate (control) the fuel injection amount. . If the New Mass Air Flow Sensor MAF for Mercedes-Benz  fails, the ECU cannot obtain the correct intake signal, and the fuel injection amount cannot be controlled normally, which will cause the mixture to be too rich or too lean, which will cause the engine to run abnormally. There are many types of air flow sensors for electronically controlled gasoline injection systems. According to their structure, common air flow sensors can be divided into blade (wing plate) type, core type, hot wire type, hot film type, Karman scroll type, etc. Kind. blade (wing plate) type, core type, hot wire type, hot film type, Karman scroll type, etc. Kind.
