Mass flow sensor Wikipedia

+

A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuelinjected internal combustion engine.. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient ...
