Precision Air Flow Meters for Optimal Fuel Injection

An air flow meter is a crucial component in automotive systems, tasked with measuring the volume or mass of air entering the engine, typically in units of grams per second (g/s). This data is fundamental for the Engine Control Unit (ECU) to calculate the precise amount of fuel to inject, based on the air-fuel ratio principle (mass of air flow × air-fuel ratio = mass of fuel). There are mainly two types: the hot-wire air flow meter, which determines air velocity by measuring the cooling rate of a heated wire, and the hot-film air flow meter. The latter, employing a planar hot-film chip, offers enhanced reliability compared to its hot-wire counterpart. A highly accurate air flow meter ensures optimal combustion within the engine, improving fuel efficiency, boosting power output, and reducing harmful emissions.
