Business services is a general term that describes work that supports a business but does not produce a tangible commodity. Information technology (IT) is an important business service that supports many other business services such as procurement, shipping and finance.
A mass airflow sensor. A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected 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 as it expands and contracts with temperature and pressure.
A Mass Airflow Sensor (MAF) is one of the components of a car electronic fuel injection system. A mass air flow sensor is installed between the air filter and the intake manifold of the engine. The main job of the mass air flow sensor is to measure the amount of air entering the engine or air flow.Often an intake air temperature sensor (IAT) is also installed within the mass air flow sensor. There are few types of air flow sensors, however most modern cars use a hot-wire type.Let's see how it works.he main job of the mass air flow sensor is to measure the amount of air entering the engine or air flow.
