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.
The MAF sensor is an electronic sensor that sends a signal to the engine computer, which then uses the measurements to help calculate fuel delivery and spark timing. In most applications, the MAF sensor utilizes an electrically charged wire to determine the amount of airflow entering the air intake.This wire produces an electrical voltage, based on airflow, and sends it to the engine computer, which then uses the information to adjust spark timing, fuel delivery and spark advance.n most applications, the MAF sensor utilizes an electrically charged wire to determine the amount of airflow entering the air intake.
