2. Hyundai Theta engine - Wikipedia

   en.wikipedia.org/wiki/Hyundai_Theta_engine

   Theta's EMS (engine management system) software is EMS-II from Siemens VDO and the 32-bit PCM (Powertrain Control Module) calculates the amount of intake air by utilizing a contamination-proof hot-film type MAF (mass air flow) sensor. The first version of the Theta Engine had three variants, 1.8L, 2.0L and 2.4L.

3. Mass flow sensor - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_sensor

   A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate 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 with temperature and pressure.

4. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   MAP sensor data can be converted to air mass data by using a second variable coming from an IAT Sensor (intake air temperature sensor). This is called the speed-density method. Engine speed (RPM) is also used to determine where on a look up table to determine fuelling, hence speed-density (engine speed / air density).

6. Hyundai Beta engine - Wikipedia

   en.wikipedia.org/wiki/Hyundai_Beta_engine

   The Hyundai Beta engines are 1.6 L to 2.0 L I4 built in Ulsan, South Korea.. All Beta engines are dual overhead camshaft valvetrain design.The Beta engine uses a direct-acting overhead cam valvetrain arrangement which places the camshaft in the cylinder head above the pistons and combustion chamber and operates the valve tappets/lifters directly.

7. Mass flow controller - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_controller

   All mass flow controllers have an inlet port, an outlet port, a mass flow sensor and a proportional control valve. The MFC is fitted with a closed loop control system which is given an input signal by the operator (or an external circuit/computer) that it compares to the value from the mass flow sensor and adjusts the proportional valve ...
