2. Air flow meter - Wikipedia

   en.wikipedia.org/wiki/Air_flow_meter

   An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

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. Rochester Ramjet - Wikipedia

   en.wikipedia.org/wiki/Rochester_Ramjet

   The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel shutoff on overrun, and idle settings. These measurements are sent via pressure and vacuum signals to the fuel meter, which contains the high-pressure fuel pump and ...

5. Active valve control system - Wikipedia

   en.wikipedia.org/wiki/Active_valve_control_system

   It varies the timing of the valves by using hydraulic oil pressure to rotate the camshaft, known as "phasing", [1] in order to provide optimal valve timing for engine load conditions. The system is closed loop using the camshaft sensors, crankshaft sensors, air flow meter, throttle position as well as oxygen sensors and/or Air-Fuel ratio ...

6. Air flow bench - Wikipedia

   en.wikipedia.org/wiki/Air_flow_bench

   H, pressure drop across test piece in pascals measured by the test pressure manometer d, density of air in kilograms per cubic meter (1.20 kilograms per cubic meter at standard conditions) This represents the highest speed of the air in the flow path of a normally shaped port, at or near the section of minimum area (through the valve seat at ...

7. Jetronic - Wikipedia

   en.wikipedia.org/wiki/Jetronic

   The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure. The control pressure is ...
