MAF sensor in a 2006-2015 automotive diesel engine. 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 ...
A fuel-injected engine may alternatively use a mass airflow sensor (MAF sensor) to detect the intake airflow. A typical naturally aspirated engine configuration employs one or the other, whereas forced induction engines typically use both; a MAF sensor on the Cold Air Intake leading to the turbo and a MAP sensor on the intake tract post- turbo ...
The MAF is a component in a vehicle's intake system through which air flows past a wire that is heated by an electric current. The airflow cools the wire, enabling the MAF to calculate the mass of airflow into the 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.
It produces 90 kW (122 PS; 121 hp) of power at 5500 rpm and 170 N⋅m (125 lb⋅ft) at 4200 rpm. Starting with 1996 it has a variant called the M111.921 [2] which has a MAF (Mass Air Flow)-sensor instead of MAP-sensor on the first one, and using ECU instead of PMS. Applications: 1993–2000 C 180 (W202)
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 ...
In many late model automobiles, a Mass Airflow (MAF) sensor is used to accurately determine the mass flow rate of intake air used in the internal combustion engine. Many such mass flow sensors use a heated element and a downstream temperature sensor to indicate the air flowrate. Other sensors use a spring-loaded vane.
An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel. It is used primarily for testing the intake and exhaust ports of cylinder heads of internal combustion engines .
