HTF MI Analyst have added a new research study on Title Global (United States, European Union and China) Air Flow Sensors Market Research Report 2019-2025with detailed information of Product Types [, Mass air flow
sensors & Volume air flow sensors], Applications [Aerospace, HVAC & automobiles] & Key Players Such as First Sensor AG, TE Connectivity Corporation, Sensirion AG Switzerland, Honeywell International Inc., Siemens AG, Denso Europe, Degree Controls Inc., Oscium, A Dechnia LLC., Delta OHM & Systec Controls etc.
A building envelope air tightness model can then be built on the basis of the following generic equation that allows mass air flows
to be positive or negative, depending on the air flow direction:
Based on the NOx sensor signal, in combination with an engine mass air flow
sensor and temperature sensor, the necessary urea dosing rate is calculated by the control algorithm.
Engine upgrade projects typically require lowering the equivalence ratio (i.e., a higher mass air flow
rate through the engine for a given mass fuel flow rate) to achieve successively lower [NO.sub.X] emissions.
The engines also yield improved combustion and lower fuel consumption through a closed-loop electronic fuel injection system, electronic ignition, automotive-type oxygen and mass air flow
sensors and a three-way catalytic muffler.
