At each EGR level, a constant pressure differential of 8 kPa between the intake and exhaust manifold was maintained (with the intake manifold pressure
being higher than the exhaust manifold).
The subsequent exhaust stroke (open outlet vales) and induction stroke (open inlet valves) run at exhaust gas manifold pressure
and intake manifold pressure
The reduction in altitude to 350 m above sea level, which corresponds to the increase of apparent barometric pressure, was simulated with increasing the inlet manifold pressure
of the engine by using a three-lobe rotary blower of the Roots type.
The simulation models for the intake manifold as a differential equation for the manifold pressure
The relatively low manifold pressure
drop with the Original design with small plenums and no plate was the result of the large area for the first distributor, 1/3rd of the inlet manifold area, Equation (2).
One that held a great deal of promise made use of an extra sensor not normally included in production cars that monitored exhaust manifold pressure
The pressure terms are substituted for terms involving the slot flow by rearranging Eq 12 and substituting into Eq 5 to obtain the manifold pressure
Tomorrow's lightplanes will all employ a single, simple power control - as easy to use as a car's accelerator pedal - rather than the current complex system of separate levers to adjust manifold pressure
, fuel mixture, propeller speed, and, in some cases, turbocharger boost.
Pressure sensors -- which consist of silicon membranes etched so thin that changes in external pressure result in changes in the membranes' easily monitored electrical resistance -- now keep track of blood pressure in human patients and manifold pressure
in millions kf cars.
Nearly 30 of them are the MEMS sensors and about five to six are the MEMS pressure sensors which consist mainly of the intake manifold pressure
sensor (MAP Sensor), barometric pressure sensor (BAP Sensor), hydraulic tank sensor, TPMS pressure sensor, airbag pressure sensor and ESC/ESP pressure sensor.
An external source is most often used for air supply which is convenient because the intake manifold pressure
can be regulated independently of exhaust manifold enthalpy.
Under those same high and hot conditions, I'll likely need an extra inch or so of manifold pressure
to hold altitude in various maneuvers, like holding or sliding down an ILS.
