During the filling, while the membrane is pulled down, the outlet valve remains closed and the
inlet valve opens when the underpressure in the pumping chamber reaches the
inlet valve opening threshold.
As we can be observed, the incoming air is pushed towards the corners given the injector plate is placed in the direction of flow, and as a result the velocity rises in inlet corners and therefore the velocity of
inlet valves is obtained in 195 m/s as well as the velocity of outlet valve is obtained in 93 m/s because input flow can only be entered from the corners of plate opposite the injector, thus high velocity in
inlet valve causes to rotate the flow inside chamber (figure 10).
The breakthrough of the new Multiair engines is the way they control the movement of the engine's
inlet valves, whose job is to control the amount of fuel and air mixture that enters the combustion chamber.
The flow through the
inlet valve discharges into the cylinder as a jet that separates from the seating faces of valve and seat for specific lift conditions [3].
Another likely cause is a clogged inlet screen or faulty
inlet valve. Photos 4 and 5 show how to clean the screen or replace the valve.
In addition, the redesigned catalyst pump includes a soft-stop
inlet valve that allows for a positive sealing surface with a stop to maintain flow and reduce inlet ball wear.
Other features include: heavy-duty tubular construction with Steel-It[R] epoxy finish, an 8" diameter
inlet valve with bulk/dribble controls for accurate weighments, and a bag inflation system to remove folds in bags for maximum fill volume and bag stability.
Features are, sintered stainless steel 316L falters at the process
inlet valve, stainless steel diaphragm type shut off valves which are optimised for low internal volumes with on/off position indicators and have a stainless steel regulator with highly precise control accuracy.
With traditional cold air intakes, as the RPM increases,
inlet valve opening increases while the inlet tract length remains constant.
The
inlet valve, when set to the blowdown position, isolates the trap for service.
