Perfect English! But your explanation is good for people, who have brains

[Cathay]

Thank you for your nice explanation.Well done.

How neutral position is possible when there is always high oil pressure acting on the hydraulic springs near the feed back sensor?? Can you please explain??

[Sea_Mariner]

What abt the electrical signal 4mA to 20mA.?
If u would tell us particularly that at 4mA which valve will open and at 20mA which valve will open.. this would be a great appreciation

Need Help!!
The problem faced is that the pump plunger stroke of one unit is quite low compared to the other units and thus the exhaust temp/power output is low for that unit at low rpm of the of the engine (less than half ahead).
But at higher rpm (ahove half Ahead) the plunger stroke becomes ok and is about the same as othe units with not much deviation in exhaust temp.
Can you advise what is at fault FIVA or booster ?🙏

The cross-sectional colourful view of FIVA as shown, a constant supply of hydraulic oil is fed to the pilot actuator. Well, then where does the pilot actuator apply pressure to move the spool? There must be an actuating pressure at one end corresponding to the demand, say fuel injection...then over a certain crank angle, the spool will be moved by being activated from the other end by pilot actuator. Isn't it? The supply in red colour simultaneously showing supply to the pilot actuator at the same time to the other end of the spool. How come possible?
The animated working of the spool is easy to make out, however in reality after viewing the actual block of FIVA (Bottom part) it's quite confusing and difficult to identify the dedicated ports.

Pls tell about in this video abt fail safe method also

[hiteshkalal]

Sir please make video on RT-FLEX engine

[tonygao]

question：
1. why the right side always be pressed by oil
2. how to keep in neutral position

[querubinyngojojr]

If to change the FIVA valve, what connection to disconnect to MPC.Thanks if possible with video.

[steveobrien]

Is there a backup if the cylinder control unit fails???

Can you add text here, I can't hear some words
