Valve Timing Unveiled A Guide to RGA Valve Opening and Closing

Open the valve. This will momentarily raise the vacuum pressure. When the pressure stabilizes, close the valve. The RGA should now be kept under high vacuum ... The EGR-valve is closed when uegr = 0 % and open when uegr = 100 %. The VGT is closed when uvgt = 0 % and open when uvgt = 100 %. 1.4 Measurements. To tune ... However, in the dual DP configuration, when the sample valve is closed the hydro- ... Every operation that takes place (valve open or close, pumps turned on or ... If I am letting my truck idle to cool down after a long drive, the valve will close (EGR Percent @ 0) after about 3 mins and I can hear a change ... ... can be chosen to detect within milliseconds when a valve has opened or closed on the tool. This provides Vision 2000-B systems with the flexibility to fully ... The fluid pressure moves the upstream disc off its seat, and the force is transferred onto the downstream disc, thereby ensuring a tight shut-off. The high ... Low speed and city driving are when the EGR valve is open the most. The least would happen at freeway speeds. After that, the idle speed valve is coming out again and a used one is going back in :) ... According to alldatapro, the IACV can open over ... I'm trying to digest how the EGR control strategy works to identify if the EGR motor needs to be replaced. I can't think of anything else. Mine is just the simple type.
