Optimizing Performance The Critical Timing of RGA Valve Operation

7. Apollo Valves may be soldered with the ball either in the fully open or fully closed position, however fully open is preferable to maximize the heat sink ... Start the flow from the vaporizer into the vacuum pump outlet by opening ball valve MV5 if it is not already open. ... PV2 should then close and PV4 should open ... All EGR does is introduce an inert gas into the combustion chamber at part throttle to reduce combustion temps (reduce NOX) and reduce pumping losses slightly. Residual Gas Analyzer (RGA); RGA manual · Close the NOTCam valve, close the pump valve and switch off the pump. · Switch on the RGA, switch at rear of head, and ... Residual Gas Analysis (RGA) for Integrated Circuits (ICs) is the identification of gaseous components that can be extracted from a microelectronic package ... The valve is normally closed and is opened by the vacuum line running to the valve. If this is the case, then there really is not a need for the EGR block ... In vehicles, the EGR valve, or exhaust gas recirculation valve, is part of the engine management system and is in charge of reintroducing ... Start the truck and let it idle for a minimum of 5-minutes at normal operating temperature. This allows the PCM to learn the EGR valve closed ... 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 ... Mine is just the simple type. It comes off ported vacuum through a TCV valve thing that is inline with the vacuum hose. The TCV is supposed to ...
