Examples included a corroded fuel manifold
valve on a Viking that had been sitting for nearly two years and an oil filter adapter that was installed incorrectly causing an oil leak that lead to oil exhaustion and a seized engine.
The Atlanta Journal-Constitution reports (http://on-ajc.com/2cem3Cj ) that the National Transportation Safety Board on Tuesday announced that an investigation revealed that the fuel manifold
wasn't operating normally and was contaminated by debris.
This requires the pressure in the fuel manifold
to be controlled (changed) by the governor in order to control speed as the load on the engine changes.
The fuel manifold
valve was removed and disassembled.
Valve Viewer A/F will allow setup of all user-definable set points in Continental Controls' ECV 5 and EGC 2 products, and will monitor such key data points as: oxygen sensor set point and feedback, valve position, fuel manifold
pressure, and whether the controller is operating in the default pressure control mode or in the [O.sub.2] air-fuel ratio control mode.
Another special feature of the E-2 is that it drains fuel from the fuel manifold
The fitting connects to the fuel manifold
, which cracks easily if you're not careful.
Flow uniformity in this region is important for adequate cooling of the thrust chamber and for flow uniformity in the injector's fuel manifold
Investigation of the wreckage revealed water in the engine-driven fuel pump, mixture control inlet screen and fuel manifold
Air manifold pressure was the same, horsepower was the same, ignition timing was the same, fuel Btu was the same and fuel manifold
pressure was the same.
