Compuvalve Cleaning Patent

[Adrian]

Interesting reading on Compuvalve cleaning I came across while trying to research what I can do other than wait until Ford decides to make Compuvalves available again. This patent has a lot of good information about the compuvalve in general. It is likely a difficult to enforce patent against any private users, though surely enforceable against an institutional user. I wonder if this is why Ford won't clean these valves. Too cheap to buy the patent perhaps? Easier to just replace a $3,000 part? Who knows? Maybe trying to apply logic to Ford's thinking is illogical in itself. See attached pdf file.

Nice find. I bet one could rig up some adapters to a standard (gasoline) injector flush kit, fill it with alcohol and use a power probe to pulse the injectors. Someone try it and tell me if it works.

Where do you get this kind of data - is it readily available on the Internet? If so I've been underestimating humanity chances to survive.

Yes, you just have to search for patents. I checked to see what patents were out there related to compuvalves knowing I had a problem with mine and came across this one. Try www.patentstorm.com or the US patent office website directly www.uspto.gov .

you can clean the compuvalve and injectors by filling the cng filter cup with injector flush and running the engine.

At this time, my F-150 does not run on CNG due to the faulty Compuvalve, so cleaning it offline is the other option.
