Is Compuvalve a bi-fuel issue only ?

[p71]

I have a 2003 Crown Victoria dedicated CNG that is misfiring after having filled up at the Burbank fuel depot (Clean Energy). I assuming that my injectors have been clogged with oil but want to rule out the "Compuvalve" issue, isn't this for bi-fuel cars only ?

I don't think so. I think there's one in every Ford with factory CNG.

Correct. The Compuvalve is used for delivery of CNG to the engine as opposed to petrol via the fuel injectors as most people know fuel injectors to be.

Thus, dedicated Ford's do not need a compuvalve.

Newer CNG engines use injectors. Older ones are like carbureted systems (except the fuel is already gaseous) which include problematic components like the Compuvalve (Ford) and the Gas Mass Flow Sensor (GM).

I think the point is that since the OP clearly described his car as a *dedicated* CNG that any problems that might be caused by a Compuvalve is a non-issue because dedicated Fords do not have a Compuvalve.

Thanks, one and all for the help with my question.
