it's not for sale...it will be used as a dummy vehicle for my port fuel injection x-flow project.

My grandpa used to own it so it's more than just metal on wheels.

Sorry

[pintopowerwheels]

yes it does! they do some strange conversions over there still cool though

@noe179

the stoichiometric ratio assumes that no fuel falls out of the charge, if it does u need a richer mixture for the right mixture to be ignited as some just passes through engine and makes big HC emmissions, u therefore cannot run a cat on a crossflow; a modern engine uses swirl so mixture remains suspended/ atomised; a crossflow has non.

ever had a modern car with a missfire and killed the cat?

modern emisions stuff just ruines cars, putting it on an old engine is pointless.

If you run an engine lean, it simply cannot be clean - the NOx levels with shoot way up. The point of having a 3-way catalyst with a downstream oxygen sensor is to calibrate the engine around stoichiometry. The sensor output should be quasi-steady around 620mV. If it switches similar to an upstream oxygen/lambda sensor, it means that the catalyst is fouled or dead! They also do it on newer vehicles equiped with OBDII in the US and newer EOBD compliant vehicles in Europe. Cheers

@noe179

ok I'll re phrase that!

by the time u get a crossflow any where near clean it will have no power and probably have to be so lean that it glows!!! (joke).

its a bit like polishing a turd.

[noe179]

You're telling me not to try? I'm laughing at the moment.

Sure I will try and if I fail, no big deal! It will be a bigger failure if I don't try!

cheers

@noe179

dont try and make crossflows exhaust emissions clean u will fail!

crossflows always have high HC emissions due to lack of swirl in intake/combustion space.

this lack of swirl causes fuel to fall out of charge faster so u have to run rich to compensate- a lot of fuel doesnt even burn it just puddles through!for this reason a catalyst is out of the question.

exhaust cats cause more pollution if u do short journeys on normal cars also!

Well, I'm an Engineer of some sort and enjoy anything doing controls, mechanical and some electrical stuff. I'm no expert in anything but lately I have built my own water brake dynamometer. (watch it in my channel)

Currently I'm rebuilding a 1.3 x-flow (681F type) for this escort but the plans are fuel inject this engine with better controls and maybe even a three way catalyst. Sorry for the technical jargon. and thanks for your comments

@noe179

what do u mean dummy vehicle?

u gonna strip it and test fit parts? why not use actual project car for that?!

also 33mpg? a petrol crossflow could do that!

[johnzejtun1993]

Have you sold it ?

I absolutely love the old Mk I's.
