Hello listers,



I was wondering, can a carburated Lycoming O-360-A4M 180 HP Penn Yan

conversion be converted to fuel injected?

I understand most cylinders have bosses for fuel injectors (plugged on the

carbureted models). Not sure if our engine has such bosses and how to check.

Thanks for any pointers.

Rumen,

Yes, you should be able to convert the -A4M to Fuel Injection. Look at a cylinder around the intake port. You should see two plugs there. The upper plug is where you would put in the Fuel Injector for that cylinder.

Perhaps one or more of your cylinders may have a primer nozzle installed in the lower port of any given cylinder?

Good Luck,

Konrad

Thanks, Konrad.

I am told there are no such STC's on file (so we could look up what

components are needed), so how do we assemble a list of needed components

(besides the injectors)?

STC???   It is for an experimental aircraft, or is it not? If not then I do not have an answer for you. But if it is for an experimental, then you may contact Airflow Performance for their fine system (...or any of the major engine builders for their opinion on what parts are necessary to make it happen).



Good Luck,

Konrad

No, Konrad, unfortunately it is being considered for a production aircraft.

That means field approval (if it can be done). But first we need to find

out how big of a project it might become, then the approval will be

addressed. At the end it might not materialize at all.

Best

Contact your local FSDO and talk to them about your intentions.  I think 

they will say you have to go through the ACO engineering and apply for an 

STC.  It is highly unlikely they would do a field approval from a FSDO.

Actually, LyCon has taken one model and converted it to another during

overhaul.   You still have the original tag, but, the paperwork shows what's been

done.
