How are the "injectors" attached to the engine? Are there "metered pills" attached to ports in the heads or the intake manifold?

This is not a timed injection system? They are shooting all of the time?

How is the fuel timed?

This is timed . I will get you some photos today of injectors and intakes.

There is a electrical trigger attached to the ignition system that fires the injectors.

I appreciate that Ed, sightings have been rare in recent years. The Coralsnake has a masters degree in social distancing.

Unfortunately, I had to decline the invitation.

But, I am planning to attend the Indiana event.

Here is a picture of the injectors on the Green Hornet XE intake. They are bent so the head goes into the top of the combustion chamber. The manifold holes are tapered and each injector is a press fit.

When the ignition trigger is activated, all eight injectors fire.

Pete,

Thanks for all you have done to get 101 ready for this auction.  I share your excitement and hope she lands with someone who truly values her.

Interesting system. Do you know the trigger frequency on 720 degrees of crank rotation. Wondering how they managed to get a evenly distributed A/F mixture on all 8 cylinders.

I could see with that set up that during a injection cycle a few cylinders would be on a optimal amount of fuel atomization while others would be slightly timed too early and others too late. Hang time in the intake runners waiting for the intake valve to open the possible drawback. Some more modern systems used to alternate 2 cylinders at a time on 4 cly engines.  Very forward thinking at the time and I suspect  less problematic system than the Rochester units that preceded it. Would be cool to see it running and maybe put a temp gun on the exhaust runners to see how even they are.

And more photos on their website

Sorry for the delay on the fuel delivery system. From memory its triggered by a sensor on the number 1 plug wire. I couldnt find the exact rate but it is calibrated to engine speed and measured in milliseconds. The specific curve is programmed into the computer and there is a heat sensor, but this is pre-oxygen sensor. There is a barometric sensor that also gives input.

The potentiometer cards were a challenge as there are very places that could reproduce these. Luckily, the company I actually found to make them was only an hour away from my house and I needed special clearance to even visit them, because of their classified government work.

Thank you for the US military.
