I assume the atomised fuel hangs in the pot and is compressed without spark on the first stroke, then injected again on the second stroke and compressed with spark...

But, rather a lot of my guesswork is supposition... this has actually really thrown my ample knowledge of the I.C.E. into disarray...

It loiters in the inlet port since it's an indirect injection engine..
There are modern direct injection petrols, but not this!

I wasn't aware that the injectors fired twice over 4 strokes though, this is news to me, and doesn't seem to tally with the way my car injects...

Is yours 4.1?

erm... it's a 2 row ECU... if that makes it a 4.1 then yes, and 4.1 does ring a bell..
