Thank you everyone!
I think - the confusion / issue is probably stemming from the training I received when I did my differences training (some time ago now...)
I was definitely handed a sheet outlining engine function which in fact is jet-prop and not a turbo similar to the turbo in a car! How strange! I was explained the basics of a jet-prop instead of a standard turbo, then plonked me into a PA28RT and given different start instructions (different from carbureted and from fuel injection engines I had flown) so I just assumed (to this day) that this was how the engine ran!
How naive is that!?! I blame my training...
Although looking back if that's the only difference, why require differences training at all!
Thank you for helping me understand my idiocy! (without killing me!)
Actually thinking of it now... There were no mention of engine cycles, there was however mention of hot starts and other elements that also allude to the instructor teaching turbine rather than turbo...
