I always assumed TDI stood for turbo diesel injection. Since all diesel engines are fuel injected, any of them with a turbo must be a tdi

This is where I get confuddled. If fuel is fed into a combustion chamber via an injector, it is injected. Im not sure when manufacturers started using the description tdi but my earliest memory of it was the vw golf.

Welcome to the Forum. I’m a Yank from Chicago on this forum but living in England.
Sorry, no corn dogs or grits this way. I only have steak and kidney pies and chips from East Anglia.

Exactly. Direct injection, the atomised fuel is injected into a combustion chamber.
Indirect injection, the atomised fuel is injected into a pre-combustion chamber, or swirl chamber.
The vapour swirls around in that chamber, also gaining some heat from this, and is then sucked into the cylinder, where it is compressed by the piston until it ignites.

Thanks for your explanation, I keep hearing about swirl chambers on here but didnt really know what they where. I just imagined they were part of the combustion chamber design that agitated the atomised fuel.

They are a separate chamber, connected to the cylinder by a small port, through which the mixture enters the cylinder.
A lot of people are confused by them. It doesn't help that there are several names for them. We always called them swirl chambers, but some manuals use the term pre-combustion chambers, and Land Rover used the term hotspots in their manuals.
