A few posts ago someone said that a direct injection diesel ( eg 300 Tdi ) did'nt really need glo plugs as they started much more readily. Question is, more easily than what system and what actually is direct injection/ is it the same as common rail diesel etc.

As I understand it, indirect injection (like mine) injects into a swirl chamber above the combustion chamber. Direct injection... well, it's kinda more direct....

Direct injection starts easier than indirect injection...
Direct injection means that the injector fires straight into the cylinders rather than into a little mixing chamber next to the cylinders
Common rail diesels are direct injection put are injected by the 'tap' being opened on a fuel rail that is held at pressure rather than a sqirt of pressure going up each injector pipe in turn.... this is more like a petrol injection engine ( most not all )
Rather simplistic I know but roughly how they all work......
