TDi90:
hence TDi90 8)
muddysteve:
"Di" - direct injection
i've had other motors with turbo diesels and intercoolers but all the indirect injection have been TD's or Turbo Diesel's and all the direct injections have been tdi's
Range Rover Blues:
He's right, Di is used for direct injection, it's one of the ways of making oil burners drive more like real cars ie 'high speed' engines. Di engines don't have the restiction inherant in indirect injection at higher speed namely the throttling effect of the pre-combusion chamber inlet.
The downside is slightly higher fuel consumption and the rattly noise we all know and love, because the combustion is happening in the top face of the piston which is effectively loose in the bore, rather than inside the pre-combusion chamber like on a Recardo head for example.
