ALL diesels are direct injection - it's now being implemented on gas engines as well.
I know diesel pressures have been high but I don't know the difference in the current diesel injections systems from the past other than some are using direct injection via individual injectors for each cylinder rather than a common rail. Actually high pressure injection began with gas motors in the early 1900s. Just a little bit different now.
