Posted for Walter Atkinson <walter@advancedpilot.com>:

  The first direct injection aircraft engine of which I am aware was on the
B-29.   That was 1945.
  
  It's not a new concept.  Being able to make it work properly and being cost
effective may be a new development. <g>  Here's hoping.
  
  So far, there have been several attempts at this.  While they have worked,
none has proven worth the extra expense and complexity in aircraft engines.
  They can be a maintenance nightmare.  (ask the guys who work on FiFi.  IIRC,
they've switched them back to carbureted engines.)
