Yes, but the text searchable database only goes back to 1971. These Bosch 
patents are al before then. Bosch apparently licensed some ofthe 
technology for the D Jet from Bendix. Bendix started development in the 
50's on electronic injection. Some of the patents show vacuum tubes!

Also, trademarks such as "D-Jetronic" are not found in the patents 
themselves, so you can't search by that term. Further, many patents by 
big compnies never make it to market because of either cost or reliablity 
or something else. So, I had to go through the old patents by hand to 
look for the ones assigned to Bosch, and then I had to determine if it 
was likely to be part of the D Jet system. O yeah, that's another thing. 
Systems liek the D Jet get patented in small pieces. You'll never so the 
whole thing in one patent. The more I searched, the more interesting it 
got. I certainly learned a bunch from reading them.
