This idea is similar in principal to turn of the 20th century diesels. They didn't have a way to create high enough fuel pressure to run true direct injection so they mixed the fuel with high pressure compressed air to deliver it to the combustion chamber. One thing that stands out to me is the reliance on electronic systems to enable such advances. One part of me looks at old technology like vacuum advance ignition timing and automatic transmission accumulators. Or even a WW1 era naval torpedo. While I realize and appreciate what computers can do, I think modern engineers take them for granted. Look what can be accomplished without computers. You can literally build a "computer" out of kinetic moving parts... so I'm not entirely sold on the notion that you need to wait for advanced enough computers to accomplish something. If you can define a physical output based on physical inputs in an algorithm and feed it to a computer you; have to be able to duplicate that algorithm purely mechanically also.
