Oh, but that's not what I'm referring to, High Pressure Fuel Injection assures that every molecule of hydrocarbon is properly surrounded by air for complete & much more powerful combustion, sort of like the dust explosions in the old grain elevators.

If one could climb down to Jimminy Crickets scale of molecular viewpoints, todays engines are lacklusterly tossing clumps of logs on the fire like wasteful locomotives in an old western.

We would still be breathing wasted combustion byproducts of these "loco ~ motives" just like China is today, were it not for the little heat engines called catalytic converters clinging to our tailpipes under our a$$$es.

But, that's another story of corruption and control I'm not at liberty to reveal.

It was my understanding that the high-pressure injection systems are designed for compression-ignition engines not spark-ignited ones like gasoline fired.
