GDICI is also in the works and beyond the proof of concept stages
Another potential is vaporizing the gasoline just before DI, but the pressures
involved 'almost' phase changes it back into a liquid...that is where tons of
patents *WILL* be
My bet is in pre-chambers. Either or for both liquid gasoline and vaporized gas
Current prototypes of GDICI has exhaust particulates and NOx in the same realm
of diesel
Think this poster meant GDCI not GDICI, nice idea, but like GMs HCCI cold weather/temperature will most likely send it back to the drawing board.
Currently, the Fed's have grants for sewage treatment plants in the Continental USA
for flare off gases to be converted into LNG for automotive use. I'm not a fan
of that, yet. My work in solid state compressors beats all of the piston compressors
both in efficiency and longevity. My city's PW's has an approx $2.5M grant just
for that, but am skeptical of how many gallons per day, vs the city fleet and
the ROI of such a venture
for a moment thought you were talking stereo equipment... we went from talking Direct Injection to Music... but then figured you were talking about FRICK Screw Compressors and their patented "Solid State Compressor - control system" (patented in 1978). Screw compressors used in the oil/gas industry are used as "booster compressors" pulling field pressure down to close to a vacuum and supplying a higher suction pressure for reciprocating gas compressors. Depending on how sets up are done, screw compressor can be very efficient or be power hogs. Hardly a "new" development as screw compressors have been used for years. As for Frick's Solid State Compressor - control systems, there are much cheaper systems that can be programmed to suit any end users process.
