Direct injection of gasoline was invented here, but no takers from
'our' OEMs...the Japanese (Isuzu) licensed it first and had a truck
V6 in the late 90's. Early 2000's had Toyota offer it here, but the
injectors were not capable, yet. So supplemented by port inject at
the higher throttle settings.
Over time in a very competitive market...they will all have very similar offerings
Power, MPG, comfort, ratings, etc
They will all have a host of problems during their teething periods. Some more
than others and will reap the benefits (loyalty, market share, awe factor, etc)
That also depends on how management plays marketing...GM had direction injection
gasoline ICE's years before Ford, but upper management decided such a wonderful and
powerful thing...that they dictated only for their lux badge...Caddy. Ford
beat them to the truck market and the ECOBOOST reins top dog for now
This GM V8 6.2L's spec sheet looks just like Ford's V6 EcoBoost...but GM decided to
keep the displacement to a larger V8 and get the MPG with cylinder deactivation.
Ford chose a smallish V6 with forced feeding
Turtle mentions that, that V6 is forced fed air similar to a big block gasser
of yesteryear
Laugh, because folks don't know what he is saying and double laugh as think he
gets the similar headache I get on similar techie discussions... :B
Current whizbang is direct injection, cylinder de-activation, variable cam timing,
very good materials/production science, etc
Next gen will be GDICI (gasoline, direct injection, compression
ignition...no spark plug). This may greatly reduce diesel in 'cars'
and light duty trucks...NOx will still be the bugger, as these will
have very high combustion chamber temps
As usual, the racers will have this first. Not just track anymore, but
street racers...pony cars...muscle cars...exotics/super cars...
