GDI In Your IHC

https://en.m.wikipedia.org/wiki/Gasolin ... _injection

Took a second class on computerized Gasoline Direct Injection tonight. There will come a day in the near future when everything automotive gasoline-powered will be GDI.
It has incredible improvements over non-GDI.
Up to 50% higher low-end torque. Improved exhaust emissions due to atomization and precision of direct-injection. And of course, better fuel mileage.
Add a factory turbo and expect 300 or more horsepower from a tiny down-sized 2.0L "everyday groocery-getter".
Incredible!
That's in a light-weight package, BTW.
These things will rule the boulevard!
Who will be the first to transplant one into a IHC? I'd like to try! It will surely fit.

He said, ", but it's a daunting task."

Ohhh just wait...

When it is something that excites, those Daunting Tasks become unique challenges.

It is all doable.

A diesel (either direct or in direct injected) will run just fine on gasoline, but gas lacks the necessary lube quality of diesel so the pumps and injectors suffer an early death. What are they doing on these new direct injected gasoline engines to lube the high pressure parts? I am reading that they have done it, I just don't understand how they overcame the lube problem. If not for that, we would have had direct injected gas years ago.

CB, evidently the Germans had mechanical GDI in airplanes during WW II. At least that's what the class taught us.
No mention of a "lube problem" as far as fuel.
Injectors are either a relatively high voltage solenoid (50v) injectors or up to 200v piezo injectors. The piezo type uses tall stacks of crystaline material that's subjected to the higher voltages as mentioned. The piezo material expands just enough to open pintle, but requires a similar voltage "signal" to close it! Weird! Never heard of such a thing.
Fuel is pressurized the common way via a in-tank pump to about 50psi and then a cam-driven high-pressure pump raises pressure to 3000 psi max.
Quite the deal!

wonder how well it worked of old if we are just now getting back to it? I know we had "pressure carb's" back then for aircraft (precursor to fuel injection). I just don't understand how you can pressurize to that pressure without some sort of lube to the pump element. Diesel can provide enough so the element will not seize in the barrel, as it is an oil, but gasoline is a solvent and strips any lube.

CB, these GDI engines can have up to 15:1 compression and be as lean as 65:1.
Back to 3000 mile oil change intervals (at least the turbo versions) and synthetic oil, only.
One crazy drawback is that there's no fuel to clean off backs of intake valves so they have a tendency to get packed with carbon to the point the port closes off.
Just such a strange and wonderful design!

I know one 6.9l in a Ford that had 15 gal of gas run thru it and lived, and they have around 20:1 CR.
