What is Earthdreams Direct Injection?
Sorry if this is covered in other places but I was curious why people talk about it.
What exactly is Earthdreams Direct Injection - is it something like turbo?
What cars is it in currently?
In what ways does it make your life better?

http://en.wikipedia.org/wiki/Internal_combustion_engine, Gasoline Direct Injection (GDI), also known as Petrol Direct Injection or Direct Petrol Injection or Spark Ignited Direct Injection (SIDI) or Fuel Stratified Injection (FSI), is a variant of http://en.wikipedia.org/wiki/Fuel_injection employed in modern http://en.wikipedia.org/wiki/Two-stroke_engine and http://en.wikipedia.org/wiki/Four-stroke_engine http://en.wikipedia.org/wiki/Petrol_engine. The http://en.wikipedia.org/wiki/Gasoline is highly pressurized, and injected via a http://en.wikipedia.org/wiki/Common_rail fuel line directly into the http://en.wikipedia.org/wiki/Combustion_chamber of each http://en.wikipedia.org/wiki/Cylinder_%28engine%29, as opposed to conventional http://en.wikipedia.org/wiki/Multi_Point_Injection that happens in the http://en.wikipedia.org/wiki/Inlet_manifold, or cylinder port.

internal combustion engines, Gasoline Direct Injection (GDI), also known as Petrol Direct Injection or Direct Petrol Injection or Spark Ignited Direct Injection (SIDI) or Fuel Stratified Injection (FSI), is a variant of fuel injection employed in modern two-stroke and four-stroke gasoline engines. The gasoline is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port.

Also, there are a few potential downsides to DI, which include unknown very long-term durability because it is a new-ish technology and some people are experiencing carbon build-up on engine internals with some DI motors. Nothing conclusive or serious to worry about at the moment, but good to know about.

Earthdreams,
Skyactiv,
BlueTec,
Etc.
These are simply marketing words designed to convince the consumer that car companies are working with advanced technology. In fact, the internal combustion engine has changed very little in the last 100 years. Today's engines are pretty much all the same.

so, they are not the same.
Direct injection IMPROVES power and Economy, but as CGTSX pointed out, it can have some drawbacks.

Earth Dreams is a catchall for a suite of technologies that, as noted, improve power and fuel economy. Yes, it is marketing. Curiously, we complain about Honda marketing and when they bother to do it, we complain about Honda marketing. LOL.

Did your google develop an echo?

Nope.
why would it be? the injectors are spraying directly into the combustion chamber forming carbon buildup in the intake valves.
one way to solve it, is to add an oil/air separator, aka, oil catch can.
No manufacture will add an oil/air separator from factory because of cost, and its one more thing that the consumer has to empty/take care of, ie: warranty

Honda is so late to the game with Direct Injection technology, and I really thought Honda must have done something special to the EarthDream engines to warranty such a late entry.

The carbon build-up is usually broken up around 60K miles with a walnut blast. Price varies but like anything it will continue to come down as more people buy the equipment.
Best factory solution so far, don't remember who has it, is a secondary injection of fuel into intake runners.

The IS250 doesn't have it and that's why it's suffering the CB problem which Lexus has addressed with a silent recall. The procedure is considered a major repair though.

Not sure how major it is, a lot of 135/335 guys are DIY'ing the walnut blasting process with great results.

Except, as usual, they've done it better than others who were not so "late to the game." Compare the acceleration and mpg figures for the 13 4 cyl. Accord versus Sonata, for example, and I mean in the real world, not Hyundai's made-up, marketing fantasy land. Our 2.4 MT easily hits 40 mpg on the highway. C&D tested the same car (EX, MT) out at 6.6 in 0-60. I'd call that pretty special.

This doesn't solve the inherent major "drawback" of DI (in quotes because it is also what gives it its greater power density), which is what actually forms the carbon - the significantly increased cylinder temperatures which will naturally lead to oil coking on the piston and intake valve.
