+1.
In the highly polarized world of politicking that occurs in the USA today, everyone is looking for something to be enraged about,msomething to blame someone else about, etc.
End of the day, DI isn't new, it's not evil, heck, it isn't that advanced. It's essentially how diesels have been making power for decades.
One really has to look at it in a reasonable middle ground without going in looking to get panties in a bunch.
There are very efficient, very clean operating, high mpg non-di engines
There are very inefficient, high polluting, low MPG di engines
If people would learn something besides how to polarize and argue, they might understand the thermodynamic benefits of DI.
It's a developing technology for sure. But then again if traditional FI was so great we wouldn't have a fuel additives section where fi cleaner sells like wildfire and people worry about maintenance doses for their engines.
Instead of looking at how to blame the EPA for di, why not get out second year engineering textbooks and try to learn why one might want it in the long run.
Good points. I was a LITTLE bit nervous about buying the Impala with DI, but after doing some research on various forums, it doesn't seem to be a problem for GM. I am willing to "risk it" for the benefits - that is a decent amount of power with pretty good MPG.
