I love how people become experts after reading a few articles on the internet when they have no real world experience at all.

 

I love how people that have no idea what they're talking about like to chime in and add no worthwhile information. Thanks for the post I'm just using the most credible information I can find. What's wrong with that? Do you have a better source than Joe Mondello you'd like to use/quote to argue against me with? Yeah...didn't think so. Do we really need to continue this discussion considering the results from the GMHTP head shootout?

 

If I'm not mistaken that's the next step in technolgy for fuel injection, to do direct injection into the cylinder. I think they are able to get better fuel atomization for they run higher fuel pressure and the injector is able benefit from that when doing direct cylinder injection. They are able to reduce the emissions of the engine and also increase fuel efficency and increase high power output as well.

I've also read about how they are also able to get rid of pumping losses by not using any throttle plates and using the fuel and injection timings to adjust to varying load conditions. No expert on this, just some things I've read about it is all.

 

There's actually cars on the street now that are direct injection.

That pretty much proves my point too. Thanks for bringing that up.

If the injector is doing it's job, then atomization is taken care of. If a injector wasn't completely and optimally doing it's job, then I doubt direct injection would be beneficial/possible. According to some of you, the fuel would still need to be further atomized by the rough surface of the cylinder wall. That simply isn't the case and direct injection proves it.
