Direct Injection 3.7?

Thought this was an interesting read. Old article, but the engine is still the same...

You guys think that today's tech would make it more beneficial for our engine to have DI? Or maybe the article is just trying to cover up cutting off costs?

And this says nothing about carbon buildup, which is the main thing that worries me about direct injection. It looks like they are starting to figure out a solution with the dual injection systems, but we need to see what the insides of those engines look like at 30k, 60k, etc to make sure it works like it is supposed to.

I think it's because the fuel saving is not worth the extra cost.
Can you imagine having a high compression V6 or V8?

I like to having the intake valves cleaned by the detergent that I paid for in the fill up. One of the reasons with going for the V6. I have owned DI cars. Sometimes simple things are better.

actually our motors are a fairly high 10.5:1 compression ratio..back in the 90s that was about unheard of on a production car. everything was 9.5 or under. the fact we can run 10.5:1 on 87 oct is pretty awesome, especially considering how much power we can get from a little 227 cu in motor....I mean, consider that will you! 227 cubes....making more power than any hot dog 289 did back in the day, with 2x the fuel economy.....and less weight. yes....I love technology still, something to be said for the simplicity of old carb'd motors

Carbs and simplicity is an oxymoron. Everyone knows carbs are built upon a combination of voodoo magic and unobtainium.

Seriously though, I'd take OBD0 or OBD1 level fuel injection over carbs for simplicity any day of the week. I agree we're getting back to being too complicated now though.

For my new truck I steered clear of the DI as I just don't trust it long term. Now the newly redesigned 2017 3.5 Ecoboost with the dual injections should be better.

Look at the 3.5 V6 twin turbo in the 2016 Ford GT, racing in ISMA 630 HP / 530 TQ.

Dual fuel injection (PFI and DI) is the future. The only thing that gets worse is engine complexity. All other attributes are improved (fuel economy, power, response), with the exception of high pressure pump noise if not compensated for well.

 

[davejonnes]

Yeah, I see the idea here. DI or PFI will end up having an upper hand in terms of performance/economy. But at the time Ford was developing the 3.7, the cost was not worth it to them I'm guessing... or the technology was still fairly "new", not as matured.
