Ford's Ecoboost V-6

[r0tor]

W/the additional pumping losses and weight you will never get the gas mileage of a normal 3.5

Part of the turbo theory is reclaiming energy in the exhaust gas and using it to reduce intake losses...

[SVT32V]

I mention that only in terms of fuel efficiency.  I expect that direct injection could be more appropriately metered than port injection and the engine could be made to run more efficiently.  As well, with direct injection and a smart computer process, you could start the engine without other than squirting a bit of fuel in the cylinder which is best situated and then firing it off.  Stopping the engine when the car is stopped and refiring it would be simplified.  I'm not too sure why there hasn't been more development of this feature.  I believe Mazda had experimented with something like this. 

More importantly with DI you can run more compression which does increase efficiency.

The way I see it, if you're out of boost you've got a normal N/A motor with big restrictions on both the intake/exhaust

And then once you're in boost, there's prob a sweet spot of increased efficiency up to a certain point, but from there on you have a 350HP engine.

Ford has built the first of a new breed of turbo engines designed to improve fuel efficiency. In the past, turbocharged engines have been used to boost power rather than save fuel. They ran at efficiency-killing low compression ratios and rich air/fuel ratios to prevent meltdowns. The 365-hp 3.5-liter EcoBoost V6 uses several tricks to overcome these limitations. For instance, the direct fuel-injection system squirts fuel into the combustion chamber instead of the intake ports?this cools the chamber, allowing for a fairly high 10.0:1 compression ratio. The new V6 debuted in the Lincoln MKT and MKS, and the Ford Taurus SHO.

That's bullshit.

1. They must not have heard of the BMW N54.
2. I don't buy the "eco" claim at all.

Yea, I was gonna say there's nothing economical about a 360+ HP engine in a passenger car. Ford needs to utilize Ecoboost on a small 4 banger, retaining the gas mileage of the 4 banger while gaining the performance & effortlessness of a big V6. When they do that, I'll be impressed by their boldness. However, manufacturers have been utilizing turbos for that purpose since.........

.......the first turbo Skyline from the 80s?

[GoCougs]

Popular Mechanics is one of the worst magazines in print. It's absolutely terrible. All that technology has been around for some time - and lolz at describing direct injection as if though it were brand new technology.

It's a good effort, especially for Ford, but really nothing ground breaking. Put the "Eco"boost into a $28k Fusion and now we're talking, but for $40k+ vehicles, 365 hp is nothing special.

I think that's really only true with a very big turbo.  With smaller snails there is very little restriction on the exhaust off-boost.  Even keeping my foot out of it my car is no slower than our Outback with the same size DOHC motor.

Those, '78 Buick Regal and LeSabre, '80 Turbo Trans Am... Lots of other stuff came out around then with a turbo.

It has a timing belt?

Not necessarily material, but still annoying.  Chains are the way to go.

Well I don't know the EJ20T intimately but I'd imagine that puppy starts spooling around 2K. Plus it prob has a relatively high compression ratio. My car has an 8.8:1 ratio w/no turbo, and it pulls nicely from 2K and beyond.

For a low power/boost/displacement application I think a turbo would beat out either a bigger motor or a higher revving one. Which I guess is the point. But the whole 'Ecoboost' moniker on a 360HP engine in a passenger car just seems goofy to me. The smaller applications are much more sensible.

It felt a lot faster than it really was. My brother had one until he blew the engine. Damn turbochargers...

A little odd .  It must be based on the Euro Zetec rather than the Mazda MZR.

[93JC]

Meh.

$10 says the 1.6 L Ecoboost engine is just the ol' 1.6 L Sigma engine (which uses a belt) with a turbo on it, and the 2.0 L Ecoboost is the 2.0 L MZR/Duratec (which uses a chain) with a turbo on it.

That works for me

And belts aren't that bad if it's a motor that's popular for rebuilding. One of my biggest fears of dealing with a Maxima engine build is getting the damn timing chain reassembly wrong. Belts are much more forgiving.

Two turbos with direction injection and whole lot of software modifications.

What the hell are you trying to say? 

[sportyaccordy]

What the hell are you trying to say?  

If you are looking to make a moderate amount of horsepower, to me a small, low pressure turbo motor would make more sense than a high revving naturally aspirated motor or a needlessly complex + heavier larger motor.

I.e., VAG's 2.0T to me makes more sense in 99% of the car they offer than their equally powerful V6, or something like the K20A in the Civic Si. The GTI has the best gas mileage for a ~3000#, 200HP car that I've seen in a while.

My issue is that they are calling it Ecoboost, when it is in no way eco-friendly or economical. But overall, turbocharging does make a lot of sense.
