Direct injection on the Ecoboost

[FreightTrain]

I haven't looked into it to much but is ford using an injector pump like a diesel in this set up. If thats the case is this going to be the weak link on these motors. Anyone have any idea how much it's going to cost to fix the direct injection when it takes a shit on you down the road. I'm considering a new truck and just weighing the options between the ecoboost and the 5.0.

does it matter how much it costs? you just got paid more for work you already did and all.

modern diesels use a fuel rail and electronically actuated injectors...

if they survive fairly well at 20-30,000psi, the direct gas setups at 5-7k psi should be a cake walk

Thanks Cooter,

In your opinion what do you think will be the weak point of these small V6s with twin turbos. Is heat going to be the death of the turbos.

did you see the torture test video of the EcoBoost?

I wouldn't really worry about it

Damn just watch the video and it's pretty impressive. Here is the link if anyone else hasn't seen it.

I wouldn't wory about the turbos putting put too much heat, they are the size of large snail. Two of them are maybe the size of one 12 oz Dr.Pepper can. At least the ones that were on the cutaway engine at the Dallas Autoshow were very small.

smaller turbos make more heat... more restriction, less efficient compressors, etc.

The limiting factor to direct injection is that nobody makes upgraded pumps yet when you really want to crank things up. There is a limit to how much fuel they will flow and once you hit that, there is no extra available.

nobody makes upgraded pumps for a 2yr old economy engine? not surprising...

somebody will... on the Bosch CR diesels, we have upgraded pumps or dual pumps. it'll happen for the ecoboost stuff before too long IMO

There are upgraded aftermarket pumps out there for VW's and the Mazdaspeed cars. In both cases around 350-400hp seems to be the limit for the stock pump. The thing that seems to be giving the most trouble on di gas engines is the amount of build up on the intake valves.

due to lack of fuel running across them?

I have like ZERO 1st had experience with DI Gas

Yes, by not having the valves washed by fuel flowing across them, Ford has addressed this problem by tweaking the timing via the TiVCT on the intake side of the cams.

Diesels have been doing fine for years, but the combustion byproducts are obviously different between the two
