    Direct injection for Cruze 1.4 - 2012?

    Hey, anybody know when they are going to put direct injection in the Cruze 1.4?

    Seems like a no brainer, I don't know why it isn't already DI.


    thanks

    As posted several other times on several other vehicles (notably the newest versions of Ford Taurus and BMW), the kinks aren't worked out of DI just yet. There are (in some cases) severe problems with carbon buildup that some manufacturers are blaming on fuel, and others are taking care of under warranty.

    Until those kinks are worked out, I say you can keep your DI. No thank you.

    When we talked to some power train guys in Detroit last year, they said they could achieve the 40mpg without going to DI on the 1.4t, but it could be implemented pretty quickly.

    Also DI fuel systems are expensive. I think that in 10 years or less, when everyone is replacing fuel pumps, that four figure number is gunna hit them hard.

    There's always that... But it sure works well on the Equinox and Redline Injector Cleaner seems to work well in keeping things clean.

    I thougt the Cruze would get DI when GM switched to its next generation of sub 2 liter 4 cyclinder engines. Because the one presently in use by the Cruze is a little old.
    "At what point then is the approach of danger to be expected? I answer, if it ever reach us, it must spring up amongst us. It cannot come from abroad. If destruction be our lot, we must ourselves be its author and finisher. As a nation of freemen, we must live through all time, or die by suicide."

    Someone will have to refresh my memory-the videos I have seen posted on a couple of non GM's show that the cleaners are not getting the carbon out. Not even with they tools to flush the system the cleaner manufacturer's are providing to shops. One manufacturer is even removing the heads periodically to do the job correctly.

    Only a matter of time until the bean counters get a hold of that one and say "no way is warranty paying for this any more".

    Doesn't sound like all the bugs are worked out of DI to me. Either that, or we need a higher quality fuel than is currently available. Which will mean more per gallon/liter. I still pass.

    Would you minds listing any of the models with the mentioned problem.

    Any injector cleaner run through the tank does nothing to help DI engines. It's the intake valves getting carboned up because fuel spray no longer hits the outside of the valve because the injector is now inside the cylinder.

    I ran a can of seafoam through my intake manifold at about 15,000kms. Through the intake is the only way to get anything on the intake valve.

    Google search shows Audi/VW coming up most often, but I don't see any manufacturer with DI engines not coming up at all.

    Yea, until every last problem is worked out of Direct-Injection, it ain't moving any farther.

    Why would there be a build-up of carbon on the intake valve of a DI engine? Air would be passing the valve, but not fuel.
    Are you saying carbon build-up on the exhaust valve?
    After combustion, why would there be a build-up on the more-precisely- burned-fuel exhaust valve?

    The air passing the intake valves also contains oil vapours from the crankcase. In the case of turbo cars, the pressure the turbo adds tends to push more oil into the PCV system and then onto the intake manifold.

    I installed an aftermarket catch can on my SS to try and limit the amount of oil going into the manifold. I haven't even had drain mine for the first time yet.

    Care to elaborate on that 2nd sentence Big Al? What I read into that is the fuel pump (I'm assuming the high pressure one?) for a DI engine is expensive. One fellow that had a HP fuel pump fail that was discussed on the tech forum said it was around $600 to replace. Not cheap but not a 4 figure repair either.

    There was a comment from a Ford powertrain engineer about this issue (I forgot where I read it; either Edumnds or Autoblog perhaps), where they claim they've got the issue under control in the Focus DI engine.

    I've not heard of the same carbon build up issues in the GM V6 DI engines. At least I've not read of any wide-spread issues so far. Can't say yet whether the 2.4L DI engine in my wife's Equinox will have the problem over time.
