Direct Injection

[ryeman]

....forgot to mention, that DI V6 exported by Holden is the basis for the Alpha Romeo FWD and the Opel equivalent ...so FWD Commodore anyone?

The rest....where to start....a graph of comparative sale figures...a graph of local investment in in technology ....fuel figures are equally comparative, you can't cherry-pick the results.
The fact that we love our out-of-fashion RWD Falcons in all their guises, is of zero consequences to Detroit management.
Realistically the KUGA (FWD)and hopefully the Terri (RWD) as well(?) are the future because that IS the future combined with Fusion/Focus/Fiesta.....you don't have to be a genius to see what staring you in the face...BTW Kuga 0-60 in 5sec!!

what the hell is that crap?
their are three types of imperial, when converted to metric they equall the same.
38 us mpg is the same as 45 uk mpg when converted l/100..

you should be in marketing, erroneous at best.

Toyota have solved that issue by having both DI and port injection on the same engine. (various Lexus' and the 86)

Its also got nothing to do with fuel quality.

This man knows what he is talking about. I've owned a turbo Mazda for five years and seen my share of issues on the forums. My wife still owns one. Carbon build up and sludging valves are not uncommon.

Yeah, why worry about unfortunate facts, I only ever read crap I guess...pretty depressing really .....

I somewhat agree..
It's not just how lean they run, the burn is more efficient and emissions are less.
Yes they are designed to be more efficient and they are to some degree..
In terms of the fuel it's all in the ecu logic, there have been cases of mazdaspeed or mps's blowing rods out the block due to lean conditions. But that seems to be a code issue in the ecu. It's happened here and in the USA.

The cars are tuned differently for us here but the benefits are comparable. I'm not a fan but that's where they are all going to go.

Lets address an important issue first, why is our fuel so crap? Is it because its cheap?

When I was at Honda, we had issues with the new Jap built detuned Accord Euro for our market, with fuel quality issues even on cars which had been running premium fuel.

[ratter]

the Stratified Injection is only meant to happen under light load conditions, i.e not under heavy acceleration etc, many cars overseas use it with out problems but the extra exhaust components do not handle the fuel here so it is not widely used here, I suggest mazda had a programming issue causing ping if rods were exiting blocks

If I remember correctly, it is the sulphur level of the fuel over here, it will kill the nox sensor, again if I remember correctly the next emission level will also have a minimum standard that fuel has to meet so that means our local refineries will have to rectify this problem

The EcoLpi Falcon as result of he ~110RON equivalent has a cr of 12-1.
FWD or not, that's the competition so to compete can we expect the 2014 Falcon to at least keep up?......unfortunately Ford Detroit sees its future profits coming from the F150-250-350-450 with a little bit of help from the FWD Fusion n Focus. :-/

I still will not buy the mazda.

The current Falcon is a safer family car and petrol is the cheapest part of running a car.

Nothing else matters except outcomes after a collision.

And that's the reason they are closing down the refineries .... Euro vi can't be produces without a massive spend....maybe Singapore refined 91 (shipped thru Darwin?) will be of higher quality and, along with diesel, lower sulphur content.
The Feds must be worried about the Defence implications.
Ahh, I've just worked it out the Commonwealth Oil Refinery (COR)...

Yes. But some people don't know that a US gal is less than a Oz/UK gal.
And will convert US mpg using the wrong convertion of 4.45L/gal to get the L/100km.
I think that is what Ryeman was on about.

true thats why i said he should be in marketing..
FRED: i get 38mpg
BILL: i get 48mpg..

same crap, just missleading.

hence the metric system, all the same in every country who uses it.

Im not sure if there is.
Its only Japan that gets the ultra high CR Skyactivs. US (biggest market) and here get the lower spec ones.

Perhaps Japan just has better fuel than everywhere else, but that doesnt automatically mean we have crap fuel.

Though even in the AUDM Honda Accord Euro's were coming back in for lots of warranty work to do with bad quality fuel, even 98 was causing problems. That was in 2010, in a detuned car for our market.

Again maybe Japan has better fuel than everyone, who knows? Why would they have good fuel though?

Take a look at just about all the Honda's released here in Australia, most of them have all been detuned to run on our crap fuel, particularily the Type R models.

Same thing with our diesel quality up until a few years ago, probably the reason why we didn't see turbo diesel small cars come here until the same time the fuel quality changed.

[XR Martin]

But even CRVs were having pinging issues, so I suspect it had more to do with ECU tuning, rather than fuel. Plenty of other makes and models never have a fuel issue here.

[ryeman]

All engineers employed by the manufacturers either local or fully imported know exactly what the local fuel standards are wherever they sell, if they didn't they wouldn't have a job.

I don't know about that. We still have a handful of local refineries. I don't think necessarily detuned for fuel. More plausible for the climate..

Lots of people readily say that the USA has better fuel than us, better in which way? Maybe fresher in some circumstances. Though I don't see how it can be any more than the locally brewed, read - not imported. I think some of the confusion is around how different countries measure fuel quality or octane ratings - USDM is MON. AUDM is RON.

Low turnover outlets ?
Stories of contamination - watering down ??? Maybe it's risky out there.
