So is the 2.3 NA motor non DISI?

[Young Roids]

Then I'll smoke you with my port injected 2.3 without its valve gunk buildup. Wasn't there a direct injected motor out there that still has 1 efi injector just to clean all the valves?

Thats bulls***. I ain't gonna run no injectors on my 2.3 to clean the valves.

 

[Young Roids]

its the same principle in basis, its not the same technology. and diesel is a poor example because it never caught on en masse. remember methanol powered cars and filling stations? yeah, neither do i. the success of direct injection will be pass/fail based on what mazda chooses to do from here with it. they have a four cylinder that makes 260 crank horsepower with 15psi of boost. tell me whats so special about that, honestly, that other manufacturers haven't met or exceeded now or on past vehicles. i can name several without so much as an effort or thought.



i'm sorry, you really aren't justifying your argument.

at present, i can think of innumerable reasons why i wouldn't take a DI over FI engine on this price category;

- fuel economy is no better
- air/fuel mixture is no better tuned. take a look at your tailpipe.
- power per liter is arguably worse than, or at the very best no better than, comparably tuned port injection cars with similar purposes
- parts are going to be cheaper outside of warranty
- vehicle will be easier to work on outside of warranty

if you like it and like the technology, thats cool. it has potential. but it is in its practically applied infancy and in practice has yet to prove itself vastly or remotely superior to port injection. the numbers and real world results bear that out. it has a ways to go, so based on all of that it doesn't "make no sense" for them to drop everything they presently produce and apply it to everything else. i'm not dogging the system, but its not the answer in its present form to a problem that honestly doesn't really exist.

I am talking about diesel trucks. They have been using very similar technology to disi for at least ten years now.

15 psi of boost is pretty good. Most cars run less than that. I am not gonna buy your lower boost pressure = better argument if that's what your making.

The market is gonna go that way. In ten years from now you can bet all the gas cars will be direct injection.

I think the overall design of the 2.3 liter disi beats any other four cylinder on the market. There is nothing out there right now that I like better in a four cylinder.

Fuel economy is slightly better.

The air fuel mixture is evaporated better tunning has nothing to do with that so much. Tailpipes get dirty, it's what they do.


Parts are gonna be a wash. I don't really think the efi injectors are that much cheaper. It's all gonna be expensive really.

And it's not really any easier to work on an efi engine than a disi. People said the same s*** about carberators.

Captain...just leave this guy be, in his other thread he said the ms3 is the best car on the road today and I tried explaining to him how the ms6/ms3/cx7 is Mazda's first shot at disi, so it'll take time for them to develop and perfect. 263bhp on 15 pounds in a 2.3L engine isn't really anything to drool about...but if he really loves his disi that much, then whatever, be my guest.

Oh...young roids...btw do you even work on cars?

**EDIT** Just so you're not mistaken, the direct injection in diesel trucks is not the same thing as DISI, do some research before you make false claims. You should work for Mazda's advertising department, really.

this is no where near his 1 stroke per cylindar thread...aparently 4 cyl are 4 stroke, straight 5's are 5 stroke, v10's are 10 stroke...and so on

Its a lost cause, all 1000 of his post are about going down on the Mazda DISI engine.

 

[HOBDisease]

Rofl sport6, unfortunately, you ARE correct, he's too far down to try to reel him back up. We'll just have to let nature take its course.

Money shot may change his mind.

mazda would be embarassed to have guys like Youngroids working for the advertising department. pretty sure they want people with basic reading comprehension, spelling skills and at least a fraction of understanding as to the last two decades of automotive engineering. none of which, as so many others with common sense in this thread have pointed out before me, our esteemed colleague has displayed.

[TX Speed 6]

Wasn't there also a thread where he claimed the seasons were fake and controlled by the govt. or some junk?

 

[my3needsaname]

The only direct-injected production gasoline engines that Mazda currently produces are the 2.0 liter NA DISI motor in the new base 3, the 2.3 liter MSR DISI, and the new RENESIS rotary engine, if I recall correctly...

That's bulls***. Why teh heck would Mazda do that? For fuel economy? Power? Then why not do it in teh better 2.3 to get more power and efficiency? This is why Mazda is not a winner anymore.

 

[GoFast]

who says the 2.3 is better? jsut because it's bigger doesn't automatically make it bigger.

 

[my3needsaname]

Touche...

I love you guys.

There is no reason in this modern day and age that a company is bound to fail on there first try at something. Get out of here with that lame as hell argument that you try to pass off as fact.

Obviously the system in diesels is differrent they inject under compression and we inject under intake. I said it's highly similar to the more modern systems for diesel truck injection that have been in place for over 10 years.

Yes I work on cars. No I am not a mechanic.

Hell no I never said that s***. Take your ****and go on home with that s***. I stated that I only want to run four stroke engines and thus my favorite design was an inline 4 cylinder. Obviously I know that there ain't no 10 stroke engines. Step up your reading comprehesion if that's what you thought was going on in that other thread.

Yea, all these roids I have been injecting have somehow given me an affinity for direct injection motors.
