Head to head oil burners comparison

I found this article very interesting.

These engines are so different but yet again so similar.

The most striking for me is:

Dis-similar:

One is a 60 degree; one is a 90 degree.

One is a single VGT turbo; one is a modulated two stage turbo.

One is a V8; one is a V6.

One has 5 shots / combustion; one has 8 shots / combustion.

One is a big bore small stroke; one is a small bore big stroke.

One does not use a Bosch fuel system. :E



Simular:

Both CGI blocks.

Both 4 valve/ cylinder.

Both 29,000 psi common rail.


What I find most strange is that Cummins for the most part is and always has been a small bore big stroke engine company. But not on this engine!! They went the other way around? :h

Where as the "Itallion" engine company DID go this route!! :h

WHAT THE...........................????????????

Yes, yes, yes I know, I know. Most all of Cummins engines are an I design and this one isn't. But still they could have made a big stroke small bore much like the Ecodiesel did. Wonder why? Did they want a more car "like" performance engine for their half ton market?

Cool times and strange times we have going on!! :)

    Now the new 1/2 tons are dropping as much power to the ground as the big diesels of 10 years ago!
    Between the new trucks and the current crop of muscle cars out there, it's a great time to be a gear head!
    Cripes, I got a 425 factory hp SRT that just rips and it will get its doors blown off by any number of newer and some smaller displacement vehicles on the showroom floors now.


    LOL! I know how you feel. Use to ride around in the beloved muscle car feeling good, head held high and now ride around slouch down looking through the steering wheel hoping that Honda pulling up beside you at the light don't wanta go...HAHAHA!!! Boy how times have changed.

    So the American made engine goes in the Japanese brand truck, the Italian engine goes in the American truck??? No wonder why we have brand loyalty issues.

    Actually a bit more than that. The Cummins has a British Holset Turbocharger and the original Cummins 5.9.engine was co-developed by Fiat Powertrain now part of IVECO

    The ram 1500 EDiesel won't beat the Cummins in anything but fuel mileage! Two totally different vehicles. The Nissan has a 6 lug 10.5" AAM axle the ram a 9.25". The Nissan is a 2500 badged as a 1500 and far more capable than the Ram 1500. If you care to compare the Ram 2500 to it then it begins to not look so good.

    Please note the Nissan looks to be a much better truck then before and with the Cummins it will be hard to beat the fuel mileage compaired to the 6.7 Cummins and Powerstroke or the Duramax. But to compare it to any standard 1/2 ton is not fair.

    I looks forward the the head-head tests. Ram makes a pretty nice 1500, last time I looked at a Nissan, they seemed a little behind compared to the other 4 1/2 ton trucks. Maybe some body & interior updates will come with the new engine.

    The compression ratio is dropping in diesels because its the only way to reduce NOX.
    sad because efficiency drops a bit

    That's very true IB.

    But since they will both have the 1500 badge on the fender they will both be fighting for the same consumer dollars in the half ton oil burner world. Much like today with the Ecoboost and the Ecodiesel.

    Another thing I find interesting is the compression ratio Ram picked. They are getting lower and lower to pack that air in with the turbo.

    I wonder if GM is going to release their .75 Duramax now?

    Gotta keep in mind these engines were developed or put in trucks for different purposes. The little 3.0L V6 was supposed to be, and is, the mpg champ.

    The 5.0L Cummins was made for more capability.
