New 5-liter V8 Diesel Engine Launch

[Texas Ted]

Browsing around this morning I found this article for those who haven't seen it yet.



Cummins Inc. (CMI) announced the launch of a new a 5-liter V8 diesel engine, ISV5. 0http://finance. yahoo.com/news/cummins-isv5-0-engine-213502996.html, which will be produced from the fourth quarter of 2014. This engine will be installed in power pickup-and-delivery vehicles, other light- and medium-duty trucks, school buses and motorhomes. The new engine will offer enhanced fuel efficiency and performance and help reduce emission.



Cummins ISV5. 0 engine is armed with industry leading technology and offers better performance at a low total cost of ownership to customers in North America. The ISV5. 0 will be produced in the Columbus Engine Plant, along with the 5. 0L V8 Turbo Diesel for pickup trucks.



Cummins ISV5. 0 engine comes with a compacted graphite iron (CGI) cylinder block, high-strength aluminum alloy heads, forged steel crankshaft and composite valve covers. Thus, it offers high durability along with lightweight packaging. With these features and the dual overhead camshafts, Cummins ISV5. 0 engine helps minimize roughness, noise and vibration. In addition, the ISV5. 0 engine is small enough to conveniently replace V8 or V10 gasoline engines.



The new ISV5. 0 engine of Cummins will be available to customers in the U. S and Canada. It will meet the U. S. Environmental Protection Agency’s EPA) emission requirements related to NOx and PM. Cummins also expects that the engine will satisfy the greenhouse gas standards till 2016, and 2015 Air Resources Board standards, including on-board diagnostics.



In September, Cummins announced the introduction of the G Series platform, a global heavy-duty engine platform. It features an in-line six cylinder engine and will be available in 10. 5 and 11. 8 liter displacements. The G Series platform is expected to meet the global market demands and emission standards both on- and off-highway.



Cummins currently has a Zacks Rank #3 (Hold). Other stocks that are performing well in the industry include TRW Automotive Holdings Corp. (TRW), Allison Transmission Holdings, Inc. (ALSN) and Denso Corp. (DNZOY). All these are Zacks Rank #1 (Strong Buy) stocks.

Thats why I don't like the Duramax, aluminum heads. I wonder how many changes they'll make, like the Duramax did, and every time was supposed to be the fix for the problems.

The duramax has proven to be a pretty good engine, it has had issues but really nothing more than Cummins. I am not really aware of any issues directly related to the aluminum heads, thou I don't like them on principle for a HD diesel motor.

I still think that the 5. 0 V8 platform is too big for a 1/2 ton, a 3. 0 V6 or I6 would be a much better setup IMHO.

I absolutely agree, and I would still choose a Duramax over any of Ford's last three efforts.

NO WAY BROTHER!! I don't think any cummins engine has had problems like the duramax did. Just start with the overheating issue at the dmax beginning. I don't think dissimilar metals belong in Diesel engine major components. However I don't know how the CGI/ aluminum combo will be.

 

[RVTRKN]

Over heating is Poor design, but aluminum heads on cast iron is a major mistake on a diesel due to high compression. DM has had several changes since it was introduced on the heads and the way they are attached.

 

[cerberusiam]

The Durmax is a solid engine but its operating window is VERY narrow. Stick the thermostat and overheat it once, push the power limit a little too high, and just figure on tearing the top end off and planing the heads plus all the gaskets. The expansion\contraction rates and deformation index of aluminum compared to cast iron is so radically different it will ALWAYS be a failure point. Adding more bolts to hold the shape hits a limit becuase then ther eis not enough metal to retain sturctural integrity. Aluminum heads on ANY engine is cheap way to go and has a limited life expectancy.



The article pretty much defines the market, low TCO. Its going to be a cheap throw away engine with a finite lifetime best suited to light duty pssenger car use. Don't expect to work it hard or your pocket book will suffer. TCO is one of those metrics that can be used to convince or disuade, all depends on how you look at it. The TCO on a cast iro block\head engine over a long period WILL be lower than the short term they are using for a basis. Recylce it every 3 years and it looks good, keep it 10 years and the bottom line is not so good.



Unfortnately, that is the way everything is built now.
