I’m excited to introduce David Stark as this week’s Case IH expert blogger. David is a Case IH commercial product trainer, responsible for training dealers on Case IH engines and tractors. I’ve invited him to walk us through the updated Case IH high-horsepower diesel engines , which feature the world-class design innovations of FPT Powertrain Technologies, that you will find in the 2011 Steiger, Magnum, and Puma tractor models. He grew up on a farm in central Illinois and enjoys using his farming experiences and Case IH knowledge to show you how you can make the most of Case IH equipment on your operations.
While talking about Case IH high-horsepower engines at the Ag Connect Expo in Atlanta, Ga., a farmer commented to me that he, like most farmers, puts a lot of hours on his tractors. He wanted to know if our new Tier 4A Case IH engines are built to last.
The quick answer to this is, “Absolutely!” But, you probably want to know why, so I’m going to walk you through some key features of our new Case IH engines and explain how they work together to provide today’s farmers with the power, performance, and fuel efficiency needed to get the job done. To begin, all our new Case IH 6.7L, 8.7L and 12.9L high-horsepower engines:
In addition, to comply with the EPA’s Tier 4A mandates (effective January 1, 2011), Case IH high-horsepower engines are equipped with Selective Catalytic Reduction (SCR) technology, which my colleague, Leo Bose, details in the Tier 4A Engine Technology Overview blog post. SCR emissions technology operates separately from the main engine function and does not compromise the combustion process. This ultimately eliminates emissions as mandated, while also maximizing fuel efficiency and minimizing maintenance costs. Compared to previous engine designs, it also enhances available engine horsepower, torque, and overall performance.Each Case IH high-horsepower engine was built with specific features that lend to their improved responsiveness and fuel efficiency.
Here is a little more information about each engine:
The 12.9L is our largest engine and powers the 2011 Steiger tractors from 400hp to 600hp. Two versions are available to match the engine-to-horsepower requirements – a single-stage turbocharger for 400hp to 500hp models, and the new two-stage turbocharger for the Steiger 550 and larger. The single-stage turbocharger features a proven wastegate design that regulates the maximum speed of the turbocharger, provides increased throttle response and helps build engine boost faster. The two-stage turbocharger provides two separate turbochargers that work in tandem to deliver the right amount of boost, regardless of engine speed.
An 8.7L powers the 2011 Magnum and Steiger tractors ranging from 235hp to 350hp and is equipped with a wet cylinder sleeve design, which ensures the highest level of cooling and overall serviceability. Its single fully rollered overhead camshaft eliminates push rods and tappets for simpler design and reduced friction. This makes the engine turn over with less effort, which in turn reduces fuel consumption and minimizes friction to increase engine life and horsepower.
2011 Magnum and Puma tractors from 130hp to 230hp use the 6.7L engine. It’s built with a cross flow cylinder head design that improves air flow by bringing in fresh air on one side of the engine and emitting hot exhaust gases on the other side. This promotes combustion, therefore enhancing fuel efficiency and engine responsiveness.

Next week’s Case IH Expert blog post will feature Enrique Guzman of FPT Powertrain Technologies, who will discuss the partnership between Case IH and FPT Powertrain Technologies and development of the of the SCR solutions for the new generation of Case IH high-horsepower Tier 4A-compliant engines. Stay tuned.
