Inside the International S13 powertrain | FE Unscripted

As the International S13 powertrain rolls out to customers, the OEM also rolled its new engine, transmission and aftertreatment package out to TMC, held earlier this month in New Orleans. David Crowe, S13 integrated sales manager, International Trucks, walked us around the powertrain that is characterized by its dual overhead cam engine design, which aims to improve combustion efficiency by increasing the compression ratio. This approach reduces the need for complex components, such as the EGR cooler, which has been eliminated.
"When you look at what an EGR cooler is doing, it's all about trying to control your levels of NOx being produced in that combustion process. What you're actually doing is you're introducing roughly 20% dirty air back into the cylinder--things like carbon and soot that gunk up the inside of the engine--and also sending all of that waste downstream," Crowe explained. "By eliminating that, you clean everything up and you're eliminating those failure points for fleets."
The engine's design also simplifies the system by lowering fuel pump pressure and employing a fixed geometry turbo instead of a variable geometry turbo. Crowe also noted that by achieving a more complete burn of diesel fuel, emissions of soot are reduced, and NOx emissions are managed through an advanced aftertreatment process.
There are plenty more S13 powertrain specs to talk through. Watch the video above for all of the horsepowered details.

its the new scania Powertrain, you gonna be blown away by its performence/efficiency ,even the Freightliner cant hold with it.

Might be getting mine in November. 726,000 miles on my A26 and still doing great.

Hi Jason. I believe I heard a nervousness in you voice there talking about after treatment systems with International. Can’t blame you after the Mass EGR fiasco. Time and mileage will tell if this new system will work. Seems promising though 👍

[@Rimrock300]

Great info. That guy is great at explaining things in an understandable way

[@lanzonova]

100% Scania powertrain. 👍

[@JDXRider1]

Great job David Crowe!

[@anastasiszaroliagis5066]

Looks like my G 500 Scania..😮

[@jeffreyurquia4379]

It's because is made by Scania, is based on the DC13 Super.

[@janfswedane]

1st step for Scania reentering the US truck scene.... Watch out domestics...

[@86SVA]

Americans discover European technology and try to pass it off as their own 😂

[@roberthale8407]

Why drop the rail PSI? Higher injection pressures will help reduce emissions. Odd...........

[@henryblanton6992]

Top two Trucks in the World: #1: Volvo; #2: Scania. Swedish Trucks do it Right from the Get Go. 😎

What a nightmare

[@Rimrock300]

Certainly is to the competition. Certainly is.
