Introducing the International S13 Integrated Powertrain
January 31, 2023 | News | By Tri-County International Trucks
A clean sheet of paper and decades of experience. That’s what the engineering team started with when they began work on the International® S13 Integrated Powertrain.
UP TO A 15% BOOST IN EFFICIENCY.*
The S13 engine can operate at low RPMs with high torque, which equates to less fuel consumed while still delivering up to 515 horsepower and 1,850 lb.-ft. of torque. Thanks to a new dual stage aftertreatment system, the heavy (40-50 pounds), expensive (approx. $2,500) and finicky EGR cooler is no longer needed to reduce emissions. Its absence helps the S13 be the lightest 13-liter diesel engine providing maximum performance and efficiency.
*Compared to the 2017 International A26 engine in a 2017 International LT with aero package. Actual customer results may vary due to various factors, including but not limited to, truck specifications, weight of the vehicle, predictive features, environmental conditions, etc.
MAKING THE SHIFT.
The all-new T14 transmission was designed from the ground up to be a fully automated manual transmission. It’s a 14-speed overdrive transmission that is optimized to deliver peak fuel economy performance in direct drive (13th gear) during typical load.
The all-new, fully automated T14 is a 14-speed overdrive manual transmission that is optimized to deliver peak fuel economy performance in direct drive during typical load. Since it does not consume air during complicated maneuvers – like backing a trailer into a tight loading dock – there is no need to stop and let the air recharge. It also uses an oil-to-water coolant system to optimize temperature regulation in both hot and cold environments, which is one reason the T14 is able to achieve a gross combination weight (GCW) of up to 240,000 pounds.
NEXT-GEN AFTERTREATMENT.
Each component can focus on what it does best. Eliminating the EGR cooler is a prime example. Instead of trying to control NOx emissions inside the cylinder, the engine operates with zero EGR during regular operation so it can generate more power. Removing the EGR produces much less soot or particulate matter, allowing for extended service intervals and eliminating the need for active regens. The aftertreatment system provides a simple, reliable solution that is easily serviceable.
The International® S13 Integrated Powertrain was verified in some of the most challenging environments in North America. It also spent time inside a state-of-the-art facility that can
simulate 10 years of extreme temperature ranges that a truck may encounter out on the road.
