INTERNATIONAL® S13®
INTEGRATED POWERTRAINThe International S13® Integrated is our most advanced, fuel-efficient and streamlined powertrain available in the LT®, RH™, HX® and HV™ Series. Capable of up to 515 hp and 1,850 lb-ft of torque, the S13 Integrated is comprised of an engine, transmission and aftertreatment system designed together to maximize integration between systems, while allowing each component to do its job. The result is a new standard of efficiency, profitability and sustainability for our on-highway and off-highway customers.
Designed and developed from the ground up by a global dream team of engineers and proven on more than 4 million miles over a variety of terrains, the S13 Integrated is the last diesel powertrain we will ever produce and without question — our best.
OPERATING ECONOMY
Through extensive testing, a new cylinder and piston head design with maximum cooling properties was created. This new double overhead cam design directly equates to less fuel being consumed. But that’s not all. Thanks to the new Dual Stage Aftertreatment system, the heavy and expensive EGR cooler is no longer needed to reduce emissions. Its absence means a more reliable and robust engine that maximizes exhaust flow through the turbo to enhance performance and efficiency.
Delivering the goods
The S13 Engine can operate at low rpm with high torque which equates to less fuel consumed while still delivering up to 515 hp and 1,850 lb-ft of torque. This incredible engine brings undisputed economy through its unique, clean burn technology.
HARD AT WORK
Keeping the driver comfortable, informed and empowered has been a mantra at International for decades as part of our DriverFirst™ Philosophy. The S13 Integrated Powertrain takes it a step further by offering a smooth and quiet operation with superior capabilities. In fact, full torque is available at only 900 rpm and the transmission’s wide overall gear ratio means optimal efficiency on a variety of terrain while still delivering low speed performance. And when descending, drivers can rely on the new compression release brake to deliver strong, secure braking power up to 470 hp.
Making the shift
The fully automated T14 transmission was designed in-house from the ground up. It’s a 14-speed overdrive transmission that is optimized to deliver peak fuel economy performance in direct drive (13th gear) during typical load, while still allowing the ability to go into overdrive when lightly loaded or empty. The transmission has an electronically controlled clutch actuator that works in sync with the engine to deliver faster, smoother shift performance. Since it does not consume air during complicated maneuvers — like when you’re backing a trailer into a tight loading dock – the driver never needs to stop and let the air recharge. The T14 also uses an integrated oil to water coolant system to optimize temperature regulation in both hot and cold environments.
AFTERTREATMENT SYSTEM
The entire powertrain was designed to allow each individual component — engine, transmission and aftertreatment — to focus on doing 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 focus on generating more power. Plus, no EGR during normal operations means 100% of the exhaust flow goes through the turbo allowing the use of a simple, more reliable fixed vane turbocharger.
Next-gen aftertreatment
Because there’s no EGR during regular operation, NOx must be treated a different way. To do this, the engineers developed an all-new Dual Stage Aftertreatment design that injects a first dose of DEF just downstream of the turbo in the evaporator tube and a second dose inside the aftertreatment container. Since a cooled EGR has been eliminated from the combustion chamber, much less soot or particulate matter is generated. This allows for extended service intervals and eliminates the need for active regens. In fact, the cleaner combustion cycle has so much less soot the engineers were able to eliminate the need for a diesel oxidation catalyst (DOC) in the aftertreatment system. Combined, the aftertreatment system provides a simple, reliable solution that’s easily serviceable.
EVERY DETAIL ENGINEERED TO PERFECTION.
EFFICIENT COMBUSTION CYCLE
The S13® Integrated engineers paid special attention to the design of the combustion chamber and exhaust posts to enhance the performance and efficiency of the engine. Through extensive testing, a new piston head with maximum cooling properties was created that when combined with a new double overhead cam design, directly equates to less fuel consumed.
STREAMLINED TRANSMISSION
The S13® Integrated’s T14 Transmission features a revolutionary design. The reverse gearing is accomplished by using the planetary gears which helps reduce the overall weight and size of the unit, making room for chassis packaging and PTO.
INCREASED PAYLOAD AND POWER
Thanks to comprehensive engineering and choice of materials, the S13 Integrated Powertrain is remarkably light in weight. This helps the HX Series achieve an outstanding payload capacity, along with improved fuel economy — attributes that can make a real difference to your bottom line. Plus, an International HX Series equipped with the S13 Integrated can be ordered with several different PTO options (including a dual option) installed directly at the factory and carrying the same warranty as the transmission.
S13® INTEGRATED IN MOTION
Several versions of the S13 Integrated Powertrain can be ordered — each with a different horsepower rating, allowing you to match the right engine to your specific application. All versions provide abundant torque at low RPM that is maintained through peak horsepower, giving drivers the muscle they need for the toughest jobs.
