International Motors’ S13® Powertrain Approved for Renewable Diesel

Sustainability is more than just a goal for International Motors—it’s the driving force behind their innovation. The company recently announced that the International® S13® Integrated Powertrain has been officially certified and approved for use with renewable diesel. This milestone underscores International Motors' customers in their pursuit of zero-emissions goals while enhancing performance and efficiency.

Renewable diesel, commonly referred to as R100 or R99, or hydrotreated vegetable oil (HVO), is emerging as a transformative solution in the realm of eco-friendly fuel. Unlike traditional petroleum diesel, renewable diesel is derived from sustainable sources such as recycled vegetable oils, tallow, and used cooking oil. Its chemical structure closely resembles that of conventional diesel, enabling it to serve as a direct replacement without compromising performance.

One of the key advantages of renewable diesel lies in its production process. Through hydrotreatment, fats, oils, and agricultural waste undergo a reaction under high pressure and temperature with a hydrogen catalyst. The outcome is a cleaner-burning fuel that reduces carbon emissions and operates seamlessly with existing S13 diesel engines.

According to Chet Ciesielski, Vice President of National Fleets and Truck Equipment Manufacturers at International Motors:

"Given the industry's ambitious sustainability targets, International aims to provide customers with various options to support their unique carbon reduction goals. Our mission is to accelerate the impact of sustainable mobility, offering incremental solutions tailored to each customer's objectives."

Renewable diesel distinguishes itself from biodiesel due to its paraffinic nature, meaning it lacks oxygen compounds. This characteristic enhances cold flow properties, making it suitable for diverse climates. Additionally, its high Cetane number ensures a cleaner, more efficient burn, positioning it as a high-quality, low-carbon alternative to traditional diesel fuels.

Michael Noonan, Vice President of Engineering at International Motors, adds:

"Renewable diesel fuel meets ASTM D975 Diesel Fuel Specification and EN 15940 Paraffinic Diesel Fuel Specification. It offers superior storage capabilities compared to biodiesel, lower sulfur and ash content than petroleum-based diesel, and significantly reduced tailpipe emissions—making it an invaluable tool for fleets striving for sustainability."

The International S13 Integrated Powertrain, available in the International LT®, RH™, HX®, and HV™ Series trucks, represents the pinnacle of International Motors' engineering excellence. Delivering up to 515 horsepower and 1,850 lb-ft of torque, this integrated system—comprising an advanced engine, T14 transmission, and state-of-the-art aftertreatment system—is designed for optimal efficiency and performance.

By integrating these components, the S13 Powertrain sets a new industry standard, enhancing profitability while advancing sustainability. This approval for renewable diesel use aligns with environmental goals and ensures that International Motors' customers continue to benefit from unmatched reliability and efficiency.

This milestone, along with International’s other sustainability efforts, demonstrates how the International S13 Integrated Powertrain and renewable diesel can power fleets toward a cleaner future.
