Kenworth offering PACCAR MX-13 CARB-compliant engine

The PACCAR MX-13 CARB-compliant engine will be available in the Kenworth T680, T880, and W990, with production slated for Q4 2024.

Kenworth introduced a California Air Resources Board (CARB) compliant version of the PACCAR MX-13 engine for its T680, T880 and W990 trucks. Production will begin in the fourth quarter of this year.

Kenworth tells us that the PACCAR MX-13 CARB-compliant engine features new aftertreatment hardware that meets stringent California low nitrogen oxide (NOx) emissions requirements. To meet the more stringent CARB emissions requirements, the company adds the MX-13 CARB engine utilizes a twin-canister selective catalytic reduction (SCR) aftertreatment along with more optimized emissions controls systems while continuing to provide excellent reliability, performance, and efficiency.

“Our customers are looking for better options to successfully navigate the complexities of the evolving regulatory landscape and Kenworth models equipped with PACCAR’s MX-13 CARB-compliant engine achieve compliance with stringent emissions regulations while also delivering a solution that drives increased engine efficiency and enhanced fuel economy,” said Kevin Haygood, Kenworth assistant general manager for sales and marketing.

The PACCAR CARB-compliant MX-13 engine is available in two options: a 510-HP rating with 1,850 lb.-ft of torque and a 455-HP rating with 1,650 lb.-ft of torque.
