LAKE FOREST, Ill. (March 24, 2015) — Tenneco Inc. is supplying key aftertreatment emissions technologies to Kubota Tractor Corp., a global manufacturer of engines and equipment for agricultural and industrial applications.
Tenneco said it is in serial production with a complete selective catalytic reduction (SCR) system that meets both Tier 4 Final and Stage IV emissions regulations for Torrance, Calif.-based Kubota's 3.8L diesel engine and all-new 6.1L engine for new agricultural equipment, which is slated for production later this year. This is the first SCR system to be produced at Tenneco's manufacturing facility in Osaka, Japan, according to the company.
Lake Forest-based Tenneco's SCR system includes a high-performance dosing technology that features a compact airless injector, a pump that enables unique return flow cooling, technology for rapid thawing, and complete control and diagnostics that seamlessly integrate with the engine management. Additionally, the company reported that it is providing full system integration capabilities to Kubota — supporting enhanced fuel economy and aftertreatment performance through weight reduction, optimized thermal management and efficient system design.
