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.
“We’re proud to support Kubota by providing aftertreatment solutions that deliver improved engine performance,” said Jeff Jarrell, vice president and managing director for Tenneco Japan and Korea. “Tenneco’s SCR technology and systems integration expertise are helping Kubota successfully meet stringent emissions targets for its current and future agricultural tractor as well as construction equipment platforms.”
Emission controls supplier Tenneco said it supports customers in North America, Europe, Brazil, China, India, South Korea and Japan “in meeting increasingly stringent emissions standards taking effect worldwide.” The firm designs, manufactures and markets clean air and ride performance products and systems for automotive, commercial truck and off-highway original equipment markets and the aftermarket under the principal brand names Monroe, Walker, XNOx and CleviteElastomer.
