Eaton’s valvetrain portfolio for diesel off-highway vehicles now features cylinder-deactivation (CDA) technology that allows for variable valve actuation with hydraulic lash adjustment (HLA) functionality that enables precise valve lift control to, when coupled with engine braking capability, help reduce emissions and improve fuel economy. CDA is designed to increase the exhaust temperature at low load to allow nitrogen oxide (NOx) aftertreatment systems to quickly reach peak efficiency range of 500 to 750 degrees Fahrenheit. HLA technology also is engineered to optimize valvetrain performance by providing precise valve timing over the vehicle’s life while reducing noise and eliminating service for manual valvetrain lash settings.
