Abstract
Southwest Research Institute has developed several hew procedures and analytical tools that can aid manufacturers in the development and integration of new control technologies to meet Super-Ultra-Low Emissions Vehicle (SULEV) standards. The new SwRI technologies include: A Computer based system (called ERIC) that interacts with the engines electronic control unit to allow for smooth engine calibration integration with aftertreatment systems; A Flexible Exhaust Evaluation Rig (FLEXER) that generates a wide range of feedgas conditions to cost effectively evaluate a large matrix of aftertreatment technologies or sensors in a short time; and A Fuel/Oil Catalyst Aging System (FOCAS) that can independently determine the effects of fuels and lubricating oils on aftertreatment performance.
