Abstract
Systems and methods for reporting data based on monitored emissions levels. An exemplary system automatically provides emissions level data acquired from an engine operating in a roadway vehicle while the vehicle is in motion. Data is made available for vehicle approval by a roadway inspection authority. For example, NOx emissions may be monitored with a sensor positioned in the engine exhaust flow path. Embodiments of the invention provide solutions to reduce time delays associated with inspections.
