Emissions databases from off-road diesel-powered equipment suffer immensely from insufficient real-world activity data. Moreover, there is little information available regarding the validity of standardized dynamometer engine test cycles that are currently used for emissions certification. The present study was initiated in order to fill the current void in the off-road equipment testing cycles and the consequent lack of real-world emissions data that is needed for accurately modeling emissions inventories. For this study, onboard engine data was logged from four off-road vehicles in order to generate transient test cycles that could be used to simulate real-world operating conditions for exhaust emissions research. The off-road diesel-powered equipment targeted for this study was selected to be representative of the major off-road diesel emissions contributor in California.
