Cold start emissions of Heavy Duty Vehicles

Emissions of Heavy Duty vehicles (HDV) are becoming more and more important as emission levels of passenger cars drop significantly. In contrast to passenger cars, where cold start extra emissions are investigated extensively, only few data is available for fuel consumption and emissions after cold starts for HDV. On the chassis dynamometer emissions in real world urban driving cycles for HDV have been measured at operating temperature and after a cold start. The measurements show significant increases of energy consumption and emissions. For example fuel consumption is about 18% and particle mass emissions are about 30% to 50% higher at cold start.
