This report is about an engine and a truck. They have been tested with regard to smoke density in a test bench and at a chassis dynamometer respectively according to ECE R24 Regulation, A30 Regulation and A40 Regulation. Two diesel fuels were used: CEC Reference fuel, and Swedish environment class 2 diesel fuel. This investigation has been performed within the test series, which is contracted between SwEPA and ASB. The commission is to perform smoke density tests with two engines/vehicles according to the ECE R24 Regulation, the Swedish A30 Regulation and A40 Regulation with two different diesel fuels and at different environment temperatures. The opacity test system is an Electra Control Diesel Test System DST 200-DX, which complies with ECE R24 Regulation. It allows measuring at optional points of time and at free acceleration test. The blackness of the filter paper due to soot is determined by a reflectometer head and the soot content of the exhaust gas is calculated from the paper blackening and the effective length. The results indicate that there is a good correlation between the filter blackening and the opacity methods, furthermore that there is a difference in results due to fuel quality.
