Summary:

The European driving cycle, deleting the first 40 seconds of idle after the start up phase, and the US FTP 75 cycle are compared in this paper. The paper presents an analysis of emission tests for CO, HC and NOx measured during tests performed on a chassis dynamometer under laboratory conditions. The tests are reviewed and the results discussed.The objective of the study was to determine the influence of the test cycle on the measured emission of CO, HC and NOx, and the changes of fuel consumption at the initial phase of engine operation. Differences in catalyst warm up rates when running NEDC, ECE + EUDC and FTP 75 cycles are demonstrated.Methods of reduction in these harmful emissions and the results of tests with new technologies targeted at the reduction of CO, HC and NOx under cold start are also discussed
