Abstract
This paper presents an evaluation of results of the exhaust emissions and fuel consumption of automotive vehicles examined in Poland for type approval in 2001-2002 (until the end of February current year) and compared to the results obtained in 1996-1998. The previous (Euro II Directive 96/69 EC and Regulation 83.03 ECE) and new (Euro III/Euro IV Directives 98/69 EC, 1999/102/EC and 2001/1 /EC, and Regulation 83.05 ECE) procedures used in the approval tests in the presented scope have been described and several results of these tests conducted in Poland have been evaluated. The aim of this work was to verify state-of-the art automotive technology, with respect to fulfilment at emission limits and EOBD systems functioning. The results of CO, HC, NOx, PM and CO2 emissions, achieved during tests performed on a chassis dynamometer following Euro II and Euro III/IV procedures using the bag analysis method, have been presented and discussed. The tests were undertaken on over 200 vehicle types of European, Japanese/Korean and the US manufacture and are commonly found on roads in Europe.
