Abstract
A FTIR in-vehicle on-road emission measurement system was installed in a EURO 2 emissions compliant SI car to investigate exhaust emissions under different urban traffic conditions. The real time fuel consumption and vehicle traveling speed was measured and logged. The temperatures were measured along the exhaust pipe so as to monitor the thermal characteristics and efficiency of the catalyst. Two real world driving cycles were developed with different traffic conditions. One (WP cycle) was located in a quiet area with few traffic interference and the other one (HPL cycle) was in a busy area with more traffic variations. The test car was pre-warmed before each test to eliminate cold start effect.
The driving parameters were analyzed for two real world cycles. The WP cycle had higher acceleration rate, longer acceleration mode and shorter steady speed driving mode and thus harsher than the HPL cycle. The CO, THC, NOx CO2, benzene and other hydrocarbon emissions were higher for the WP cycle. The comparison with EU legislation shows that the CO and THC emissions from both real world cycles could meet the legislated limit but the NOx emissions from both cycle exceeded the legislated emissions when the engine was hot. The research analyzed the elements that affect urban traffic emissions and will be useful for a better traffic management to reduce emissions. The data of this research can be used for the prediction of emissions in cities.
