Abstract

This article presents a comparison of CO₂, CO and NO_x emission from Saab 9-3 1.9 JTD and Fiat Bravo 2.0 JTD engines. The tests were conducted on the same route and reflect real driving emission from following passenger cars. Fiat Bravo engine is an evolution of 1.9 engine redeveloped to meet EURO 5 requirements. Despite cylinder diameter enlargement and increased fuel consumption harmful exhaust gases components were significantly reduced. Both of the engines had not exceeded the considered regulations. The results were obtained using SEMTECH DS device from PEMS (Portable Emissions Measurement System).
