Petrović et al. | Why Portable Emissions Measurement Systems (PEMS)? New tehnologies for extra low engine emissions put new question: does emission testing in standard laboratory corresponds to real life emission of vehicle in-use? To answer this question it is necessary to measure vehicle in-use emission. However, such testing is very complex and still there is not reliable and appropriate portable emission measurement system which can be used in real-service vehicle operation. | |
