Amostragem do material particulado e fração orgânica volátil das emissões em motor ciclo diesel sem a utilização de túnel de diluição Sampling of particulate matter and of the volatile organic fraction of emissions from a diesel cycle engine without the use of dilution tunnel

Abstract

Using a sampling method of particulate matter (PM) without the use of a dilution tunnel allows for evaluations of the volatile hydrocarbons (HC) in the emissions of diesel cycle engines. The procedure in this work applied a heated filter with temperature controlled. The volatile compounds are condensed at low temperature, allowing for evaluation of the HC by thermal desorption of the PM and for analysis of the condensed compounds of the exhaust gases.
