RELATIONSHIP BETWEEN PARTICULATES AND HC/BLACK SMOKE EMISSIONS IN A DIESEL ENGINE
It is possible to classify the substances collected in a filter which uses a tunnel to dilute the exhaust gases of a diesel engine into substances which are insoluble in organic solvents (hereafter called Dry Soot) and soluble substances (hereafter called SOF (Soluble Organic Fraction)). The methods for measuring particulates stipulated by the EPA include measuring apparatus and driving modes and are complicated; they are not necessarily suitable in this analysis due to the techniques implemented to counteract exhaust gases. Consequently, if this could be replaced by a simple method of measurement, it would become an effective way of enforcing exhaust gas reduction countermeasures. The authors used Dl engines which were either naturally aspirated or equipped with turbo-intercoolers to investigate the relationship between HC and black smoke, and particulates and particulate exhaust characteristics; it was clear that it is possible to evaluate the measures used to reduce particulates by measuring HC and black smoke.
