Effect of Diesel Fuel Composition on Fork-Lift Truck Emissions

Abstract

<div class="htmlview paragraph">Diesel fork-lifts are often preferred over LPG due to lower costs and superior fire safety in in-door use but exhaust causes problems.</div> <div class="htmlview paragraph">Air quality was measured with standard and reformulated diesel fuel in a warehouse where diesel fork-lifts operated. Sulphur was 605 ppm for the standard and 7 ppm for the reformulated fuel. Aromatics were respectively 31 vol-% and 12 vol-% and 95-% distillation points 352 °C and 286 °C.</div> <div class="htmlview paragraph">Fuel reformulation reduced particulates in the ware-house air by 40 %, particulate SOF by 50 % and mutagenicity of SOF by 80 %. NO, NO<sub>2</sub>, SO<sub>2</sub> and PAH concentrations were low. Irritation and the possibility of long-term health problems reduced.</div>
