Fuel quality effects on particulate matter emissions from light- and heavy-duty diesel engines
This paper gives an update of Shell`s ongoing research on correlations between diesel fuel quality and particulate emissions in both heavy and light duty applications. An exhaust oxidation catalyst selectively decreases the particulate hydrocarbon fraction, leaving the fixed carbon fraction unaffected. This overall particulates reduction mechanism explains why particulate emissions from catalyst vehicles are less sensitive towards changes in fuel quality. An attempt has been made to explain the differences observed between particulate emissions from heavy- and light-duty engines. It is tentatively concluded that differences originate mainly from intrinsic differences between the heavy- and light-duty test cycles. 27 refs., 14 figs., 5 tabs.
