Fuel Design as Constructional Element with the Example of Biogenic and Fossil Diesel Fuels

Different fuels, in detail: three blends from methyl esters of rapeseed oil, soy bean oil, and palm
oil; neat rapeseed oil methyl ester; a gas-to-liquid fuel (GTL); and two new diesel fuel qualities
from Aral and Shell (Ultimate resp. V-Power) were compared to reference diesel fuel (DF) with
focus on emissions.
Therefore, the regulated emissions carbon monoxide (CO), hydrocarbons (HC), nitrogen oxide
(NOx) and particulate matter (PM) and the non regulated particle size distribution were
determined. Additionally to the emissions the mutagenic potency of conventional reference
diesel fuel, biodiesel, Shell V-Power Diesel, and Aral Ultimate Diesel was tested.
In the result of all investigations it becomes clear that the potency of fuel systems engineering as
constructional element should be considered for the joint development of biogenic and fossil
fuels and engines.
