Emissions From a 5.9 Liter Diesel Engine Fueled With Ethanol Diesel Blends 2001-01-2018

A certification diesel fuel and blends containing 10 and 15 volume % ethanol were tested in a 5.9-liter Cummins B Series engine. For each fuel blend, an 8-mode AVL test cycle was performed. The resulting emissions were characterized and measured for each individual test mode (prescribed combination of engine speed and load). These individual mode results are used to create a weighted average that is designed to approximate the results of the Heavy-Duty Transient Federal Test Procedure. The addition of ethanol was observed to have no noticeable effect on the emission of NOx but produced small increases in CO and HC. However, the particulate matter was observed to decrease 20% and 30% with the addition of 10% and 15% ethanol, respectively.
