ABSTRACT
Oxygenated fuel blends produce a significant reduction in emissions of particulate matter from diesel engines. CETANER™ is an oxygenated diesel fuel additive developed by Air Products and Chemicals Inc., which can potentially be produced from syngas. CETANER is miscible in diesel fuel at high concentrations, and has very high cetane response. As a result, CETANER™ also has much potential as an additive for diesel particulate matter emission reduction. This chapter evaluates methyl soyate, as well as CETANER™ and several linear ethers, to review their effectiveness as at reducing particulate matter emissions from diesel engines. For each oxygenated diesel fuel blend, several critical fuel properties were evaluated. Engine performance and emission testing was also completed for each oxygenated fuel blend. Evaluations were performed using a single-cylinder indirect injection (IDI) Yanmar TS-180 diesel utility engine with a continuous rating of 15 HP at 2400 rpm, coupled to a Clayton CAM-50 water brake dynamometer.
