Heavy-Duty Diesel Emissions as a Function of Alternate Fuels 830377
Emissions from a modern heavy-duty Diesel truck engine were characterized with five different fuels during transient and steady-state operation. A control fuel (Phillips D-2) was used for baseline emissions, and as base stock in three alternate fuel blends containing EDS or SRC-II middle distillates, or used lubricating oil. The fifth fuel tested was neat soybean oil, heated to 145°C. HC, CO, NOX, and particulate emissions were similar for this engine on all fuels tested, with the exception of higher particulates for the soybean oil and higher NOX for the SRC-II blend.
