APBF Task Completes Joule Milestone
Summer 2005
NREL recently completed a Joule milestone under FCVT's Advanced Petroleum-Based Fuels (APBF) activity. Working with Volvo/Mack and Sturman Industries, NREL scientists used parametric analysis and modeling to determine the effect of fuel properties at a molecular level on advanced combustion regimes, in particular, homogeneous charge compression ignitions. This research increases our knowledge and understanding of the relationship between molecular structure and high-efficiency clean combustion regimes.
The APBF activity is directed at overcoming technical barriers to the use of advanced fuel produced from petroleum as well as petroleum blends with renewable and synthetic fuels.
APBF Research Supports New EPA Non-Road Diesel Rule
Summer 2004
When the EPA drafted its landmark emission regulations for non-road vehicles, it relied heavily on research generated by the Diesel Emission Control -Sulfur Effects (DECSE) and Advanced Petroleum Based Fuels - Diesel Emission Control (APBF-DEC) studies. These NREL managed projects focus on the effects of sulfur in diesel fuel on emission exhaust control systems, and leverage the participation of industry co-sponsors including engine and vehicle makers, the petroleum industry, emission control suppliers, and state and federal regulatory agencies.
The Bush Administration's Clean Air Non-road Emissions Rule, which was adopted May 11, 2004 is expected to reduce harmful emissions from non-road vehicles such as farm and construction equipment by 90%. It will also reduce the amount of sulfur in diesel fuel by 99%—enabling engine manufacturers to take advantage of emission control devices that are affected by sulfur levels.
