“E diesel” Program What is “E diesel”??
Definition And Key Properties of “E diesel” Fuel “E diesel” is defined as a blend of up to 15% anhydrous Ethanol, up to 5% Special Blending Additive (with cetane/lubricity enhancer), and at least 80% #2 diesel fuel. The Fuel Blend Has A Lower Pour Point Temperature Than Conventional Diesel Fuel. Minimum Fuel Oxygen Content = 2.7%
Engine Tests 8 Mode Steady State Emissions Test Federal Smoke Cycle Test Unregulated Emissions Testing - (31 potential toxins) Durability Tests Cold Room Tests
Vehicle Tests - Further field testing to compliment the work of the University of Illinois project - Vehicle cold room tests - Vehicle hot room tests comparing fuel cooler performance/vapor lock effects between # 2 diesel and E diesel mix - Verification work for using E diesel as factory fill
Vehicle Tests (Continued) -Bench test/analysis to evaluate seal/material compatibility -Analysis on fuel lines, fittings, fuel tank, and fuel from field machines -Flash/flammability tests, spark arrestors, safety verification

John Deere E-diesel Research Program The research will be performed covering engine families using three injection system technologies: - Rotary - High Pressure Common Rail (HPCR) - Electronic Unit Injector(EUI) along with fuel additives from our major suppliers

Regulated Emissions Summary • All engines w/ all test fuels/additives meet EPA’s Tier II non-road regulated smoke and emissions requirements • More than 75% of the regulated smoke and emissions data for E diesel blends indicated improvement • The reductions of Particulate Matter (PM) and visible smoke were significant and consistent for the E diesel blends
Compound Abbreviation Individual Hydrocarbons (IHC) 1,3 – Butadiene Methane Benzene Toluene Ethylbenzene m&p–Xylene o–Xylene Hexane Methyl ethyl ketone Styrene
Compound Abbreviation Soluble Organic Fraction of PM (SOF) Aldehydes and Ketones (ALD) Formaldehyde Acetaldehyde Acrolein Propioandehyde Methyl Ethyl Ketone Ethanol (ETH) 1-Nitropyrene (nPAH)
Compound Abbreviation Individual PAH (PAH) Naphthalene Acenaphthene Acenaphthylene Fluorene Phenanthrene Anthracene Fluoranthene Pyrene Benzo(a)anthracene Chrysene Benzo(b)fluoranthene Benzo(k)fluoranthene Benzo(a)pyrene Indeno(1,2,3-cd)pyrene Dibenz(a,h)anthracene
Unregulated Potential Toxins • Comparison of 423 data points • 58% of the E diesel blends recorded equal or reduced emissions compared to the certification fuel • In general: - the acetaldehydes group and ethanol emissions substantially increased with the ethanol blends - benzene and 1,3 butadiene were substantially reduced with the ethanol blends
