Engine Emissions Testing of Straight Vegetable Oil

The goal of this project is to test locally grown Soybean, Canola, and Camelina sunflower oils and their biodiesels in a DI engine for 200 hours to test engine longevity, emissions and performance. Funded by the Governor's Energy Office Supercluster Clean Energy Grant.
Biodiesel Pollution Formation Kinetics

NOx emissions from biodiesel powered engines increase compared to pure petroleum diesel which threatens widespread acceptance of biodiesel. This project will increase our understanding of methyl ester fuel chemistry and its role in NOx production in CI engines. Sponsored by the National Science Foundation.
Enhanced Homogenous Charge Compression Ignition (HCCI) Engine Performance

Homogeneous charge compression ignition (HCCI) engines have the potential to produce the high fuel economy of a compression ignition (CI) engine, with the low emissions of a spark ignition (SI) engine. Recent research suggests that the ideal HCCI fuel can be realized with current bio-derived alcohols. This research will examine the characteristics of such alcohols in order to find an ideal HCCI fuel.
Emissions from Algae-Derived Biodiesel

There are many variables to take into account when choosing an algae strain for biofuel development, generally biofuels reduce PM, CO and HC emissions but NOx increases. Through tests on a John Deere 4024t, we hope to characterize emissions from different algae strains to determine the best candidate that will reduce emissions most favorably.
Ignition and Combustion of Bio Methyl Ester Fuel Droplets

The complete mechanism behind the NOx increase from biodiesel is not completely understood, but evidence suggests that it is caused by differences in both the physical properties and the chemical oxidation mechanisms of biodiesel and petroleum diesel. By examining methyl ester droplet ignition, we hope to characterize the chemical kinetic mechanisms behind biodiesel NOx and PM processes.
