RESEARCH REVIEW

Biofuels, Engines continued from page 7

Engine Evaluation

Mechanical engineers are running state-of-the-art, electronically controlled engines fueled with new biofuels to measure performance, emissions and efficiency. Their work includes:

4 Conducting engine dynamometer tests to validate the

model predictions of combustion characteristics, and measure gaseous emissions and fuel conversion efficiency,

4 Applying computational fluid dynamics models with

detailed chemical kinetics to simulate complex combustion and emissions processes, and

4 Using visualization tools to conduct in situ analysis of combustion characteristics.

Argonne mechanical engineer Doug Longman uses a volt meter to check the electronic system on a modern diesel engine. The research team will use Argonne’s engine testing facilities to measure the performance and emissions of newly developed biofuels.

Life Cycle Analysis and Process Economics

Environmental system analysts are tracing the environmental impact of various fuel and engine combinations using Argonne’s GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) modeling software. This work includes:

4 Calculating the total energy consumption of new fuel/ engine scenarios,

4 Determining greenhouse gas emissions and other criteria pollutants,

4 Comparing the environmental impacts of fuels and engines on a full life cycle basis,

4 Considering the implications on water use, water quality, land use and co-product production, and

4 Developing models for the cost of commercial-scale fuel production.

Funding

Funding for this project was provided by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Biomass and Vehicle Technologies Programs, and the Office of Science, Basic Energy Sciences Program.
