  In the transportation fuel matrix for the United States biofuels, alternative, and renewable fuels hold a prominent position in the future. Due to concerns of energy independence, national security, and greenhouse gas emissions, and resource depletion, several novel engine technologies are being evaluated to reduce emissions and reduce fuel consumption. Of these technologies, low temperature combustion engines offer significant promise with extremely high efficiency along with concurrent low-emissions.
The talk will cover the current research activities at the Alternative Fuels Combustion Laboratory (AFCL) in MTU. The AFCL houses the optically accessible combustion vessel (CV) which was funded by NSF through a Major Research Instrument development program and has been successfully operating since 2009. The main objective of utilizing the facility (Pmax = 350 bar and Tmax = 2000 K) is to characterize combustion processes representative of advanced engine operating conditions. This unique CV facility is used to study for high-pressure spray dynamics of biofuels, and alternative fuels, spark ignition engine fundamentals, emissions/soot formation, and develop necessary laser diagnostics to characterize fundamental spray and combustion processes.
The talk will present recent results from diesel spray combustion including soot formation and spray modeling, gasoline direct injection (GDI) to characterize the fuel-dependent vaporizing process, and flame kernel development by spark ignition under turbulence. Additionally recent development of non-intrusive diagnostic techniques along with relevant images will be demonstrated.
