The combustion lab, housed at the Alternative Energy Research Building, is home to a 1.1 L optically accessible constant volume combustion chamber. Using this combustion chamber, studies can be conducted on spark plug ignition; diesel fuel injection; alternative fuel ignition, combustion, spray and emissions; and interaction of spray jets with pulsed injections. Data can also be analyzed to characterize droplet, spray, vaporization and soot using optical and laser based diagnostics.
