Abstract

There are several promising biofuel candidates for automotive applications that reduce greenhouse gases, improve air quality, and reduce the dependence on foreign oil. Currently, gasoline fuel properties such as octane number, pressure and temperature sensitivities limit the operating range of reciprocating engines. Because of those limitations, and the need to operate at a higher load to increase engine efficiencies, advanced fuels must be used. Cyclopentanone (C5H8O) is among one of the biofuel candidates considered for t U.S. Department of Energy's Co-Optimization of Fuels and Engines (Co-Optima). In this study, laminar burning velocity (LBV) of cyclopentanone was measured in a spherical combustion chamber at initial conditions of 408 K, and atmospheric pressure for various equivalent ratios (φ) from 0.7 to 1.4. LBV is defined as the velocity at which unburned gases moves in the normal direction to the combustion wave surface. This is a crucial property in spark ignition engines because it affects the combustion duration. High-speed schlieren photography method was used to capture the flame propagation events. The flame stability was assessed based on Markstein length, and both linear and nonlinear extrapolation methods were utilized and compared.
