Experimental and numerical tools to investigate ringing in IC engines

Placeholder Show Content


According to the International Energy Agency, mitigating greenhouse gas emissions to limit global temperature increase to 2 degrees Celsius will require efficient, combustion-based systems for light-duty transportation to take the place of conventional spark-ignited gasoline engines in the next 25 years. One of the barriers to high-efficiency combustion strategies such as homogeneous charge compression ignition (HCCI) is a phenomenon known as ringing, the formation of damaging pressure waves in the engine during the combustion process. Previous experimental results indicate that disruption of ringing is possible, to achieve high efficiency and high power density. Two tools to obtain spatially-resolved information during the ringing combustion process are the primary contributions described in this dissertation. A quasi-1D reacting compressible flow model captures the essential physics of the ringing phenomenon, to target experimental investigation and to interpret experimental results. To obtain spatially-resolved experimental data, an optically accessible engine capable of 250 bar peak pressure and Schlieren imaging was designed, manufactured, and demonstrated.
