A study was performed to analyze the instability associated with the breakdown of tumble during compression of an internal combustion engine flow. The POD was used to identify the instability and breakdown of tumble during compression. Two different POD methods were used. It was observed that the tumble vortex becomes unstable during compression and ultimately leads to turbulence near the end of compression. This turbulence leads directly to better engine performance and the possible use of leaner fuel mixtures via faster burning rates.
