PIV Measurements of In-cylinder Flow and Correlation with Engine Performance

Motivation. Early research on spark-ignited engines in passenger cars
demonstrated that combustion is slow when the fuel/air mixture is introduced into
the engine cylinder in a quiescent manner without large-scale fluid motion and
turbulence generation [1]. Thus, modem internal combustion engines are
designed to promote turbulent combustion in the engine cylinder through
enhanced in-cylinder flow Fields. The details of the in-cylinder flow fields have
important effects on the ...
