Summary:

The paper describes a water analogy rig and its associated instrumentation and data acquisition system, developed to make particle image velocimetry (PIV) measurements of in-cylinder flow during the intake stroke. Methods of producing parameters to describe the flow characteristics of four valve engines with tumbling air motion are evaluated and correlation with combustion performance is examined for two different engines with a total of seven different inlet port designs. Each inlet port configuration was also evaluated by conventional steady flow methods. The results show that the dynamic water flow rig gave improved correlation with combustion data than that obtained with conventional steady flow methods of characterising in-cylinder flow patterns
