Summary:

The thermodynamic analysis of swirlchamber engines presents aproblem that has not yet been satisfactorily resolved. One of themain reasons for this is the high level of accuracy required formeasuring the absolute pressures and pressure differences betweenthe cylinder and swirlchamber and the lack of adequate calculationmodels for heat transfer and the mass transfer between the twochambers.The paper describes, firstly, how the method of pressuremeasurement has been improved. Subsequently, the heat-releaseanalysis of Anisits and Zapf was used, however, this revealederrors in the heat transfer and mass flow rate. A new model forthese latter quantities is therefore proposed and has been deveopedusing motored pressure measurements.Results are presented which demonstrate how the method may beapplied to calculate the heat release rates in both chambers usingmeasurements from the fired engine and with variations in both loadand speed
