This paper presents the results of a study of the air motion in a motored four-stroke direct injection diesel engine using hot-wire anemometry. The effects of engine speed, valve masking and supercharging on mean air swirl have been studied. A theoretical analysis is developed for the mean air swirl which in general shows good agreement with the experiments reported here and with the measurements of other workers on similarly sized engines. The problem of ‘squish’ has been investigated and it is shown to be the radial component of the spiralling swirl flow entering the combustion chamber. Reasonable agreement has been found between measurement of the radial flow component at the edge of the combustion bowl and a theoretical analysis that considers the bulk radial flow of air to the combustion bowl during the last 30°-40° b.t.d.c. of the compression period.

Theory And Experiment

Theoretical analysis and measurements of air velocities in cylindrical prechambers of the indirect injection type Diesel engine are reported. Comparisons are made between the theoretical analysis and the measurements for two cylindrical prechambers tested in the present study and the results of previous investigators [4–6], A correlation is derived-to link air velocity in the cylindrical prechamber and known engine parameters. The results show that there is poor and inconsistent agreement between theory and experiment in some of the cases considered. Reasons are suggested to explain these inconsistencies. The derived correlation could serve as an additional tool for the engine designer in predicting air motion and hence combustion and heat transfer in the prechamber of indirect injection diesel engine.
