Summary:

A new combustion chamber design is proposed in which it is possible to control the scale and intensity of turbulence generated just prior to ignition. A single cylinder engine has been fitted with the new chamber, and measurements of the turbulence field with a hot-wire anemometer are presented. The chamber design has been compared to a conventional bowl-in-piston design under both motoring and fired operation. Hotwire measurements showed an increase in turbulence intensity of 50% and a reduction in the length scale of turbulence compared to the conventional chamber. Cylinder pressure measurements indicated that the mass-burn rate is increased with the new chamber, particularly during the early stage of combustion. During operation at 1140 rpm with the new chamber, peak cylinder pressure was 4% higher and occurred 3° earlier than for the conventional chamber
