VORTEX CONTROLLED MULTIFUEL COMBUSTION.
Abstract
An investigation was undertaken to determine the effect vortex-type flow has on the multifuel operation of a 3.5in. bore x 4.5in. stroke, two-stroke cycle, loop scavenged, air cooled high-speed compression-ignition engine. The open-type, Lanz-type and Ricardo-type chambers were investigated but the most effective results were obtained with a vortex combustion chamber concentric to the cylinder axis and separated from the cylinder by a plate having swirl producing passages around its periphery and a protruding central throat which the piston engaged near TDC. This chamber operated smoothly, effeciently and at high specific output on a number of fuels at a compression ratio of 25:1 without the necessity of intake air throttling at light load. High-speed photographs were taken of the combustion process within this chamber after it had been modified and fitted with a quartz window. The combustion photographs along with the engine test results provided a means by which the flow pattern and combustion process could be analyzed. (Author)
