- Summary:
- The object of this report is to present the results of tests to determine the effect on engine performance of directing the flow of the inlet air to a 5-inch by 7-inch single cylinder, solid injection, compression ignition engine. After a few preliminary tests, comparative runs were made at a speed of 1500 R.P.M. with and without directed air flow. It was found that directing the flow of the inlet air toward the fuel injection valve gave steadier engine operation, and an appreciable increase in power, and decreased fuel consumption. The results indicate the possibility of improving the performance of a given tye of combustion chamber without changing its shape and with no change in valve timing. They would also seem to prove that directional turbulence, set up before the inlet valve of a four-stroke cycle engine, continues in the engine cylinder throughout the compression stroke.
