The Effect of High Temperature of the Cylinder Head on the Knocking Tendency of an Air-Cooled Engine Cylinder

One of 533 reports in the series: NACA Advanced Restricted Reports available on this site.

PDF Version Also Available for Download.

Description

Report presenting the results of tests to determine the extent to which the knocking tendency of an air-cooled engine cylinder is increased when the cylinder head is poorly cooled and when the cylinder temperature exceeds the maximum specified by the engine manufacturer. The tests showed that, when the cylinder-head temperature was increase from 400 to 600 degrees Fahrenheit, the knock-limited indicated mean effective pressure was reduced 3 percent at a fuel-air ratio of 0.097 and 39 percent at a fuel-air ratio of 0.065.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
