Influence Of Top Ring End Gap Types At Blow-By Of Internal Combustion Engines 931669

The gas that flows from the combustion chamber to crankcase of internal combustion engines (“Blow-By”) and the reverse flow (“Blow-Back”) have detrimental effects in the engine power, pollutant emissions and lubricant degradation.
A main factor to control this flow is the first piston ring gap. The influence of the area defined by the gap, specially of the chamfer at end gap, is analyzed by computer simulation and dynamometer tests.
An unusual type of piston ring contact face coating at end gap, allows a reduction of up to 50% in the ring gap area and engine Blow-By.
