<p>A combustion chamber (10) for reciprocating internal combustion engines greatly reduces large quench areas in the combustion chamber (10), and substantially matches the combustion chamber periphery with the upper edge circumference of the mating cylinder wall, to reduce greatly or substantially eliminate narrow quench areas of relatively high surface area to volume ratios. This increases the average combustion temperature due to the reduction of surface area relative to the volume of the combustion chamber (10), thereby producing more efficient combustion resulting in a reduction in unburned hydrocarbons during the combustion portion of the cycle. The removal of material to eliminate such large quench areas also slightly enlarges the combustion chamber (10) to reduce the compression ratio, thus reducing the production of oxides of nitrogen during combustion. The combustion chamber (10) is also radiused and smoothed internally, to eliminate rough and sharp edges which may lead to preignition and detonation.</p> |
