ABSTRACT:
A reciprocating internal combustion engine includes a variable compression ratio system for adjusting the compression ratio of an engine in a first compression range located about a first predetermined compression ratio in the event that the engine is operating at a first predetermined load range, with the variable compression ratio adding a fixed clearance volume to the volume of the combustion chamber in the event that the engine is operating in a knocking condition beyond the range of the first compression range.
