Abstract

Pistons inside spark-ignition internal combustion engines compress air-fuel mixtures which are ignited by an electrical spark. The combustion gases expand and push back against the piston generating useful mechanical work. Higher compression results in greater reaction efficiency but also higher temperatures. If the temperature exceeds the autoignition temperature of the mixture, premature ignition generates a force that works against the piston cycle, reduces overall power, causes overheating, and produces an audible knocking sound. Any given fuel-engine combination has an upper limit to the compression ratio that can be used without knock. Compression-ignition engines (those without spark plugs) manifest the same tendency.
