摘要：
The bulk temperature of the gas in a piston engine during combustion is determined by detecting the high frequency pressure oscillation in the combustion chamber operating the engine to produce knock and measuring the frequency of the lowest frequency mode of the high frequency knock signal. The frequency or inversely the period of that signal is a function of the gas temperature.
