Several techniques have been presented in the literature for measuring mixture temperatures in internal combustion engines during the compression process up to the time of knock. This paper describes a new method based on the light-absorbing properties of benzene vapor and presents engine data based on this technique.
The ultraviolet light absorption coefficient of benzene vapor has been measured over a temperature range of 300-1400 K (80-2060 F). This absorption coefficient, which is very sensitive to temperature, is a function of temperature to the eighth power at room temperatures and decreases smoothly to a fourth power function at approximately 1000 K (1340 F).
The extreme sensitivity of the absorption coefficient to temperature allows precise determination of gas temperatures during the early part of the compression process in a Cooperative Fuel Research (CFR) engine and throughout compression of the fuel/air mixture. The data quantitatively support an analytical prediction that heat transfer from the chamber wall to the inlet mixture, during the intake stroke, causes increased compression temperature histories.
