Cylinder-head surface temperature and maximum pressure in a diesel engine


"This report presents the result of an experimental investigation on the effect of 1) fuel consumption in a diesel engine on the mean cylinder-head surface temperature 2) engine speed and load on the maximum cylinder pressure. A fast-response thermocouple was fixed in the cylinder head and temperatures were measured for various load and speed conditions. An attempt was made to record a transient surface temperature versus crank-angle diagram. Some doubt as to the reliability of this recording may arise because of the very small amount of time lag in the thermocouple action. This is immaterial to the subject of this investigation since we are dealing here with mean temperature only. A pressure transducer was used to measure cylinder pressure. Signals from this pressure transducer and crank-angle signals from a magnetic pickup were transmitted to an oscilloscope and the recording of the pressure versus crank-angle diagram was obtained by means of a drum camera. Maximum pressure and crank angle at maximum pressure were measured for various load and speed conditions"--Abstract, page ii.
