Measuring of In-cylinder Pressure of Diesel Engine during Cranking Period under Low-Temperature Condition
Measuring of in-cylinder pressure of diesel engine during cranking period under low-temperature condition was attempted by using a strain gauge. Variation of dynamic strain of glow plug associated with the in-cylinder pressure was obtained by means of a strain gauge attached to the glow plug housing. In order to convert the dynamic strain to pressure, relationship of in-cylinder pressure to dynamic strain was investigated by using a piezoelectric pressure sensor. Calibration coefficient, which converts dynamic strain to pressure, was derived from the values of dynamic strain and in-cylinder pressure at the compression end in a motoring operation. As the result, in-cylinder pressure of diesel engine during cranking period can be obtained, and rate of heat release can be derived from the obtained in-cylinder pressure. Both the in-cylinder pressure and the rate of heat release reveal that ignition of fuel spray of each cycle was remarkably unstable during the cranking period under the low-temperature condition.
