PURPOSE:To obtain angle reference data with high accuracy by providing the titled device with an analog/digital converter or the like to which signals from a rotation detector detecting the rotating speed of an engine and a pressure gauge detecting the inner pressure of a cylinder of the engine are inputted. CONSTITUTION:The cylinder inner pressure inputting device is provided with an engine rotating system 1, a cylinder 2, the rotation detector 3, a pressure gauge 4, the A/D converter 5, etc. An operator 6 calculates the time interval corresponding to the angle of rotation from a signal of the rotation detector 3 and the signal of the rotation detector 3 and a signal from the cylinder inner pressure gauge 4 are inputted to the operator 6 through the A/D converter 5. In said constitution, the angle reference data with high accuracy can be obtained by inputting the rotation reference signal and the cylinder inner pressure simultaneously as data and then rearranging these data as data having 1 deg. intervals even if the rotating speed is changed. |
