The purpose of this study is to establish a method to improve the accuracy of acquiring pressure trace of an internal combustion engine. Inaccuracy in acquiring pressure trace is caused by the thermal deformation of the diaphragm of a pressure transducer and the electric circuit characteristic of a charge amplifier. A correcting equation for inaccuracy caused by the thermal deformation was acquired by analyzing the deformation model of the diaphragm of the pressure transducer used in the experiment with a burner. As for the imaccuracy caused by the electric circuit characteristic of the charge amplifier, correcting equation was acquired by analyzing the simplified electric circuit of charge amplifier. By applying these equations, a method of improving the accuracy of pressure trace for four types of water-cooled pressure transducer was established.
