Zusammenfassung:	To provide a signal processing device for an engine, capable of more properly correcting a cylinder pressure.SOLUTION: The signal processing device for the engine includes cylinder pressure detection means SN2 for detecting a cylinder pressure as a pressure in a cylinder 3, and intake pressure detection means SN6 for detecting an intake pressure as a pressure in an intake passage 30. Correction means 122 corrects the cylinder pressure detected by the cylinder pressure detection means SN2 on the basis of the intake pressure detected by the intake pressure detection means SN6 during a reference period set near an intake bottom dead center.SELECTED DRAWING: Figure 9 【課題】筒内圧をより適切に補正することができるエンジンの信号処理装置を提供する。【解決手段】気筒３内の圧力である筒内圧を検出する筒内圧検出手段ＳＮ２と、吸気通路３０内の圧力である吸気圧を検出する吸気圧検出手段ＳＮ６とを設ける。そして、補正手段１２２によって、吸気下死点付近に設定された基準期間中に前記吸気圧検出手段ＳＮ６により検出された吸気圧に基づいて、前記筒内圧検出手段ＳＮ２により検出された筒内圧を補正する。【選択図】図９
