description PROBLEM TO BE SOLVED: To provide an engine capable of quickly detecting the fact, even if the data of intake pressure and the data of exhaust pressure are conversely inputted in an ECU.SOLUTION: An engine 100 is equipped with an intake take-out pipe 51, an exhaust take-out pipe 54, an intake/exhaust pressure sensor 53, and an ECU 50. The intake take-out pipe 51 takes out gas flowing in an intake system. The exhaust take-out pipe 54 takes out gas flowing in an exhaust system. The intake/exhaust pressure sensor 53 obtains intake pressure by detecting the pressure of the gas taken out by the intake take-out pipe 51, and obtains exhaust pressure by detecting the pressure of the gas taken out by the exhaust take-out pipe 54. The ECU 50 determines whether the data of the intake pressure and the data of the exhaust pressure are conversely inputted or not, on the basis of difference between the pressure inputted as the intake pressure and the pressure inputted as the exhaust pressure, or an opening of an EGR valve 43 changed according to the difference. 【課題】吸気圧のデータと排気圧のデータが反対になってECUに入力された場合であっても、その事実を素早く検出できるエンジンを提供する。【解決手段】エンジン100は、吸気取出管51と、排気取出管54と、吸排気圧センサ53と、ECU50と、を備える。吸気取出管51は、吸気系を流れる気体を取り出す。排気取出管54は、排気系を流れる気体を取り出す。吸排気圧センサ53は、吸気取出管51によって取り出された気体の圧力を検出することで吸気圧を求めるとともに、排気取出管54によって取り出された気体の圧力を検出することで排気圧を求める。ECU50は、吸気圧として入力された圧力と排気圧として入力された圧力の差分、又は、当該差分に基づいて変化するEGRバルブ43の開度に基づいて、吸気圧のデータ及び排気圧のデータが反対になって入力されたか否かを判定する。【選択図】図2
