摘要： PROBLEM TO BE SOLVED: To detect a foreign matter such as a deposit deposited on a cylinder internal pressure sensor, with a simple constitution, to efficiently remove the foreign matter.SOLUTION: An ECU 60 generates vibration by an inverse piezoelectric effect by applying a voltage on a piezoelectric element of the cylinder internal pressure sensor 48, and acquires a vibration frequency Vb, and detects a foreign matter such as a deposit deposited on the cylinder internal pressure sensor 48 based on a deviation between the acquired vibration frequency Vb and a reference vibration frequency Va generated when the foreign matter is not deposited on the cylinder internal pressure sensor 48. Since no special structure or sensor is required for detecting deposition of the foreign matter, the system can be simplified. The foreign matter is removed only when detected, so that there is no need to unnecessarily execute control for removing the foreign matter, thereby reducing wasteful energy loss.

摘要： PROBLEM TO BE SOLVED: To determine a failure in a cylinder internal pressure sensor accurately over a wide operating region even without preparing a lot of data.SOLUTION: An ECU 50 calculates a corrected output value Pfixby correcting an offset component from a sensor output value αPon the basis of a reference output value αPof the cylinder internal pressure acquired during suction stroke and a suction pressure Pim during the suction stroke. The heat generation amount parameters Qand Qat two target crank angles θ1 and θ2 during compression stroke are calculated on the basis of the corrected output value Pfix, while abnormal output sensitivity of the cylinder internal pressure sensor 44 is detected on the basis of the gradient K of the heat generation amount parameter Q. The amount of data, adapted man-hours, etc. required to determine a failure, are reduced. Additionally, a failure is determined without using the integral value, maximum value, etc. of the cylinder internal pressure which are likely to cause variation in combustion, so that the margin of the criterion for determining a failure can be minimized.

摘要： PROBLEM TO BE SOLVED: To accurately and stably detect variation of an air-fuel ratio between cylinders without being affected by detecting environment of the individual cylinder. SOLUTION: An ECU 60 calculates a combustion proportion MFB of the respective cylinders based on cylinder pressures and calculates the maximum change rate CS of the combustion proportion in a condition that the respective cylinders are equalized in ignition timing under ignition timing uniforming control. The ECU further calculates the maximum change rate CS one of the specific cylinder which is most different in maximum change rate CS from the other cylinders among all cylinders, and an average maximum change rate CS ave which averages the maximum change rates CS of the other cylinders. When a parameter K, which is a ratio (CS one /CS ave ) of them, is larger than a predetermined threshold value α, A/F imbalance is determined to be abnormal. With this, even when there is variation in detection sensitivity and detection environment of sensors between the cylinders, the A/F imbalance can be determined accurately.
