摘要： This invention relates to an internal combustion engine and a control device for the internal combustion engine and has an object to provide an internal combustion engine and a control device therefore that can suppress occurrence of knocking if an EGR rate is increased. An EGR gas can be made to flow separately through one path via one EGR passage and an other path via another EGR passage. The EGR gas flow through the other path can be cooled by an intercooler. Since the intercooler usually has a capacity larger than that of an EGR cooler, its cooling capability is high, and the EGR gas can be made to flow into a surge tank in a state where heat of the EGR gas has been sufficiently emitted.

摘要： An object is to provide an abnormal combustion determining apparatus for an internal combustion engine that can identify a major factor causing an oil to flow into a cylinder. The abnormal combustion determining apparatus for the internal combustion engine that includes a plurality of cylinders detects, for each cylinder, a cylinder in which abnormal combustion has occurred. The cylinder in which the abnormal combustion has occurred, and a history of load applied during an operation are stored in memory. It is determined whether or not the cylinder in which the abnormal combustion has occurred and which is stored in memory, is a specific cylinder. It is determined whether or not load present in the history stored in memory and used prior to the occurrence of the abnormal combustion is higher than a threshold value. Based on a combination of a decision made by the cylinder determining means and a decision made by the load determining means, a major factor causing the oil to flow into the cylinder is identified from among relations established for factors of oil flowing into the cylinder according to the combination of these decisions made.

摘要： An individual exhaust passage is provided independently for each cylinder group in an internal combustion engine having a plurality of cylinder groups each having a plurality of cylinders. A first catalyst is provided in each of the individual exhaust passages. Downstream of those first catalysts, the individual exhaust passages merge to form a common exhaust passage in which a second catalyst is provided. When control of the internal combustion engine is switched from cylinder group-specific control to stoichiometric control, an air-fuel ratio control portion makes the air-fuel ratio of a cylinder group in which the air-fuel ratio was made rich by cylinder group-specific control lean for a predetermined period of time, and makes the air-fuel ratio of a cylinder group in which the air-fuel ratio was made lean by the cylinder group-specific control rich for a predetermined period of time.

摘要： A control apparatus for an internal combustion engine includes cylinder internal pressure sensors provided in each cylinder of an engine, and calculates a heat generation quantity in each cylinder based on the detected cylinder internal pressure and a crank angle. The control apparatus then obtains a combustion barycentric position, which is the crank angle at which a predetermined ratio of heat, of the total heat generation quantity in a combustion cycle, is generated. The control apparatus also calculates, based on the heat generation quantity, an actual starting point of combustion, which is a crank angle at which combustion actually started in the cylinder, and obtains the crank angle of the relative combustion barycentric position with respect to the actual starting point of combustion. When this crank angle exceeds an upper limit value, it is determined that combustion has truly deteriorated.
