An internal combustion engine, in which intake air flows through an intake passage into a combustion chamber and exhaust gas resulting from the combustion in the combustion chamber flows through an exhaust passage, includes an exhaust gas purifier provided...

In a compression self-igniting internal combustion engine, in the case of using the oxygen concentration in a cylinder and the pre-ignition pressure in the cylinder before fuel injection as parameters for a gas state in the cylinder before fuel injection a...

An object of the present invention is to restrain a deterioration of emission even if the actual control condition including the required torque is different from the set control condition. An ECU (5) establishes a control amount of an EGR valve (42) in su...

The method involves regulating the exhaust gas feedback rate and/or the fuel feed to the engine (10) and/or the fresh air quantity depending on a detected actual induction pipe pressure so that the actual pressure set in the induction pipe (22) equals a de...
