摘要： A control device of an internal combustion engine performs an air-fuel ratio feedback control to set an air-fuel ratio to a target air-fuel ratio, and determines abnormality of a fuel system based on a feedback correction amount by the air-fuel ratio feedback control. The control device of an internal combustion engine includes: a double tank type oil pan including: an inner tank and an outer tank for storing oil; and a mechanism which switches between connection and disconnection of the inner tank and the outer tank; and a controller configured to control the mechanism to connect the inner tank and the outer tank in a case where the feedback correction amount is equal to or larger than a first predetermined value. Thus, it is possible to prevent the air-fuel ratio from getting rich, and it is possible to appropriately prevent the erroneous determination of abnormality of the fuel system.

摘要： A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed in the top surface of a piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relatively small thickness. When the fuel injected in nearly the shape of a fan from the fuel injection valve is considered by being divided into a plurality of fuel segments in a radial direction, a side wall of the cavity has a first fuel deflection passage 82a and a second fuel deflection passage 82b for so deflecting at least two of the plurality of fuel segments as to pass near the spark plug. The side wall of the cavity is at least partly provided with a return portion 83 that protrudes toward the inside of the cavity. The first fuel deflection passage is not provided with the return portion 83 or is provided with the return portion having a short protrusion, and the second fuel deflection passage is provided with the return portion 83 having a long protrusion.

摘要： A control apparatus for an internal combustion engine is provided that can successfully achieve a desired acceleration by avoiding an absence of torque of the internal combustion engine due to an influence of EGR gas when the torque increases toward a required torque. A required throttle valve opening degree TAreq is set based on a required torque TQreq in accordance with a required throttle valve opening degree map that defines a relation between the required torque TQreq and the required throttle valve opening degree TAreq. In addition, a required EGR valve opening degree EGRreq is set based on a required load factor KLreq in accordance with a required EGR valve opening degree map that defines a relation between the required load factor KLreq and the required EGR valve opening degree EGRreq.

摘要： Cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors are disposed in each exhaust branch pipe connected to the cylinder groups, and a second air-fuel ratio sensor is disposed in a common exhaust pipe upstream from the catalyst. When a vapor amount introduced into an intake passage during purge control is determined, the vapor amount is determined during normal operation using output values from the first air-fuel ratio sensors and the vapor amount value learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor and the vapor amount value learned during rich-lean operation. Thereby, the vapor amount introduced into the intake passage when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined.
