A combustion control device for an engine, comprising: a plurality of cylinders; a surge tank disposed in an intake path to the cylinders; an independent intake passage connecting the surge tank and an intake port of each of the cylinders; a fuel injection valve that is disposed for each of the cylinders and that supplies fuel into each of the cylinders; and a control unit that controls a fuel injection amount of each of the fuel injection valves according to an engine operating state, wherein the control unit corrects a target fuel injection amount of each of the cylinders, the target fuel injection amount being determined according to the engine operating state, based on a re-intake correction amount set in each of the cylinders according to a re-intake amount of intake air from the intake port in internal EGR in each of the cylinders, the engine includes an intake valve that opens and closes an intake port of each of the cylinders and an exhaust valve that opens and closes an exhaust port of each of the cylinders, the internal EGR is achieved by setting a valve overlap in which both the intake valve and the exhaust valve are open, the independent intake passage is set to have a length that allows intake air (g11, g12, g13, g14) blown out from the intake port to reach the surge tank during a period of the valve overlap, the engine is a four-cylinder engine in which four cylinders are arranged in a line, the independent intake passages are arranged in a line in a direction in which the cylinders are arranged, and the surge tank includes a flow path space that is long in a direction in which the cylinders are arranged, and the surge tank is connected to an upstream intake path that introduces intake air to a central area of the surge tank in a longitudinal direction, wherein the control unit corrects the target fuel injection amount so that among the four cylinders arranged in a line, air-fuel ratios of end-side cylinders (#1, #4) located at both ends are on a lean side and air-fuel ratios of two center-side cylinders (#2, #3) sandwiched between the end-side cylinders are on a rich side. a plurality of cylinders; a surge tank disposed in an intake path to the cylinders; an independent intake passage connecting the surge tank and an intake port of each of the cylinders; a fuel injection valve that is disposed for each of the cylinders and that supplies fuel into each of the cylinders; and a control unit that controls a fuel injection amount of each of the fuel injection valves according to an engine operating state, wherein the control unit corrects a target fuel injection amount of each of the cylinders, the target fuel injection amount being determined according to the engine operating state, based on a re-intake correction amount set in each of the cylinders according to a re-intake amount of intake air from the intake port in internal EGR in each of the cylinders, the engine includes an intake valve that opens and closes an intake port of each of the cylinders and an exhaust valve that opens and closes an exhaust port of each of the cylinders, the internal EGR is achieved by setting a valve overlap in which both the intake valve and the exhaust valve are open, the independent intake passage is set to have a length that allows intake air (g11, g12, g13, g14) blown out from the intake port to reach the surge tank during a period of the valve overlap, the engine is a four-cylinder engine in which four cylinders are arranged in a line, the independent intake passages are arranged in a line in a direction in which the cylinders are arranged, and the surge tank includes a flow path space that is long in a direction in which the cylinders are arranged, and the surge tank is connected to an upstream intake path that introduces intake air to a central area of the surge tank in a longitudinal direction, wherein the control unit corrects the target fuel injection amount so that among the four cylinders arranged in a line, air-fuel ratios of end-side cylinders (#1, #4) located at both ends are on a lean side and air-fuel ratios of two center-side cylinders (#2, #3) sandwiched between the end-side cylinders are on a rich side.
