ABSTRACT:
An exhaust gas recirculation distribution variation sensing device has a torque sensing section that senses instantaneous torque caused with combustion of fuel injected from an injector for each cylinder, an injection quantity sensing section that senses an actual injection quantity of the injected fuel for each cylinder, and an exhaust gas recirculation distribution variation calculating section that calculates an exhaust gas recirculation distribution variation as a distribution variation of recirculated exhaust gas to respective cylinders based on a variation in the torque sensing value of the torque sensing section among the cylinders (i.e., a torque variation) and a variation in the injection quantity sensing value of the injection quantity sensing section among the cylinders (i.e., an injection quantity variation).
