1. A controlling apparatus of a diesel engine for decreasing the detrimental compositions of exhaust gas by supplying an appropriate amount of oxygen for fuel burning comprising:

  • a recirculating pipe, having a recirculated gas temperature sensor and a recirculated gas throttle valve, for recirculating exhaust gas between exhaust system and intake system;

    an intake pipe having an outside air temperature sensor and an outside air throttle valve;

    a fuel sensor;

    an engine state sensor;

    an air calculating section for calculating a required amount of air on the basis of an amount of fuel detected by said fuel sensor and the outside air temperature detected by said outside air temperature sensor,an outside air introduction control section for operating said outside air throttle valve responding to the calculated required amount of air;

    a recirculated gas calculating section for receiving information of the calculated required amount of air and for calculating a required recirculated gas flow rate on the basis of information from said recirculated gas temperature sensor and said engine state sensor; and

    a recirculating gas control section for operating said recirculated gas throttle valve responding to the calculated amount of recirculated gas.
