。 An additive mixing device is installed in the fuel supply path from the fuel tank to the fuel injection pump, which mixes additives into the fuel to create additive-containing fuel and controls the supply of the additive-containing fuel with a solenoid valve. A fuel return path is provided between an injection pump and an injection nozzle and a fuel tank to collect excess additive-containing fuel from the fuel injection pump and injection nozzle and return the additive-containing fuel. Addition to a diesel engine, characterized in that the supply device includes a smoke sensor provided in the exhaust pipe, and a smoke control device that controls the amount of opening and closing of the electromagnetic valve according to the smoke concentration detected by the smoke sensor. Supply device for fuel containing chemical agent.
