るデイーゼルエンジンの排気微粒子浄化装置。[Claim for Utility Model Registration] A trap provided with an electric heater in the exhaust passage of a diesel engine, and a bypass passage provided with a throttle valve to bypass the trap,
The exhaust particulate purification device for a diesel engine that opens the throttle valve and ignites and burns particulate in the exhaust gas using the electric heater includes a temperature sensor that measures the temperature of the exhaust gas flowing into the trap, and a temperature sensor that measures the temperature of the exhaust gas flowing into the trap; When gas temperature information is input and trap regeneration is completed, if it is detected that the temperature of the exhaust gas flowing into the trap is below a preset temperature, the bypass valve is controlled to be held open until a predetermined period of time has elapsed. An exhaust particulate purification device for a diesel engine, characterized in that it is equipped with a computer that performs the following steps.
