| description | The utility model provides an EGR system and a control device of the EGR-cooled air inlet temperature. Control over the EGR-cooled air inlet temperature is achieved. The control device comprises a first bypass pipe, a second bypass pipe and a temperature controller connected with the first bypass pipe and the second bypass pipe, the temperature controller is controlled by the EGR-cooled air inlet temperature, the first bypass pipe is connected with an EGR cooler in parallel, and the second bypass pipe is connected with a first main pipe in parallel. Only when the EGR-cooled air inlet temperature is too low, the temperature controller controls the first bypass pipe to be communicated; only when the EGR-cooled air inlet temperature is too high, the temperature controller controls the second bypass pipe to be disconnected. According to the EGR system and the control device, the problems of gumming and sulfate generation of the EGR cooler when the EGR-cooled air inlet temperature is too low are solved, the reliability of the cooler is improved, the service life of the cooler is prolonged, and the failure rate of a diesel engine is decreased. |
