  "textContent": "An internal combustion engine with an external circulation system and a working method thereof are provided. The internal combustion engine is externally connected to the external circulation system through an intake port and an exhaust port. The external circulation system is capable of operating in a circulating manner when the internal combustion engine is not running, a significant raise in intake temperature is achieved during intake heating or exhaust heating, thereby the cold start-up performance of the internal combustion engine is improved and harmful emissions during cold start-up is reduced, and a compression ignition working mode of a low compression ratio engine is facilitated to be achieved.",
