Abstract

The invention belongs to the technical field of vehicles, and particularly relates to an engine circulating waterway system and a bubble removing method. The bubble removing method comprises the steps of judging the operation state of an engine; detecting whether bubbles exist in an exhaust pipe of the engine or not according to the working state of the engine; controlling the engine to enter an internal circulation mode according to the fact that no bubble exists in the exhaust pipe; and controlling the engine to enter an exhaust mode according to the fact that bubbles exist in the exhaust pipe. According to the bubble removing method for the engine circulating waterway system, whether bubbles exist in cooling liquid or not can be effectively monitored in real time by adding control logic for bubble real-time monitoring, and it is achieved that the engine automatically enter an exhaust mode or an internal circulation mode; and the cooling liquid discharged by the engine exhaust pipe is controlled to enter different circulation modes, heat dissipation is reduced, and temperature rise of the cooling liquid in the engine in low-temperature seasons is facilitated.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to an engine circulation waterway system and a method for removing air bubbles. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] During the normal operation of the engine, the exhaust pipe of the engine cooling system will continue to circulate the coolant, and the coolant will flow to the expansion tank through the exhaust pipe to ensure that the air bubbles generated during the operation of the engine cooling system pipeline can be discharged to avoid damage caused by air bubbles. Accumulation of local high temperature caused by poor water circulation will cause engine failure caused by high temperature. [0004] In the prior art, the local high temperature of the waterway is avoided by timing the exhaust, but it will cause the problem of engine failure before ...
