Meanwhile, the problem of the icing of the crank is avoided in the development of each engine; in the traditional design, the arrangement that a curved pipeline is prevented from facing the wind is generally adopted; a heat-insulating sheath is added outside the curved pipeline; a heating system is added in the curved pipeline, etc.

In the method, the problem of the icing of the triton can be effectively solved by adding the heating system, and a plurality of vehicles adopt the method at present, but the cost is higher. Other methods only improve the icing of the triton and cannot fundamentally solve the problem of the icing of a crankcase ventilation system.
