摘要（英）：

The invention provides an engine water-cooling structure assembly, which comprises a water pump, wherein a water inlet pipe of the water pump is downward inclined opposite to the water level in the water inlet direction, and communicated with a water inlet of a pump chamber of the water pump; further, the inclined angle of the water inlet pipe of the water pump is larger than or equal to 15 degrees and is smaller than or equal to 45 degrees; and furthermore, the inclined angle of the water inlet pipe of the water pump is 23 degrees. The invention further provides an engine provided with the engine water-cooling structure assembly, and a motorcycle provided with the engine structure. The engine water-cooling structure assembly, the engine and the motorcycle have the advantages of high pump priming efficiency, high water pump starting speed and the like.
