Description

A water outlet pipe structure and an engine

technical field

The invention relates to the technical field of engine components, in particular to a water outlet pipe structure and an engine.

Background technique

The engine water outlet pipe is a component that connects the engine water outlet hole and the water tank. In some engines, due to the height requirement of the fan, the fan needs to be connected to the water pump. Therefore, the water pump needs to be raised to the same height as the cylinder head. The water outlet of the cylinder head is connected to the water outlet pipe, so the water pump and the water outlet pipe will interfere. . The practice at this stage is usually to raise the water outlet pipe and bend it upwards to avoid the water pump. However, this solution makes the cross-sectional area of the water flow insufficient, causing the water outlet flow rate to exceed the limit. In order to ensure sufficient cross-sectional area for water flow, the water pump needs to be extended toward the front end. However, if the cantilever of the water pump is too large, the risk of failure will increase, and the height of the whole machine will also be high.
