The invention relates to the technical field of hybrid vehicles, and discloses a hybrid vehicle engine which comprises a box body, wherein a cylinder body is fixedly connected to the middle of the topside of an inner cavity of the box body; and an extrusion cylinder is movably sleeved with the cylinder body. According to the hybrid vehicle engine, a liquid release box, a direction-changing cooling pipe, a liquid outlet water control device and a holding box cooperate with each other, so that cooling water can conveniently flow into the direction-changing cooling pipe from the liquid release box by virtue of the height difference between the liquid release box and the holding box; and then the direction-changing cooling pipe is utilized to surround the inner side of the cylinder body so asto facilitate the cooling of the interior of the cylinder body. When the direction-changing cooling pipe absorbs the temperature of the inner side of the cylinder body, a protective water filtering plate arranged inside a liquid outlet pipe fixedly connected to the bottom of the direction-changing cooling pipe is heated to expand, and then telescopic plates are driven to move to the two sides, sothat continuous heat dissipation of the interior of the cylinder body is facilitated. The good continuous cooling effect of the hybrid vehicle engine is improved, and at the same time, the cost for heat dissipation is effectively reduced.

    本发明涉及混合动力汽车技术领域,且公开了一种混合动力汽车发动机,包括箱体,所述箱体内腔顶侧的中部固定连接有筒体,所述筒体的内部活动套接有挤压筒。该混合动力汽车发动机,通过液体释放箱、换向降温管、出液控水装置和盛放箱之间的配合,利用液体释放箱与盛放箱之间的高度差,便于液体释放箱向换向降温管的内部流入冷却水,继而利用换向降温管对筒体的内侧进行环绕,便于对筒体的内部进行降温,当换向降温管将筒体内侧的温度吸收后,这时与换向降温管底部固定连接的出液管内部的防护滤水板受热膨胀,继而带动伸缩板向两侧移动,便于对筒体的内部进行持续散热,提高混合动力汽车发动机良好持续降温效果,同时有效降低散热所需成本。
