Water outlet pipe assembly of engine

Abstract

The invention discloses a water outlet pipe assembly of an engine. The water outlet pipe assembly comprises a large circulating pipe and a small circulating pipe which can be used as a warm air water return pipe; and the inlet end of the large circulating pipe and the inlet end of the small circulating pipe are connected to a public flange and are connected with an engine cylinder block by the public flange. The large circulating pipe, the small circulating pipe and the warm air water return pipe in an engine cooling circulation system can be integrated to form the integrated water outlet pipe assembly of the engine, so that the amount of special parts of the engine is reduced, meanwhile, a cooling loop is enabled to be simpler, the cost is lower, and the water leakage probability of a cooling system is reduced.

Description

technical field [0001] The invention relates to the field of engine components, in particular to an engine water outlet pipe assembly. Background technique [0002] The water outlet pipe is an important component of the engine cooling system. The water outlet pipe in the existing engine usually includes a large circulation pipe, a small circulation pipe and a warm air return pipe. Circulation pipe or small circulation pipe, the warm air return pipe is used to transport the cooling water flowing out of the warm air heat exchanger to the water channel of the cylinder body. In the traditional engine cooling cycle, the large circulation pipe, small circulation pipe and warm air return pipe are The cooling pipes are independent of each other, and the cooling pipes need to be connected with rubber hoses, the cooling circuit is complicated and the chance of water leakage is high. [0003] Therefore, there is a need for an engine outlet pipe assembly that integrates the large circu...
