Problems solved by technology
[0003] At present, the structure and function of the water intake pipe of the engine cylinder head is single. With the continuous improvement of the reliability and performance requirements of the engine, the requirements of the engine thermal management system are also continuously improved. In order to meet the requirements of the National VI emission regulations, the engine emission technology route adds the EGR system. The layout of the engine and the complexity of parts design have increased, so the single structure and function design of the water inlet connection has been difficult to meet the needs of the National VI engine research and development and the market

The invention discloses a multifunctional water inlet connecting pipe for a diesel engine. The multifunctional water inlet connecting pipe for a diesel engine includes: a first branch flow channel, one end of which has a first water outlet interface, and the other end is a first water inlet interface; a second branch flow channel, one end of which has a second water outlet interface, and the other end is a The second water inlet; the main water inlet, one end of which is connected to the first water inlet and the second water inlet of the first branch flow channel, and the other end of the water inlet is the water inlet; the EGR cooler bracket, It is a rectangular structure, arranged on the top of one end of the first branch flow channel and the second branch flow channel, and has a plurality of threaded holes; and a plurality of water intake joints. The multi-functional water inlet pipe for diesel engine integrates the design of the EGR cooler support function, which can effectively ensure the cooling water flow of the engine and ensure the support and fixation of the EGR cooler. reliability.
Description
technical field [0001] The invention relates to the field of engines, in particular to a multifunctional water inlet connector for diesel engines. Background technique [0002] The water intake connection is one of the key components for the engine to circulate the coolant into the engine cylinder head to achieve the overall thermal balance of the engine. With the upgrading of the national environmental protection emission regulations, the engine emission route has added the EGR system, and the arrangement and fixing of the EGR cooler on the whole machine have an important impact on the engine EGR system and the overall reliability and performance of the engine. [0003] At present, the structure and function of the water intake pipe of the engine cylinder head is single. With the continuous improvement of the reliability and performance requirements of the engine, the requirements of the engine thermal management system are also continuously improved. In order to meet the r...
