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

Abstract

The invention discloses a multifunctional water inlet connecting pipe for a diesel engine. The multifunctional water inlet connecting pipe for the diesel engine comprises a first branch flow channel,a second branch flow channel, a water inlet header pipe, an EGR cooler support and multiple water taking joints; one end of the first branch flow channel is provided with a first water outlet connecting port, and the other end is a first water inlet connecting port; one end of the second branch flow channel is provided with a second water outlet connecting port, and the other end is a second waterinlet connecting port; one end of the water inlet header pipe is connected with the first water inlet connecting port of the first branch flow channel and the second water inlet connecting port, andthe other end of the water inlet header pipe is a water inlet; the EGR cooler support is of a rectangular structure, is arranged at the top of one end of the first branch flow channel and the top of one end of the second branch flow channel and comprises multiple threaded hole lugs. According to the multifunctional water inlet connecting pipe for the diesel engine, through integrated design of theEGR cooler support function, supporting and fixing of an EGR cooler can be guaranteed while the cooling water flow of the engine is guaranteed effectively, the engine can meet China 6 emission requirements, and meanwhile, the performance and the reliability of the engine are improved.

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...
