Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a methanol fuel heavy truck engine cooling and liquid buffer integrated water pipe. Background Art

[0002] A hydraulic retarder is also known as a hydraulic deceleration device. While exhaust braking can provide good braking when a car is going down a long slope, it is not very effective for heavy trucks with larger tonnage, and can also cause some damage to the engine. Currently, the traditional engine piping design for matching the hydraulic retarder uses separate pipes for both water inlet and outlet. The pipes from the engine body to the retarder and from the retarder to the cooler are also separate. Furthermore, to improve pipe stability, the pipes from the engine body to the retarder and from the retarder to the cooler are each secured with separate fixings, resulting in a larger number of parts and, in turn, increased engine cost.

[0003] This case was created to solve the above problems. Utility Model Content

[0019] An opening 21 is provided at one end of pipe 2, and an opening 3 22 is provided at the other end. The bend of pipe 2 2 at opening 3 22 is wrapped around the closed end of pipe 1, that is, the bend of pipe 2 2 is also fixedly connected to the closed end of pipe 1, and the connecting surfaces between pipe 1 and pipe 2 2 are perpendicular to each other, making the connection more stable and firm.

[0020] A fixed connection mechanism 4 is connected to the side of pipe 2 2 away from pipe 1 1 and the bottom of pipe 1 1 and pipe 2 2. Pipe 1 1 and the diversion pipe 3 are fixed by the fixed connection mechanism 4. A reinforcing plate 5 is provided at the connection between the pipe 1 and the diversion pipe 3.
