Description

Technical Field

[0001] This utility model relates to the technical field of diesel engine intake pipes, specifically a straight diesel engine intake pipe. Background Technology

[0002] The diesel engine intake manifold is a crucial component connecting the air filter and the engine cylinders. Its main function is to introduce filtered air into the engine cylinders, providing the necessary air for the diesel engine's combustion process. Its specific structure includes an intake port, which connects to the air filter via an intake interface at the top to introduce clean air. The air then enters the entire intake manifold body and branches out through the outlet, each branch corresponding to a cylinder, distributing the air evenly to each cylinder. The connections between each branch and the cylinders are secured with bolts. Over time, these bolts often loosen, affecting the sealing of the connection and leading to air leakage. Utility Model Content

[0003] The purpose of this utility model is to provide a straight diesel engine intake pipe to solve the problem mentioned in the background art, where the various branches of the intake pipe on the market often experience loose bolts and air leakage when connected to external cylinders and other equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a straight diesel engine intake pipe, comprising an intake pipe body, wherein the intake pipe body is arranged in a straight structure, and an exhaust port is provided at equal intervals on one side thereof. An intake port and an EGR port are respectively provided at the bottom of the intake pipe body. Two threaded holes are symmetrically arranged on the outside of the exhaust port for connecting with external equipment via screws and nuts. A fastening component is provided at the top of the intake pipe body for fastening the screw after installation.

[0005] Preferably, the outer side of the air outlet is provided with a groove for the installation of the seal.

[0006] Preferably, the fastening assembly includes a fastener, a reserved groove, and a reserved hole. The reserved groove is arranged in an arc shape, and its position corresponds to the threaded hole protruding from the outside of the air outlet.

[0007] Preferably, an arc-shaped fastener is provided above the reserved slot, and both the fastener and the air intake pipe body are provided with reserved holes.

[0008] Preferably, the interior of the reserved hole has a threaded structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The straight diesel engine intake pipe is equipped with a fastening component. After the external bolt or screw passes through the threaded hole at the top of the exhaust port for fastening, it will reach the interior of the reserved groove. With the setting of the arc-shaped fastener, the top of the bolt or screw can be fastened, so as to achieve the purpose of fastening and limiting the bolt or screw. This setting can firmly fix the bolt, making the connection between the exhaust port and the external equipment more stable. This can reduce the damaging effect of vibration on the connection part and avoid the loosening of the screw and nut due to vibration.

[0010] The top of the air intake port has a groove, which can be used to engage seals such as rubber gaskets to achieve a tight fit with the surface of the air intake port and form a good seal. This tight fit can effectively prevent air leakage and ensure that the air pressure and flow in the air intake pipe remain stable. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: a straight diesel engine intake pipe, including an intake pipe body 1, the intake pipe body 1 is arranged in a straight structure, and an exhaust port 2 is arranged at equal intervals on one side. An intake port 4 and an EGR port are respectively arranged at the bottom of the intake pipe body 1. Two threaded holes 8 are symmetrically arranged on the outside of the exhaust port 2 for connecting with external equipment by screw and nut. A fastening component is provided at the top of the intake pipe body 1 for fastening the screw after installation.

[0018] The outer side of the air outlet 2 is provided with a groove 7 for the installation of the seal.

[0019] This application provides an intake pipe structure with fastening components. Specifically, in use, firstly, the intake port 4 at the bottom of the intake pipe body 1 is bolted to the external air filter, the EGR port is bolted to the EGR valve, and the exhaust port 2 is connected to the external cylinders or equipment with screws and nuts. After connection, the installed screws are fastened by the fastening components.

[0020] After the outside gas passes through the air filter and reaches the position of the air intake port 4, it enters the interior of the air intake pipe body 1, and then reaches the external equipment or cylinder through the various air outlet ports 2 on the outside of the air intake pipe body 1. In the cylinder, it mixes with the injected diesel to form a combustible mixture. Throughout the process, due to the setting of fastening components, the screw nut can be limited to avoid the screw nut from loosening and being damaged due to vibration.

[0021] The fastening assembly includes a fastener 3, a reserved groove 5, and a reserved hole 6. The reserved groove 5 is arranged in an arc shape and its position corresponds to the threaded hole 8 protruding from the outside of the air outlet 2.
