Embodiment Construction

[0010] In order to further understand the inventive content, features and effects of the present invention, the following examples are exemplified and described in detail with the accompanying drawings as follows:

[0011] like figure 2 shown,

[0012] A diesel engine exhaust manifold fixing device, comprising an exhaust manifold 1, the root of the exhaust manifold is respectively provided with fixed flanges 2 on both sides of the exhaust manifold, and the two ends of the fixed flange are respectively provided with Fixing countersink 3, the fixing countersink is adjacent to the fixing block 4, the fixing block is pierced with fixing bolts 5 through the light holes on it, the threaded part of the fixing bolt protrudes from the fixing block, and the two fixing sinks located on the adjacent fixing flanges. The holes are compressed by the same fixing block. Each exhaust manifold is fixed by four fixing blocks. In order to reflect the fixed counterbore, the four fixing blocks ar...

Abstract

The invention relates to a diesel engine exhaust manifold fixing device. The diesel engine exhaust manifold fixing device comprises an exhaust manifold and is characterized in that fixing flanges are arranged on the portions, on the two sides of the exhaust manifold, of the root of the exhaust manifold respectively, fixing countersinks are formed in the two ends of each fixing flange respectively and connected with corresponding fixing blocks, each fixing block is provided with a fixing bolt in a penetrated mode through an unthreaded hole in the fixing block, the threaded part of each fixing bolt extends out of the corresponding fixing block, and the two fixing countersinks located in every two adjacent fixing flanges are pressed by the same corresponding fixing block. The diesel engine exhaust manifold fixing device has the advantages that the influence on the bolts by heat loads can be reduced, and then the fixation reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a diesel engine exhaust manifold fixing device. Background technique [0002] At present, with the development and maturity of diesel engine technology, the performance of the engine is improved, and the thermal load on the exhaust manifold is also increasing. The exhaust manifold is the first component that the high-temperature exhaust gas of the engine passes through. It works in a state of alternating heat and cold for a long time. If it is caused by heat load during the working process, it will affect the reliability of the engine. and engine emissions. like figure 1 As shown, in the prior art, the fixing flanges 2 on both sides of the exhaust manifold are directly fixed on the body by the spacer 6 and the fixing bolts. At this time, the heat transfer distance between the fixing bolts and the exhaust The effect of changes in the heat load of the air mani...
