Technical Field
[0001] The utility model relates to the technical field of sealing cover plates, in particular to a sealing cover plate for a cylinder head of a diesel engine. Background Art
[0002] A diesel engine is an engine that burns diesel to release energy. When the engine is running, the cylinder can guide the piston to perform linear reciprocating motion in the cylinder, so that the air in the engine cylinder converts thermal energy into mechanical energy through expansion. The gas in the compressor cylinder is compressed by the piston to increase the pressure. When installing the cylinder, the cylinder needs to be sealed with the help of a cylinder head.
[0003] At present, warping and twisting are common problems of cylinder heads. The deformation of the cylinder head will lead to a loose connection between the cylinder head and the cylinder body plane, causing air leakage and burning of the cylinder gasket. Utility Model Content

[0025] The following further details the present utility model with reference to the accompanying drawings.
[0026] Embodiment:
[0027] Refer to Figures 1-4As shown in the figure, a cylinder head sealing cover plate of a diesel engine disclosed by the present utility model includes a cover plate body 1. A baffle plate 11 is arranged on the top of the cover plate body 1. The upper half of the outer peripheral surface of the cover plate body 1 is circumferentially cut to form an annular groove 12, and a space 13 is formed between the annular groove 12 and the baffle plate 11.
[0028] The outer peripheral surface of the cover plate body 1 is attached to the inner peripheral wall of the cylinder port, and the bottom of the baffle plate 11 is attached to the top surface of the cylinder. At this time, the space 13 forms a closed type.
[0029] A plurality of first through holes 14 are evenly opened along the center of the bottom of the baffle plate 11, and the inside of the first through holes 14 is communicated with the inside of the space 13.
[0030] A second placement groove 2 is opened on the top of the baffle plate 11. A transparent cover plate 21 is arranged at the top opening of the second placement groove 2, and the transparent cover plate 21 is connected to the baffle plate 11 by bolts. The inside of the second placement groove 2 is communicated with the inside of the first through holes 14.
[0031] A detection component 3 is arranged in the second placement groove 2.
