[0005] Furthermore, there are four ignition coil mounting seat holes.

[0006] Furthermore, the above-mentioned fixing hole seats are respectively arranged between the first ignition coil mounting seat hole and the second ignition coil mounting seat hole and between the third ignition coil mounting seat hole and the fourth ignition coil mounting seat hole.

[0007] Furthermore, the thickness of the sealing gasket is equal to the height of the convex strip.

[0008] Compared with the existing technology, this application can achieve the following technical effects:

[0009] The utility model provides a sealing groove on the installation end face of the cylinder head cover body, the sealing groove cooperates with the raised portion of the end face of the cylinder block, a sealing glue is provided between the two, a sealing gasket is provided between the cylinder head cover body and the cylinder block, the raised strip on the cylinder head cover body abuts against the sealing strip of the cylinder block, and finally the cylinder head cover body and the cylinder block are fixedly connected by screws passing through the fixing holes and the fixing hole seats. The locking pressure and triple seal can improve the sealing performance of the engine and avoid the occurrence of oil leakage and pressure relief.

[0010] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
