Problems solved by technology

[0007] In the case of damage to the gasket surface of the cylinder head, it is difficult to ensure the sealing performance (sealing) between the gasket surface of the cylinder block and the gasket surface of the cylinder head
[0008] Therefore, it is necessary to perform maintenance / inspection while taking care not to damage the gasket surface of the cylinder head. From this point of view, there is still room for improvement.

Embodiment

[0025] The cylinder head 15 of the internal combustion engine of the embodiment will be described.

[0026] Such as figure 1 , figure 2 As shown, the internal combustion engine 10 is an engine for a generator provided with the following parts: a cylinder block 12 formed with a cylinder 13; a cylinder head (cylinder head of the internal combustion engine) 15 provided on a gasket surface 14 of the cylinder block 12; Cylinder head cover 17 of cover 15 .

[0027] The cylinder head cover 17 is mounted to the mounting boss 21 of the cylinder head 15 via mounting bolts 23 .

[0028] That is, one mounting bolt 23 is screwed to the mounting boss 21 (specifically, the mounting screw hole 22 ) of the cylinder head 15 , whereby the cylinder head cover 17 is mounted to the mounting boss 21 via the mounting bolt 23 .

[0029] In the cylinder block 12 , the piston 25 is slidably housed in the cylinder 13 , and a gasket surface 14 is formed on the top of the cylinder block 12 . The gaske...

Abstract

The invention provides an air cylinder cover of an internal combustion engine and damage to a sealing gasket surface of the ari cylinder cover can be prevented during maintenance and check. A combustion chamber (34) communicated with an air inlet port (32) and an air discharging port (33) is disposed in the air cylinder cover (15) of the internal combustion cover; the sealing gasket surface (35) is arranged on the periphery of an opening part (34a) of the combustion chamber; an air cylinder body (12) is sealed via the sealing gasket surface; the combustion chamber (34) and the air cylinder (13) are arranged on the same axis; the air cylinder cover comprises an air inlet boss part (36) on the periphery of the air inlet port and an air discharging boss part (37) on the periphery of the air discharging port; and a lower protrusion part (36b) of the air inlet boss part protrudes toward the air cylinder body compared with the sealing gasket surface.

Description

technical field [0001] The present invention relates to a cylinder head of an internal combustion engine, wherein a gasket surface is provided around an opening of a combustion chamber, and the gasket surface is sealed to a cylinder block so that the combustion chamber is arranged on the same axis as the cylinder. Background technique [0002] In an internal combustion engine, the gasket surface of the cylinder head is sealed to the gasket surface of the cylinder block through the gasket, so that the combustion chamber of the cylinder head and the cylinder of the cylinder head are arranged on the same axis. [0003] In order to ensure sealing performance (sealing performance), the gasket surface of the cylinder block and the gasket surface of the cylinder head are formed as flat surfaces (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2004-278499 [0005] During servicing / inspection (maintenance) of this internal combusti...
