CYLINDER HEAD

摘要

The present invention relates to a cylinder head which comprises: a fuel injection valve line installed at the center of the cylinder head, and having a fuel injection valve inserted thereinto; an air starting valve line installed in front of a fuel injection valve line, and having an air starting valve inserted thereinto; a control air line and a main starting air line tilted at certain angles, and installed to be perpendicular to the air starting valve line; and a nozzle cooling oil line and a fuel supply line tilted at the certain angles, and installed to be perpendicular to the fuel injection valve. Therefore, according to the present invention, the air starting valve of the cylinder head can be easily repaired, inspected, and replaced after separated from the cylinder head without the removal of a connection piece, thereby reducing maintenance time, preventing the loss of parts during operation, and reducing defects in casting.
