Embodiment Construction

[0039] Exemplary embodiments of the present invention will hereinafter be described in detail with reference to the accompanying drawings.

[0040] figure 1 is a partial perspective view of a gasoline direct injection engine equipped with a fuel pump device according to an exemplary embodiment of the present invention.

[0041] refer to figure 1 , the engine includes a cylinder head 100 , a cylinder head cover 120 and an adapter 110 .

[0042] The cylinder head cover 120 is located above the cylinder head 100, and the cylinder head cover 120 is fixed to the cylinder head 100 by fixing bolts at the edge of the cylinder head cover.

[0043] The adapter 110 is combined with the cylinder head 100, and the mounting hole 600 ( Image 6 ) is formed in the cylinder head cover 120 through which the adapter extends.

[0044] A mounting surface to which the fuel pump 130 is attached is formed on an upper end surface of the adapter 110, and a first bolt hole 140 is formed on the mount...

Abstract

The present invention provides a direct gasolene injection engine equipped with an oil fuel pump which comprises a cam axle installed on a cylinder cap, an adapter integrally formed by a cam at one side of the cam axle and a cam cover installed on the cylinder cap for supporting the cam axle, an oil fuel pump installed on the adapter and spraying out fuel oil according to the rotation of the cam axle, a cylinder head cover with one side combined with the cylinder head and the other side combined with the adapter. A sealing member is inserted between the adapter and the cylinder head cover, the adapter and the cylinder head cover are combined by a screw bolt, therefore improving the sealing and fixing structure. Furthermore, a sheet-like cushion ring is used for sealing the gapping place between the bolt head and the cylinder head cover, therefore improving wearing property and sealing structure. Furthermore, the mounting face of the upper part of the adapter is inclined by a predetermined angle, the oil fuel pump is installed on the installation surface to make the assembling of the oil fuel pump easier and the sealing structure more compact.

Description

[0001] Cross References to Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2008-0117556 filed with the Korean Intellectual Property Office on November 25, 2008, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a direct-injection engine equipped with a fuel pump device, and more particularly, the present invention relates to a sealing structure and an assembly structure of a gasoline direct-injection engine equipped with a fuel pump. Background technique [0004] A gasoline direct injection (GDI) engine that directly injects gasoline into a cylinder has been studied, and the gasoline direct injection engine uses a lean air / fuel ratio operation method and thus has low fuel consumption. And, its intake efficiency and output are improved at the same time. [0005] Gasoline direct injection engines can achieve higher compression ratios than normal gasoline...
