Embodiment Construction

[0014] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 with image 3 As shown, the mounting base of the high-pressure oil pump of the engine is a two-way body with a 90° channel in the inner cavity. A first flange 2 and a second flange 1 are respectively arranged at both ends of the two-way body. Four flanges are opened on the first flange 2. Only one bolt passes through the hole 4, and two bolt holes 7 are provided on the second flange. A lubricating oil passage 6 is provided at the lower part of the first flange 2 of the two-way body. The oil inlet of the lubricating oil passage 6 is located at the lower part of the end face of the first flange 2, and its oil outlet is located on the inner wall of the two-way body. The diameter of the oil outlet is Like a pinhole, and upward toward the junction of the two...

Abstract

The invention relates to an installation base of a high-pressure oil pump of an engine. The installation base is a two-way body with a 90-degree channel formed in the inner cavity, a first flange and a second flange are arranged at the two ends of the two-way body respectively, a lubricating oil path is formed in the two-way body, an oil return groove communicated with the end face of the first flange is formed in the bottom of the inner wall of the two-way body, a sensor installation boss is integrally arranged on the top of the two-way body, and an oil outlet pipe installation boss is integrally arranged on the lower portion of the two-way body. The high-pressure oil pump is connected with a cylinder cover of the engine through the installation base, a structure for installation and connection of the high-pressure oil pump and the cylinder cover of the engine can be simplified.

Description

technical field [0001] The invention relates to parts of an in-cylinder direct-injection automobile engine, in particular to a mounting base of an engine high-pressure oil pump. Background technique [0002] In-cylinder direct-injection gasoline engine is an automobile engine that provides high-pressure fuel to the engine through a high-pressure oil pump. The high-pressure oil pump of the existing in-cylinder direct-injection gasoline engine is installed at one end of the engine cylinder head. Make the installation connection. For example, the patented technology with the patent number of 200920302271.7 discloses a connection structure of a high-pressure oil pump. In this structure, one end of the high-pressure oil pump is connected with a connecting piece. Bolts are provided and fixedly connected with the cylinder head and tile cover respectively through the connecting piece. This structure has the following disadvantages: 1. The installation and connection structure is c...
