Problems solved by technology

[0006] 2. Now many gasoline engine cylinder head guards have built-in oil and gas separators, and there is no space for high-pressure fuel pump support
[0007] 3. Most gasoline engines now use plastic cylinder head guards. If the high-pressure fuel pump is installed on the plastic cylinder head guard, it is likely that the strength of the cylinder head guard cannot meet the driving force requirements of the high-pressure fuel pump, resulting in pumping oil Reduced efficiency

Abstract

The invention relates to a support integrated with an installation seat of a fuel pump of a gasoline engine. The support is installed at the rear end of an engine cylinder cover. Meanwhile, the support is further integrated with installation seats of a vacuum pump, a high-pressure fuel pump, a hot air water entering steel pipe, a throttle preheating water entering steel pipe, a water temperature sensor and a cam shaft phase sensor. A cavity I, a cavity II, a cavity III and a cavity IV are formed by extending from the surface of the support to a surface. The cavity II and the cavity III are connected. The cavity III is arranged between the cavity II and the installation seat of the high-pressure fuel pump.

Description

technical field [0001] The invention belongs to the field of engine accessories, and refers to a gasoline direct injection engine accessory, in particular to a support integrated with a gasoline engine fuel pump mounting seat. Background technique [0002] Gasoline in-cylinder direct injection engine, this type of engine injects high-pressure gasoline into the cylinder, and requires a high-pressure oil pump to provide high-pressure gasoline. In the past, some engines generally installed the high-pressure oil pump at the timing chain transmission system at the front of the engine, and drove the high-pressure gasoline through the chain transmission system. oil pump. Now there are also high-pressure fuel pumps of the engine that are arranged in the middle of the engine cylinder head, driven by the middle cam of the intake camshaft, so it is necessary to add a high-pressure fuel pump installation position on the cylinder head shield, so that the cylinder head shield Architectur...
