Abstract
The utility model relates to a lubricating structure of a high-pressure oil pump tappet of a gasoline engine. The lubricating structure is characterized in that an oil passage hole of a cylinder cover is machined on the top surface of the cylinder cover, an oil passage hole of a cylinder cover cap is machined on the cylinder cover cap in the vertical direction of the oil passage hole of the cylinder cover, and the oil passage hole of the cylinder cover is connected with the oil passage hole of the cylinder cover cap. By adoption of the lubricating structure, the working temperatures of the high-pressure oil pump tappet and a drive cam are effectively reduced, the thermal load is improved, and the durability of the high-pressure oil pump tappet is enhanced.
Description
Technical field
The utility model relates to a kind of lubricating structure of gasoline engine high pressure oil pump tappet, is to add cylinder cap and cylinder head cover cap through machine, has realized giving the high pressure oil pump tappet lubricated structure.
Background technique
Present most gasoline engine high pressure oil pump tappet all adopts the mode of oil mist lubrication; Not separately to the lubricated mechanism of tappet; Because petrol engine rotational speed is very high; Heat load is very big in the high pressure oil pump working procedure, and this lubricating system is unfavorable for reducing high pressure oil pump tappet operating temperature, and reliability, durability are had adverse effect.
Summary of the invention
The purpose of the utility model is to provide a kind of lubricating structure of gasoline engine high pressure oil pump tappet, and it effectively reduces high pressure oil pump tappet and driving cam operating temperature, has improved heat load, has improved the endurance quality of high pressure oil pump tappet.
The technological scheme of the utility model is achieved in that a kind of lubricating structure of gasoline engine high pressure oil pump tappet; It is characterized in that: in the top surface of cylinder cover machining cylinder cap oil channel hole; And the cylinder head cover cap oil channel hole that covered also machining of the valve mechanism cover on cylinder cap oil channel hole Vertical direction, the cylinder cap oil channel hole links to each other with cylinder head cover cap oil channel hole.
The good effect of the utility model is to add cylinder cap and cylinder head cover cap through machine; Realized giving the high pressure oil pump tappet lubricated; Reduce high pressure oil pump tappet and driving cam operating temperature effectively, improved heat load, improved the endurance quality of high pressure oil pump tappet.
Description of drawings
Fig. 1 is a high pressure oil pump tappet lubrication system schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: as shown in Figure 1; A kind of lubricating structure of gasoline engine high pressure oil pump tappet; It is characterized in that: in the top surface of cylinder cover machining cylinder cap oil channel hole; And the cylinder head cover cap oil channel hole 1 that covered also machining of the valve mechanism cover on cylinder cap oil channel hole Vertical direction, the cylinder cap oil channel hole links to each other with cylinder head cover cap oil channel hole.Two oil channel holes link to each other and have realized lubricated to high pressure oil pump tappet 2, and whole lubricating oil path has formed circulation from cylinder body main oil gallery-cylinder cap oil duct-cylinder head cover cap oil channel hole 1-oil pan.
When high pressure oil pump is worked; High pressure oil pump tappet heat load is very high; Machine oil was gone up the cylinder cap oil duct always from the cylinder body main oil gallery and was got into cylinder head cover cap oil channel hole 1 then and realize high pressure oil pump tappet 2 lubricatedly this moment, and the existing oil pan that directly flows back in lubricated back is realized circulating.
