Problems solved by technology

It includes a PCV valve cover, a PCV valve base, a main shell, a filter element, a PCV valve diaphragm, a PCV valve spring, an O-ring, and a bracket insert; the PCV valve cover, the PCV valve base, and the main shell are closely connected in sequence Then, the side wall of the PCV valve base is provided with an air outlet, a PCV valve diaphragm is provided between the PCV valve cover and the air outlet of the PCV valve base, and a PCV valve diaphragm is provided between the PCV valve diaphragm and the PCV valve base. PCV valve spring, the side wall of the main housing is provided with a mixed air inlet, and the main housing is provided with a filter element and an oil return port at the lower part. The filter element includes a filter element shell, filter cotton, filter element regulating valve, filter element seat Filter element spring, filter element spring leaf, and filter element lower shell; however, this structure cannot be integrated with the cylinder head, and the air intake can only be side air intake, not lower air intake. The mixed gas passes through the filter element from one side, so this structure cannot be set on the Chinese utility model whose application number is 201620915813.8

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 with Image 6 As shown, the present invention provides a horizontal oil-gas separator for diesel engines, which includes a housing 1 and a filter element 2. The housing 1 is divided into upper and lower parts, which facilitates the injection molding of the housing 1 after being set up in this way. After the upper and lower parts are welded A housing 1 is formed, and the filter element 2 is an existing filter element; the housing 1 is provided with a filter chamber 3 and a buffer chamber 4, the volume of the buffer chamber 4 is 1.5 to 3 times the volume of the filter chamber 3, and the filter chamber 3 is located in the transverse direction of the buffer chamber 4 One side of the filter chamber 3 communicates with the buffer chamber 4; the bottom of the filter chamber 3 ...

Abstract

The invention discloses a horizontal type oil-gas separator for a diesel engine. The horizontal type oil-gas separator comprises a shell (1) and a filter element (2). The shell (1) is internally provided with a filter cavity (3) and a buffer cavity (4). The filter cavity (3) is formed in the transverse side of the buffer cavity (4) and communicates with the buffer cavity (4). A gas inlet (5) is formed in the position, below the filter cavity (3), of the shell, wherein the gas inlet (5) allows mixed gas to enter therein. The gas inlet (5) communicates with the filter cavity (3) through a gas inlet channel (6). A gas outlet (7) is formed in the position, above the buffer cavity (4), of the shell (1), and an oil returning opening (8) is formed in the position, below the buffer cavity (4), ofthe shell (1). The filter element (2) is located in the filter cavity (3) and is of an annular structure. An adjustment valve (9) is arranged at the position, above the gas inlet channel (6), inside the filter cavity (3). The outer diameter of the adjustment valve (9) is less than the inner diameter of the filter element (2) but greater than the inner diameter of the gas inlet channel (6). The adjustment valve (9) is eccentrically arranged relative to the gas inlet channel (6). Compared with the prior art, the horizontal type oil-gas separator has the beneficial effects of being high in oil-gas separation efficiency and good in application stability.

Description

technical field [0001] The invention relates to the technical field of engine oil-gas separation, in particular to a horizontal oil-gas separator for diesel engines. Background technique [0002] The oil-air separator is connected next to the crankcase ventilation valve of the engine, because when the engine is working, the blow-by gas of the cylinder and the oil vapor will generate pressure, which will cause damage to the engine, so it needs to be vacuumed through the crankcase ventilation valve, because There is a large amount of oil vapor in the gas extracted by the crankcase ventilation valve, so the oil-gas separator mainly separates the oil vapor into oil and steam, so that the oil is collected by the pan and flows back to the engine for reuse, and the steam flows to the engine for re-combustion. Prevent direct entry into the atmosphere and cause air pollution. [0003] The horizontal oil-gas separator for diesel engines in the prior art, such as the Chinese invention...
