Abstract
The utility model relates to an oil and gas separating structure of an engine cylinder head cover. The oil and gas separating structure comprises an engine cylinder head and a cylinder head cover, and is characterized in that a labyrinth passage is arranged inside the cylinder head cover, a cover plate, a cylinder head cover wall plate, a first transverse partition plate and a second transverse partition plate are connected in the labyrinth passage, the labyrinth passage is divided into a first cavity, a second cavity, a first filter screen passage and a second filter screen passage by the cylinder head cover wall plate, the first transverse partition plate and a second transverse partition plate, and a first filter screen, a second filter screen, a third filter screen and a fourth filter screen are respectively arranged on the first cavity, the second cavity, the first filter screen passage and the second filter screen passage. The oil and gas separating structure is capable of effectively controlling reduction of performance of an engine and increase of emission caused by the fact that mixed gas with over-high oil content is exhausted into the air via a gas outlet, reducing oil consumption of the engine, reducing flow rate of oil and gas mixture in the labyrinth passage and guaranteeing a long flowing path of the oil and gas mixture.
Description
Technical field
The utility model relates to a kind of engine air cylinder cap gas oil separation structure, specifically covers the interior gas oil separation structure of valve mechanism cover of cylinder head top.
Background technique
In prior art, the gas oil separation structure of motor all is to form by valve mechanism cover inwall and air outlet and filter screen.The path that oil gas passes through is shorter, and Oil-gas Separation is insufficient, and a large amount of fuel-air mixtures is discharged in the ambient air by the air outlet, and environment is caused severe contamination.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of engine air cylinder cap gas oil separation structure, this separation structure can effectively suppress because of the too high mixed gas of oil content is discharged into the engine performance decline that causes in the air, the increase of exhaust emissions by the air outlet, and can reduce the oil consumption of motor; Can reduce the flow velocity of fuel-air mixture in labyrinth channel, and guarantee the path length that fuel-air mixture passes through, be used for separating and removing the mist of oil of mixed gas.
The technological scheme that provides according to the utility model, a kind of engine air cylinder cap gas oil separation structure comprises engine cylinder cap, valve mechanism cover, the engine cylinder cap top connects valve mechanism cover, feature is: described valve mechanism cover inside is provided with labyrinth channel, be connected with cover plate in the described labyrinth channel, the valve mechanism cover coaming plate, the first tabula baffle plate, the second tabula baffle plate, the described valve mechanism cover coaming plate and the first tabula baffle plate and the second tabula baffle plate are cut apart formation first chamber with labyrinth channel, second chamber, the first filter screen passage and the second filter screen passage are in first chamber, second chamber, place first filter screen respectively on the first filter screen passage and the second filter screen passage, second filter screen, the 3rd filter screen and the 4th filter screen.
Described labyrinth channel ingress is provided with retaining mist of oil structure.Described cover plate is provided with oil-collecting groove and spill port.Top, described valve mechanism cover side is provided with air outlet hole.
Compared with the prior art the utility model has the following advantages:
The utility model is rational in infrastructure, design is ingenious, Oil-gas Separation efficient height; Owing in labyrinth channel, form two chambeies, can guarantee that the flow velocity of fuel-air mixture is relatively low, pass through path length, and can improve the removal effect of mist of oil.Retaining mist of oil structure is set in the ventilation chamber ingress, before oil gas enters labyrinth channel inside, the part mist of oil attached on the oil baffle structure and be removed, can be prevented that too much mist of oil from entering labyrinth channel.Setting is positioned at the air outlet hole of valve mechanism cover inside top and places filter screen in the gas oil separation structure outlet port, helping fuel-air mixture separates once more, preventing that fuel-air mixture from can't fully separate to be drained into by the air outlet in labyrinth channel causes engine performance to descend in the air, exhaust emissions increases.Be provided with oil-collecting groove and some spill ports in labyrinth channel cover plate position in addition, the oil of separating in the labyrinth channel can be flowed back to motor naturally, can reduce the oil consumption of motor.

Embodiment
Example during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 5, comprise cylinder head 1, valve mechanism cover 2, the labyrinth channel 3(first chamber 3a, the second chamber 3b, the first filter screen passage 3c and the second filter screen passage 3d of motor), cover plate 4, valve mechanism cover coaming plate 5, retaining mist of oil structure 6, the first tabula baffle plate 7, the second tabula baffle plate 8, oil-collecting groove 9, spill port 10, first filter screen 11, second filter screen 12, the 3rd filter screen 13, the 4th filter screen 14 and air outlet 15 etc.
The utility model adopts and connect valve mechanism cover 2 above engine cylinder cap 1, feature is: described valve mechanism cover 2 inside are provided with labyrinth channel 3, be connected with cover plate 4 in the described labyrinth channel 3, valve mechanism cover coaming plate 5, the first tabula baffle plate 7, the second tabula baffle plate 8, the described valve mechanism cover coaming plate 5 and the first tabula baffle plate 7 and the second tabula baffle plate 8 are cut apart the formation first chamber 3a with labyrinth channel 3, the second chamber 3b, the first filter screen passage 3c and the second filter screen passage 3d are at the first chamber 3a, the second chamber 3b, place first filter screen 11 respectively on the first filter screen passage 3c and the second filter screen passage 3d, second filter screen 12, the 3rd filter screen 13 and the 4th filter screen 14.Can reduce oil gas in labyrinth channel 3 flow velocity and guarantee the path length that passes through of oil gas, be used for separating and removing the mist of oil of oil gas.
Retaining mist of oil structure 6 is set in described gas oil separation structure oil gas labyrinth channel 3 ingress, before oil gas enters labyrinth channel 3 inside, the part mist of oil is removed attached to keeping off on the mist of oil structure 6, can prevent that too much mist of oil from entering labyrinth channel 3, guarantee that oil gas can effectively separate in the labyrinth channel 3.
