Abstract
The utility model provides a crankcase ventilation system of a hydrogen-powered engine. The system comprises a cylinder head cover, a pipeline, an adjusting valve, an oil-gas separator and an oil pan; an oil gas outlet of the cylinder head cover is connected with the oil-gas separator through the pipeline; one end of the adjusting valve is connected with a top outlet of the oil-gas separator, and the other end thereof is connected with a suction manifold; ignition coil mounted holes are distributed on the inner surface of the cylinder head cover; the oil gas outlet is formed at the side edge of the cylinder head cover, that is to say, the cylinder head cover is not provided with a labyrinth structure; the pipeline adopts a spiral pipe penetrating out of the oil gas outlet and downwardly and spirally connected to the oil-gas separator; an out pipeline at the bottom of the oil-gas separator is connected with a collecting bottle instead of an oil pan. The system has the advantages of easy processing and manufacturing and better cooling effect, and can efficiently solve the problem of oil-water blending.
Description
Technical field
The utility model relates to automobile engine system, is specifically related to a kind of engine crankshaft ventilation system.
Background technique
Hydrogen is as a kind of new energy, obtains more and more widely application with its superior self-characteristic at automotive field, can satisfy strict further motor vehicle emission requirement, is the effective alternative fuel that satisfies Abgasgesetz, solves environmental problem.But, use hydrogen as automotive fuel, its products of combustion brings many difficult problems but for effective use of motor, for example, the water that its burning generates can cause the profit mixing phenomena, serious deterioration engine lubrication oil quality, and long-time running will cause engine lubrication system to lose efficacy.
Evidence, under equal engine operating condition, the quality of water is about five times of conventional gasoline machine in the hydrogen engine products of combustion; In the conventional gasoline machine through crankcase ventilation system residual water vapor serious deterioration lubricant oil quality (in crankcase drain mileage) not, satisfy the usage requirement of present crankcase ventilation system.But, because the content of water significantly raises in the hydrogen engine products of combustion, after traditional crankcase ventilation system separation, will form a large amount of liquid waters and sneak in the lubricant oil, cause the lubricant oil quality to descend, and then cause motor to damage.
Referring to Fig. 1 and Fig. 3, the engine crankshaft ventilation system of present a kind of form mainly comprises valve mechanism cover 1, straight tube 2, modulating valve 3, deaerator 4 and the oil sump 5 of being with labyrinth structure.Valve mechanism cover 1, deaerator 4 and oil sump 5 are linked in sequence by pipeline, and modulating valve 3 is connected with the outlet of deaerator 4 tops by pipeline.The inner face of the valve mechanism cover 1 of this system has maze-type structure 11, and the pipeline that connects valve mechanism cover 1 and deaerator 4 is a straight tube 2, and the bottom of deaerator 4 directly is connected with oil sump 5 by pipeline.
Its working procedure is: the fuel-air mixture that produces in the motor 12 rises, enter in the maze-type structure 11 of valve mechanism cover 1, after valve mechanism cover 1 cooling, some lubricant oil is got back to oil sump 5, remainder then enters deaerator 4 by the road, gas enters in the intake manifold 8 through pressure regulator valve 3 and finally burns after separating, and then gets back to oil sump 5 from the bottom by pipeline through deaerator 4 isolated lubricant oil.
If this structure is used for the hydrogen power engine, just there is following technical problem:
Owing to be furnished with maze-type structure on valve mechanism cover, fuel-air mixture can prolong the cool time of lubricant oil through this, but the water vapour that enters in the crankcase ventilation system through piston ring and spill port simultaneously also is cooled simultaneously, causes profit to mix;
Mazy valve mechanism cover manufacturing cost is higher simultaneously;
And if the labyrinth structure of cancellation valve mechanism cover, though can reduce the manufacturing cost, but cause cool time too short, and lubricant oil can not get abundant cooling, and lubricant oil directly enters the pipeline of straight tube shape like this, because pipeline is the straight tube shape, lubricant oil by wherein, is also suitably cooled off fast, and lubricant oil just flows out from the top outlet without separating promptly in deaerator with gaseous form, enter intake manifold and burn, cause oil consumption excessive;
The parts of lubricating oil and the water vapour that cool down through straight tube mix in deaerator, finally flow back to oil sump again, can cause serious profit mixed problem.
Therefore, existing this structure also is not suitable for using on the hydrogen power engine.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of manufacturing easily, cooling effect hydrogen power engine crankcase ventilation system preferably, it can effectively solve profit mixed problem.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of hydrogen power engine crankcase ventilation system comprises valve mechanism cover, pipeline, modulating valve, deaerator and oil sump; The oil gas vent of described valve mechanism cover connects deaerator by pipeline, and modulating valve one end is connected with the outlet of deaerator top, and the other end is connected with intake manifold; It is characterized in that: be distributed with the spark coil mounting hole on the inner face of described valve mechanism cover, the side of valve mechanism cover is provided with oil gas vent, and promptly valve mechanism cover is not with labyrinth structure.Described pipeline is a volute, and it picks out also from oil gas vent and is connected to deaerator under the screw, and the deaerator bottom picks out pipeline and is not connected with oil sump, but connects a collection bottle.
Compared with prior art, the utlity model has following advantage:
1, employing can reduce the manufacturing cost with the valve mechanism cover of labyrinth structure, reduces the cooling of water vapour on valve mechanism cover;
2, adopt the pipeline of spiral tube structure, can solve owing to adopt the lubricant oil cool time that brings with the valve mechanism cover of labyrinth structure too short and then cause the excessive problem of lubricating oil consumption, prolong the cool time of lubricant oil in pipeline, lubricant oil is cooled off fully;
3, adopt the outlet of deaerator lower end directly to be connected, can avoid lubricant oil directly to enter oil sump, avoid oil water mixture to enter lubrication system, can greatly solve profit mixed problem with collection bottle.
