Abstract
An oil-gas separator comprises a shell, an S-shaped mixed gas channel, a maze structure and a cyclone structure. The shell is mounted on a cylinder head cover and internally provided with the S-shaped mixed gas channel. The maze structure and the cyclone structure are arranged in the shell. The technical scheme includes that a mixed gas inlet of the mixed gas channel is formed in the bottom of one end of the shell, a retainer platform structure is arranged at the mixed gas inlet, the maze structure is arranged between the mixed gas inlet and the mixed gas channel, the cyclone structure is arranged at the tail of the mixed gas channel, oil return control valves are arranged at the bottoms of the mixed gas channel and the cyclone structure, and a gas exhaust end of the cyclone structure is provided with a one-way valve and a PCV (positive crankcase ventilation) valve. In this way, the problems of the conventional oil-gas separator such as poor separating effect, high production cost, low separating efficiency and complicated structure are thoroughly solved.
Description
Technical field
The present invention relates to field of internal combustion engine, particularly relate to a kind of engine components, specifically a kind of multi-functional, integrated, high efficiency deaerator.
Background technique
At present in the machinery industry such as automobile making, internal-combustion engine, deaerator is mainly used in the machine oil in the fuel-air mixture in crank case of internal combustion engine to separate, reduce engine oil consumption, reduce the pollution to environment, but along with the requirement of Abgasgesetz is more and more stricter, the poor efficiency deaerator of single structure cannot meet the demands.Machine oil after separation is mainly through getting back to oil sump with under type: 1, directly dripping to crankcase by spill port returns oil sump, but the mixed gas of crankcase can enter into deaerator by spill port, thus affects separation effect; 2, get back to oil sump by external pipeline, but which increases the volume of overall engine, machine oil gets back to oil sump by cylinder block and head, increases the complexity of cylinder block and head structure, improves manufacture cost.Gas after separation is got back to intake manifold by external pipeline and is participated in burning, is subject to use in winter environmental limit, is arranged in the peripheral ventilation duct Louis of motor and freezes, cause motor normally to work.In addition, because petrol engine volume is little, compact structure, the deaerator with single machine oil separation function is difficult to the overall usage requirement meeting petrol engine.
The utility model patent being CN 202100297U as Authorization Notice No. discloses one " oil-gas separating mechanism for crank case ventilating system of automobile engine ", comprise cylinder head cover and dividing plate, cast-in diaphragm, oil baffle, also comprise bulkhead bracket and cyclone type oil-gas separator, form two-stage piece-rate system.Integrated labyrinth and cyclone type oil-gas separator, in one, enhance the effect that engine oil gas is separated, and simplify the structural configuration of crankcase ventilation system, increase complete machine compactedness, reduce and alter alopecia areata danger.But it still has following defect: have employed the complexity that too much whirlwind deaerator improves structure, add manufacture cost; Cyclone structure and labyrinth structure are positioned in same level, are unfavorable for improving separation effect, and separating effect is undesirable; Lack peripheral passage, after Oil-gas Separation, can not burning be participated in directly, be unfavorable for the performance improving motor; Lack structure of rising again in loop, use in winter easily freezes.
Summary of the invention
The object of this invention is to provide a kind of deaerator, fundamentally solve existing deaerator inferior separating effect, manufacture cost is high, separation effect is low, complex structure and other problems.
The object of the present invention is achieved like this: this deaerator comprises the housing be arranged on cyclinder head cover, be arranged on the S shape mixed gas passage in housing, be arranged on the labyrinth structure in housing and cyclone structure, its technological points is: the mixed gas entrance of described mixed-gas channel is positioned at the bottom of shell one end, mixed gas entrance is provided with gear platform structure, labyrinth structure is between mixed gas entrance and mixed gas passage, cyclone structure is positioned at the end of mixed gas passage, oil return control valve is provided with bottom mixed gas passage He bottom cyclone structure, the exhaust end of cyclone structure is respectively equipped with one-way valve and Pcv valve.
The advantage that the present invention has and positive technique effect are: labyrinth deaerator and whirlwind deaerator are integrated, and realize two-stage and are separated, improve separation effect; Every grade of drainback passage is equipped with oil return control valve, not only improves separation effect, and simplify engine structure; The integrated Pcv valve of cyclone structure exhaust end and one-way valve, arrange air pipeline, and integrated several functions in limited space, achieves the requirement of motor compactness;
Deaerator is arranged on cyclinder head cover, and the mixed gas of crankcase, by deaerator, carries out one-level crude separation through labyrinth structure, then carries out secondary essence through cyclone structure and is separated.Two-stage is separated and respectively establishes a drainback passage, makes the machine oil after separation get back to oil sump.Each drainback passage is equipped with control valve, prevents the mixed gas of crankcase from entering deaerator inside by drainback passage, thus improves separation effect.Gas after separation enters cylinder by two paths and participates in burning, and one of them channel setting, at separator interior, directly arrives cylinder cap through cyclinder head cover, utilizes the temperature of motor itself to heat mixed gas passage, prevents freezed in winter, pipeline blockage.Meet on the basis of separating mixed gas at deaerator, the function of bent case ventilation channel, medley crankcase ventilation Pcv valve and one-way valve is set.
