Abstract
The invention belongs to the technical field of gasoline engines, in particular to an environment-friendly power gasoline engine. An air filter is arranged on one side of a crankcase; a filter component is arranged inside a shell of the air filter and is used for partitioning the internal space of the air filter into a gas inlet cavity and a gas outlet cavity; a waste gas inlet or a condensation machine oil outlet are formed in the gas inlet cavity; a gas through hole is formed in the gas outlet cavity; the waste gas inlet is communicated with the inner cavity of the crankcase through a waste gas guiding pipe; the condensation machine oil outlet is communicated with the inner cavity of the crankcase through an oil return guiding pipe; and the gas through hole is communicated with a gas inlet pipeline of the gasoline engine through a guiding pipe. The invention has the advantages that: machine oil of the crankcase can be recycled by a waste gas recycling device of the crankcase, carbon cannot be deposited in a cylinder, and an engine has long service life; the content of CO and HC in tail gas emitted by the gasoline engine is effectively reduced; and the gasoline engine is suitable for various occasions which require the gasoline engines and has an extremely good market prospect.
Description
Technical field
The invention belongs to the technology of gasoline engine field, refer in particular to a kind of power in environmental protection petrol engine.
Background technique
At present, when the petrol engine on the market was worked, the crankshaft-and-connecting-rod mechanism in the crankcase of petrol engine ran up and produces the waste gas that contains oil formulation; The waste gas of discharging contains oil formulation; Not only cause the waste of the energy but also do not meet environmental protection requirement, most petrol engine all directly imports waste gas in the cylinder with after fuel oil mixes and burns, because the performance difference of machine oil and gasoline; Fuel nozzle and igniter in the process of burning in the gasoline engine cylinder can produce carbon distribution; Influence the normal use of petrol engine, and machine oil is not easy perfect combustion, discharge tail gas pollutes the environment.
Summary of the invention
The purpose of this invention is to provide a kind of cylinder and can not produce carbon distribution, and the power in environmental protection petrol engine of discharging National standard.
The objective of the invention is to realize like this: a kind of power in environmental protection petrol engine; Side setting at crankcase is free filter; Said empty filter comprises base, be fixed on housing on the base, be arranged on the filter assemblies of enclosure interior, and said filter assemblies is divided into air-inlet cavity and outlet chamber with the inner space of empty filter, is provided with waste gas inlet and condenser oil export in the air-inlet cavity; Be provided with vent in the outlet chamber; Said waste gas inlet is through the inner chamber conducting of waste gas duct and crankcase, and said condenser oil export is through the inner chamber conducting of oil return conduit and crankcase, and said vent is through the air inlet pipeline conducting of conduit and petrol engine; The bottom of said air-inlet cavity is provided with oil trap, and said condenser oil export is arranged on the bottom surface of oil trap.
The above-mentioned waste gas inlet that is arranged in the air-inlet cavity is higher than the condenser oil export.
The filter assemblies of above-mentioned empty filter is a cylindrical housings, and the side of cylindrical housings is metal net shaped structure, and the inside and outside both sides of metal net shaped structure all are coated with filter core.
The bottom of above-mentioned cylindrical housings is provided with oil flow hole, and said filter core is sponge or filter core made of paper.
The present invention compares the outstanding and beneficial technical effects of existing technology:
1, the machine oil of crankcase of the present invention can be recycled, and has reduced the frequency of maintenance of motor, and the cylinder of petrol engine can not produce carbon distribution, has prolonged motor working life.
2, the present invention has reduced the waste of resource, and has effectively reduced CO and HC content in the gasoline exhaust tail gas, has great market prospects.

Fig. 2 is a crankcase waste gas recovering device structure diagram of the present invention.
Embodiment
The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2;
A kind of power in environmental protection petrol engine; Side setting at crankcase 2 is free filter 1; Said empty filter 1 comprises base 13, be fixed on housing 3 on the base 13, be arranged on the inner filter assemblies 5 of housing 3, and said filter assemblies 5 is divided into air-inlet cavity 11 and outlet chamber 12 with the inner space of empty filter 1, and 11 are provided with waste gas inlet 8 and condenser oil export 7 in the air-inlet cavity; Be provided with vent 6 in the outlet chamber 12; Said waste gas inlet 8 is through the inner chamber conducting of waste gas duct 21 with crankcase 2, and said condenser oil export 7 is through the inner chamber conducting of oil return conduit 22 with crankcase 2, and said vent 6 is through the air inlet pipeline conducting of conduit and petrol engine; The bottom of said air-inlet cavity 12 is provided with oil trap 9, and said condenser oil export 7 is arranged on the bottom surface of oil trap 9.
The above-mentioned waste gas inlet 8 that is arranged in the air-inlet cavity is higher than condenser oil export 7.
The filter assemblies 5 of above-mentioned empty filter is a cylindrical housings; The side of cylindrical housings is metal net shaped structure; The inside and outside both sides of metal net shaped structure all are coated with filter core 4, and filter core 4 can filter waste gas, make oil formulation condensation on filter core 4 in the waste gas.
The bottom of above-mentioned cylindrical housings is provided with oil flow hole 10, and oil flow hole 10 is arranged on the bottom of filter core 4, and the machine oil of condensation can splash in the oil trap 9 through oil flow hole 10, and said filter core 4 is sponge or filter core made of paper.
Working procedure of the present invention: the waste gas in the crankcase 2 gets into the air-inlet cavity 11 of empty filter through the waste gas inlet 8 that is connected with waste gas duct 21; When getting into the outlet chamber 12 of empty filter through filter assemblies 5, separates waste gas with its contained oil formulation; Machine oil gas is stayed on the filter core 4 and is condensed into liquid; The machine oil of condensation flows in the oil traps 9 through withdrawing oil outlet 10, and condensation machine oil compiles in oil trap 9 and gets back to the inner chamber of crankcase 2, the waste gas entering outlet chamber 12 after the filtration through the oil return conduit 22 that is communicated with condenser oil export 7; And the air inlet pipeline that gets into petrol engine through the vents in the outlet chamber 12 6 mixes with fuel oil, gets into combustion chambers burn again.
The foregoing description is merely preferred embodiment of the present invention, is not to limit protection scope of the present invention according to this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
