An air filter is arranged on one side of a crankcase, a filtration assembly is arranged inside a casing of the air filter, the inside space of the air filter is divided into a gas incoming cavity and a gas outgoing cavity by the filtration assembly, a waste gas inlet and a condensation oil outlet are arranged in the gas incoming cavity, a vent is arranged in the gas outgoing cavity, the waste gas inlet is communicated with an inner cavity of the crankcase through a waste gas duct, the condensation oil outlet is communicated with the inner cavity of the crankcase through an oil return duct, and the vent is communicated with a gas incoming pipeline of the gasoline engine through a duct. The environment-friendly power gasoline engine has the advantages that oil of the crankcase can be recovered and reutilized by a crankcase waste gas recovering device, the carbon deposition in a cylinder is avoided, and the service life of the engine is long; and CO and HC contents in the tail gas discharged by the gasoline engine are effectively lowered, so that the environment-friendly power gasoline engine is suitable for various places needing gasoline engines, and has a large market prospect.
Description
Technical field
The utility model belongs to the technology of gasoline engine field, refers 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 the utility model provides a kind of cylinder can not produce carbon distribution, and the power in environmental protection petrol engine of discharging National standard.
The purpose of the utility model is achieved in that 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 utility model is compared the outstanding and beneficial technical effects of existing technology:
1, the machine oil of the utility model crankcase 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 utility model has reduced the waste of resource, and has effectively reduced CO and HC content in the gasoline exhaust tail gas, has great market prospects.
Description of drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the crankcase waste gas recovering device structure diagram of the utility model.
Embodiment
The utility model 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.
The utility model working procedure: 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 trap 9 through withdrawing oil outlet 10; Condensation machine oil compiles and gets back to through the oil return conduit 22 that is communicated with condenser oil export 7 inner chamber of crankcase 2 in oil trap 9; Waste gas after the filtration gets into outlet chamber 12, and mixes with fuel oil through the air inlet pipeline of the 6 entering petrol engine of the vent in the outlet chamber 12, gets into combustion chambers burn again.
The foregoing description is merely the preferred embodiment of the utility model, is not the protection domain that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection domain of the utility model.
