Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of clean type engine gasoline and oil separating device, as shown in Figure 1, it includes engine
1, oil well pump 2, electric heater 3 and knockout drum 4, the arrival end of oil well pump 2 are connected to the sealing of oil sump 101 in engine 1；Oil pumping
The outlet end of pump 2 is connected to by the first conduit 501 with the sealing of the arrival end of the U-tube 301 in electric heater 3；U-tube 301 goes out
Mouth end is connected to by the second conduit 502 with the sealing of spray head 401 in knockout drum 4；Knockout drum 4 passes through third conduit 503 and starts
Air inlet pipe 102 in machine 1 seals connection；Electric heater 3 passes through the first conducting wire 601 and slide rheostat 7, switch 8 and automobile electric power storage
Pond 9 forms series circuit；The outlet end of U-tube 301 is equipped with temperature sensor 10；The measuring head of temperature sensor 10 is hermetically stretched
Enter in U-tube 301；Temperature sensor 10 is connect by the second conducting wire 602 with thermometer 11；The bottom of knockout drum 4 passes through the 4th
Conduit 504 is connected to the bore seal of the crankcase 103 in engine 1；4th conduit 504 is close to the one of the bottom of knockout drum 4

Before.
The working principle of the present apparatus is: the machine oil extraction in oil sump 101 being sent into U-tube 301 using oil well pump 2, U
Type pipe 301 is arranged in electric heater 3, when machine oil passes through U-tube 301, heat exchange can be carried out with the electric heater 3, to mention
The temperature of high machine oil.The temperature of machine oil is increased to 80-100 DEG C, and machine oil is sent in knockout drum 4 by the second conduit 502
On spray head 401, sprayed with mist from spray head.It is more volatile due to the low boiling point of steam oil ratio (SOR) machine oil, within the said temperature range,
The gasoline being dissolved in machine oil, which can gasify, becomes gasoline vapour, and gasoline vapour is sent to air inlet pipe 102 by third conduit 503
It is interior, and combustion process is participated in as the fresh air of entrance is reached together in the cylinder 104 of piston on the side, realize the sharp again of gasoline
With.
Electric heater 3 forms series circuit with slide rheostat 7, switch 8 and automobile storage battery 9 by the first conducting wire 601, closes

Registration on 11 is directly read.After engine 1 just starts, the temperature of engine 1 is minimum, at this time adjustable slide rheostat
7, so that its resistance value is become minimum, keeps the current value in circuit maximum, the heats power of electric heater 3 is also maximum, keeps electric heater 3 fast
Fast heating, improves rapidly the oil temperature flowed through in U-tube 301, and the separation of gasoline is imitated in machine oil when improving 1 cold conditions of engine
Rate.After 1 temperature of engine gradually rises, the oil temperature in oil sump 101 is also gradually risen, and adjusts slide rheostat 7
And increasing its resistance value, the current value reduced in circuit utilizes lesser heating to reduce the heats power of electric heater 3
Power can also be such that the temperature of machine oil reaches in above-mentioned temperature range.
It is returned in crankcase 103, and flow back by the 4th conduit 504 by scavenge oil pump 12 by the machine oil of knockout drum 4
In the oil sump 101 of 103 lower section of crankcase.
The course of work is carried out after the starting of engine 1, and generator 1 constantly charges to automobile storage battery 9,
Place electric heater 3 will not influence the remaining capacity and service life of automobile storage battery 9 to the electric quantity consumption of automobile storage battery 9.
Machine oil in oil sump 101 can be such that the gasoline being mixed into machine oil contains by the above-mentioned flowing that constantly moves in circles
Amount constantly reduces, to improve the cleannes and service life of machine oil.
The connecting portion of the air inlet pipe 102 of third conduit 503 and engine 1 is by being adjusted to air throttle after air throttle 105
Before 105, that is, it is adjusted to the right side of air throttle 105.Using the gasoline vapour separated in knockout drum 4, into air inlet pipe 102
When passing through air throttle 105 afterwards, air throttle 105 is cleaned, removes the machine oil drop being adhered on air throttle 105 in time, protected
The cleaning of air throttle 105 is demonstrate,proved, guarantees that 105 shaft smooth rotation of air throttle, throttle valve 105 can muchly keep normally transporting
Row.
Limiting the scope of the invention, those skilled in the art should understand that, in technical solution of the present invention
On the basis of, the various modifications or variations that can be made by those skilled in the art with little creative work still of the invention
Within protection scope.
