Description
Technical field
The utility model belongs to technical field of engines, and in particular to a kind of two-stroke with internal pressurization function is started
Machine.
Background technology
At present, known model plane two-stroke ignition type engine by main shaft, propeller stator, cam, connecting rod, piston,
Sealing ring, crankcase, back cylinder cover, piston cylinder, carburetor, igniter, bearing etc. form.It is more to improve the air inflow of engine
Number uses turbocharging technology, and existing engine turbine supercharging technology can increase engine volume and weight, be walked on land
The negative effect that automobile, motorcycle etc. are played is less obvious, but is once used in engine model, and drawback is with regard to obvious
More than profit.Pressurized effect more also is played by changing engine piston shape and structure, but this can largely effect on hair
The life-span of motivation, effect are also undesirable.This is new realize by changing cam structure and do not increase engine weight in the case of
Increase oil gas admission pressure, make engine stronger to adaptive capacity to environment, operation is more stable.
Utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of with internal increasing
The two stroke engine of function is pressed, avoids the problems such as conventional engines turbocharging technology increases engine volume and weight.
In order to solve the above-mentioned technical problem used technical scheme is the utility model：One kind has internal pressurization function
Two stroke engine, including cylinder sleeve, carburetor, crankcase, piston, connecting rod and main shaft, a combustion chamber is formed in cylinder sleeve,
The combustion chamber is limited by a reciprocating piston, and wherein piston is connected by a connecting rod with the main shaft in crankcase,
Main shaft is provided with cam with connecting rod junction, and piston reciprocates through the actuated by cams main axis, cam one end and company
Bar is connected, and the other end is provided with towards the side of connecting rod to be used to increase air inflow, axially inclined inclined-plane or curved surface, the inclined-plane
Or curved surface be located at main shaft both sides and incline direction on the contrary, the carburetor is opened on the top of crankcase, and the oil of carburetor
Gas enters Plane of rotation of the direction perpendicular to cam of crankcase.
As a kind of this new further improvement of the two stroke engine with internal pressurization function：Covered on the piston
There is sealing ring.
Beneficial effect
A kind of two stroke engine with internal pressurization function provided by the utility model is originally new compared with prior art
Type is provided with two stroke engine cam to be used to increase air inflow, axially inclined inclined-plane or curved surface, similar to turbine leaf
Fan, when cam rotates, certain high pressure conditions are formed to cam rear, increase the suction effect of air-fuel mixture gas；This is new
Processing cost is low, easily realizes, will not additionally increase engine overall weight, and operational effect is stable.

Embodiment
As illustrated, a kind of two stroke engine with internal pressurization function, including cylinder sleeve 1, carburetor 2, crankcase
3rd, piston 4, connecting rod 5 and main shaft 6, a combustion chamber 7 is formed in cylinder sleeve 1, the combustion chamber 7 is by a reciprocating piston
4 are limited, and sealing ring 9 is cased with the piston 4, and wherein piston 4 is connected by a connecting rod 5 with the main shaft 6 in crankcase 3, main
Axle 6 is provided with cam 8 with the junction of connecting rod 5, and the drive shaft 6 of cam 8 that reciprocates through of piston 4 rotates, the one end of cam 8
It is connected with connecting rod 5, the other end is provided with towards the side of connecting rod 5 to be used to increase air inflow, axially inclined inclined-plane or curved surface, institute
State inclined-plane or curved surface be located at main shaft 6 both sides and incline direction on the contrary, the carburetor 2 is opened on the top of crankcase 3, and changes
The oil gas of oily device 2 enters Plane of rotation of the direction perpendicular to cam 8 of crankcase 3.
This is new at work, and gasoline and air enter after the processing of carburetor becomes air-fuel mixture gas arrives bent axle
The inner hollow chamber of case, wherein main shaft and cam rotate at a high speed, and the specific inclined-plane of cam or curved surface exist similar to turbine blade structure
During rotation, cam rear formed more High Voltage air-fuel mixture gas, contribute to air-fuel mixture gas to enter combustion chamber, increase into
Tolerance；The inclined-plane or curved surface design parameter of cam can be set as suitable specific ginseng according to engine model, discharge capacity, purposes etc.
Number, makes efficiency be optimal state.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe
Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example, still
Belong in the range of technical solutions of the utility model.
