Abstract
The utility model provides a two -stroke -cycle engine's waste gas turbocharging system places booster (1) in the cylinder row gas port position of engine, sets up an inside impeller (2) in the inside of booster (1), sets up an outside impeller again in the outside of booster (1), and inside impeller (2) and outside impeller are connected. The utility model discloses outside impeller drives fresh air and produces the air current, flows in the carburetor throat, increases the carburetor direction pressure that admits air, improves the intake pressure of engine.
Description
Technical field
The utility model relates to graden machine two stroke engine, especially a kind of exhaust gas system of two stroke engine.
Background technique
On the two stroke engine of gardens, adopt naturally aspirated engine both at home and abroad more, emission control many employings ternary or unit catalyzer conversion toxic emission value, discharge value basic controlling below 50cc discharge capacity is at HC-NOX < 50g/kw.h, 50CC < discharge capacity < 80CC discharge value HC-NOX < about 72g/kw.h, catalyst turnover could will control in scope by motor substantially more than 50%, more high-engine burden is heavier for conversion ratio, and temperature is higher.
In order to solve the problem, hereby the utility model is proposed.
Summary of the invention
The purpose of this utility model, is the exhaust gas system providing a kind of two stroke engine.
In order to realize these objects, adopt following technological scheme:
A kind of exhaust gas system of two stroke engine, pressurized machine 1 is placed at the cylinder vent position of motor, arrange an internal impeller 2 in the inside of pressurized machine 1, arrange an outside impeller again in the outside of pressurized machine 1, internal impeller 2 is connected with outside impeller.
Advantageous Effects: the outside impeller of the utility model drives fresh air to produce air-flow, flows into carburetor throat, increases carburetor air directional pressure, improve the suction pressure of motor.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
Fig. 2 is the utility model impeller 2 structural drawing.
When Fig. 3 is utility model works, air-flow moves towards schematic diagram.
Be below the mark of accompanying drawing in the present invention, illustrated by accompanying drawing and corresponding mark, clearly can understand the utility model.
Increase device 1, impeller 2, flywheel 3, air intake pipe 4
Embodiment
Now the utility model is described in more detail by reference to the accompanying drawings.
With reference to shown in Fig. 1-2, the utility model provides a kind of exhaust gas system of two stroke engine, pressurized machine 1 is placed at the cylinder vent position of motor, an internal impeller 2 is set in the inside of pressurized machine 1, an outside impeller is set in the outside of pressurized machine 1 again, do not draw in figure, internal impeller 2 is connected with outside impeller.
With reference to Fig. 3, when engine start rear engine vent produces exhaust pressure internal impeller 2 during use, internal impeller 2 drives outside wheel rotation, gas is through flywheel 3, discharged by air intake pipe 4, outside impeller drives fresh air to produce air-flow, flows into carburetor throat, increase carburetor air directional pressure, improve the suction pressure of motor.
Although disclosed the utility model by above embodiment, protection domain of the present utility model is not limited to this, all belongs to protection domain of the present utility model not departing from the equivalent replacement under the utility model design condition.
