The general engine has the advantages of reasonable structure, fine heat dissipation, high efficiency and the like.

Description

General purpose engine
Technical field
The utility model discloses a kind of general purpose engine, belong to technical field of engines, be applicable to ST177F-G ST182F-G ST188F-G series etc.
Background technique
At present, in traditional general purpose engine, because the restriction of its apparent size, its structure is all very compact, and therefore, the gap between each main body part is all very tight, it is very unreasonable to arrange as fuel tank, wind scooper etc., like this, tend to influence air inlet and radiating effect, and then influence the working life and the engine power of motor.
The model utility content
At the problems referred to above of prior art, the purpose of this utility model is to provide a kind of rational in infrastructure, good heat dissipation, general purpose engine that efficient is high.
The technological scheme that the utility model is taked for achieving the above object is as follows, a kind of general purpose engine, comprise that a crankcase body and one are connected on the crankcase body, be certain cylinder block with crankcase body to upper angle, it is characterized in that: the top that the silencing apparatus of band silencer cylinder is installed on cylinder block links to each other with the firing chamber, the corresponding silencing apparatus of empty filter compartment of terrain is arranged at an end position of cylinder block, following wind scooper, the side wind deflector, big cover of wind-guiding and stay cord cover be installed on respectively crankcase body and cylinder block around, on the outer side surface of crankcase body and cylinder block, be furnished with radiating fin, all be provided with the heatsink transverse sheet at the two ends up and down of radiating fin.
Of the present utility model further be provided with as follows:
Fuel tank is installed above crankcase body, and fuel tank is installed on the crankcase body by tank support, and an oil switch is installed on tank support, and the oil switch knob is installed on oil switch.
The beneficial effects of the utility model are as follows:
1, rationally adjusts the spacing of silencer cylinder and empty filter, in the external dimension that do not increase motor with reduce to have increased under the prerequisite of volume of fuel tank the volume of empty filter, power, the discharging of motor have been promoted, under the situation that keeps the original cylindrical shell of silencing apparatus, widen the spacing of silencer cylinder and empty filter, reduce the thermal radiation of silencing apparatus, thereby reduced the intake temperature of Carburetor empty filter.
2, removed the oil switch on the Carburetor, and individual oil switch has been installed on tank support, and on oil switch, the feel that the oil switch knob is used for increasing the circuit-breaker oil switch has been installed.So promptly be easy to open to close and remove fuel tank gasoline when right wing has been avoided conventional engines maintenance Carburetor, cylinder block again.
3, optimal design crankcase body, last wind scooper, the big cover of wind-guiding and stay cord cover.Increase the crankcase body heat diffusion area, respectively added the horizontal radiating fin of sheet, be used for air inducing on the one hand, be used for heat radiation on the one hand at the two ends up and down of crankcase body radiating fin.Because crankcase body lower half portion temperature is transmitted by the firing chamber, because the bang path radiating efficiency is strengthened, the temperature that is delivered to machine oil descends naturally, increases the crankcase body radiating efficiency.Wind scooper on the optimal design, make it better to be connected with crankcase body, the big cover of wind-guiding, avoid spilling cooling air, leak out in traditional common engine and carburetor place, thereby influence the stability of Carburetor work, new cooling system well addresses this problem, and cooling system comprises the big cover of wind-guiding, crankcase body, last wind scooper, following wind scooper, side wind scooper.Increase the air inlet cross section of stay cord cover, strengthened the air inflow in the unit time.The big cover air inducing of optimal design wind-guiding curve strengthens air inflow.These optimal design effectively reduce motor complete machine and oil temperature, prolong motor working life.
The utility model is described in further detail below in conjunction with annex map and embodiment.
