Abstract
The utility model relates to a small-sized single-cylinder four-stroke gasoline engine whose displacement below 50 ml. The small-sized single-cylinder four-stroke gasoline engine causes an air-inlet-outlet valve to be arranged on the top of a cylinder to solve the defects that gasoline engines with a horizontal valve has the disadvantages of no fluency of air inlet and outlet and insufficient efficacy, which causes the air to be entered and exhausted fluently and in time, and the initial moment explosive force of the small-sized single-cylinder four-stroke gasoline engine to be fully played and be used. The small-sized single-cylinder four-stroke gasoline engine only adopts a cam wheel to control the air entering and exhaust, and the utility model has the advantage of simple and reliable structure. The utility model can be used for the strengthening to bicycles and the collocation to cooling fans, and the utility model can be used for the requirements of minitype power source of normal or urgent fixed occasions such as power generation, lighting, water pumping, air compression, hydraulic raising, cutting off, disassembly, etc.
Description
The utility model relates to a kind of minitype gasoline motor, the particularly discharge capacity miniature single-cylinder four-stroke petrol engine below 50ml.
Present domestic minitype gasoline motor, be used for moped more, no matter be the motor of import, or homemade motor being two-stroke, is the outstanding person though wherein have Phoenix brand automobile-used Japanese Xiao Song motor and the Forever brand automobile-used Germany to stop to restrain this motor, but two stroke engine, will add machine oil in the fuel oil, it is insufficient to burn, the combustion gas heavy contamination, easy carbon deposit, the shortcoming that fuel availability is low, less economical, engine efficiency is low still exists.
Produced domestic first petrolic patent application of miniature single-cylinder four-stroke and mandate, the patent No. is: ZL93.22576.0 for this reason.
Though the patent of having authorized is a four stroke engine, overcome the intrinsic shortcoming of two stroke engine, but because air inlet and exhaust valve adopts the structure of flat placed type, determined combustion-chamber shape, be difficult to obtain desirable compression ratio and burning gallery, at the pressurized gas explosion time, a part of instantaneous explosion power can not directly act on the piston, make explosive power can not get sufficient utilization, and influence the performance of power.
The purpose of this utility model will provide a kind of improved miniature single-cylinder four-stroke petrol engine exactly, and it can improve the power of motor effectively.
The purpose of this utility model is achieved in that
With air inlet and exhaust valve, be located at cylinder head, deleted cylinder to the passage between the air valve, make intake and exhaust more happy and direct work as, secondly the firing chamber pressurized gas begins the instantaneous burst power of explosion time, can act on piston-top surface promptly, effectively, all sidedly, thereby make the most effective initial explosion power, can be brought into play to greatest extent.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the petrolic sectional drawing of miniature single-cylinder four-stroke that the utility model proposes.
Describe in detail according to engine operation details and the working condition thereof that the utility model proposes below in conjunction with Fig. 1.
This motor comprises spark plug 1, cylinder clothing 2, rocking arm set component 3, air inlet and exhaust valve 4, cylinder head 5, cylinder 6, piston 7, valve actuating push rod 8, idle rod 9, camshaft gear wheel 10, crankshaft gear 11, crankshaft ﹠ connecting 12, crankcase 13, single cam 14, camshaft 15.
When spark ignitor enters the compressed gasoline mixture body of combustion nozzle E, promptly produce blast, because the firing chamber adopts hemisphere to make combustion efficiency higher, in addition with air inlet and exhaust valve (4), be installed in the top of cylinder (6), thereby deleted the flat placed type air valve requisite cylinder to the passage between the air valve, make intake and exhaust more direct, reduce resistance and loss, and make cylinder begin the instantaneous explosion power of explosion time, can directly act on piston-top surface (flat placed type can only partly act on piston-top surface) comprehensively thus the most effective initial explosion power of motor can be brought into play to greatest extent, piston is subjected to the effect of explosive power, pump, pass through connecting rod, the drive bent axle rotates, traditional four stroke engine is valve of a cam control, and the utility model adopts a cam, by idle rod (9), valve promotes (8), and rocking arm set component (3) is swung to respectively in good time and promoted to open or close air inlet and exhaust valve (4), adopt single cam structure simply compact, timing is correct, and cam shown in the figure is to be in intake and exhaust overlapping angle position, and piston this moment (7) is positioned at the cylinder top dead center.
The utility model not only can be used for the usefulness that bicycle is made power-assist, and as long as the configuration cooling fan, also can be used for the power source needs of the occasion that the jacking, orcible entry etc. of generating, illumination, ventilation, pump water, small-sized air compressor, the hydraulic power supply of fixing or mobile occasion meet an urgent need, speedily carry out rescue work.
Claims (4)
1, a kind of by spark plug, cylinder head, cylinder cover, cylinder body, piston, bent axle, connecting rod, the single cylinder petrol engine of composition, holding is not the miniature single-cylinder four-stroke petrol engine of discharge capacity below 50ml, it is characterized in that; There is a camshaft [15] parallel with bent axle crankcase [13] lining, on bent axle and the protruding axle crankshaft gear [11] and camshaft gear wheel [10] are housed respectively, and the timing gear that partner that are meshing with each other, cam [14] is arranged on the camshaft, idle rod [9] is arranged on it, valve actuating push rod [8] is arranged on the idle rod, and the top of valve actuating push rod and rocking arm are formed component [3] hinge joint, and intake and exhaust valve [4] is arranged at the bottom of rocking arm set component.
2, according to the described miniature single-cylinder four-stroke petrol engine of claim l, it is characterized in that; Intake and exhaust valve [4] is the overhead type structure.
3, motor according to claim 1 is characterized in that; A cam [14] only is housed on the camshaft [15].
