Abstract
The utility model relates to a distributor for intake of a two-stroke petrol engine. The utility model is provide with a back cover of the distributor which is connected with a box body of the engine or a gas inlet of a cylinder, a front cover of the distributor, a valve sheet of the distributor, a rotating shaft with a key gear and a flexible shaft which is connected with a crankshaft of the engine. Due to the adoption that two through holes are arranged on the front cover of the distributor, one through hole passes through a carburetor, the other through hole passes through the atmosphere or an air filter, in the process of the engine working, fuel can be sufficiently burned, the work efficiency of the engine is increased, and the effect of fuel saving is good.
Description
The utility model relates to the fuel-economizing settling-discharging device on the two-stroke gasoline engine in the dynamic power machine, a kind of two-stroke gasoline engine air inlet distributor.
At present, two-stroke gasoline engine adopts crankcase loop scavenging mode more, and its characteristics are: the crankshaft rotating tour, finish a work cycle, piston sucks crankcase to top dead center inflammable mixture in service through Carburetor by lower dead center, and the interior inflammable mixture of cylinder is by Piston Compression simultaneously.The burning back piston is moved to the lower dead center work done by top dead center, simultaneously inflammable mixture in the compression crankshaft case.When opening relief opening and scavenging port, finishes in piston gas exchange process in the cylinder.In gas exchange process, the part of exhaust gas inside cylinder is to push the exhaust mouth by the inflammable mixture that scavenging port flows out, the part inflammable mixture unavoidably can together be discharged with waste gas and be caused fuel loss outside the cylinder in the high engine speeds running, the part residual gas of staying simultaneously in the cylinder has influenced next circuit firing effect (coefficient of residual gas 0.25-0.30 in the general cylinder), under idling operation, the residual gas amount is bigger in the cylinder, influence normal combustion, the engine fire rate is higher, is directed at the engine emission degradation.
The purpose of this utility model is a kind of two-stroke gasoline engine air inlet distributor of design, in engine working process, replace air supply and inflammable mixture in cylinder, form independent air ventilation cycle and burning work done circulation, greatly improve ventilation state and combustion condition, can improve efficiency of engine.
The purpose of this utility model is realized by following technological scheme: described two-stroke gasoline engine air inlet dispensing arrangement consists of: have the distributor bonnet 5 that links to each other with engine housing or cylinder body air inlet position, distributor protecgulum 4, the distributor valve block 3 of flat-shaped sector structure, key-toothed rotatingshaft 2, one end of rotating shaft 2 is sleeved on the distributor valve block 3, the other end fixes with driving snake and connects, driving snake 1 links with engine crankshaft, and can be by key tooth rotating shaft driven rotary with 1: 2 speed ratio drive key tooth rotating shaft 2 distributor valve blocks 3, distributor protecgulum 4 is provided with two through holes, one is connected with Carburetor, and another links to each other with atmosphere or air-strainer.When motor is in the air ventilation cycle, distribute valve block 3 to open the air stream through holes, close with Carburetor joins and mix pore, when motor is in burning work done circulation time, distribute valve block 3 to open the mixed airflow through holes, close air hole.
The utlity model has following advantage:
Since at the air inlet position of two-stroke gasoline engine cylinder body or engine housing device the air inlet distributor, fully reasonable distribution air inlet, discharge amount of exhaust gas is obviously reduced, mixed gas fully burns, compared with prior art, under power is not less than situation with the discharge capacity four-stroke gasoline engine, efficiency of engine is improved greatly, oil-saving effect is remarkable, can make minimum specific fuel consumption near the four-stroke gasoline engine level.
Below in conjunction with the description of drawings specific embodiment of the utility model:
Fig. 1 is a two-stroke gasoline engine air inlet dispensing arrangement schematic representation.
As shown in the figure, 1-driving snake, the rotating shaft of 2-band key tooth, the flat-shaped fan-shaped valve block of 3-, 4-distributor protecgulum, 5-distributor bonnet.Driving snake 1 links to each other with engine crankshaft, bent axle drive driving snake 1 drives key tooth rotating shaft 2 with 1: 2 speed ratio, distribute valve block 3 under the drive of key tooth rotating shaft 2, to rotate, distributor protecgulum 4 is provided with two through holes, one and Carburetor join, one communicates with atmosphere, and distributor bonnet and engine housing or cylinder body air inlet position join.When motor is in the air ventilation cycle, distribute valve block 3 to open the air stream through holes, close with Carburetor joins and mix pore, when being in burning work done circulation time, distribute valve block 3 to open the mixed airflow through holes, close air hole.Distributor is accurately constantly finished the alternately work of air supply and inflammable mixture in cylinder under the effect of crank angle.
