Description
The utility model relates to two-stroke gasoline engine.
Traditional two-stroke gasoline engine exists the following problem: the time that only is equivalent to 130 ° of crank angles in (1) its per operation cycle its period of combustion, the time that is equivalent to 180 ° of crank angles compared with four-stroke gasoline engine period of combustion, its fuel oil almost lacked for 1/3 period of combustion, so can not just have been drained after the perfect combustion; (2) ignition magneto power is generally 4～6 volts, and its spark ignition area and temperature are not enough, and fuel oil is difficult at rapid after-flame of short period; (3) the free exhaust phase is short, the time that is equivalent to 12 °～20 ° of crank angles, (Japanese is the time of 23 °～24 ° of crank angles the best free exhaust phase) so that its waste gas after burning is got rid of is unclean, is trapped in the cylinder sleeve the mixed and influence burning work doing efficiency with the combustion gas of new inspiration.Above-mentioned various reasons, it is big to have caused the waste of two-stroke gasoline engine fuel oil to consume, and the power of acting is low, influences its application and development.
The purpose of this utility model be to provide that a kind of compression ratio height, igniting are swift and violent to the public, burning fully, the clean energy-conservation two-stroke gasoline engine of exhaust.
The utility model contains parts such as cylinder shell, suction tude, intake valve, outlet pipe, exhaust valve, cylinder sleeve, cylinder cap, spark plug, piston, crank, crankshaft, crank box and ignition magneto.Its cylinder shell both sides are equipped with suction tude and outlet pipe respectively; Suit cylinder sleeve in the cylinder shell, and cylinder sleeve has the inlet and outlet hole corresponding to air inlet and exhaust piper place on the cylinder shell; The cylinder sleeve cylinder cap that is stamped suitable for reading is equipped with spark plug in the cylinder cap center hole; The cylinder sleeve end opening is connected with crank box; Cylinder sleeve is equipped with piston inside, and piston is connected with crank downwards, and the crank lower end is positioned at crank box and is connecting crankshaft; Crankshaft stretches out crank box and is connecting clutch and magnetogenerator outward.The shape and structure and the annexation of above-mentioned component shape structure and annexation and existing two-stroke gasoline engine corresponding part are basic identical, different is: it is amid a sharp increase that inlet hole is lower than the spacing of exhaust port on (1) its cylinder sleeve, original cylinder sleeve of engine inlet and outlet hole initial line location gap is 3mm, and it is 8～8.5mm that this cylinder sleeve of engine inlet and outlet hole initial line location gap is drawn back; Its suction port angle that is inclined upwardly is increased to 45 °～60 ° by original 30 °～45 °.(2) original engine cylinder shell has only in the suction tude of a side intake valve is housed, and there is not exhaust valve in the outlet pipe of opposite side, cause when air-breathing fuel oil-gas to run away easily from outlet pipe, intake valve not only is equipped with in the suction tude in this engine cylinder shell both sides, and in its outlet pipe an exhaust valve also is housed.(3) use high-power ignition magneto instead, strengthen ignition magneto power, (400～500 rev/mins) bring up to 13 volts～18 volts by original 4～6 volts during its power slow-speed of revolution.(4) base frame has shortened 2mm height under the cylinder cap, its combustion chamber volume than original volume-diminished about 1/7.
The utlity model has following advantage: 1,, its plug ignition area is strengthened and the temperature raising, fuel oil-gas is burnt to the greatest extent in the time that is equivalent to 130 ° of crank angles because ignition magneto power strengthens; 2, because the inlet hole angle of inclination is strengthened, firing chamber, its fuel oil-gas easier arrival cylinder top is in order to burning; 3, because exhaust valve is equipped with at the exhaust port place, can not only prevent from like this to become flat from outlet pipe at pressure of inspiration(Pi) compression process intermediate fuel oil gas; Simultaneously, its inlet hole exhaust port is relatively opened more down downwards, so just increased the free exhaust phase, made its exhaust cycle bring up to time of 25 °～35 ° of crank angles, guaranteed that cylinder waste gas row's is clean by the original time that is equivalent to 12 °～20 ° of crank angles; 4, because combustion chamber volume has been dwindled about 1/7, and its compression ratio was brought up to 1: 7 by 1: 6, the mixed gas uniformity is improved, more easy firing is complete.Above-mentioned four aspects are energy efficient greatly, and 100 kilometers oil consumption are dropped to about 1.1 liters by original 2.5～3 liters, can reduce exhaust emission pollution simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Fig. 1 shape and structure schematic representation of the present utility model
As shown in Figure 1, the utility model contains parts such as cylinder shell 1, suction tude 10, intake valve 9, outlet pipe 2, exhaust valve 3, cylinder sleeve 5, cylinder cap 6, spark plug 7, piston 11, crank 12, crankshaft 13, crank box 14 and ignition magneto.Cylinder shell 1 both sides are equipped with suction tude 10 and outlet pipe 2 respectively; Suit cylinder sleeve 5 in the cylinder shell, and the air inlet and exhaust piper place has inlet and outlet hole 8 and 4 on the cylinder sleeve respective cylinder shell; The cylinder sleeve cylinder cap 6 that is stamped suitable for reading is equipped with spark plug 7 in the cylinder cap center hole, the cylinder sleeve end opening is connected with crank box 14; Cylinder sleeve is equipped with piston 11 inside, and piston is connected with crank 12 downwards, and the crank lower end is positioned at crank box and is connecting crankshaft 13; Crankshaft stretches out crank box and connects clutch and magnetogenerator.The shape and structure and the annexation of above-mentioned component shape structure and annexation and existing two-stroke gasoline engine corresponding part are basic identical, different is: it is amid a sharp increase that inlet hole 8 initial lines are lower than the spacing of exhaust port 4 initial lines on (1) its cylinder sleeve, both upper-lower position spacings originally are 3mm, and both upper-lower position spacings of this motor are 8～8.5mm; Its suction port angle that is inclined upwardly is increased to 45 °～60 ° by original 30 °～45 °.(2) original engine cylinder shell has only in the suction tude of a side intake valve is housed, and does not have exhaust valve in the outlet pipe of opposite side; Intake valve 9 is equipped with for 10 li in this engine cylinder shell both sides not only suction tude, and its outlet pipe also is equipped with an exhaust valve 3 for 2 li.Because the existence of this valve, when air-breathing, it can be blocked exhaust port and not allow the fuel oil-gas leakage efflux; When combustion explosion, because its realization exhaust that can be open again of pressure; (3) use high-power ignition magneto 15 instead, strengthen ignition magneto power, its power is brought up to 13 volts～18 volts by original 4～6 volts, and spark plug 7 ignition areas strengthen and temperature raises like this, so that guarantee can the after-flame fuel oil-gas in the time that is equivalent to 130 ° of crank angles.(4) 6 times base frames of its cylinder cap have shortened the 2mm height, and its combustion chamber volume has then been dwindled about 1/7, and its compression ratio was brought up to 1: 7 by original 1: 6, and the mixed gas uniformity is improved, and more easy firing is complete.
