Abstract
The utility model relates to an air valve type two-stroke internal combustion engine. An exhaust door is arranged on the top of an air cylinder. The air valve type two-stroke internal combustion engine is not provided with an exhaust port. Scavenging ports with the same height are evenly distributed on the circumference of a cylinder wall. A piston ring adopts a single-interface zero-clearance interlacing structure. The utility model has the advantages of fuel oil saving of 20-30%, power increase of 25-30%, and reduction of environmental pollution of noise and waste gas. The structure of the utility model is suitable for internal combustion engines with various different numbers of revolutions, any discharge and power.
Description
The utility model belongs to internal combustion (IC) Engine Design and manufacturing technology field.
The internal-combustion engine of domestic and international various models is piston type at present.Comprising two-stroke and two kinds of types of four-stroke.The former stable working, its shortcoming are that fuel consumption is big, the noise that sends and the exhaust emission pollution environment of discharge; The latter is consumed energy greatly, efficient is low, work is not steady.
The purpose of this utility model is, a kind of novel structure, energy-efficient air gate type two stroke IC engine are provided.
Structure of the present utility model as shown in the figure.Form by crankcase, cylinder block, cylinder head, crankshaft-link rod and driving mechanism.Its inventive point is:
1, cylinder head is equipped with exhaust valve 19.Its effect is, the strength that effluxes waste gas is evenly concentrated, airflow direction vertically, does not produce eddy current, and toxic emission is more thorough.Air-flow strength zero deflection, fresh burning mixture can not run away with waste gas.The quantity of exhaust valve is decided according to need.
2, there is not relief opening on the cylinder inner wall, and uniform contour four scavenging ports 10 that have only.Its effect enters cylinder with being to make inflammable mixture high concentration gross area, direct current advances.And the effect that outwards helps waste discharge gas arranged.
3, piston ring is the wrong cut piston ring 7 of single port zero-clearance.Its effect is a good seal performance, and the high-temp waste gas after inflammable mixture and the burning can not flow into crankcase, introduce thermal distortion.And can reduce the erosion of waste gas to lubricant oil.Use this piston ring can save fuel oil 10%, and make the power moment of torsion of motor improve 8%.
Working principle of the present utility model is:
When compressed inflammable mixture, igniting, outburst, expansion working, promotion piston 8 move down, during 132 ° of crank angles, by connecting rod 13, bent axle 15, gear 23, chain 21, timing gear 17, camshaft 8, cam 1, unlatching exhaust valve 19, at this moment, the waste gas after the work done begins to efflux.
Bent axle 15 continues rotation, and its corner is in the time of 216 °, and scavenging port 10 and relief opening 19 are closed simultaneously, and inflammable mixture enters compressive state.
Bent axle 15 continues rotation, and its corner is in the time of 360 °, and piston 8 moves to top dead center on, has finished a work cycle.By that analogy.
Manufacturing process of the present utility model does not have big difference with the manufacturing process of existing similar internal-combustion engine, just needs by structural design manufacturing of the present utility model.
Experimental results show that: the utility model can increase power 25～35%, fuel-economizing 20～30% simultaneously.Press the utility model structure in the experiment, reequiped an internal-combustion engine that discharge capacity is 100CC, the result reaches the merit that discharge capacity 125CC internal-combustion engine is done.The structure of this machine is applicable to the internal-combustion engine of the various power of various revolutions.
The advantage of air gate type two stroke IC engine is: oil consumption is low, and can improve power, and noise is low, and the degree of exhaust emission pollution environment is slight.
