Abstract
The gasoline engine with two horizontally and oppositely set cylinders includes upper and lower engine bodies, cylinders, spark plug, piston assembly, piston ring, crankshaft link assembly, leaf valve assembly and carburetor. The crankshaft link assembly is set inside the crankshaft box comprising the upper and the lower engine bodies, the right and the left cylinders are set horizontally on two sides of the crankshaft box and are provided with separated exhaust pipes, the piston assembly is connected to the crankshaft link assembly and set inside the right and the left cylinders, and the carburetor is fixed on the crankshaft box via the leaf valve and has fixed gas intake seat. With the said structure, the gasoline engine of cylinder diameter of 33 mm has displacement of 48 cc, maximum power up to 3.1 kw in 8500 rpm rotation speed and rotation speed stability within 1 %.
Description
Technical field
The present invention relates to a kind of petrol engine, particularly a kind of small capacity double cylinder gasoline engine.
Background technique
At present, general small capacity double cylinder gasoline engine structure generally has two kinds of V-type double-cylinder gasoline engine and abreast-type double-cylinder gasoline engines, exist following defective: the one, because piston is not done the symmetric motion of relative crankshaft center at grade, can not offset interaction force, cause the petrol engine vibration big, consumed the power of petrol engine virtually, power consumption is big, utilization ratio is low; Two is that two cylinders are not worked simultaneously, and petrol engine rotational speed stability is poor relatively; The 3rd, need to be equipped with two Carburetors, and, to have increased the production difficulty the coherence request height of two Carburetors, improved cost of production; The 4th, volume is big, installation is inconvenient.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing double-cylinder gasoline engine exists, problem to be solved by this invention provide a kind of simple and compact for structure, thermal power is high, speed stability good, flat opposed double-cylinder gasoline engine easy for installation.The technical solution adopted for the present invention to solve the technical problems comprises upper and lower body, cylinder block, spark plug, piston assembly, piston ring, crankshaft rod assembly, reed valve ASSY, Carburetor, described crankshaft rod assembly is arranged in the crankcase of upper and lower organization, left and right cylinder block is horizontally set on the crankcase both sides of upper and lower organization, piston assembly is connected connecting rod one end of crankshaft rod assembly and is arranged in the left and right cylinder block, and Carburetor is fixedly connected on another plane of crankcase of upper and lower organization by reed valve ASSY.
For the ease of toxic emission, be respectively equipped with outlet pipe on the described left and right cylinder block.
For the ease of air inlet, be fixed with air inlet seat on the described Carburetor.
After adopting said structure, crankshaft center symmetric motion relatively in the two-piston while left and right sides cylinder block at grade the vibration force of its generation is cancelled out each other, so this machine vibration is little, efficient is high, and speed stability is good; Because air inlet seat, Carburetor and reed valve ASSY are set directly on the crankcase of upper and lower organization, so this machine only need be equipped with a Carburetor again; Have rational in infrastructure, volume is little, easy for installation, thermal power is high, good stability, low cost and other advantages.

Embodiment
Illustrated in figures 1 and 2, specific embodiments for a kind of flat opposed double-cylinder gasoline engine of the present invention, it comprises, lower body 1,2, cylinder block 7, spark plug 6, piston assembly 4, piston ring 3, crankshaft rod assembly 5, reed valve ASSY 9, Carburetor 11, described crankshaft rod assembly 5 is arranged on, lower body 1, in 2 crankcases of forming, a left side, right cylinder block 7 is horizontally set on, lower body 1, the 2 crankcase both sides of forming, piston assembly 4 is connected connecting rod one end of crankshaft rod assembly 5 and is arranged on a left side, in the right cylinder block 7, a left side, be respectively equipped with outlet pipe 8 on the right cylinder block 7, Carburetor 11 is fixedly connected on by reed valve ASSY 9, lower body 1, on 2 another planes of crankcase of forming, be fixed with air inlet seat 10 on the Carburetor 11.
Working procedure of the present invention is as follows, air enters from air inlet seat 10, oil gas mixed aerosol in Carburetor 11, piston 4 kinetic variation in pressure controls in the crankcase enclosed space that the reed Push And Release of reed valve ASSY 9 is made up of upper and lower body 1,2, about fuel-air mixture enters into respectively again in two cylinder blocks 7, crankshaft rod assembly 5 drives left and right piston assembly 4 work and finishes air inlet, compression, acting and four processes of exhaust of left and right two cylinder blocks 7, thereby finishes petrol engine work.Through this machine is tested, when cylinder diameter was 33mm, discharge capacity was 48c c, and peak output can reach 3.1kw/8500rpm, and the stabilization of speed rate is the best petrol engine of domestic petrol engine medium speed stability in 1%.
