The transmission ratio of the crankshaft to the circular hub is 3:1. One gear of the tail of the internal combustion engine is fastened on the rear cover. The other two gears are respectively arranged on the circular hub and the crankshaft. Gaps are formed between the three small cylinders and the inner wall of the drum body, and two to four sealing devices are arranged in the gaps. The internal combustion engine has the advantages of small volume, big horsepower, low oil consumption, low manufacturing cost, high efficiency, simple manufacture and convenient repair.

Description

Circular gas valve-free diesel internal combustion engine

The present invention relates to a kind of internal-combustion engine arrangement, this device both can be used for various automobiles, on tractor and the motorcycle, also can be used for baby plane, on the naval vessels as diesel oil or gasoline-engine driven machine.

Because traditional four stroke engine structure more complicated, its intake efficiency is low, and frictional loss is serious, and noise is big.Therefore, have many technological schemes to propose improved imagination, for example, Chinese patent CN1083172A number about relating to a kind of motor in " four-stroke engine with rotary cylinder ", its cylinder cap is a hollow cylinder, be provided with bent axle at gyration center, the side is provided with the inlet and outlet mouth, and cylinder body is connected on the bent axle, and be divided into three cylinders, this cylinder is that the center is radial arrangement with the bent axle, in establish piston and linkage mechanism, bent axle is 3 to the cylinder body velocity ratio.This motor simple in structure is owing to take the linkage mechanism of traditional type to implement certain degree of difficulty, sometimes even the phenomenon that can bump.

Task of the present invention is that a kind of circular gas valve-free diesel internal combustion engine will be provided, and its volume is little, and horsepower is big, and oil consumption is few, and cost is low, and the efficient height is made simply, and is easy to maintenance, can give various machine layout power engines, becomes seriation power product.

Task of the present invention is to finish in such a way.This just round gas valve-free diesel internal combustion engine is to adopt combustion gas outburst mechanical motion power, its distribution mode is that four strokes are revolving, it has cancelled air inlet, drain tap mechanism, hub rotation mode and greatly just round cylinder diameter seal arrangement in adopting, it has thoroughly changed traditional case structure in upright arrangement, the just round formula of cylinder of just justifying inside and outside the employing.A kind of all-metal, inside and outside all present positive circular combination and mechanically be divided into three layers, outermost surface is immobilizing foundation spare (a drum body), the center is high speed rotating part (bent axle), the mesosphere is slow rotation part (a circle hub), the little cylinder of radiation of three equalizations of circle distribution of circle hub, a short piston is respectively put in the inside of cylinder, short piston is connected on the crank throw face at bent axle middle part by the wrist pin at middle part and the utmost point palm that is enclosed within on the wrist pin, do slip, swing and reciprocal three kinds of motions, the rotating ratio of bent axle and circle hub is 3: 1.Afterbody at device is equipped with " four-journey motion slide teeth wheels ", and 3: 1 accuracy rate is finished by the slide teeth wheels.Three little cylinder port distribute in the periphery of circle hub, it leaves big gap when slow-speed and between the inner chamber of outer fixing spare (drum body), drag leakage from this gap for preventing combustion gas, periphery at little cylinder mouth is provided with the horizontal and vertical interlaced sealing network in 2-4 road, guarantee the proper functioning of outburst combustion gas, reach the purpose of sending horsepower.

The present invention is further elaborated below in conjunction with accompanying drawing.
