Abstract

The engine is used for driving of transport machines and assemblies. It is reliable and can work in a stable manner using poor mixtures of all liquid fuels used so far, and gas. The four-stroke rotorinternal combustion engine comprises a stator (1) with covers, on which the following rest in a concentric manner: housing (4) - tube with covers (8, 9), eccentric crankshaft having the same eccentricity of the crank where are fitted, across an intermediate wall (7), two pistons: a pressure (13) and rotor (14), non-cylindrical, double acting on one plane, and their adjacent volumes have gas connection by means of a valve (20). Thence, in one direction the pressure fuel mixture is injected in the forced not discharged waste gases of high temperature in the combustion chamber (19) where they burn out. In the lower quarter travel, pistons (13, 14) open windows (17) from where their intake the mixture and discharge the waste gases. Housing (4) and crankshaft (10) also have kinematic connection with gear ratio 1:2.

Description

(54) FOUR-stroke internal combustion engine

Technical field

The invention relates to a four-stroke rotary internal combustion engine that can be used to drive transport machines and installations.

BACKGROUND OF THE INVENTION

The engine structure offered is close to those of class FO1C1 / 34, for example DE 2438189, in which the operating chambers are formed by an eccentrically rotating disc rotor and a twice slower rotating concentric housing with a cavity that the rotor disk would translate into as a translation outline. Typical of such structures are low functional suitability and reliability, which is sufficient not to be put into practice.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a functional and reliable four stroke internal combustion engine. This is achieved by a rotary internal combustion engine consisting of a stator and a tube with lids on which the lugs are supported: coaxially with the stator, the lids of the pipe lenght, in which two bushings with a central disc with a central disc are contacted longitudinally and in series an opening pressed at both ends by the front between the covers of the housing; eccentric to the stator, the main crankshaft bearings having the same eccentricity of the crankshaft to which they bear in series and contacting, through the front sealing segments, with the intermediate disk and with one of the housing covers, two double acting in one plane of the housing of the piston - injection and working. Inside each sleeve, diametrically, two cut-off sections are secured in a section along the arc, through which a gas cavity is formed between each cut-out and the casing, for the window windows of the cut-outs opening about the lower quarter of the course of the pistons from the intermediate plate to intake and exhaust systems, respectively. The piston cross-sectional shape of the piston allows translation across the sections of four crankshaft eccentricities up to the arch stop with the bushings. There is one combustion chamber in the two faces of the piston and the adjacent piston spaces have a gas connection opened by a pressure valve less than the combustion air mixture in the discharge section, one-way to the combustion chamber. There is a 2: 1 gear ratio between the crankshaft and one of the housing covers.

The four-stroke internal combustion engine has good sealing of the workspaces, which determines its functional fitness10, and relatively low compression and friction forces for one crankshaft rotation between the moving parts, which determines the increased reliability.

Examples of carrying out the invention

An four-stroke rotary internal combustion engine 25 in one embodiment consists of a stator 1 with lids 2 and 3, on which lids 2 and 3 camp: coaxially with a stator 1 tube - housing 4, in which longitudinally and sequentially contact with it through the opening two bushings 5 and 6 with intermediate disc 7 pressed 30 between covers 8 and 9; eccentric to the stator 1, the main bearing of the crankshaft 10 having the same eccentricity of the casting, to which they bear consecutively and contacting by means of the front sealing segments 11, pressed out from the pins 35 by the wires 12, with the intermediate disk 7 and with one of the covers of the housing 4 two double acting in one plane of the casing 4 pistons-discharge 13 and working 14. Internally to each sleeve 5 and 6, diametrically, two pieces-sections 15 are secured in section along the arc, 40 through which a gas cavity is formed between them. the windows 17 of the sections 15, open ryani around the lower quarter of the stroke of the pistons 13,14 of the intermediate plate 18 to the intake and exhaust systems, respectively. The transverse to the housing 4 45 of the piston shape 13 and 14 allows translation of the detail sections 15 at a distance by the quadruple eccentricity of the crankshaft 10 to the arch stop with the bushes 5.6. Both pistons 14 have one combustion chamber 19, and above the piston 50 spaces there is a gas connection adjacent one way to the combustion chamber 19 of a valve 20 at a pressure of less than self-ignition 2 than the combustion mixture. In the cover 2 is housed an oil pump with internal engagement, driven by a crankshaft 10, the wheel with internal teeth having external ones 21, which are engaged with the inner teeth of the hub 8, transmitting the ratio of the crankshaft 10 with the casing 4 equal to 2: 1.

Application of the invention

When operating in the described engine, a vacuum is created behind the discharge piston 13 about its translation direction relative to the housing 4 and a working process is created behind the piston 14, which processes take place until the windows 17 are opened when the fuel mixture is sucked in and ejected. the exhaust gases. Before the piston 13 and before the piston 14, after closing the windows 17, the suction of the suction fuel mixture and the uncharged exhausts takes place, until the injection through the valve 20 of the fuel mixture proceeds from about 20 ° to the most extreme position of the pistons 13 , 14, in the combustion chamber, where it comes into contact with the hot exhaust gas, it ignites.
