During the past few years there have been numerus types of internal combustion engines with rotating pistons of different shapes serving various purposes.
However all these engines with rotating pistons have some things in common: an especially simple construction, the possibility of balancing the rotating piston, with high power and high revolutions per minute, but none of the proposed constructions have progressed beyond the prototype stage.
The aim of the invention is to develop the construction of internal combustion engines with a piston that rotates or moves inside the cylinder. The task of the invention is related to the kinetics of the piston and the blades in the internal combustion engine working area, with the goal of improving the contrivance.
Further aims and advantages of this invention will partly be shown in the following description and will partly be learned through the use of the invention.
The internal combustion engines using this invention will incorporate a cylindrical casing with a vortical chamber for the combustion of carbureted mixture and a suction and exhaust ducts.
The centre of the cylinder which is also the centre of rotation there is a crankshaft with a circular piston which, with its construction, can change the touching surface of the piston volume with the inner wall ouf de crankcase by means of a blade inside the piston which is fixed to the cylinder crankcase plate, so that the wall of the piston volume by a twist of the crankshaft touches and at the same time skids the inner wall of the crankcase.
The working space in this invention is situated above the outer radius of the piston and the inner radius of the cylinder and is divided into chambers by the blades. The volume of each chamber is related to the blades and it changes all the time as a result of the rotation of the piston along the elbow of the crankshaft.
Lubrication achieved by means of a pump from the oil-sump may be of the typical standard, compressing the oil into the centre of the piston area, and by special collectors the oil is returned to the oil-sump.
In another variant of the internal combustion engine after modification on the piston and cylinder crankshafl it is possible to construct this engine where a mixture of air, petrol and oil provide lubrication.
The drawings included in this description illustrate the performance of this invention and help explain its basic principles, Drawings la, Ib, Ic, and I d ill ustrate the working cycle of the engine in one twist of the crankshaft.
Drawing 2 shows one of at least two cylinder crankcase plates of the engine.
Drawing 3 shows the piston of the proposed combustion engine.
Drawing 4 shows indications for half sections (A) and (B).
Drawing 5 shows half section (A).
Drawing 6 shows half section (B).
Drawing 7 shows construction modification of the proposed engine to the inlet manifold and refers to marks of quarter section (A).
Drawing 8 shows quarter section (A) of the modified construction on the piston and engine plate with regard to the inlet manifolds.
Drawings la, lb, Ic and Id show the crankcase and the piston position with its blades, and the way the proposed internal combustion engine functions dring one full twist of the crankshaft. Piston 2 shown in drawing 1 a of the circular section rotates with its axis against the elbow of crankshaft 12 and at the same time it skids with its volume against the inside surface of the crankcase 1. Such kinematics of the piston is resulted by blade 4 shown in drawing Ib which has its fixed centre at point 5. Blade 4 together with piston 2 stipulates blade 6 movement along groove 7, thus providing a continual volume change of the chambers (A), (B), (C) and (D). The fuelling of the engine goes through a channel in chamber (A), in chamber (C), the combusted gases expand and chamber (D) exhausts the combusted gases.
Further, because of the crankshaft 3 rotation, shown in drawing lc, the exchange of fuel mixture in the vortical chamber 9 takes place, piston 2 together with blades 4 and 6 exchange the chambers and their volume.
Drawing 1 d shows chamber (A :) at the beginning of priming, chamber (B) at the end of compression and chamber (D) at the beginning of exhaust.
The circular arch 8 on crankcase in front of vortical chamber 9, is designed with its centre at axis 5 of the blade 4 movement. The mixture ignition equipment 10 or the fuel injection equipment has to be built into vortical chamber 9.
Drawing 2 shows one of at least two engine plates 11 and indicates the required axis rotation and the axis of the movement of the elements inside the crankcase. The crankshaft rotates in the centre of crankcase 3. The piston rotates along crankshaft 12. and at the same time it skids against the inner wall of the crankcase 1. The axis of the fixed blade movement is at point 5, and it is situated along the radius between the centre of the crankcase 3 and the centre of the channel of vortical chamber 13. The distance from the centre of the piston 12 to the axis of the blade 5 movement has to be smaller than the radius of the piston, the same goes for the blade that moves along groove 7.
Increasing or decreasing the piston radius in relation to cylinder crankcase radius, the distance between the blade centres has to be adjusted. Oil collectors 14 illustrate the possibility ofretur-ning the oil to the oil-sump 15.
Drawing 3 shows the piston of circular section with openings 16 and 17 for the blades. At opening 16 there is a circular arch 18 which corresponds geometrically with the circular arch on the inner wall of the crankcase in front of the vortical chamber.
Drawings 4J and 6 illustrate the so far described performance of the internal
combustion engine, its aim being more precise possibilities of such engine construction.
Drawing 5 section (A) shows the centre of movement 5 of blade 4 as well as movement along groove 7 of blade 6.
Also, drawing 6 section (B) shows crankcase 1, engine plates 11 crankshaft 3, piston 2 and the lubrication mechanism 19 with oil collectors 14.
The proposed internal combustion engine with this construction would have all four strokes: intake, compression, expansion and exhaust stroke in one twist of the crankshaft. This engine could be applied to machines that require light weight engines, high power and high revolutions per minute.
Drawings 7 and 8 show an alternat construction of the proposed internal l combustion engine where the main modifications are in the intake channels.
Modifying the construction of the piston 2 and one cyilinder crankcase plate 11 concerning intake channels 20 an engine could be constrncted that is lubricated from a carbureted mixture (air, fiiel and oil). Such an engine could widely be applied to machines that require light weight and high revolutions per minute in any work position.
