Abstract

The solution is a piston rotary internal combustion engine, the crank shaft (2) being anchored to the engine frame (18) and not rotating. The cylinder block (1) rotates around the main crankshaft bearings (3) of the crankshaft (2) and carries with it a connecting rod, piston, piston pin and piston ring assembly (4) rotating about the crankshaft connecting rod pin (5). The combination of these two rotational movements results in a suction and compression stroke. The fuel mixture is fed into the cylinder (1) through the opening (7) in the crankshaft (2) through the collector (8) and the pipe (6). The collector (8) and the pipe (6) are fixedly connected to the block and the cylinder (1). Exhaust gases are discharged through cylinders (1) via line (9) through collector (12) and hole (10) in crankshaft (2). The collector (12) and the pipe (9) are fixedly connected to the block and the cylinder (1). Ignition of the mixture is a high voltage (17) through the pre-spark plug (16) in the cylinder head. The counterweight (14) balances the cylinder block (1) and the piston, piston pin, piston ring and connecting rod assembly (4). The crankshaft is sealed against the rotating collectors (6) and (12) by the sealing rings (11) and (15).

Description

Reciprocating internal combustion engine.

Technical field:

The present invention relates to a wide field of technology using internal combustion engines to power machines, vehicles and aircraft.

BACKGROUND OF THE INVENTION:

Known reciprocating internal combustion engines are conventional two- or four-stroke, gasoline, diesel or gas piston engines, a Wankel rotary-piston engine and other rotary engines characterized by a variety of piston, cylinder, valve, slide, pulley, cam, cam track and lever assemblies.

SUMMARY OF THE INVENTION:

The present invention is developed as an alternative to conventional two-stroke, four-stroke, gasoline, diesel or gas piston engines.

The present invention eliminates repetitive reciprocating movements of the piston, piston pin, piston rings and connecting rod masses of a conventional piston engine in which mechanical work is lost and thus the engine's considerably low efficiency and replaces these movements with a rotary motion wherein the cylinder and piston rotate around a non-rotating crankshaft. fixed to the frame.

It also eliminates the drawbacks of the Wankel rotary engine with the combustion chamber sealing and the durability of the sealing parts.

The present invention, by its simplicity and the familiar composition of the individual components, removes the complex composition of pistons, cylinders, valves, sliders, pulleys, cams, cam tracks and levers of other rotary engines. The present invention has minimal mechanical energy losses and thus substantially higher liter power, resulting in less engine content, reduced weight, and fewer emissions of the equivalent engine.

The present invention is constantly cooled with air by its rotary motion, thereby eliminating the water pump, water cooler, piping system, thermostat, fan, and drive belt with pulleys to drive the fan, resulting in a further reduction in engine weight.

The same applies to air-cooled engines in proportional form. The present invention achieves significantly higher engine speeds compared to conventional piston engines, particularly when using turbochargers, fuel injection and desmodromic manifolds.

Description of exemplary embodiments.

The simplest embodiment of the present invention in the attached sketch shows the characteristic arrangement of the engine and distinguishes it from a conventional piston engine by moving the engine parts so that the engine crankshaft 2 is non-rotatable and attached to the engine frame 18 and the cylinder block 1 rotates The piston, piston rings, piston pin and connecting rod assembly 4 also rotate around the crankshaft 2 and its connecting rod pin 5. The engine operates in this two-stroke design so that the fuel mixture enters the engine through the bore 7 in the crankshaft via the collector 8 and the pipe 6.

The flue gases leave the engine via line 9 through the collector 12 and the crankshaft bore 10. The collectors 8 and 12 are connected to the block and cylinder and are sealed against the standing crankshaft by gaskets 11 and 15.

The mixture is ignited by the spark plug 16 and the high voltage 17 through the spark gap.

The balance of the engine mass is a counterweight 14. The gear 19 serves to transfer the driving force to the clutch and the transmission.

In another two-stroke embodiment, the counterweight 14 is replaced by a counter-piston with a piston in the same axis wherein the intake, compression, explosion, and exhaust take place simultaneously in both cylinders, the connecting rods of the individual cylinders being attached to the crankshaft journals rotated by 180.

In the four-stroke engine version, due to the rotation of the cylinder / piston block, the lubricating oil is sucked out and returned to the lubrication cycle due to centrifugal forces from the peripheral parts.

In another four-stroke version of highly stressed engines, where the engine cooling by its rotation is insufficient, collectors are used for the supply and exhaust of the coolant.

Industrial Applicability:

The present invention is particularly applicable to racing motorcycles and cars with regard to the possibility of achieving high speeds. When using the engine commercially, safety must be ensured with respect to the rotating cylinder block.
