EP0093822A1 - Continuous combustion rotating piston engine - Google Patents

Abstract

The continuous combustion piston engine has a number of cylinders arranged around a central drive shaft (1), with the cylinder axes inclinable to the shaft axis. Each cylinder has a piston which drives a separate crankshaft (10). Each crankshaft has a bevel pinion (8) which engages a bevel wheel (7) rigidly connected to a stationary housing (5). The cylinder and piston assembly rotates with the drive shaft at half the speed of the separate crankshafts. Cylinder ports (15) are aligned alternately with inlet (3) and exhaust ducts (16). The inlet duct communicates with the continuously operating combustion chamber.

Description

The engine according to the invention is a new development. The following description relates to the functional principle and the elements contributing to the movement with the aim of explaining them in the present patent application without going into certain details relating to construction. The engine consists of a cylinder block rotating around the drive shaft, together with the variable-volume chambers formed by the general means (piston, connecting rod - crankshaft), the whole of which is enclosed in an appropriately sized housing and the cylinder head.

In Figure 1, the cylinder head (17) is shown, in which two openings, one to the outlet (2o) and the other to the inlet (21) are provided, which are connected to the respective lines (16) and (3); there is also the holder for the spark plug or the on Spray valve (18) which is in communication with the combustion chamber (19).

Figure 2 shows the rotating structure, which consists of the following main parts for functional purposes: the drive shaft (1) which is fixedly connected to the rotatable cylinder block (4), in which a certain number of cylinders is provided, in the embodiment six cylinders The chambers of variable volume (14) for the rotary movement are formed within these cylinders and are transferred to the pistons via the bevel gear transmission by means of the connecting rod crankshaft power transmission system.

A movable connection is created between the rotatable cylinder block (4) and the cylinder head (17), which ensures the perfect sealing of the gases contained in the cylinders during their work cycle movement (with suitable lubrication).

The bevel gears designed for a reduction ratio of 2: 1 consist of a ring gear (7) attached to the housing and freely rotating on the drive shaft, on which six pinions (8) roll and thus rotate around the drive shaft, by generating the alternating movement of the pistons (12) by rotating their own axis by means of connecting rods and crankshafts (10-11).

function

A feature of this engine is that it performs continuous combustion in a single combustion chamber, which is clocked in conjunction with the Is brought chambers of variable volume, which are determined by the rotational movement of the cylinder block (4).

The engine according to the invention has the characteristic function of the four-stroke internal combustion engines, which carry out the heat stroke in the four characteristic phases of intake - compression - combustion or explode and work - discharge at two revolutions of the crankshaft; whereas in normal engines these phases take place cyclically in the same cylinder and independently of each other through the system of intake or injection for each cylinder, in our case the heat cycle takes place through one revolution of the drive shaft and the different chambers of the rotatable cylinder block become consecutive and cyclical in accordance brought with the single combustion chamber of the cylinder head (19).

If in particular any one of the cylinders contained in the rotatable cylinder block (4) is taken into account, the position of the piston in the top dead center position being assumed, the line (15) gradually comes into connection with the intake opening in the position of the intake start (21) and thereby causes the cylinder to be filled after a quarter turn of the drive shaft (1) and the movement of the piston from the TDC position to the bottom dead center position (TDC position), which is caused by the rotation by 180 ° (half a turn ) the crankshaft (10) takes place, which forms a unit with the pinion (8), which is connected to the fixed ring gear (7) in a ratio of 2: 1, which is necessary and essential to ensure an accurate distribution of the four phases achieve. With a further rotation of this cylinder by a quarter turn, the compression phase takes place between the cylinder and the lower wall of the cylinder head, on which the rotatable cylinder block slides; the piston moves from the bottom position to the top position and then comes the Line (15) in connection with the chamber (19), which is appropriately dimensioned to achieve continuous combustion, that is, while in the cylinder concerned the work phase begins and the combustion ends, the combustion then begins. This combustion can be triggered according to the cycle carried out by igniting the candle in the explosion engine, and once it has started, it operates for the cyclical supply of the cylinders which are passed one after the other.

During compression operation, the combustion is triggered and maintained by the injection valve arranged in the combustion chamber (19).

In the further course of the rotary movement of the cylinder mentioned, after a quarter turn it has completed the active working phase and the piston moves from TDC to LDC; in this position the ejection phase begins and the line (15) gradually comes into connection with the outlet opening (20); this output is stopped in the last quarter turn of the rotatable cylinder block and thus the drive shaft, it being evident that the different phases of the cycle take place during one revolution of the drive shaft (1).

It can be said briefly that the rotation of the cylinders serves to suck in the mixture or the fuel with which they subsequently expediently supply the combustion in continuous operation from the same opening.

In both types, the engine can be designed in a conventional manner as an explosion engine or as an internal combustion engine with compression, in that the space (19) is designed accordingly, and in the first case the candle required for igniting the combustion and in the second case the complicated injection structure for the fuel has to be inserted.

As can be seen, the engine can operate with continuous combustion as described above, but also according to conventional systems with single explosion or injection into each individual cylinder.
