Abstract

Subject of the invention is a rotating internal combustion engine where the compression is generated separately by way of compressor. The technical problem solved by this invention is how such an engine construction would allow a higher energy efficiency rate compared to existing readily available internal combustion engines. The technical problem is solved according to the invention by separating a suction and compression stroke from the combustion chamber by way of separate compressor and the shape of the piston within the cylinder where the combustion chamber is separated by a moving barrier whose shifting is provided by the shape of the piston itself. Compressed air from the chamber with permanent operating pressure is supplied to the cylinder.

Description

ROTATION ENGINE WITH INTERNAL COMBUSTION AND EXTERNAL

COMPRESSOR

The subject of the invention is a rotary internal combustion engine in which compression is created separately with an external compressor.

A technical problem solved by the invention is such an engine construction that will allow for greater energy utilization in comparison with the known internal combustion engines.

There are many known solutions, the most famous being the Quaziturbine and the Wankl engine. The disadvantages of these engines are mainly the sealing and the small force on the axis of rotation. In fact, a large part of the force even acts against the direction of rotation and thus inhibits it, thereby losing a lot of energy.

The technical problem according to the invention is solved by separating the suction and compression stroke from the combustion chamber by means of a separate compressor and the piston shape in the cylinder, where the combustion chamber is separated by a movable barrier, the displacement of which is facilitated by the piston shape itself. The compressed air is already entering the cylinder.

The features of the invention are explained in more detail below by means of figures showing:

Description of compressor operation (Figure 1):

The piston captures a large amount of air and expels almost everything from the cylinder. Due to the shape of the piston (4), pressures are created slowly and not at the end, and the air displacement due to the shape of the piston also provides exceptional compression properties. The volume does not shrink in proportion but slower towards the end, and such a large force on a small volume allows great pressures. The pressure of the movable bar (3) is applied to the piston walls (4) by a spring (2).

A large amount of air is stored in the pressure vessel (1), which is filled with a compressor or several compressors, which in addition to filling the pressure vessel (1) also have the function of energy utilization when braking the vehicle. This is achieved by placing three compressors of different capacity on the drive axle or axles. The compressors are of different capacities depending on the pressure we want to create or the amount of air required, as well as the braking force. This creates several levels of compression-resistance. Releasing the accelerator pedal to a greater degree means braking control. This would put 7 brake levels on the pedal, which comes with three compressors. 1st stage-1st compressor, 2nd stage2. compressor ... 4th level l.in 2nd compressor ... 7th level l., 2. and 3. compressor. The driver thus regulates the braking power, which enables the compressor to brake compressor, and the required air is stored in the pressure vessel (1). This way, we save energy with minimal losses, as the pressure in the tank does not decrease with time. This air is then used in the engine in compression stroke.

The compressors must be connected to the drive axle or axles, if necessary, in case of pressure drop in the pressure vessel (1) and when braking. This utilizes the energy in braking that has been lost so far.

Compressors are also activated when pressure drops in the pressure vessel, namely:

1) the pressure in the tank drops below the minimum limit => switch on

1.compressor for lower pressures and higher air flow

2) the pressure is still dropping => the 2nd or even 3rd compressor starts.

Engine operation (Figure 2):

From the pressure vessel (1), the air is drawn through a pressure reducing valve (8) into the chamber next to the cylinder of the engine (7), which allows us constant operating pressure. From this chamber, the desired amount of air is discharged into the engine cylinder by means of a computer-controlled valve (6). The fuel is added according to already known injection principles and the expansion of the rotated piston (4). With a gasoline engine, we need, as is known, a spark plug for the required spark. The moment of ignition must not be before the movable barrier (3) reaches the lowest point, as a large pressure on the wall of the movable barrier would prevent the movable barrier from moving downwards, thus creating a "hole" or "hole". loss of compression. However, ignition can be delayed at any time, which allows us to increase the working capacity (computer controlled) and thus the flexibility of the engine according to needs. Given that the volume of the cylinder is relatively large, compression can be fully utilized throughout the cylinder. The pressure of the movable lock (3) on the walls of the piston (4) is made by a spring (2) or otherwise.
