RU57834U1 - FASTENKO ROTARY ENGINE - Google Patents

Abstract

The Fastenko rotary engine refers to engine building and can be used as an internal combustion engine of vehicles.

The engine consists of a cylindrical housing with two rotors installed in it enclosed in each other.

The rotors alternately rotating in the engine block simultaneously create four cameras:

I combustion chamber

II exhaust chamber

III suction chamber

IV compression chamber.

To control the rotors, two rotating clamps and a differential are used, which translates the intermittent movements of the rotors into continuous motion of the working shaft of the engine.

Description

A rotary engine relates to engine building and can be used as an internal combustion engine of vehicles.

There is a rotary engine made according to the scheme of F. Wankel. Known for the rotary engine of Troyan RU 2131983 since 1 2000. Rotary engines having a cylindrical body with two rotors installed in it and embedded in each other are patented. RU 2151893 from 1 2000; RU 2193094 since 1 2001; RU 2076934 since 1 1997; RU 2043521 from 1 1995;

Taken as an analogue rotary engine RU 2014479 since 1 1994. It has a mechanism that synchronizes the movement of rotors, kinematically connected by means of eccentrics and connecting rods to the motor shaft.

In contrast to the analogue, the proposed design of the rotary engine has a rotor movement control mechanism, which is located outside the engine casing and consists of gears 5 and 6 (Fig. 3) connected to rotor 2 and gears 7 and 8 connected to rotor 3. The gears alternately transmit the force on the differential 11, which is connected with the working shaft of the engine. For one revolution of the engine there are two working moves.

The engine duty cycle is as follows:

In the cylindrical casing of engine 1 (Fig. 1), two rotors 2 and 3 rotate alternately, creating four chambers simultaneously.

I combustion chamber;

II exhaust chamber;

III suction chamber;

IV compression chamber;

After the ignition of the working mixture in the chamber 1 (Fig. 2), the rotor 2 is held by the rotating lock 10 in a stationary state, and the rotor 3 undergoes a working stroke under gas pressure. A rotating lock holds the rotor 2 until the compression of the working mixture in chamber IV is completed, after which the lock releases the rotor 2 and both rotors 2 and 3 rotate together bringing the compressed working mixture under the spark plug 5. The working mixture ignites. Further, the gas pressure stops the rotation of the rotor 3, and the latch 9 (Fig. 3) keeps it stationary, and the rotor 2 makes a working stroke, transmitting force through gears to the differential, which in turn rotates the working shaft of the engine. Next, the cycle repeats.

This embodiment of the engine creates not only its compactness due to the small number of moving parts, but significantly simplifies the engine increasing its reliability.

Figure 3 shows the stops for the clamps 12, which can be performed using rolling bearings.

Fig. 1 shows a fixed axis 4 through which oil can be pumped to cool and lubricate the engine bearings.

Claims (1)

A four-stroke rotary engine, comprising a cylindrical housing with two rotors installed in it, rotationally secured retainers holding the rotors, and a differential that converts the intermittent motion of the rotors into continuous movement of the working shaft, characterized in that the engine is equipped with gears located outside the housing and associated with rotors for alternating transmission of force to the differential.
