Description

 The invention relates to the field of energy and can be used to convert fuel energy into electric current.

 Known energy block converter of fuel energy into electricity, consisting of a straight piston internal combustion engine and an electric current generator consisting of two coils - one inside the other, installed in the crankcase on internal combustion engines [1].

 A disadvantage of the known block is complexity, a large number of parts, low efficiency.

 Also known is an electric alternator combined with an internal combustion engine, a piston - a magnet of which is freely placed in the cylinder with the possibility of reciprocating motion, and shock absorbers are placed in the combustion chambers [2]. He is the closest and adopted as a prototype.

 A disadvantage of the known generator is the mandatory need to manufacture a cylinder from non-magnetic material, a large mass of the piston, the inability to regulate the EMF, low efficiency, low power.

 The objective of the invention is to increase power, efficiency, expanding the scope of the converter.

 The problem is solved in that the fuel-electric converter comprising a stator, an electric winding, a rotor, a cylinder of an internal combustion engine, two pistons, interconnected by mechanical rods and freely placed inside the converter with the formation of combustion chambers, additionally contains a second cylinder mounted opposite to the first, and between they have a stator made of an external, equipped with an excitation winding, and internal parts mounted coaxially, and the electric winding is mounted on a rotor that is installed between the parts of the stator with the possibility of reciprocating motion.

 In this case, the inner part of the stator can be equipped with an excitation winding.

 The proposed Converter has a high efficiency, runs on liquid or gaseous fuel and allows you to receive alternating electric current. High efficiency is achieved due to good filling and ventilation of the cylinders, a high conversion frequency, a small mass of moving parts, small mechanical losses and small losses in the magnetic system. Losses in the stator magnetic system are small due to the coaxial arrangement of the stator parts, which provides low resistance to magnetic flux and perpendicularity of the magnetic flux lines to the direction of motion of the rotor. In addition, due to the use of the field winding, it is possible to regulate the resulting emf by changing the excitation current.

 In addition, the proposed device will allow for the installation of two converters in one block sequentially one after the other when the rotors (or stators) are turned on in phase to provide vibration compensation, since the movement of the moving parts will be synchronous and antiphase. The proposed converter is characterized by durability, since it has few friction and heavily loaded parts.

 In FIG. 1 schematically shows a vertical section, in FIG. 2 is a horizontal section through a fuel-electric converter.

 The converter contains two opposed cylinders 1, 2 with pistons 3, 4 connected to rods 4, 5, 6, 7, on which the rotor 8 is fixed, with a working winding 9, which moves inside the stator magnetic system, consisting of the outer 10, with a winding excitation 11, and the inner 12 parts located coaxially. The cylinders have inlets 13 for supplying a combustible mixture, exhaust ports 14 for exhaust gases, bypass channels 15, 16 and spark plugs 17, 18. The sliding contacts of the rotor 19, 20, the fixed contacts of the stator 21, 22 and the power leads 23, 24 form rotor chain. Intermediate bearings 25, 26 are used to secure the cylinders and the stator. The ignition timing sensor and start switch are not shown.

 The device operates as follows.

 When starting, the stator winding 11 and the rotor winding 9 are supplied with electric current, for example, from a battery. The current of the stator winding 11 generates a magnetic flux whose lines are perpendicular to the direction of the line of motion of the rotor 8. The current flowing along the winding of the rotor 9 creates a force whose direction depends on the polarity of the rotor. When moving the pistons 3, 4 in one of the cylinders 1, 2 will be suction, and in the other compression of the working mixture. At the moment determined by the sensors of the ignition moment, the mixture is ignited by one of the spark plugs 17, 18, the pistons 3, 4 and the rotor 8 flash and move in the opposite direction under the influence of gas pressure. At this moment, the start switch changes the polarity of the current of the rotor 8, which increases the speed of the pistons 3, 4 and rotor 8, and compression, flash, and stroke occur in another cylinder. The starting current from the rotor is disconnected, the converter starts. In the process, in the cylinders 1, 2, compression, flash, and stroke occur in turn. The rotor 8 moves back and forth and crosses the magnetic flux lines of the stator 10, 12, an alternating electric current is generated in the winding of the rotor 9, which is removed from the sliding contacts of the rotor 19, 20 to the stationary contacts of the stator 21, 22 and is output by the power terminals 22, 23 to the load terminals . The converter EMF depends on both the conversion frequency and the stator current. With an increase in the frequency or current of the stator, ceteris paribus, the EMF will increase.

 Thus, in comparison with the prototype, the proposed design allows you to create light, powerful, economical and durable converters of fuel energy into electric current.
