The invention relates to sources of electricity that are installed on the internal combustion engines of vehicles, in particular motorcycles, to power the ignition systems of these engines and on-Board network of the motor vehicles (lights, lights, lighting devices).

Known generator for the ignition system and the development of additional energy (see U.S. patent 4418677, CL F 02 P 1/02, 5/04, 3/06, publ. 6.12.83 year ). The generator includes a flywheel, a few magnets and the stator. On the inner surface of the flywheel from rotating internal combustion engine, in a common plane with several magnets equally spaced around the circumference. The engine inside of the flywheel and concentric with the flywheel installed the stator, which consists of an annular core of magnetic material and has a number of equally spaced poles for power users current and at least two poles of the ignition system. The first pole is located in the plane of the magnets. Pole ignition system shifted relative to this plane. At the poles, designed for power users that is Otok for low and high speed.

The described device has the following disadvantages.

The design of the generator is complicated due to the use of separate magnets on the rotor and placement of stator poles in different planes for power windings and the windings of the ignition. The use of separate magnets on the rotor due to the difficulty of attaching them. Placement of stator poles in equal planes increases the axial dimension of the generator, which for most internal combustion engines is very limited. The use of different windings of the ignition for low and high speed is obsolete and has been seen in low-energy magnetic systems. The specific (per unit volume), the power of the generator is small and the power of consumers is limited.

Known noncontact maggino (see ed. mon. The USSR 569742, CL F 02 R. 1/02) containing a flywheel with magnets, pole pieces, the base with charging, lighting and control windings placed on the core. At least two pole tip adjacent to one of the magnets with beaks that are offset one relative to another, together with the cores of governors of the windings in the axial direction. The flywheel rotor and housing cone made of different parts.

Known generator flywheel AC for the vehicle (see U.S. patent 5072714, CL F 02 P 1/02, 3/06, H 02 To 7/02, publ. 17.12.91 g) adopted for the prototype. The generator includes a rotor made in the form of a flywheel with a landing cone and permanent magnets and pole pieces, placed on the inner surface of the flywheel, forming an asymmetric magnetic field, and a stator in the form of sprockets with different numbers of poles placed on them by the windings of the control and ignition, while the control winding connected in opposite. The power winding is missing.

The disadvantages of the prototype are low energy magnetic system generator providing only the ignition, and the high complexity of the mounting of the individual magnets and pole pieces.

Object of the present invention is to provide a range of compact uniform generators flywheel AC for vehicles, in particular motor the tion, is to provide greater power generator in small dimensions, increase the service life and operational reliability of the generator, providing the possibility of applying the most modern electronic ignition and stabilization of the on-Board voltage vehicles, ensuring minimal complexity of manufacturing generators.

This technical result is achieved by the fact that the flywheel generator AC for vehicles containing the rotor, made in the form of a flywheel with a landing cone and a permanent magnet placed on the inner surface of the flywheel and magnetized asymmetric magnetic field, and a stator in the form of sprockets with different numbers of poles and placed them wound management and ignition, while the control winding connected in opposite, the flywheel rotor and housing cone is made of a single piece of magnetic material, a permanent magnet rotor is made from the annular magnetoplasma based on neodymium, iron, boron and a polymeric binder with rubber and has energy NSWG>170 Tlcom-1between the bottom of the flywheel and magnet set ring solid is Gnesinyh consistently N and S, (2P-3) pole sector area have a width ofand one -3obeying equation (2P-3)+3= 360and the normal component of magnetic induction in the conditions of open magnetic flux in the middle of the pie sections of a width ofand at a distance from the edges of the pie plot width of 3above normal component of the magnetic induction in the middle of the pie plot width of 3on the stator additionally made winding power the on-Board network of the vehicle, the number of control windings of the multiple of two and the total number of windings of the ignition and power on-Board network 6, remaining even number.

The new version of the rotor and stator, the use of new materials, the introduction of additional windings allows you to get a generator of high power with small size and high service life and operational reliability. At the same time ensures a minimum complexity of manufacturing of the generator.

Based on the above we can conclude that the proposed technical solution has novelty and inventive steps.

The two adjacent stator poles are occupied by the windings of the control, and (2P-2) pole - windings of the ignition and power on-Board network.

The generator works as follows.

During the rotation of the generator rotor relative to the stator pole pie plots magnet 3 generates electric current in the windings 6 of the stator. The sector width of 3passing two adjacent poles of the stator, on which is placed a winding control system C is that the ignition system provides for igniting the engine spark one spark per revolution of the crankshaft, what you need to work single-cylinder two-stroke engine. All sector areas of a width ofpassing two adjacent poles of the stator, which are the control winding of the ignition, do not generate electric current in them, because the windings connected in opposite.

FIELD: engines and pumps.

SUBSTANCE: invention concerns ignition systems of internal combustion engines with inductive and capacitive energy storage and can be used in ignition systems of internal combustion engines. Method of discharge voltage reduction in ignition systems of internal combustion engines with inductive and capacitive energy storage consists that spark discharge series is enabled before ignition point when the cylinder pressure is lower than it is at the ignition point, and discharge voltage is lower up to the values 8-10 times less during inlet stroke if the cylinder pressure does not exceed the atmospheric pressure. Spark discharge energy is sufficient for discharge gap breakdown. Due to residual ionisation, spark discharge repetition frequency supports the discharge gap breakdown. Breakdown voltage of the next discharge remains lower than maximum permissible for the used ignition system regardless of pressure increase. Spark discharge duration and energy are insufficient for blended fuel ignition. At the ignition point, spark discharge or discharges energy increases to the value sufficient for blended fuel ignition.

EFFECT: electric loss enhancement in ignition system, more reliable performance, improved engine efficiency and capacity.
