PURPOSE:To eliminate high voltage discharge in a distributor by opening and closing the electric contacts of the distributor by rotating magnets. CONSTITUTION:Shafts 10 penetrate through the points of center of gravites of movable magnets 11, 13, one ends of the shafts 10 are fixed to support plates 3 and the movable magnets are capable of being pivoted smoothly about the shafts 10. The contacts 8 for distributing electricity are connected directly to two sets of distributing terminals 2 which are located so as to be capable of being contacted with either one of the movable contacts 9, 12 at a timing when either one of cylinders is distributed with the electricity. According to this method, the high voltage discharge in the distributor may be eliminated.

Description

[Detailed description of the invention] This invention relates to a power distribution device for an internal combustion engine.

For the distribution of high-voltage power for ignition of internal combustion engines that use Karin, a simple method is often used in which a power distribution rotor and a power receiving segment are used to cause high voltage discharge between the two to supply current. This method has drawbacks such as generation of sparks during high-voltage energization, power loss, and generation of high-frequency noise.

Other power distribution methods using advanced technology include one equipped with one set of semiconductor high-voltage generation circuits per cylinder or one set per binary cylinder, and omitting the conventional power distribution device. Problems with complexity and price have prevented it from becoming widespread.

There is also a method in which the ignition timing is detected by a reed switch, a magnetic upper no → no, an optical sensor, etc., and the electromagnetic switch is driven by a semiconductor amplifier. However, although these are contact type, they have not been put into practical use in Japan because of the considerable cost increase and lack of sufficient operational stability.

Is there another method of switching using a large reed switch and a rotor magnet? However, this method is impractical as it has drawbacks in switching speed and durability.

The present invention aims to eliminate loss due to high-pressure discharge and contribute to the output direction of an internal combustion engine by obtaining a power distribution device that is inexpensive and operates stably.

An embodiment of the present invention in the case of a binary cylinder will be described based on the drawings.

Below the two power distribution terminals 2, there are
A power distribution Jη contact 8 is directly connected to the power distribution terminal 2 and is located at a position where it can contact either 9 or the movable contact J slope 9° 12 when power is to be distributed to any cylinder.

N suction and N-N repulsion occur, and the movable pin 1-13 instantly turns 11t upward to the right from the state of -1-0 on the left, releases the movable contacts 7 and 12, and disconnects the power supply from the power distribution terminals 2 and \. Cut off the +- path. Furthermore, when the camshaft continues to rotate and comes to the S pole of the rotor magnet 14 or below the movable macnet 11, each of the magnetos 1 to 1 causes N-8 attraction and S-8 repulsion, and the movable macnet 11 Since it instantly rotates from rising to the left to rising to the right, the movable contacts 5 and 9 are respectively closed and start supplying high voltage power to the power distribution terminal 2 on the right side.

According to the present invention, since both the repulsive and attractive forces of the two poles of the magnet are utilized, it is possible to achieve a much higher speed of switching than with a reed switch.

Sufficiently stable operation is possible even at an engine speed of IO000BPR.1.

Furthermore, since the contacts are completely closed while the spark plug is energized, there is no high-pressure discharge that occurs in conventional power distributors, and various problems can be eliminated.
