JPH0526141A - Distributor with integrated ignition coil for internal combustion engine - Google Patents

Abstract

(57) [Summary] [Configuration] An ignition coil for an internal combustion engine, wherein an ignition coil 7 is integrally attached to a housing 2, and a high voltage is applied from the ignition coil 7 to an ignition plug of an angular cylinder of the internal combustion engine by an ignition timing signal. In the electric power distributor, the high voltage tower 8 of the ignition coil 7 is arranged not parallel to the shaft 1 nor to the iron core 11 of the ignition coil 7 at right angles or parallels. According to the present invention, since the high-voltage tower of the ignition coil is not parallel to the shaft of the distributor, the ignition coil can be arranged near the shaft of the distributor, and the high-voltage tower of the ignition coil is a rotating component. Since it does not interfere with, the entire distributor can be downsized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal combustion engine ignition coil integrated type distributor in which an internal combustion engine ignition coil is integrated with a distributor.

[0002]

2. Description of the Related Art A distributor having a structure in which an ignition coil for an internal combustion engine is integrated with a distributor has been proposed in Japanese Patent Publication No. 1-273877.

Among them, the high-voltage tower of the ignition coil is mounted parallel to the shaft. The high-voltage tower is mounted at a right angle on the ignition coil core.

[0004]

[Problems to be Solved by the Invention] Japanese Patent Publication No. 1-273
In the distributor proposed in Japanese Patent No. 877, the distributor projects laterally on the side where the ignition coil is attached, resulting in an increase in the size of the distributor.

Further, since the high-voltage tower is mounted at a right angle to the ignition coil iron core, there is a problem that the ignition coil high-voltage tower and the rotating body interfere when the ignition coil is mounted near the center of the distributor. .

The present invention has been made in consideration of the current situation of the above-described power distributor of the type described above, and an object thereof is to provide an ignition coil integrated power distributor for an internal combustion engine which can be downsized. is there.

[0007]

To achieve the above object, the present invention provides a housing with a shaft that rotates in synchronization with the rotation of an engine, an ignition coil integrally attached to the housing, and an ignition timing signal. In an ignition coil integrated type distributor for an internal combustion engine, wherein a high voltage is applied from the ignition coil to the ignition plug of each cylinder of the engine.
The high-voltage tower of the ignition coil with respect to the shaft,
It is not parallel, and is also arranged at a right angle and not parallel to the ignition coil iron core.

[0008]

According to the present invention, since the high-voltage tower of the ignition coil is not parallel to the shaft of the distributor, the ignition coil can be arranged near the center of the distributor, and the high-voltage tower of the ignition coil is composed of rotating parts. Since it does not interfere with, the entire distributor can be downsized.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view showing an embodiment of the present invention.

As shown in FIG. 1, the housing 2 is provided with a shaft bearing portion 13, and the through hole 1 of the bearing portion 13 is provided.
The shaft 1 is rotatably inserted into the shaft 4. A signal rotor 3 having a slit is attached to the shaft 1 as shown in FIG. 1, and at the end of the shaft 1,
The rotor head 4 is attached.

On the other hand, the housing 2 accommodates the signal detecting device 5 and the ignition coil 7, and covers them.
A cap 6 is fixed to the housing 2. A cap center electrode 9 located at the center of the rotor head 4 and a cap side electrode 10 located laterally of the rotor head 4 are attached to the cap 6.

The above-mentioned ignition coil 7 has a structure in which a winding 12 is wound around a part of an iron core 11 and a high-voltage tower 8 is formed in a protruding manner. As shown in FIG. It is mounted in the recess of the housing 2 near the shaft 1.

Next, the operation of the embodiment having the above-mentioned structure will be described.

The shaft 1 is synchronized with the rotation of an engine (not shown).
The rotation of the signal rotor 3 is detected by the signal detection device 5 as a signal of the crank angle position of the intermittent engine, and the crank angle position signal is input to the control device (not shown). From this controller, an ignition timing signal of the engine is input to the distributor, and a high voltage is induced at the output terminal of the ignition coil 7 by this ignition timing signal.

In this way, the high voltage induced in the ignition coil 7 is supplied from the high voltage tower 8 to the rotor head 4 through the cap center electrode 9 and discharged from the rotor head 4 to the cap side electrode 10. Due to this discharge, a high voltage is applied to the spark plug of each cylinder of the engine (not shown).

According to the embodiment, since the ignition coil 7 is located near the shaft, the entire distributor can be made compact and compact.

[0018]

As described in detail above, according to the present invention, it is possible to provide an ignition coil integrated type distributor for an internal combustion engine, which is miniaturized as a whole.
