Abstract

PURPOSE:To make a simultaneous ignition system practicable with a simple structure as well as to secure favorable ignitability, by installing a current sensor in a high tension cord to be connected to a cylinder, while setting an output signal out of the current censor down to a cylinder discrimination signal. CONSTITUTION:The high voltage generated in an ignition coil 1 is distributed with a distributor 2 and fed to a spark plug in a cylinder via a high-tension cord 3. In this case, a current sensor 4 is installed in this cord 3, detecting an electric current flowing in time of discharging. And, an electric signal to be outputted out of the current sensor 4 is processed at a signal processing part 5, setting it down to a cylinder discrimination signal which is inputted into a simultaneous ignition system circuit. With this constitution, even in case of cars other then those being computerized and capable of outputting this cylinder discrimination signal are able to adopt this simultaneous ignition system. Thus, favorable ignitability is securable with a simple structure.

Description

【発明の詳細な説明】 ［産業上の利用分野］ 本発明は自動車エンジン等の同時点火方式における気筒
判別方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cylinder discrimination method in a simultaneous ignition system of an automobile engine or the like.

市販されている。[Prior Art] Conventionally, as a method for igniting fuel in automobile engines, etc.,
As shown in Figure 4, the ignition coil generates high voltage and a distributor distributes it to the spark plugs of each cylinder. The disadvantage is that loss occurs and the spark becomes weaker. Therefore, in order to strengthen the spark, ignition devices such as CD'I are commercially available.

This is called the simultaneous ignition method, and because it does not use a distributor, (1) spark discharge from the tip of the rotor inside the distributor becomes stronger, reducing radio interference (2) higher secondary voltage. Even if this occurs, there is no need to consider the dielectric breakdown resistance of the rotor or cap (3) maintenance for ignition timing adjustment and mechanical wear can be reduced.

しなければならないという問題点がある。[Problems to be solved by the invention] Although the conventional simultaneous ignition system has the above advantages,
Since a cylinder discrimination signal is required, this can only be installed on some car models such as ECC5 and TCC5 that are computer-controlled and can output a cylinder discrimination signal. However, there is a problem in that the inside of the distributor must be newly modified to make it possible to obtain a cylinder discrimination signal.

This system was developed with the aim of providing a method for easily obtaining a cylinder discrimination signal, and its configuration is such that a current sensor is installed in the high tension cord connected to the cylinder, and the output of the current sensor is This is characterized in that the signal is a cylinder discrimination signal.

It consists of a coil and is used to detect the current flowing during discharge. Reference numeral 5 denotes a signal processing unit that processes the electrical signal output from the current sensor 4 and generates a cylinder discrimination signal.
