    • PURPOSE:To reduce power-loss to prevent radio wave noise, by providing a pair of secondary windings on the secondary side of an ignition coil, by connecting a pair of semiconductor rectifying means to the terminals of the windings, and by connecting spark plugs to the means. CONSTITUTION:An ignition control circuit 20 is connected to the primary side of an ignition coil 2 through power transistors 27A, 27B. A pair of secondary windings 4A, 4B are provided on the secondary side of the ignition coil 2, and a D.C. high voltage source 30 is connected to a common terminal 54. A pair of diodes 50a through 50d as semiconductor rectifying means are connected in parallel to the other terminals 55, 56, and spark plugs 6a through 6d are connected in series to the diodes 50a, 50b. With this arrangement power-loss may be remarkably reduced, and simultaneously, radio wave noise may be greatly prevented.

    • 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.
    • 目的:使用简单的结构实现同时点火系统,并确保良好的点火性能,通过将电流传感器安装在连接到气缸的高压电缆中,同时将输出信号从当前检查器设置到 气缸鉴别信号。 构成:点火线圈1中产生的高电压通过分配器2分配,经由高压线3送入气缸中的火花塞。在这种情况下,电流传感器4安装在该线3中,检测 在放电时流过的电流。 并且,在信号处理部5处理从电流传感器4输出的电信号,将其设定为输入同时点火系统电路的气缸判别信号。 利用这种结构,即使在其他的情况下,那些被计算机化并且能够输出该气缸鉴别信号的汽车也能够采用该同时点火系统。 因此,具有简单结构的良好的可燃性是可靠的。
