Differences between pointless electronic ignition and capacitor discharge ignition

[bertos]

How differences between pointless electronic ignition and capacitor discharge ignition?

Is there any differences?

Not sure what your application is, but you are talking about two different animals. Apples and oranges. A capacitive discharge ignition can work on ignitions with points or with pointless ignitions. One has nothing to do with the other. Some pointless ignitons are capacitive discharge by design, some are not.

The main idea behind CD ignitions is to store much higher than the 12 volts that fire the ignition coil in a standard system. They instead will rapidly built to 400 volts DC for example and hit the ignition coil with that voltage instead of 12 VDC resulting in a hotter spark being generated by the ignition coil. Whether this firing is done by Hall-effect pointless ignitions or by mechanical points is immaterial to the working of the CD electonics.

And it's all fairly outdated now with coil-on-plug and computer timed and operated igintions replacing the distributors.

Dear Mike

I have seen in the specification of Yamaha outboard that the Ignition system is
CDI. That why I'm wondering how differences compared with pointless electronic ignition by Suzuki

Best regards

As far as I know, all the modern day outboards are going to have pointless ignition, regardless of brand. And to meet emissions standards, they are also all electronically controlled. I personally would not choose a motor based on whether it's ignition system is listed as "CDI". Because virtually all of them are going to have systems that incorporate capacitors as well as inductive coils to provide the fire. As far as I'm concerned, any such "CDI" listing is a marketing tool now.

Both Yamaha and Suzuki make good outboards. Your local dealer network availability and dealer reputation would be a better criterion on which to base your choice, in my opinion.
