Winterburn Ignition System
Permalink  
 


Folks,

     My late father F.L. Winterburn invented the first viable, commercially successful CD ignition in 1962. It was being manufactured by Hyland Electronics in Ottawa Ontario within a year and the design spread rapidly throughout North America within another two years. And no, my father did not get rich although a few lawyers made money fighting court battles for him.

     I have recently started to manufacture a modern variant that uses the old dependable design except that it will also work on positive or negative ground cars without any wiring changes. As far as CD ignitions go, this one gives a long duration spark and uses very little energy. 12V models use less than 3 amps and 6V models less than 3.5 amps at full rpm which is limited to 8000rpm on an 8 cylinder or 16000 on a 4 banger. It is triggered by points only, but that gives it the advantage of having a switch to go back to 'Kettering' if need be. The switch also has a centre 'off' position. The case is cast aluminum and the switch is O-ring sealed. The unit is splash proof but not potted so that it can be repaired if need be. The internal components are all highly over-rated. I've made the units with TO3 style transistors for the power supply and attempted to keep the 1960s style look to the unit.

This unit is specifically made for vintage cars and is voltage controlled to prevent damage to vintage stock ignition components. It will start a car as low as 3.7 volts battery input, and will tolerate high charging system voltages without damage. These units are all hand built by me.

If you would like more information email me at winterburnignition@gmail.com . I check that email at least once a day.

so what this invention does is make the points simply a momentary contact that tells this unit to make spark.  so no burned out points but wont work with a magnetic trigger?  so it allows full voltage spark?  sounds neat

why wont this work with a magnetic trigger?

 Fatstax, there is no magnetic trigger for a few reasons. First of all, points in this application aren't voltage sensitive and will provide a reliable trigger down to as low as the sensing voltage of this CD unit which is at least as low as 3.7V.  Secondly, points in this application are very reliable with only a couple of failure modes(broken spring, open circuit due to broken wire) which almost never happen. Retaining the points makes troubleshooting ignition problems dead easy and the ability to switch from one kind of ignition to another gives redundancy and reliability that no magnetic trigger could possibly give. A magnetic trigger of whatever variety requires more complex electronics and the possibility of failure increases in proportion to the increased complexity. The trigger circuit in this CDI doesn't get much simpler. The basics are a capacitor (to trigger the SCR gate), a diode to feed the trigger capacitor and block the discharging of the capacitor when the points re-close, and a resistor to bleed off the trigger capacitor slowly between each firing to make it immune to points bounce. It will reliably trigger the SCR down to minus 50C and up to 125C. And since the trigger is being controlled by a mechanical switch that is not temperature or voltage sensitive, you have a solid foundation for reliable triggering.

 For example, some years ago I converted a car that had a Hall effect magnetic pickup in the distributor that triggered a 'transistor switch' type of inductive electronic ignition to trigger a Accel 300+ CDI instead. I had to do a conversion to get the Accel unit to recognize the Hall effect signal but that wasn't the problem. That powerful, multispark CDI did start the car better, but on some very cold mornings it would not start until the starter motor was suddenly disengaged as the battery voltage rose. I reasoned that on those cold mornings the battery voltage was dropping below what the Accel CDI could run at, so I installed a motorcycle battery just to run the CDI. It made no difference. Turns out the Hall effect trigger would not operate well below 10V. Also, the electronics in that CDI seemed to be more temperature sensitive than they should have been. Points aren't like that, and well chosen components in the simple CDI points trigger aren't either. Also, the ability of points to perform their function well is consistent across the range of car makes and years since all they are is a mechanical switch. Fred

Fred just wondering if you have contacted any of the local rod shops like Horton's or Candy's. Bubbas comes to mind on the U S side Seems to be the go to guy for anything to do with distributor's on most of the old car boards. I got to do a swap with the 235 this winter I do have a converted HEI but was thinking about leaving the stock distributer  in this one so what i need to Know is how much for the 12 V unit and what wires you would recommend. thanks Dorian

New website for this ignition system.  Will possibly expand it in the future.  capacitordischargeignition.com
