Water Sparkplug Practical Application

[Redmeanie]

Perfect!

Jetijs,

Two Questions:
1- Would the relays be fast enough for engine operation?
2- Would it be possible to use something else instead of a UPS?

These are the things that is better to be brought into consideration.

Elias,
Red already answered the question about relay switching.
As for the UPS, you can also use a separate battery and an inverter. It is not important how you get your 100-200v for the LV side

[Jetijs]

I got my relays, capacitors and a whole bunch of diodes today. The relay is operated by 12v and is intended to switch up to 8A at 250V. They are two pole relays so I can use them to compleatly decouple the cap from the charging side on both - positive and negative wire. I don't know if this is necessary, because it still works if just one wire (positive) is used for switching. The caps are 400v 100uF electrolytic. Diodes are 1n5408. I still need to get the ignition coils. I have a car jung yard near my work, but they wont have four identical ignition coils, so I will need to use different ones. Do you think that this will be a problem?




Also, Red, I checked if the distributor of my car could work as a 12v switch, well, it does not work that way. There is a gap between contacts so that only high voltage can jump across. What can we do about that?

[Redmeanie]

Jet,
Can you bend the contact up on the rotor? Just to narrow the Gap until it is as close as we can get it without touching? Then put something like a bulb or similar to pull more of a load on the relay coil ground side.

I was thinking back through some of meyers Patents last night and remembered that he had actually developed a distributer cap device to trigger his injector setup.

So I started to think, if we need to, to put a Magnet in the rotor, and modify the cap to hold "Hall Effect" Switches or similar in the spots where the plug wires would normally connect.

What do you think?

[Jetijs]

Yes, Red,
I will probably have to make the distributor mod. Will post the cap and rotor pictures tomorrow. I think that I will be able to attach a magnet on the rotor. But what about pulse width? I have never worked with hall switches, but I suppose they work something like the reedswitch except that reedswithces do not require a power source. If that is so, then I will get a longer ON time when the switch is closer to the magnet and shorter ON time when the magnet is further away. We need to take into account that at more motor RPM's, the pulse ON time might be too short fo the relay to switch properly.

Yes your right, Im thinking of pulling some cam and crank sensors at the Junk Yard and trying that route. They are more like Heavy Duty REED Switches. The Hall Effect Might Not Work. But these types definetly will.

[Redmeanie]

Jet,
Just figured a way to duplicate Meyers Design. Without a Bunch of led's.

Use Slotted Opto Sensors like this: SLOTTED OPTO SENSOR | AllElectronics.com

Mount a thin plastic or metal piece vertically on the Rotor to break the Beam.

This is exactly what Meyers was doing. But his had a cylinder that spun on the rotor, that was solid with one slit in it, effectively making a normally open circuit that closed when the slot went by.

This is another option that would surely give an instant trigger.

Yeah look this... ICE on idle 800 RPM = 13.33 Rev per second on 4 cyl engine = 3.33 Hertz. Only for run motor on Idle, some engines idle is low or high.

[Jetijs]

Reed switches can work even at 100Hz, relays maybe about 10Hz, still, it would be about 2400 RPM.

[Jetijs]

Red, the optotriggers would work great, but that requires serious changes in the ignition system and lot of work. That's why I will probably at first try just piggybacking the HV impulses of the stock ignition system with LV boost. Will see what that does

[Redmeanie]

Reed switches can work even at 100Hz, relays maybe about 10Hz, still, it would be about 2400 RPM.

There are Thousands of High Frequency Relays available, I think this might be something to look into. I just Googled it and almost every major manufacturer makes them.

Uff, I don't known that, about Reed Switches max freq on reed switches, but, I have seen all your work in the forum, about Electrical Motor Secrets and others, and your works alwasys is great.... If ICE 4 cyl run with only on idle, your work is very important above all and would be a great advance.

Don't stop, for my comments, my comments were only for info way...

@Jetijs

No, you don't need any slotted optical interrupters. It can be done more elegantly with reflective optical sensors. Also, I doubt it will be so complicated making semiconductors based circuit. Don't you remember what happened with attraction motor? Taking the shortest route isn't always most practical thing to do in the long run and I will repeat now what I said than- reed relays are the most inconvenient things when dealing with precise timings especially at higher frequencies.

That being said I will help you as much as I can with little time I have to spare. The rest we can handle as before- contact me on ICQ or Skype.
