Interesting ignition system

[Andy M]

i concur, but theres never a shortage of people with money to burn, good intentions and no mechanical or technical knowlege to figure out that theyre getting spanked!!!!

I think we should invent one. If needs to be plausible, probably based on old technology and yet if you are lucky at least does no real harm. Better still it has to have a good sales pitch.

The gearbox snake oil has that demo where they file a bit of rod held in a lathe with and without the PTFE. Looks good on the table top, probably does nothing that bad in your gearbox for years. The customer is happy and won't even remember you when something does go bang.

Splitfire plugs have to be better in the customers heads because all their mates are busy drilling holes in their heads to fit a second plug. Platinum and Iridium conduct better than copper alloy so people will believe the picture on the box. By the time the electrode drops into the head or people work out their fuel use the supplier can be well out of the picture.

The lump of lead to drop in your petrol tank came with a brochure about how they were sent to Russia for use in Hurricane fighter aircraft.

Anyone want to buy an MZ power band?

Do you think the lump of lead would help convert my MZ two stroke for unleaded use then ?

[JOOLZ]

Of course not, a lump of lead in the tank wont do a thing, I can of course sell you the lead piston conversion  for the low low introductory price of $400, this will allow you to go lead free and have the benefit  of the extra weight pressing down on the piston which increases the hp by an extra 25%

Two stroke leaded conversion being the equivalent of Splitfire Sparkplugs and Snake Oil.

diesel spark plug? tell me he doesnt think that deisel engines need a spark plug?

One of my current projects is a spark plug driver for a diesel, the plug doesn't look anything like that though. I'll give you a clue - the spark plug isn't in the cylinder head.

[Andy M]

I know, It's a kit that lets you mount the spark plug in the piston. By having the spark travel up and down with the flame front a more even burn gives more power and better MPG 

Having the HT lead going in via the crank case brather also makes it more waterproof

Hmmmmm Andy, but dont you think the oil residue when its switched off would foul the plug?? You would also need to make some sort of solenoid operated one way drain valve, just next to it in the piston. In order to stop destroying the sump oil, it could be an idea to have a small port at the bottom of the stroke to alloy this diesel oil residue to drain to a catch can and eventually be reused. you would only need to hand crank the donk a couple of times to allow each cylinder to discharge the waste. Cool Runnings.

[Andy M]

Indeed. Also it will require something we can keep selling, say a special anti fouling oil that can simply be added to the fuel at say a 50:1 ratio?

As it is no longer a plain old spark ignition it needs a better name. How about Super High Intensity Transmission Element or S.H.I.T.E for short?

Lol, no its in the exhaust - used to fire a burner to heat the exhaust gasses up to regenerate the DPF.

no no no... the answer for correct spark timing and intensity is......

the positive terminal of the plug is in the head... the spark is then created between the +ve terminal and the piston... so care has to be taken to ensure that the HT power is controlled so that the a spark is generated as the piston approaches TDC and a gap of 25thou.

the plug can be adjusted in the head by the use of shims, to get the correct timing/spark intensity

of course there will be a silly thing called spark erosion taking place, which left unchecked could put a hole in the piston... but hey... no gain without pain...... a half pound lump of something on top of the piston... known as a sacrificial anode should do the trick...
