non compression gas engine

this is a non compression gas engine, build from scrap parts, this was an experiment.
it is a 2 stroke, intake atmospheric till 75 degrees, ingition at 76 degrees, exhaust opens at 185 degrees and keeps open till 360 degrees.

So the contact points are triggering the Relais that is triggering the 12V input side of the Transformer? If so, I must say this is the most simple homemade ignition I ever heard of.- Very good and congratulations- (Why the heck I did not have the same idea, but simple ideas are often hard to get). If you say it is 220V in your country (and if you say "indeed") than this should be the UK?

@XELA2T

the contactpoints are triggering a 12Volt 50Hz AC current to the relais, so if the contactpoints are closed the relais "buzzes" on the 50HZ. the other side of the relais is the "switch" for the current to the tranformer, so this opens/closes 50 times/second.

So the transformer(my ingnition coil) gets 50 time/second his 12Volt input.

It is a transformer which transforms from 220V to 12Volt, i use it the other way, so i put 12Volt on the 12Volt side.

On the 220Volt side i get my spark.

Ah, ok now I got you right, very good, the only thing you have to get used to while adjusting this ignition I may guess is that the spark occurs when the points are closed unlike with a conventional point/coil ignition.

@XELA2T

Yes, but that is no problem for me. thanks for your posts.

very nice for a  "build from scrap" engine.

Looks like this is a home made contact point coil ignition. If so, please tell me what voltage, and where the transformer is from. (Micro wave)??

Best regards

@XELA2T ignition is indeed homemade, it rund on 12 volts, its a regular (for our country) transformer 220-12 volts. I put the input on the 12Volt side, inbetween a relais and my contactpoints, e voila, I get a nice spark on the 220V side.

And the engine does not overheat? how long it can run without stopping? which spark plug is used here?

@douro20

yes, it is a kind of lenoir engine

[douro20]

I get it that this is a Lenoir cycle engine?
