Strewth!

Arthur, Don't wish to gloat but that is a n air cooled Carrette Gas engine of which I have the water cooled version.

I agree that it isn't a flame gulper but it looks to me to be a flame ignition gas engine with the ignition flame sucked in an open port on the side as the piston starts to descend. The problem with these is they were designed to run on town gas & will not run on any other gas. I sold mine about 12 years ago. (I wish I hadn't seeing modern prices)

Dave, You say it runs only on town gas. I take it the town gas you refer to is not what people use now.

starts to descend.

Yes, you could run it, but you'd have to use bottled hydrogen gas. Natural gas or LPG are no use, as Dave correctly says. Same goes for carrier flame ignition engines, the ignition burner has to use hydrogen even if the main fuel supply is LPG.

Hi Arthur, This one is a little different to the one I owned but it does seem to have the ignition flame on the side of the cylinder like the one I owned. I (& others) tried for years to get it to run but the ignition flame was always sucked out. We tried various gasses but couldn't get the coal gas it was designed to run on.

Thank you for that interesting insight, Philip.

There's more to these little devils than meets my eye.

Makes the "recalcitrant blowlamp" problems of the Petter S seem quite trivial!

Now, where can Martin buy some hydrogen :-)

Regards, Arthur G

Hi Arthur, I have posted a picture of an article about the engine I owned. I can't find the actual picture I took.

I should have said that town gas was a mixture of mainly hydrogen and carbon monoxide :-)

Why, from BOC Industrial Gases of course, but I don't think its cheap!

Gentlemen, mine is fitted with a hot tube which is heated by a miniature bunson burner, surely if I restricted the flow of LPG it should work like the bigger gas engines that now run on LPG ?

Martin P

Hi Martin, Hot tube ignition is a totaly new ball game! The engines I am talking about draw gas into the cylinder as the piston starts to descend until it passes a hole in the side. It then sucks the flame in, lighting the gas & the explosion completes the stroke.

Sound of hobby horse entering stage left.... Please chaps lets have some snipping please. This thread started at 1kb and is now 4kb per item. thanks Roland

Sorry Roland, Just name and shame me, it is I, I do it all the time, wrist slapped, I'll try and remember :-((

Martin P

Bugger I've just done it again :-))

I remember reading that the inverted Crossley at the Anson is ignited with expensive hydrogen, but actually runs on LPG.
