Tom,

Yes really nice engines! Will have to look up atkinson cycle, I was just reading top gear magazine the other day and I see the toyota prius uses an atkinson cycle engine - must be more efficient? How does the non compression one work?

Thanks Guys.
Chuck    Economic Motor Co. built  These under the Hopkins patents
Nick   I had no plans just a good picture. I am not sure how the original one worked .The one I built has a normal exhaust cycle with popit valve. The intake valve is atmospheric popit. On the intake stroke it sucks air and gas for about 1 to 2 inches of the stroke and then the plug fires and the rest of the stroke is the power stroke. The fuel is propane and leaves a glue like substance in the cylinder which sticks the intake valve over night.  :doh:   Tom
