Re: Lower size limits of the internal combustion engine

A typical piston gas engine is about 3.0 L of internal volume. Of

lower-limit to this size. I woul think that there could never be a
4-CYCLE engine that is quite small, since there would not be enough
mass/force generated to initiate the compression cycle.

What do you think?

Is a 4 cylinder, 4 cycle, 0.061 cubic inch engine small enough for you?

The same guy also built a 5 cylinder, 4 cycle radial with the same
displacement.
