Atmospheric engine
Atmospheric engine
Complete set of new castings, stock material, fixings, pair of finished bevel gears and drawings for an unusual atmospheric engine, to the design by Bruce Engineering of Middlesex, England. The induction stroke draws in a mixture of air and gas with ignition provided by a flame drawn through a port in the cylinder. A power and exhaust stroke follows, without compression of the mixture (hence "atmospheric" engine).

This engine is still in production and parts are available.

1 x 1 bore/stroke
Twin 5 inch diameter flywheels
