ABSTRACT:
A toroidal engine [20] is provided having opposed rotor assemblies [45] supporting pistons [47] arranged on each rotor assembly [45]. Part toroidal working chambers are formed between the pistons [47] in which a combustible mixture of air and fuel is compressed and then ignited at minimum working chamber volume forcing the then active pistons [47] and rotor assemblies [45] to accelerate. The rotor assemblies drive a planetary member [50] for rotation about its axis through a sliding pin connection [56]. The or each planetary member [50] is supported on a crankpin [51] of a crankshaft [40] and is integral with a planet gear meshed with a sun/annulus gear [53] centered on the crankshaft axis. The crankshaft [40] may be arranged to counter-rotate relative to the rotor assemblies [45] by meshing the planetary member gear [52] with an annulus gear [53] or in the same direction by meshing with a sun gear.
