Abstract:
1. A toroidal internal combustion engine comprising: a first crank assembly having first pistons secured thereto, the first crank assembly further having formed thereon a first interference structure; a second crank assembly having second pistons secured thereto, the second crank assembly having formed thereon a second interference structure; a housing to house the first crank assembly and the second crank assembly, a toroidal chamber being defined by the housing, the first crank assembly and the second crank assembly, each of the first pistons being interposed between a pair of second pistons to define variable volume compartments in the toroidal chamber, one of the variable volume compartments being a combustion compartment; a drive shaft, the first crank assembly and the second crank assembly being operationally coupled to the drive shaft to alternately turn the drive shaft in a pre-determined direction, the housing being operationally coupled to the first crank assembly and to the second crank assembly to prevent the first crank assembly and the second crank assembly from rotating in a direction opposite the pre-determined direction; and a system to alternately stop a rotation of the first crank assembly upon one of the first pistons being in a pre-determined position and a rotation of the second crank assembly upon one of the second pistons being in the pre-determined position, the system having a first member and a second member to interfere respectively with the first interference structure and the second interference structure, the first member to temporarily stop the first crank assembly in the pre-determined position upon the first member interfering with the first interference structure, the second member to temporarily stop the second crank assembly in the pre-determined position upon the second member interfering with the second interference structure, the system further having an electrical circuit operationally connected to the first member and to the second member, the electrical circuit to generate an ignition signal to ignite a fuel mixture present in the combustion compartment in accordance with one of an interference of the first member with the first interference structure and an interference of the second member with the second interference structure respectively.
