Abstract
A rotary internal combustion engine having multiple intermeshing rotors. Six radial lobes and six radial voids on the uniform rotors intermesh to form sealed volumes that are then compressed as the rotors rotate. The sealed volume is compressed into bevel chambers formed between the intermeshing rotors, and fuel injectors are positioned to inject fuel when the volume is under maximum compression and to maximize combustion. The combustion products are then exhausted as the rotors continue to rotate. An external supercharger compresses air prior to its introduction into the engine to increase the compression ratio. The supercharger also communicates pressurized air into the radial voids after exhaustion to purge any remaining combustion products.
