Two California inventors have designed and patented the ultimate flex-fuel and flex-combustion engine: an engine that can adapt in real-time to a variety of petroleum-, bio- or gaseous-fuels using the appropriate combustion mode, including spark-ignition, compression-ignition or HCCI variants. The design eliminates the last mechanical constraint for a totally electronically controlled engine, namely the cam shaft, and allows each cylinder to be independently fine tuned in real time for a wide range of power options. Possibilities range from boosting compression for more power to using air compression only (no fuel) for braking to even storing the compressed air for extra power later on. Now all they have to do is get someone with lots of money interested in developing it further.
