Abstract
A bi-fuel spark ignition engine is disclosed. The engine can operate on either gasoline, natural gas or a combination of the two. The amount of each fuel that is used by the engine is based on the engine's operating parameters, such as RPM and torque. In some embodiments, the operator can provide input, such as the availability of natural gas, which affects the operation of the engine. In some embodiments, an anti-knock agent is used to prevent knock at higher values of torque.
