Electromagnetic interference (EMI) or radio frequency interference (RFI) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source (non-resistor type spark plug). RFI is any unwanted radio frequency signal, which interferes with another, desired radio frequency signal. Ignition system for RC gas engine in most cases causes RFI. read more...
Gas engines use spark plugs while nitro engines use glow plugs to ignite the fuel/air mixture. This is why RC gas engines require on-board ignition systems which provide electricity for the glow plug at exactly the correct time. There's two varieties of electronic ignition systems used with gas engines. read more...
