Abstract
A fuel injection assembly comprising a main structure (101) for mounting on an internal combustion engine, the main structure having one or more orifices (115) for injecting fuel directly into the combustion chamber of the internal combustion engine, and the main structure also having mounted thereon charge electrodes (105, 118) positioned to provide an electric field which passes through the flow of fuel, for charging fuel particles to improve atomisation. The main structure also has mounted thereon a spark electrode (104) adapted to provide a fuel ignition spark for the internal combustion engine. The main structure of the assembly is adapted for removable mounting, having a threaded portion (102) adapted to co-operate with a threaded aperture in the internal combustion engine, normally adapted to receive a convention spark plug.
