Fuel injection assembly
First Claim
1. A fuel injection assembly comprising a main structure for mounting on an internal combustion engine, the main structure having a number of orifices for injecting fuel directly into the combustion chamber of the internal combustion engine, the main structure also having mounted thereon an electrode structure for atomizing and igniting the fuel including a spark electrode adapted to provide a fuel ignition spark for the internal combustion engine;
- characterized in that the electrode structure includes charge electrodes;
means positioning said charge electrodes to provide an electric field which passes through a flow of fuel for charging fuel particles in the flow to improve atomization; and
said main structure having three electrical connectors adapted to be connected to three different potentials, with means connecting said three connectors to said charge electrodes and said spark electrode to allow provision of a relatively low potential difference for atomizing the fuel and a relatively high potential difference for igniting the fuel.

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.
