Abstract

An atomisation apparatus is provided, the atomisation apparatus comprising a fluid delivery conduit 100 having a first opening for communication with a source of fuel and one or more orifices 110 for delivery of fluid. A gas delivery conduit 200 has a first opening at a first end for communication with a source of gas, such as air, and a hole 210 for delivery of gas. The gas delivery conduit 200 surrounds at least part of the fluid delivery conduit 100 such that the one or more orifices 110 are aligned with the hole 210. In use fluid delivered through the one or more orifices passes through the hole 210. The system may be used in an internal combustion engine having a bypass passage which bypasses a throttle and through which gas is supplied to a fuel injection system to entrain and/or atomise fuel delivered by the fuel injection system. A control valve may be provided to control the flow of gas through the bypass passage. Also disclosed are an associated internal combustion engine, control valve and fluid dispensing arrangement.
