Abstract

An atomisation apparatus comprising: a fluid delivery conduit (100) having a first opening for communication with a source of fluid, and one or more orifices (110) for delivery of fluid; and a gas delivery conduit (200) having a first opening at a first end for communication with a source of gas, and a hole (210) for delivery of gas, wherein 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), whereby, in use, fluid delivered through the one or more orifices (110) passes through the hole (210). Such an atomisation system can be used in an internal combustion engine comprising a bypass passage (320) which bypasses a throttle and via which gas is supplied to a fuel injection system (300/ 330).
