ABSTRACT:
A system for assisting in the atomisation of liquid particles conveyed in a gas stream flowing along a flow path having a rigid boundary, said system involving the creation of one or more shock waves in the gas stream. In a preferred embodiment, the system comprises a fuel injection nozzle (10) comprising a fluid flow passage (43) terminating at a discharge orifice (15) and incorporating a delivery port (33) defined between a valve seat (31) and a valve member (23) movable with respect to the valve seat for opening and closing the delivery port. Fuel is delivered along the fluid flow passage (43) into a combustion chamber through the discharge orifice (15) upon opening of the delivery port (33). The valve member (23) devines an inner boundary surface (47) of the flow passage (43) and the valve seat (31) defines at least part of an outer boundary surface (45) of the flow passage (43). The inner and outer boundary surfaces (47, 45) are configured to generate one or more shock waves in an air-fuel mixture flowing at supersonic speed therebetween.
