ABSTRACT:
A dual fuel injector has a body in which first, second and, optionally, third flow passages are provided. The first passage feeds liquid fuel to a first ring of outlet orifices which discharge into the second passage. The second passage leads to a second ring of outlet orifices which are aligned with orifices in the first ring and which are of greater cross-sectional area than the latter. The orifices of both rings lie on axes which are disposed at an acute angle (e.g. 45.degree.) to the longitudinal axis of the body so that a conical discharge of fuel and air is obtained in use. The second passage is an air passage when liquid fuel is being injected and may be an air passage or a gaseous fuel passage when the optional third passage is employed and the injector is in its gaseous fuel injection mode.
