Abstract
A fuel injector for supplying liquid fuel to an air inlet manifold of a spark ignition engine has a fuel-inlet, an outlet defined in a tubular component mounted in a tubular part of the injector body, and at least one orifice formed in a valve seat member downstream of a valve member. The tubular component is spaced downstream from the valve seat member. An air circulation duct is defined between the tubular component and tubular part, so that spray of fuel flowing through the outlet draws air through the duct to minimize dribble of fuel from the injector.
