Abstract
The injector has two calibrated holes that deliver two jets of fuel into a zone into which there open out defined holes for passing air that are formed in a spray-generating adapter which is fed with air from a channel that is substantially at atmospheric pressure. The air-passing holes are distributed and oriented in such a manner that when steep pneumatic gradients are applied across the holes, at low or medium engine loads, one of the two sprayed fuel jets is deflected towards the other and mixes therewith to form a single jet confined in one only of the two intake manifold ducts, while at high engine loads both of them are fed. The injector is suitable for fitting to internal combustion engines fed by a multipoint injection installation and having two intake manifold ducts per combustion chamber.
