Abstract

An intermittently actuated fuel injector 10, 11 is mounted on the throttle body 20 of an internal combustion engine 15 so as to spray atomized fuel into the throttle bores 26, 27 of a twin-choke carburettor against throttle blades 30, 31. The atomized fuel is mixed in, and further atomized by, the turbulent high velocity air flowing in the gap between the walls of the throttle bores 26, 27 and the edges of the throttle blades 30, 31. At wide open throttle position, part of the fuel plates on surface 29. It is then mixed and further atomized by the air which shears the plated fuel off a discontinuous edge of surface 29. Differences in the air/fuel ratio between cylinders are reduced by achieving injections at a predetermined advance before top dead center of the cylinders. The injectors may be co-axial with the throttle bores 26, 27 and inject into secondary venturis upstream of the throttle blades 30, 31. The injectors may provide all the fuel required by the engine or may function as power jets in a conventional float-chamber fed carburettor.
