IC engine fuel injection equipment - enables air encirclement of fuel jet with connection to air suction line via suction conduit between two throttle valves

摘要

The fuel injection equipment is for a mixture compressing IC engine, and has a fuel injection valve fitted in the air suction conduit of the engine. Air is brought around the fuel jet via a suction pipe branched off the air suction line, and in this latter line is fitted a throttle valve operable by the driver. The throttle valve (7) is fitted upstream of the branch of the suction pipe (6) from the air suction line (1), and additionally an axuiliary throttle valve (8) is fitted downstream of the branch of the suction pipe from the air suction line. The auxiliary throttle valve is connected to the main such valve via a coupling element (9) with a spring (10). The auxiliary throttle valve (8) is closed during no-load running, and is controllable dependent upon an anti-slip regulating signal. USE/ADVANTAGE - With mixture compressing IC engines, to increase the amt. of air for mixt. with fuel without affecting the no-load regulation of the engine.
