FORFARANDE OCH ANLEGGNING FOR BRENSLEINSPRUTNING I EN FLERCYLINDRIG FORBRENNINGSMOTOR

摘要

A fuel injection system which injects fuel intermittently and in which the periods of time for which fuel is injected are determined by the rate of flow of a control fluid. This rate of flow is in turn controlled by an air valve located in the engine air intake to produce a control depression and adjustable to maintain that depression substantially constant. Preferably, the control fluid is air flowing from atmosphere into the control depression region, and the system preferably also includes a mechanism for adjusting the periods of time for which fuel is injected to compensate for variations in the control depression.
