摘要：The device for regulating the fuel supply to an internal-combustion enginesupercharged by the exhaust-gas energy and acting on a suitable member, such as atleast one turbocharger unit, is of the type comprising an injection pump where the stroke

of the injection pistons is adjusted by a stop plate, the position of which is controlled as afunction of the air mass admitted into the cylinders of the engine in each cycle. The stopplate 8 is positioned by means of an electric motor 40 fed by an electronic computingand control circuit 53 sensitive to the air mass admitted into the engine cylinders in eachcycle, whilst its position is detected by a suitable electrical and/or electronic means, suchas a copying potentiometer 24. The invention is used for adjusting the flow of the

injection pumps as a function of the actual air mass admitted in each cycle, particularly forlean running at high power and a better richness setting during transient phases.
