Abstract
Fuel injectors for an internal-combustion engine are controlled by duration-modulated pulses whose width depends on a plurality of parameters, namely the rotational speed and the temperature of the engine and the air pressure at two points of the intake manifold. The width of the modulated pulses depends on the magnitude of one parameter and on binomials of the other parameters. A computer formed by cascaded operational amplifiers with fractional gain and adding circuits establishes the variable operating period of the injectors which are provided with two coils, i.e. a premagnetization coil energized by a constant-duration pulse and a control coil receiving the duration-modulated pulse in staggered relationship with the former.
