Abstract
Electronic system for calculating injection time in which an electronic unit with microprocessor receives as input a multiplicity of signals measured in the engine and a signal proportional to the engine load, for example a signal generated by a pressure sensor arranged in the intake manifold of the engine. The electronic unit comprises a circuit for compensating for the delay times due to the response inertia of the engine load sensor, the conditioning (filtering, conversion and processing) of the load signal and physical actuation of the injection. The electronic unit also comprises a circuit for the dynamic compensation of the 'film/fluid' effect.
