Abstract
A fuel feed quantity control system of the so-called L-Jetronic system is described. The system is equipped with a Karman vortex air-flow sensor, at least one injector for feeding a fuel into an internal combustion engine, a controller for controlling the quantity of the fuel, which is to be injected, on the basis of intake air flow rate information from the air-flow sensor, and at least one operation parameter sensor. The controller also includes at least one additional control unit which serves to correct the quantity of the fuel, which is to be fed into the engine, in accordance with at least one operation parameter from the operation parameter sensor and frequency information outputted from the air-flow sensor. The quantity of the fuel, which has been determined based on an output from the air-flow sensor, is corrected by the controller in accordance with changes in kinematic viscosity of the atmospheric air.
