摘要： A method for detecting whether an injector with a valve controlled by a PWM signal of an SCR system is clogged, the SCR system including a rotary positive-displacement pump driven by a motor and pressure of which is controlled by a controller that continuously measures rotational speed of the motor and pressure at an outlet of the pump. During operation of the SCR system at a given pressure: the associated average rotational speed is measured; the speed is held at the measured value; a curve of a change in pressure is compared to reference curves stored in a memory and a condition of the injector, for example whether the injector is clogged or not, is deduced therefrom.
