Abstract
A monitoring system and method for detecting clogging through fouling of an air filter () of an internal combustion engine () comprising a differential pressure sensor means () for determining a differential pressure between an ambient environment and a position directly downstream of the air inlet filter. The system further comprising at least one exhaust flow sensor means () for determining the exhaust flow, and a controller () which is communicatively connected to each of the sensor means for processing information therefrom. The controller is arranged for determining a first filter resistance coefficient based on, at least, a measurement of the differential pressure, and the exhaust flow. The system is arranged for, using the controller, to calculate a second filter coefficient based on the historic evolution of the first filter coefficient, the controller further arranged for comparing the second filter coefficient to a boundary value, and generating a clogging alarm signal when the second filter coefficient exceeds said boundary value.
